RESUMO

Manipulation of skin biogeography has been the subject of study by the present authors for a very long while. Previous description and report identified the benefical application of skin microbiota transplantation (SMT) by the same researcher group, whom described unenriched skin microbiota transplantation at clinical veterinary practice for the first time among dogs. This study to our knowledge again for the first time reported herein aimed to investigate Un-smt application for treatment of feline atopic skin syndrome (FASS). This novel treatment intervention was performed similarly to previous description and methodology by use of Nivea Refining Clear-Up Strips (Ni-RcUs) either in autologue or heterologue route. Clinical biomarker for detecting the efficacy of Un-smt via Ni-RcUs evolved epidermal corneometric analytes (i.e. epidermal hydration and pH), relevant clinical scores The Feline Dermatitis Extent and Severity Index (FeDESI) and Visual Analogue Scale (VAS pruritus) and clinical observations performed weekly, at least. Both FeDESI and VAS pruritus scores were changed in relationship with smt. Pre-treament day 0 FeDESI scores (median ± SE) (72.5 ± 9.34), were significantly (p=0.001) higher than scores on day 10 (13.5 ± 2.55) switching the severity of the disease in all cases. Besides day 0 VAS pruritus scores were 6.0 ± 0.49 (median ± SE) (prior to treatment), whereas owner VAS pruritus score was decreased to 2.0 ± 0.34 (median ± SE) significantly (p=0.001). There were no side effects attributable to treatment applications. All cases were monitored for 6 months after completion of treatment in which no recurrence was observed. As a preliminary conclusion with selected number of cats with FASS, Un-smt with Ni-RcUs should be novel strategy for manuplating skin microbiome with treatment success.

RESUMO

The study aimed to investigate the levels of arginine, symmetric dimethylarginine (SDMA), and asymmetric dimethylarginine (ADMA) in dogs with canine leishmaniasis (CanL) and their relationship with some renal and cardiovascular parameters. A total of 60 dogs were enrolled, including 40 with CanL and 20 healthy controls. The CanL group was divided into four stages based on clinical and laboratory findings. The levels of plasma arginine, SDMA, and ADMA were determined by high performance liquid chromatography (HPLC). The data from the healthy group were compared with those from the CanL group, and according to the stages. In dogs with CanL, systolic and diastolic blood pressure, plasma creatinine, cystatin-C, phosphorus, potassium, and low-density lipoprotein concentrations, the urine protein/creatinine ratio, the amount of nitric oxide, and creatine kinase-MB activity were higher, while the high-density lipoprotein concentration was lower compared to healthy controls. The concentration of arginine was low (p < 0.05) and the levels of ADMA (p < 0.001) and SDMA (p < 0.05) were high in dogs with CanL. There were no statistically significant differences in arginine concentration among the different stages of CanL. However, the concentration of plasma ADMA was higher in all stages of CanL compared to the healthy group, and the concentration of plasma SDMA was higher in Stage IV compared to the healthy group and Stage III. The present study demonstrates for the first time a decrease in arginine concentration and an increase in ADMA concentration in dogs with CanL. The increase in SDMA concentration in dogs with CanL was consistent with previous studies. However, compared to other renal parameters, SDMA exhibited limited performance distinguishing between clinical stages of CanL. These findings could be a source for future diagnostic and therapeutic studies to explain the renal and cardiovascular pathophysiology of CanL. Additional clinical studies that include treatment and patient follow-up with an assessment of the acute phase response are needed to provide a more detailed understanding of the changes observed in dogs with CanL.

RESUMO

Visceral Leishmaniasis (VL) and Monocytic Ehrlichiosis (ME), which are an important zoonotic diseases of dogs, causing multiple organ dysfunction and has a poor prognosis when not interfered. In this study, it was aimed to investigate the cardiovascular injury that develops in dogs that co­infected with VL and ME with cardiovascular biomarkers and echocardiographic parameters. The animal material of this study was consisted of 14 owned dogs in total; 7 diseased dogs which were determined to be co­infected with VL and ME according to the results of clinical examination and rapid test kits, and 7 healthy dogs, which were determined to be healthy as a result of the same examinations. As a result of echocardiographic examinations, decreased left ventricular cytolic and diastolic diameters (LVIDs, LVIDd), fractional shortening (FS) and increased ratio of left atrium to left aortic root diameter (LA/Ao) values were determined in the Co­infected Group compared with the Healthy Group. Also, as a result of biomarker analysis, higher cTnI) D­dimer and NT­proBNP levels were detected in the Co­infected Group. In conclusion, considering studies of dogs infected with VL and/or ME alone, it was concluded that similar cardiovascular injury develops in dogs co­infected with VL and ME.

RESUMO

PURPOSE: Canine ehrlichiosis is an important tick-borne disease of dogs worldwide. In the present study, we aimed to determine the serum total antioxidant capacity (TAC), malondialdehyde (MDA), nitric oxide (NO), superoxide dismutase, (SOD), glutathione peroxidase (GSH-Px), adenosine deaminase (ADA) activity and serum protein profiles in dogs affected with naturally acquired ehrlichiosis. METHODS: The animal materials had been consisted of ten dogs naturally infected with Ehrlichia canis, and ten controls negative for Ehrlichia canis. TAC, MDA, NO, SOD, GSH-Px, ADA activity and TP, ALB, GLOB levels were measured in sera of the animals. The serum protein concentrations were measured by autoanalyzer. The electrophoretic profiles of serum total protein were determined by native polyacrylamide gel electrophoresis (Native-PAGE). RESULTS: In dogs with ehrlichiosis, decreased TAC (P < 0.05) and GSH-Px (P > 0.05) levels were determined. However, NO (P > 0.05), SOD (P < 0.05), ADA (P > 0.05), MDA (P > 0.05), TP (P < 0.05) and GLO (P < 0.05) levels were found as increased in the Ehrlichia positive dogs. ALB levels were decreased without a statistical significance (P > 0.05). ALB, α1 and ß2 globulin strip densities were found as decreased in native-PAGE, while ß1 and γ globulin strip densities were significantly increased in the E. canis positive group when compared to the control. CONCLUSION: It was determined that the oxidative stress decreased high antioxidant activity in dogs naturally infected with E. canis, and consequently, pro-oxidant and antioxidant defense and serum protein profiles were affected. It was thought that antioxidant supplementation could be beneficial to the treatment of the disease.

RESUMO

BACKGROUND: Plasma citrulline (CIT) concentration is considered to be a reliable marker of functional enterocyte mass, primarily in humans. However, information about CIT levels along with related metabolites, arginine (ARG), nitric oxide (NO), and ammonia in neonatal calves are lacking. OBJECTIVES: To compare plasma CIT, ARG, NO, and whole blood ammonia concentrations in neonatal calves with acute diarrhea with those in healthy calves and to assess their possible relationships with diarrhea-related criteria. ANIMALS: Seventy neonatal calves (60 with acute diarrhea and 10 healthy). METHODS: Observational case-control study. Diarrheic calves were classified into subgroups on the basis of etiology, severity of diarrhea, degree of dehydration, and systemic inflammatory response syndrome (SIRS) status. Plasma CIT and ARG concentrations were measured by liquid chromatography/tandem mass spectrometry. RESULTS: Plasma CIT (median [range]: 67.5 [61.9-75.4] vs 30.1 [15.0-56.1] µmol/L) and ARG (170.7 [148.5-219.5] vs 106.1 [54.4-190.7] µmol/L) were lower and plasma NO (4.42 [3.29-5.58] vs 6.78 [5.29-8.92] µM) and blood ammonia concentrations (28.7 [26.1-36.9] vs 59.8 [34.6-99.5] µmol/L) were higher in the neonatal calves with diarrhea (P < .001). Plasma CIT (ß = -0.29, P = .02), ARG (ß = -0.33, P = .01), NO (ß = 0.55, P < .001), and blood ammonia (ß = 0.63, P <.001) were affected by SIRS status. Except for ammonia (0.52), the effects sizes for severity of diarrhea and degree of dehydration were small (ηp2 ≤ 0.45) for CIT, ARG, and NO. CONCLUSIONS AND CLINICAL IMPORTANCE: The changes in these variables might have diagnostic, prognostic, and therapeutic value in diarrheic neonatal calves.

RESUMO

Abstract Objective. The present study was conducted to measure D-dimer concentrations and assess their value in disease activity in dogs with giardiasis. Furthermore another purpose was to analyze correlation between cyst excretion and D-dimer levels to those of dogs naturally infected with Giardia sp. Materials and methods. D-dimer analysis were performed in three groups of dogs; (i) 15 dogs with giardiasis to those of treated with secnidazol, (ii) 10 dogs with giardiasis, left untreated as control group, then were compared to those of (iii) 17dogs without giardiasis, used to detect reference ranges for D-dimer values as control group. was a correlation between D-dimer levels and logarythmic cyst counts. Results. The D-dimer range in healthy dogs was <0.1 mg/L. In dogs with giardiasis, the D-dimer concentrations were greater than those of healthy dogs (p<0.05) and (p<0.01), respectively. The mean initial plasma D-dimer level was 2.84±0.50 and 2.99±0.61 ng/L in treated and untreated control groups. At the final follow-up evaluation on day 10 was 0.27±0.50 and 2.14±0.61 ng/L, in treated and untreated control groups, respectively, which was significantly lower in treated group (p<0.001). The area under curve (AUC) of the receiver operating characteristics for d-dimer was 0.922 (z-value = 12.977, p<0.0001). (95%CI: 0.780-0.885). At a cut-off value of 0.1 ng/L, the D-dimer measurement had a sensitivity of 87.2%, a specificity of 90.9%. Conclusions. As a result D-dimer concentrations measured in giardiasis support the probable link between probable pro-thrombotic and inflammatory condition.

Además, otro objetivo fue analizar la correlación entre la excreción de quistes y los niveles de D-dímero a los de perros naturalmente infectados con Giardia sp. Materiales y métodos. El análisis del dímero D se realizó en tres grupos de perros; (I) 11 perros con giardiasis tratados con secnidazol, (ii) 10 perros con giardiasis, no tratados como grupo control, luego se compararon con los de (iii) 17 perros sin giardiasis, utilizados para detectar rangos de referencia para el dímero D Valores como grupo de control. Resultados. El rango del D-dímero en perros sanos fue <0.1 mg/L. En perros con giardiasis, las concentraciones de dímero D fueron mayores que las de perros sanos (p<0.05) y (p<0.01), respectivamente. El nivel medio inicial de dímero D plasmático fue 2.84±0.50 y 2.99±0.61 ng/L en los grupos de control tratados y no tratados. En la evaluación final de seguimiento al día 10 se obtuvieron 0.27±0.50 y 2.14±0.61 ng/L, tratados y no tratados, respectivamente, que fue significativamente menor en el grupo tratado (p<0.001). El área bajo curva (AUC) de las características de funcionamiento del receptor para el dímero d fue 0.922 (valor z = 12.977, p<0.0001). (IC del 95%: 0.780-0.885). Con un valor de corte de 0.1 ng/l, la medida del dímero-D tenía una sensibilidad de 87.2%, una especificidad de 90,9%. Hubo una correlación entre los niveles de D-dímero y los recuentos de quistes logarítmicos. Conclusiones. Como resultado, las concentraciones del dímero D medidos en la giardiasis apoyan el probable vínculo entre la probable condición pro-trombótica e inflamatoria.

RESUMO

Abstract Objective. In the present study the aim was to establish the efficacy of 30 mg/kg single dose secnidazol in calves naturally infected with Giardia duodenalis. Materials and methods. In an attempt to perform original study a total of 18 calves, from various breed, age and of both sexes were enrolled. Diagnosis was based on detection of trophozoit and/or cysts on fecal flotation among calves naturally infected with G. duodenalis, besides by use of rapid diagnostic test kits working with solid phase immunochromatographic principles and β-giardin nested- Polymerase Chain Reaction aplication. Cyst count per gram of feces were performed among days 0, 3, 7 and 10 in all cases. On days 0 and 10 hematological (WBC, RBC, HCT, MCHC, PLT) and serum biochemical (ALT, AST, creatinine, urea) values were determined. Results. Two different groups of calves composed of secnidazole group (n:9) and control group (n:9) were enrolled. Among calves enrolled in treatment group secnidazole was administered at a single dosage of 30 mg/kg perorally on day 0, whereas control group were left without any active ingredient. Cyst count per gram feces, hematological and serum biochemical values were analyzed among groups and intragroup comparisons. Giardia duodenalis assemblage A3 was detected in all 18 calves. On days 3, 7, and 10 there was significant (p˂0.001) reduction in cyst excretion; whereas evaluation of mean geometric cyst excretion revealed 100% reduction on days 7 and 10. Among two group statistical analysis of hematological and serumbiochemical variables revealed no statistical significance on days 0 and 10. Conclusions. In conclusion secnidazole at a single dose of 30 mg/kg might be practically appliable, reasonably priced, safety, completely effective and causing rapid recovery treatment protocole for therapy of calves with Giardiasis.

RESUMO

ABSTRACT Objective. The purpose of the present study was to test the hypothesis that cardiac alterations participate within different stages of CVL. Materials and methods. Dogs were diagnosed with CVL, were classified as follows; group I (mild disease), group II (moderate disease), group III (severe disease), group IV (very severe disease) and group V included healthy controls. Results. Ig G antibodies against Leishmaniasis in group as tested by IFAT, were deemed 1/64 to 1/16000 among infected groups. Considering the cTnI levels, there were significant differences (p=0.018) between stage IV (group IV) and healthy control group, besides between group IV and group I. Considering D-dimer levels, there was difference between healthy control group and group II, III and IV (p=0.005). Regareing NT-pro BNP levels, there were differences between healthy control group and stage III, IV, besides between stage I with stage III, IV (p=0.000). Conclusions. The results showed that levels of cTnI, Nt pro-BNP and D-dimer were higher in dogs infected with CVL in contrast to healthy dogs, in which levels of those biomarkers were below detection limits. Obtained results suggested the possibility of cTnI and NT pro-BNP as markers for cardiac damage and D-dimer as a supportive tool for a diagnosis of probable thromboembolism in dogs with CVL.

RESUMO

This study aimed to evaluate the acute phase response (APR) through haptoglobin (Hp) and serum amyloid A (SAA) concentrations in serum and to examine the correlation between these acute phase proteins (APPs) and oocyst shedding using experimental Cryptosporidium parvum (C. parvum) infection model in neonatal lambs. Twenty lambs were divided into two equal groups: group CON remained uninfected as negative control and lambs of the group EXP were inoculated orally with 1×106C. parvum oocysts. Blood and faecal samples were obtained from both groups before colostrum intake and prior to inoculation (day-1), and at 2, 6, 13, and 20days post-inoculation (dpi). The serum concentrations of SAA increased following the experimental infection of lambs with C. parvum, the difference being statistically significant from pre-inoculation levels at 2 dpi, while significant increases in serum concentration of Hp were observed at 2 and 6 dpi. At the same occasions, serum concentrations of both APPs were significantly higher in the C. parvum-infected lambs compared to the healthy control lambs. A moderate positive correlation (rho=0.67; p< 0.001) was observed between serum Hp concentration and oocyst count (OPG),whereas the serum SAA concentration didn't significantly correlate with OPG (rho=0.18; p>0.05). In conclusion, the results of the study shed some light on APR due to C. parvum infection in neonatal lambs.

RESUMO

The purpose of the present study was to investigate the prevalence and molecular characterization of Giardia duodenalis among dogs in Aydin, Turkey. A total of 473 faecal samples from dogs were collected. The overall prevalence of G. duodenalis was 18.8%. Higher infection rates were observed in dogs younger than three months old, from shelters, and with diarrhoea. Faecal samples of 89 dogs, diagnosed Giardia-positive by microscopy, were found positive by nested PCR. The ß-giardin nested PCR assay revealed assemblage B in all samples (100%), whereas 38 of the samples were mixed with assemblage A (42%). Sequence analysis of isolates indicated sub-genotypes A3 and B4 which have been previously detected in human isolates from Turkey. The results of the present study indicated the relatively high prevalence of giardiasis and the presence of the zoonotic sub-genotypes suggesting the important role of dogs as potential reservoirs of human infections.

RESUMO

ABSTRACT Objective. To determine whether short term supplemantation at two levels (1 or 2 g/kg) of clinoptilolite (CLNP) in the colostrum of dairy calves had any effect on total weight gain (TWG) and mean daily gain of weight (mdwg). Materials and methods. A total of 24 clinically healthy calves without diarrhea were assigned in a subset of three major groups of calves were studied: group I (n=8) received colostrum with clnp at the rate of 1/kg started immediately following calving at 12 and 24 hours, for a total of 2 doses. Group II consisted of calves (n=8) receiving colostrum with clnp at the rate of 2/kg within the same interval as the first experimental group. The last group III, which served as control, received solely colostrum. Results. Group had significant effect on weight (kg) of Holstein calves [twg (mean±SE)- control: 12.66±0.349, group I: 14.73±0.414, group II: 14.19±0.468, p<0.01; mdwg (mean±SE)-control: 0.338±0.0155, group I: 0.396±0.0189, group II: 0.397±0.0196, p<0.05]. There was a significant difference observed for twg (p<0.01) and mdwg (p<0.05) among control group and both clnp treatment groups. Conclusions. The results showed that the addition of both levels of clinoptilolite administration via colostrum appeared to enhance twg and mdwg in newborn calves without having any observable adverse effect.

RESUMO

OBJECTIVE: The purpose of the study was to investigate the oxidative status and lipid profile among dogs at different stages of visceral leishmaniasis (VL). METHODS: Dogs with VL were divided into four groups according to the classification reported by the Leishvet group: stage I (n=9), stage II (n=11), stage III (n=6), and stage IV (n=6); these dogs were compared to healthy control dogs (n=14). The lipid profile [high-density lipoprotein (HDL), low-density lipoprotein (LDL), cholesterol, and triglyceride levels) and oxidative status [total antioxidant capacity (TAC), total oxidant status (TOS), and paraoxonase-1 (PON-1) activity] were evaluated. RESULTS: Compared to the control dogs, significant increases in the TOS and the LDL level and decreases in PON-1 activity and the HDL level were determined among the dogs at all stages of VL (p<0.05). No significant differences were found in the TAC and the cholesterol and triglyceride levels among the groups. CONCLUSION: Increased oxidative stress and alterations in lipid profile were observed among dogs with VL. However, no significant differences were detected between dogs at different stages of the disease. Therefore, changes in the TOS, PON-1 activity, and HDL and LDL levels in dogs at all stages of VL should be considered in the diagnosis of the disease and planning of the treatment.

Materials and methods. To this extent weaned 10 weeks of aged lambs were enrolled and randomly assigned into two groups based on treatment (group C, n=18 lambs treated with Cq) and placebo (group P, n=8 untreated control animals). Diagnosis was based on detection of trophozoit and/or cysts on fecal flotation. Cyst count per gram feces (days 0, 3, 7 and 10) was analyzed among groups. Results. During the trial, regarding the efficacy of Cq on days 3., 7., and 10. There was significant (p<0.01) reduction in cyst excretion; whereas evaluation of mean geometric cyst excretion revealed 100% reduction. Conclusions. There was a very high (100%) reduction in cyst excretion in the Cq treatment group compared to the positive untreated control group on days 3, 7 and 10, resulting in a significant (p<0.001) reduction, making Cq, safety, and thus highly effective treatment option of lambs with naturally occuring giardiasis.


RESUMEN Objetivo . El objetivo del presente estudio fue determinar la eficacia de la cloroquina, un medicamento contra la malaria, administrado a una dosis de 2.5 mg/kg, por vía oral, durante 5 días consecutivos, en Corderos Sakiz y Merino infectados naturalmente con Giardia duodenalis. Materiales y metodos. En esta medida destetados 10 semanas de edad fueron incluidos y asignados al azar en dos grupos sobre la base del tratamiento (grupo C, n = 18 corderos tratados con cloroquina) y placebo (grupo P, n = 8 animales de control no tratados). El diagnóstico se basa en la detección de trophozoit y/o quistes en la flotación fecal. Quiste recuento por gramo de heces (día 0, 3, 7 y 10) se analizó entre los grupos. Resultados. Respecto a la eficacia de la cloroquina en los días 3, 7 y 10 existió una reducción significativa (p<0.01) en la excreción de quistes; mientras que la evaluación de la media de la excreción de quistes reveló una reducción del 100%. Conclusiones. Durante el estudio hubo una reducción del 100% en la excreción de quistes en el grupo de tratamiento con cloroquina en comparación con el grupo control no tratado positivo en los días 3, 7 y 10, lo que resulta en una disminución significativa (p<0.001) por lo que la cloroquina razonablemente es una opción de tratamiento por el costo, seguridad, y por lo tanto muy eficaz de corderos infectados naturalmente con giardiasis.

RESUMO

BACKGROUND: The objective of this study was to determine the effect of ketoprofen on acute phase protein (APPs) concentrations in goats undergoing castration. A total of 16 clinically healthy, male and 12 months old goats were enrolled and each case received ketoprofen (group I) or control (group II) in a randomized fashion. Goats were sedated with Xylazine-HCl, afterwards ketoprofen (3 mg/kg) was injected via jugular vein in group I, whereas physiological saline solution was administered to group II. Goats were castrated by the Burdizzo method. Hematological parameters were determined with a blood cell counter and plasma fibrinogen (Fb), serum haptoglobin (Hp), serum amyloid A (SAA) and ceruloplasmin (Cp) concentrations were measured Millars technique, ELISA kit or p-phenylenediamine oxidase activity prior to castration and throughout the study on 0 to 96 h. RESULTS: There were no differences in pre-treatment serum Cp, SAA and Fb concentrations among the groups. Contrarily, there were significant differences in plasma Hp concentrations on 0 to 96 h onwards post-castration. There were no differences in WBC and PCV between groups. Cp, Fb, and SAA were almost constant or showed slight changes at various stages of the study with no significant differences between groups. CONCLUSIONS: The results revealed that, levels of Cp, Fb and SAA may not be affected by castration such as the confounding parameters similarly to stress. More investigations possessing different surgical or non-surgical castration techniques with larger number of goats and focusing on specific markers for stress are suggested for precise analysis.

RESUMO

Objective. The aim of this field trial was to investigate the relationships among subclinical laminitis, hematological, ruminal and faecal alterations. Materials and Methods. To this extent dairy cows presenting subclinical laminitis (n=11) and to those of other healthy cows without laminitis (n=10) were enrolled and assigned into two groups. All animals were receiving the same daily ration formulated to contain 47% cornsilage and 18% hay, mainly. Effects of subclinical laminitis challenges on measurements of feces, and blood samples, were investigated to determine which of these measurements may aid in the diagnosis. pH changes in ruminal fluid collected via rumenocentesis were measured. Besides the following parameters were also measured; blood pH, faecal pH and faecal scoring. Blinded investigators performed the sample collection. Results. No statistical differences between the groups were detected for blood gas values studied regarding pCO2, HCO3, BE, indeed mean that pO2 values decreased statistically (p<0.05) and faecal pH was significantly decreased (p<0.05) in cows with subclinical laminitis in contrast to healthy controls. Conclusions. pO2 values and faecal pH may be valuable as indirect indicators of subclinical laminitis in cattle.


Objetivo. El objetivo de esta prueba de campo fue investigar las relaciones entre la laminitis subclínicay alteraciones hematológicas, ruminales y fecales. Materiales y métodos. Las vacas lecheras que presentaron laminitis subclínica (n=11) y las vacas sanas sin laminitis (n=10) fueron reclutadas y asignadas en dos grupos. Todos los animales recibieron la misma ración diaria que contenía 47% de ensilaje de maíz y 18% de heno, principalmente. Los efectos de la laminitis subclínica sobre las mediciones de las heces y muestras de sangre, fueron investigados para determinar cuál de estas mediciones pueden ayudar en el diagnóstico. Se midieron los cambios de pH en el fluido ruminal recogido a través rumenocentesis. Además, también se midieron los siguientes parámetros; pH de la sangre, el pH fecal y la puntuación fecal. La toma de las muestras se realizó a doble ciego. Resultados. No se detectaron diferencias significativas entre los grupos para los valores de los gases sanguíneos estudiados en relación con la pCO2, HCO3, BE; lo que significa que los valores de pO2 disminuyeron estadísticamente (p<0.05) y que el pH fecal se redujo significativamente (p<0.05) en las vacas con laminitis subclínica; en contraste con los controles sanos. Conclusiones. Los valores de pO2 y pH fecal pueden ser valiosos como indicadores indirectos de la laminitis subclínica en el ganado.

RESUMO

Objectives. A. phagocytophilum, an obligate intracellular pathogen, is a well-known agent causing granulocytic infections in both animals and humans. The purpose of the present study was to describe clinical course and consequences of Canine Granulocyctic Anaplasmosis among dogs in Aydin province, Turkey with special reference to hematological alterations and possible interpretations of doxycycline+chloroquine dual therapy. Materials and methods. A controlled clinical trial was carried out on 14 dogs referred and diagnosed as Canine Granulocyctic Anaplasmosis within Snap 4dx test. Relevant haematological data were recorded before (day 0) and after treatment (day 30) in both groups. Group I (n=7) were adminestered doxycycline (10 mg/kg q 12 h via oral route for 14 days) and chloroquine (2.5 mg/kg q 12 h for 14 days) and group II (n=7) received only doxycycline (10 mg/kg q 12 h for 14 days via oral route) therapy. Results. Doxycycline treatment hasten resolution of clinical signs in all dogs in about 2 to 7 days. There was no statistically significant differences among hematological variances detected (p>0.05). Conclusions. It may suggest that in conjunction with doxycycline chloroquine may have helped to speed up relevant clinical signs of CGA.


Objetivo. A. phagocytophilum, un patógeno intracelular obligado, es un agente ampliamente conocido que causa infecciones granulocíticas tanto en animales como en humanos. El propósito del presente estudio fue describir la evolución clínica y las consecuencias de la Anaplasmosis Granulocítica Canina en perros de la provincia de Aydin, Turquía, con especial referencia a las alteraciones hematológicas y a las posibles interpretaciones de una terapia dual de doxicilina+cloroquina. Materiales y métodos. Se realizó un estudio clínico controlado en 14 perros remitidos y diagnosticados con Anaplasmosis Granulocítica Canina usando de una prueba Snap 4dx. Se registraron datos hematológicos pertinentes antes (día 0) y después del tratamiento (día 30) en ambos grupos. Al Grupo I (n=7) se le administró doxicilina (10 mg/kg q 12 h por vía oral durante 14 días) y cloroquina (2.5 mg/kg q 12 h durante 14 días), mientras que el Grupo II (n=7) recibió una terapia únicamente con doxicilina (10 mg/kg q 12 h por vía oral durante 14 días). Resultados. La doxicilina aceleró la resolución de los signos clínicos en todos los perros en un periodo de aproximadamente 2 a 7 días. No se detectaron diferencias estadísticas significativas entre las variaciones hematológicas (p>0.05). Conclusiones. Lo anterior puede sugerir que, conjuntamente con la doxicilina, la cloroquina puede haber ayudado a acelerar los signos clínicos pertinentes de la Anaplasmosis Granulocítica Canina (AGC).

RESUMO

Objective. In the present study alterations in trombocyte numbers and trombocyte indices were investigated in 51 dogs naturally infected with E. canis and/or A. phagocytophilum. Achieved results were compared to those of 20 healty dogs comprising control group. Materials and methods. Naturally occuring vector borne diseases were diagnosed by use of a canine point-of-care ELISA kit (Snap 4Dx, Idexx). Dogs were enrolled into 3 groups as follows; II. group involved A. phagocytophilum infected dogs (n=10), III. group (n=13) E. canis+ A. phagocytophilum co-infected, and IV. group (n=28) E. canis infected dogs. Healthy controls (n=20) were enrolled in group I. Results. Mean PLT counts were significantly decreased in II., III. and IV. groups (159.6±63.5, 142.3±44.3, 148.7±33.5, respectively) in comparison to control group (370.4±28.6) (p≤0.01). Mean PCT values in groups II., III. and IV. (0.1530±0.590, 0.1531±0.0441, 0.1450±0.314, respectively) were significantly decreased in contrast to control group (0.3695±0.0283) (p≤0.01). Between PLT and PCT values, statistically significant positive correlation (p≤0.01) (r=0.988, 0.990 and 0.981, respectively) was evident among groups II., III. and IV. Conclusions. Infected dogs showed significant alterations (p≤0.01) among mean PLT and PCT values and a positive correlation was evident between those 2 parameters (p≤0.01), whereas alterations on mean MPV and PDWc were not statistically significant. Finally it was suggested that according to the aforimentioned results, PLT and PCT values may be used as valuable parameters for diagnosis and probably for monitorization and prognosis in infected dogs with Ehrlichiosis and/or Anaplasmosis.


Objetivo. Comparar las alteraciones en el número de trombocitos y en los índices de trombocitos en perros infectados naturalmente con E. canis y A. phagocytophilum. Materiales y métodos. Los perros fueron distribuidos en cuatro grupos: Grupo I; perros sanos (n=20), Grupo II; perros infectados con A. phagocytophilum (n=10), Grupo III; perros infectados con E. canis + A. phagocytophilum (n=13) y grupo IV; perros infectados con E. Canis (n=28). Resultados. Los recuentos de PLT se redujeron significativamente (p≤0.01) en los grupos II, III y IV (159.6±63.5, 142.3±44.3, 148.7±33.5, respectivamente) en comparación con el grupo control (370.4±28.6). La media de los valores de PCT en los grupos II, III y IV fue de 0.1530±0.590, 0.1531±0.0441 y 0.1450±0.314 respectivamente, cuyas reducciones fueron significativas (p≤0.01) en contraste con el grupo control (0.3695±0.0283). Entre los valores de PLT y el PCT la correlación fue positiva (r =0.988) y significativa (p≤0.01), 0.990 y 0.981, respectivamente, entre los grupos II, III y IV. Conclusiones. Los perros infectados mostraron alteraciones significativas (p≤0.01) entre PLT y los valores del PCT, así como una correlación positiva entre esos dos parámetros (p≤0.01), mientras que las alteraciones de MPV y PDWc no fueron significativas. Se sugiere que de acuerdo con los resultados obtenidos, los valores de PLT y el PCT se pueden utilizar como parámetros valiosos para el diagnóstico y probablemente, para el monitoreo y el pronóstico en perros infectados con la Ehrlichiosis o la Anaplasmosis.

RESUMO

Oxidative stress was defined as corruption of balance between oxidant-antioxidant states in favor of oxidants. In this study, it was aimed to determine oxidative stress in naturally infected dogs with Babesia vogeli. The 8-hydroxy-2'-deoxyguanosine (8-OHdG), nitric oxide (NO) and total antioxidant capacity (TAC) levels in the sera were analyzed by ELISA. 8-OHdG levels increased in B. vogeli infected dogs compared to control group (P<0.05). Also, NO levels increased while TOC levels decreased in B. vogeli infected dogs but these variations were not found as statistically important (P>0.05).

RESUMO

Objective. Assess the spatial distribution of seroprevalence of infection with or exposure to 4 vector-borne pathogens Ehrlichia canis, Anaplasma phagocytophilum, Borrelia burgdorferi and Dirofilaria immitis, across the coastal states of the Aegean region with special reference to clinical signs and haematological variances related to disease condition. Materials and methods. A convenience sample, targeting blood from at least 10 pet dogs from Izmir, Aydin, Denizli, Mugla and Manisa cities involved was evaluated using a canine point-of-care ELISA kit. Results. Out of 307 dogs tested the overall seroprevalence was highest for E. canis (24.42%), followed by E. canis + A. phagocytophilum co-infection (10.42%), A. phagocytophilum (7.49%) and D. immitis (2.28%). Only 2 cases were seropositive to B. burgdorferi albeit 10 dogs were co-infected with more than 2 agents. For both dogs infected with E. canis and co-infected with E. canis and A. phagocytophilum, anemia, thrombocytopenia and leukocytosis, were more commonly detected, whereas thrombocytopenia and leukocytosis were significant finding in dogs infected with A. phagocytophilum or D. immitis, respectively. Variance analysis showed significant differences for mean RBC, Hb, PCV and PLT values (p<0.01) among control group and other groups. Conclusions. Seropositivity for vector-borne pathogens other than B. burgdorferi, is moderately to widely distributed in dogs residing in the Aegean region in Turkey.

Evaluar la distribución espacial de la seroprevalencia de la infección de 4 agentes patógenos de transmisión por vectores Ehrlichia canis, Anaplasma phagocytophilum, Borrelia burgdorferi y Dirofilaria immitis, en los estados costeros de la región del Egeo con especial referencia a los signos clínicos y las variaciones hematológicas relacionadas con la enfermedad. Materiales y métodos. Se tomaron por conveniencia muestras de sangre de al menos 10 perros en las ciudades Izmir, Aydin, Denizli, Mugla y Manisa. Para la evaluación de las muestras se utilizó un kit de ELISA para la detencción de anticuerpos de las enfermedades del estudio. Resultados. De los 307 perros muestreados, la seroprevalencia más alta fue para E. canis (24.42%), seguido por la coinfección entre E. canis + A. phagocytophilum (10.42%), A. phagocytophilum (7.49%) y D. immitis (2.28%). Sólo 2 casos fueron seropositivos para B. burgdorferi aunque 10 perros fueron coinfectados con más de 2 agentes. En ambos perros infectados con E. canis y coinfectados con E. canis y A. phagocytophilum, se detectó comúnmente anemia, trombocitopenia y leucocitosis, mientras que la trombocitopenia y leucocitosis fueron significativos en perros infectados con A. phagocytophilum o D. immitis , respectivamente. El análisis de varianza mostró diferencias significativas para los promedios de RBC, hemoglobina, hematocrito y valores PLT (p<0.01) entre el grupo control y los otros grupos. Conclusiones. La seropositividad transmitida por vectores patógenos distintos de B. burgdorferi, fue moderada y ampliamente distribuida en los perros que residen en la región del Egeo en Turquía.

RESUMO

Objetive. The purposes of this study were to determine whether secnidazole administered at a single dose of 10 mg/kg, orally, lessens or eliminates Giardia cyst shedding, and to validate the benefit of secnidazole treatment on clinical signs and faecal consistency in lambs naturally infected with Giardia duodenalis. Materials and methods. To this extent weaned 12 weeks of age lambs were selected and randomly assigned into two groups based on placebo (group C, n=7 untreated control group) or treatment (group S, n=10 lambs treated with a single dose of secnidazole at 10 mg/kg). Results. On days 0 and 10, before and after treatment, respectively, reduction in cyst excretion was determined. The faecal consistency and general health were recorded at each sampling day. Conclusions. During the study there was a high (99.98%) reduction in cyst excretion in the secnidazol treatment group compared to the positive control group on day 10, resulting in a significant (p<0.001) reduction, making secnidazole highly effective treatment option.


Objetivo. El objetivo de este estudio fue determinar si la administración oral de una dosis única de secnidazol de 10mh/kg reduce o elimina la presencia de quistes de Giardia y validar el beneficio del tratamiento con secnidazol en los signos clínicos y la consistencia fecal de corderos infectados naturalmente con Giardia duodenalis. Materiales y métodos. Se seleccionaron corderos destetados de 12 semanas de edad que fueron asignados al azar a dos grupos con base a placebo (grupo C, n=7, grupo de control sin tratar) o tratamiento (grupo S, n=10 corderos con tratamiento de dosis única de secnidazol de 10 mg/kg). Resultados. En los días 0 y 10, antes y después del tratamiento, respectivamente, se determinó una merma en la excreción de quistes. La consistencia de la materia fecal y el estado general de salud fue registrado en cada muestreo diario. Conclusiones. Durante el estudio hubo una alta reducción en la excreción de quistes (99.98%) en el grupo tratado con secnidazol comparado con el grupo control positivo en el día 10, resultando en una disminución significativa (p<0.001), haciendo del tratamiento con secnizadol una opción altamente efectiva.
