Interpretation of coagulation tendency contributing to thrombosis in vector-borne diseases (ehrlichiosis, anaplasmosis, leishmaniosis, and dirofilariasis) among dogs

Background: Vector-borne infectious and zoonotic diseases are an important health problem that directly affects human and animal health negatively. Results through evaluation of coagulation disorders among vector-borne diseases should be of beneficial for both human and dogs studies. According to the present authors knowledge reports regarding changes in platelet (PLT) count, prothrombin time (PT), activated partial thromboplastin time (APTT), fibrinogen (FIB) and D-dimer levels in dogs naturally infected with one or more vector-borne pathogens are lacking. Therefore, the present study was aimed to detecting those parameters for relation between diagnosis and prognosis of vector-borne diseases among dogs. Materials, Methods & Results: The material of this study was 46 dogs (36 were naturally infected with vector-borne diseases and 10 were healthy) from different breed, age and of both sexes. Venous blood samples were obtained to detect PLT counts, antibodies of ehrlichiosis, anaplasmosis, borreliosis, leishmaniosis and antigens of Dirofilaria immitis. The diagnosis of vector-borne diseases was performed by using a commercial ELISA assay kits. PLT count was performed with an automated blood cell counter analyser. In addition, PT, APTT and FIB concentrations were measured using a microcoagulometer. D-dimer concentrations were determined using fluorescence immunoassay rapid quantitave test analyser. Subgroups were formed according to the number of cases and the distribution of vector-borne agent. Statistically significant decreased PLT count was found in dogs mono infected with ehrlichiosis compared to healthy dogs (P < 0.001). Changes in mean PT value in the studied animals did not show statistically significant differences among the groups (P > 0.05). APTT values in the ehrlichiosis mono infection group were significantly higher than that of the healthy control (P < 0.01). A significant increase in FIB levels were detected […](AU)

Prevalence and molecular characterization of Giardia duodenalis in calves in Turkey

Background: Giardia duodenalis (G. duodenalis) is an ubiquitous, flagellated intestinal protozoan with major public health significance worldwide. Limited data are available on the epidemiology of G. duodenalis in dairy cattle from Turkey. Determining the zoonotic potential of the Giardia infection requires molecular characterization. The aim of the present study was to investigate the prevalence and to molecularly characterize G. duodenalis in calves less than three months of age in Aydin, Aegean region of Turkey. Materials, Methods & Results: The study was conducted on different dairy farms in the south-western part of the Turkey, Aegean Region, Aydin. A total of 198 Holstein Friesian calves less than three months of age, of both sexes were enrolled into the study. Faecal samples from each calf were collected manually from the rectum using a disposable latex glove. The consistency of collected samples was recorded as diarrhoeic or non-diarrhoeic. Diagnosis of G. duodenalis infection was made microscopically by detection of cysts in the faecal samples. One hundred and sixteen (58.5%) of the 198 faecal samples were diarrheic. Giardia cysts were found in 27 (23.28%) of the diarrheic samples and in 8 (9.76%) of nondiarrheic samples (P < 0.05). The overall prevalence of giardiosis in calves was determined as 17.67%. The prevalence of Giardia genotypes was identified by DNA sequence analysis of the beta-giardin gene for every PCR positive sample. The beta-giardin nested PCR assay was revealed assemblage A and sub-genotype A3 was detected in all of 35 samples (100%). Discussion: The highest prevalence of Giardia infection in calves is reported at the age between 1 and 6 months, and the prevalence shows decreased rate from the age of 6 months. The present study was conducted in Aydin, a province of south-western Turkey in the Aegean Region, and the overall prevalence from a total of 198 dairy calves was 17.67%. […](AU)

Florfenicol Therapy During Natural Mannheimia haemolytica Infection in Sakiz Sheep

Background: Bronchopneumonia caused by Mannheimia haemolytica affects sheep of all ages worldwide and may be devastating especially in young animals undergone recent stress (i.e. transportation, weaning, mixing with animals from different farms. It is a common cause of morbidity and mortality in lambs and kids, especially in those that have not received adequate colostrum or in which passive colostral immunity is waning. Yearly herd losses costing millions of dollars have led to research focused on theurapeutic trials and vaccine production because of various strains isolated demonstrating the continuing economic importance of Mannheimia haemolytica infection. A field trial was performed under commercial sheep farm located in Western Turkey, Aydin in an attempt to investigate the efficacy of an injectable formulation of florfenicol against naturally occuring Mannheimia haemolytica. Materials, Methods & Results: A total of 27 Sakiz breed lambs at the age of 36–60 days old, of both sexes, with naturally occuring M. haemolytica infection were included in the present study. Prior to allocation into groups, a detailed clinical examination carried out in all the lambs, revealed a variety of abnormal findings: coughing, presence of nasal and ophthalmic discharge increased respiratory rate and rectal temperature and abnormal sounds at lung auscultation. A total of 27 samples taken from transtracheal aspiration bronchoalveolar fluid in the Sakiz breed lambs were taken into sterile containers in an attemp to perf orm isolation and identification of Mannheimia haemolytica . The antibiotic susceptibility tests for Mannheimia haemolytica strains isolated from transtracheal aspiration bronchoalveolar fluid were carried out by disc diffusion as described previously. [...]

A flock level analysis of an outbreak of natural border disease in Sakiz ewes and their progeny

Background: Pestiviruses cause economically important diseases in domestic ruminants worldwide. Border Disease is a congenital viral infection of sheep, caused by a pestivirus, and is first reported in the Border region of Wales and England. The BDV has worldwide distribution in sheep with different prevalences among countries. Vertical transmission is an important route in the epidemiology of this virus. Infection of fetuses may cause birth of persistently infected lambs, that are viremic, antibody negative, and are excreting virus. The disease is characterized by abortion, barren ewes, stillbirth and persistently infected weak lambs showing neurological and dermatological signs. The economic importance of the disease is related to reproductive failure, abortions and significantly low survival rate of affected lambs. In the present study the aim was to describe clinical, hematological and serological aspects of natural Border disease virus (BDV) infection in a sheep flock in Cine, Aydin. Besides we sought to elucidate the relationship between natural (active infection) and persistent BDV disease and the serum concentration of haptoglobin (Hp) and serum amyloid A (SAA) in infected sheep Materials, Methods & Results: Field observations were carried out in a sheep flock comprising 327 sheep with a history of an outbreak abortion in Cine town in Aydin, Turkey. Twenty-five out of 327 sheep in the flock was monitorized by blood sampling. The animals were selected among aborted ones, at least once, into two weeks preceeding period or with a history of weak lambing. BDV antigen (persistent infection) was detected in 8 out of 25 sheep (32%) while antiviral antibodies (active infection) were detected in 18 animals tested (68%). The disease was mainly characterized by abortions, stillbirth/weak lamb and abnormal brown/black fleece pigmentation, which occurred in an epidemic form. Twenty five sheep were related to disease condition as detected serologically, and the ratio of the number affected to number at risk being was 17:8. The culling rate was 50% of the affected animals. Most of the affected animals were second lambing sheep (5/25, 20%). Hematological variables did not reveal statistical difference whereas serum concentrations of Hp (P < 0.05) and SAA (P < 0.01) were significantly higher in naturally infected sheep in contrast to persistently infected sheep with BDV. Discussion: Clinical signs and detailed laboratory analysis related to natural Border disease outbreak have never been reported in Turkey, although previous epidemiological studies had shown that Border disease virus infection is relatively common in some parts of Turkey in sheep flocks and persistent Border disease virus infection had been described in apparently healthy sheep in Turkey. In the present study the disease was mainly characterized by abortions, stillbirth/weak lamb and abnormal brown/black fleece pigmentation, which occurred in an epidemic form. Besides bronchopneumonia, enteritis and conjunctivitis were detected in a limited population. Neurological signs were only observed in 2 animals. Besides persistent infection was detected in 32% of sheep enrolled. An acute phase reaction involving Hp and SAA has been identified in the present study. These results indicate that the monitoring of selected acute phase proteins may increase the diagnostic information available as a result of their analyses in naturally infected sheep and persistently infected sheep with BDV.

One hundred and sixteen (58.5%) of the 198 faecal samples were diarrheic. Giardia cysts were found in 27 (23.28%) of the diarrheic samples and in 8 (9.76%) of nondiarrheic samples (P 0.05). The overall prevalence of giardiosis in calves was determined as 17.67%. The prevalence of Giardia genotypes was identified by DNA
