Evaluation of different supportive treatments during packed cell volume replacement in calves naturally infected with tick fever agents.

This study evaluated the effect of different supportive treatments on PCV replacement of dairy calves naturally infected with tick fever (TF) agents, and treated with diminazene and enrofloxacin. Five products were tested as supportive treatments in four experiments. In these experiments, we used Girolando female calves (Gyr × Holstein, genetic ratio of 15/16 and 31/32 Holstein) four to six months old, raised in pasture, naturally infected with TF agents, and infested with R. microplus. Supportive treatment was administered once on day 0 of the study concurrently with specific treatment targeting TF agents. The animals were observed on days 0, 3, and 7. Oral or intravenous administration of a vitamin complex and mineral salts enhanced the increase in PCV and biochemical analytes present in the serum of calves naturally infected with TF agents. No positive effect on PCV values was observed with the administration of (1) invigorating tonic: calcium, casein-peptides and vitamin B12, (2) iron-based stimulant tonic and (3) metabolic tonic: vitamin A, vitamin D, and a fraction of polyunsaturated fatty acids. Supplementation by injection with Type III iron resulted in increased hemoglobin and PCV in treated animals. However, these results did not occur with iron citrate. Therefore, more studies with Type III iron need to be performed. Supportive treatment conferred no advantage in animals with no history of reduced PCV.

Therapeutic efficacy of enrofloxacin in treatment of Francisella orientalis infections in juvenile Nile tilapia (Oreochromis niloticus L.).

Outbreaks of infections by Francisella orientalis represent one of the main obstacles to Nile tilapia (Oreochromis niloticus L.) farming. It is responsible for acute mortality in fingerlings and juveniles. The main control measure available is oral antibiotic therapy. This study compared the therapeutic efficacy of the antibiotics enrofloxacin and oxytetracycline, the most commonly used antimicrobial, against francisellosis in juvenile Nile tilapia (O. niloticus). Fish were challenged with a virulent isolate of F. orientalis and treated with medicated feed containing one of two doses of oxytetracycline (100 or 300 mg/kg of live weight (LW)) or 10 mg/kg of LW of enrofloxacin. The positive and negative control groups received feed without antibiotics; the negative control group was unchallenged. The results showed that enrofloxacin at a dose of 10 mg/kg of LW is effective against francisellosis in juvenile Nile tilapia (O. niloticus). Treatment with oxytetracycline did not eliminate the pathogen from the infected host, and the surviving fish became carriers. Enrofloxacin was able to cure the fish of infection with F. orientalis. This study suggests that enrofloxacin is a better option for treating francisellosis in Nile tilapia (O. niloticus L.). It controls mortality and avoids the carrier state in the fish, thus reducing the possibility of recurrence in the affected batches.

Efficacy of antimicrobial therapy in association with vaccination on the bacteriological cure of subclinical mastitis caused by Staphylococcus aureus in lactating cows / Eficácia da terapia antimicrobiana associada à vacinação na cura bacteriológica de mastite subclínica causada por Staphylococcus aureus em vacas em lactação

The objective of this study was to evaluate the efficacy of the antibiotic therapy associated with vaccination on the microbiological cure rate of subclinical mastitis caused by Staphylococcus aureus in lactating dairy cows. A total of five herds, from which 72 cows (120 mammary quarters - MQ) were diagnosed with S. aureus subclinical mastitis, were included in this study. Cows were randomly allocated to one of three treatment groups: a) Control (no treatment); b) ATB (antibiotic therapy); and c) ATB+VAC (antibiotic therapy plus vaccination against S. aureus). Intramammary treatment consisted of twice-daily infusion of ampicillin 75mg + cloxacillin 200mg, for 5 days. Parenteral treatment was done by injection of a single dose (7.5mg/kg) of enrofloxacin, on the first day of the treatment protocol. Vaccinated cows received three doses of a commercial vaccine 14 days before treatment (d-14), on the first day of treatment protocol (d1), and 14 days after the treatment protocol (d+14). Non-treated cows had a lower cure rate (0.06) than cows treated with ATB (0.84) and ATB+VAC (0.85). No difference in cure rate was observed between cows treated with ATB and ATB+VAC. On the other hand, vaccinated cows had lower somatic cell count (SCC) after 28 days of the treatment protocols (4.76 log10) than non-treated cows (5.37 log10). In conclusion, treatment with intramammary ampicillin and cloxacillin, associated with intramuscular enrofloxacin presented a high cure rate for SCM caused by S. aureus during lactation. The use of vaccination against S. aureus in association with antibiotic therapy did not increase the cure rate of MQ during lactation, but it was effective in reducing the SCC when compared to non-treated MQ. Although to ensure that the decrease of the SCC in ATB+VAC group was associated with the vaccination, the study should have included an additional group of only vaccinated cows, without antimicrobial therapy, with was not done in the present study, and therefore is one of the limitations of the experimental protocol used.

O objetivo deste estudo foi avaliar a eficácia da antibioticoterapia associada à vacinação sobre a taxa de cura microbiológica de mastite subclínica causada por Staphylococcus aureus em vacas leiteiras em lactação. Foram selecionados 5 rebanhos, dos quais 72 vacas (120 quartos mamários, QM) foram diagnosticadas com mastite subclínica por S. aureus e foram alocadas aleatoriamente em um de três grupos de tratamento: a) Controle (sem tratamento); b) ATB (antibioticoterapia); e c) ATB+VAC (antibioticoterapia mais vacinação contra S. aureus). O tratamento intramamário consistiu em infusão de ampicilina 75 mg + cloxacilina 200 mg duas vezes ao dia, durante 5 dias. O tratamento parenteral foi feito por injeção de uma dose única (7,5 mg/kg) de enrofloxacina, no primeiro dia do protocolo de tratamento. As vacas vacinadas receberam três doses de uma vacina comercial, 14 dias antes do tratamento (d-14), no primeiro dia do protocolo de tratamento (d1) e 14 dias após o protocolo de tratamento (d+14). A taxa de cura das vacas não tratadas foi menor (0,06) do que das vacas tratadas com ATB (0,84) e ATB+VAC (0,85). Não foi observada diferença de taxa de cura entre vacas tratadas com ATB e ATB+VAC. Por outro lado, as vacas vacinadas apresentaram menor a contagem de células somáticas (CCS) após 28 dias de tratamento (4,76 log10) do que em vacas não tratadas (5,37 log10). Em conclusão, o tratamento com ampicilina e cloxacilina intramamária, associados à enrofloxacina intramuscular, apresentou alta taxa de cura para MSC causada por S. aureus durante a lactação. A utilização da vacinação contra S. aureus associada à antibioticoterapia não aumentou a taxa de cura dos QM durante a lactação, mas foi eficaz na redução do CCS quando comparada à QM não tratados. Entretanto, para ter certeza que a diminuição da CCS no grupo ATB+VAC estivesse associada à vacinação, o estudo deveria ter incluído um grupo adicional de apenas vacas vacinadas, sem terapia antimicrobiana, o que não foi feito no presente estudo e, portanto, é um das limitações do protocolo experimental utilizado.

Successful treatment of recurrent subclinical mastitis in cows caused by enrofloxacin resistant bacteria by means of the sequential intramammary infusion of enrofloxacin HCl-2H2O and ceftiofur HCl: a clinical trial.

BACKGROUND: Recurrent subclinical mastitis (RScM) due to resistant bacteria has low clinical and bacteriological cure rates, often requiring the culling of cows. The sequential intra-mammary administration of enrofloxacin hydrochloride-dihydrate (enro-C) followed by ceftiofur HCl may be useful for treating these cases. OBJECTIVES: This study assessed the bacteriological and clinical cure-efficacies of the sequentially intramammary administration of enro-C, followed by ceftiofur HCl to treat RScM in Holstein/Friesian cows. METHODS: This trial was conducted in a herd with a high prevalence of RScM, and 20 Holstein/Friesian cows were included: 45% suffering subclinical mastitis and 38.9% of the mammary quarters affected. Twenty-nine bacterial isolates in vitro resistant to enro-C were obtained (coagulase-negative Staphylococcus spp, 55.2%; Staphylococcus aureus, 27.6%; Escherichia coli, 6.9%; Streptococcus uberis, 6.9%; Corynebacterium bovis, 3.4%). Polymerase chain reaction-isolated the following genes linked to enro-C resistance: chromosomal (gyrA) and plasmid (aac(6')-lb-cr). The treatments were as follows: twice-daily intramammary infusions of enro-C (300 mg/10 mL) for 5 days. Cows clinically considered treatment failures were also treated with intramammary ceftiofur (125 mg/10 mL, twice daily for 5 days. The clinical and bacteriological cure rates were carried out when completing each treatment phase and at 14 and 21 days, aided by a California mastitis test, somatic cell count, and failure to identify the initially causative bacteria. RESULTS: Enro-C achieved 65% clinical and bacteriological cure rates, and 100% cure rates were obtained after the rescue treatment with ceftiofur HCl. CONCLUSIONS: Outstanding clinical and bacteriological cure rates in cows affected by RScM were achieved with the consecutive intramammary infusions of enro-C, followed by ceftiofur HCl.

Delayed reduction of Anaplasma marginale parasitemia and packed cell volume normalization despite prolonged enrofloxacin treatment of cattle co-infected with Trypanosoma vivax.

Although co-infections of Trypanosoma vivax, Anaplasma spp., and Babesia spp. have been reported, knowledge gaps remain that need to be addressed. The present study evaluated the efficacy of enrofloxacin (7.5 mg/kg) against A. marginale in naturally infected cattle and cattle experimentally co-infected with T. vivax by observation of the variation in A. marginale parasitemia and packed cell volume (PCV) for 39 days. Bovines were distributed into two groups, each with six calves: T01 = animals immunosuppressed with dexamethasone and with latent anaplasmosis; T02 = animals immunosuppressed with dexamethasone, with latent anaplasmosis and experimentally co-infected with T. vivax on day 0 (D0). Animals of both groups were immunosuppressed with dexamethasone and received enrofloxacin (7.5 mg/kg) whenever mean values of parasitemia for A. marginale were ≥ 5% per group. Cattle of group T02 were also treated with isometamidium chloride (0.5 mg/kg) on D25. On D17 and D22 to D28 of the study, there was a higher (P ≤ 0.05) A. marginale parasitemia in animals of T02 than in those of T01. Animals of T01 required one enrofloxacin treatment to decrease A. marginale parasitemia, while those from T02 needed five treatments. From D5 to D37 of study, the mean values of PCV for calves from T02 were lower (P ≤ 0.05) than that for calves from T01. In conclusion, bovines co-infected T. vivax needed four more treatments with enrofloxacin to reduce A. marginale parasitemia and keep PCV values within reference standards.

Penfigoide bolhoso em cão / Bullous pemphigoid in a dog

Background: In dogs, bullous pemphigoid (BP) is a subepithelial autoimmune disease, a rare dermatopathy in the clinicalroutine. BP is characterized by formation of vesicles and subepidermal blisters that result from dissolution of the dermalepithelial junction. Clinical signs of BP usually include severe dermatological alterations with a variable prognosis. Theaim of this work is to report a case of BP in a dog to contribute information for diagnosis, and to present clinical andpathological aspects that emerge during development of BP.Case: An adult male mongrel dog exhibited hyperemic, exudative, crusty lesions on the lip commissure and periocularareas. Results from laboratory tests were normal. Results from parasitological and mycological tests on skin scrapingswere negative. Imprint cytology of the crusts revealed presence of gram-positive cocci bacteria. In the histopathologicalanalysis of punch biopsy material, the epidermis was detached from the dermis, leading to formation of vesicles. Therewere inflammatory infiltrates containing neutrophils, eosinophils, and high amounts of fibrin, and areas of multifocalorthokeratotic hyperkeratosis. Multifocal infiltrates containing lymphocytes, histiocytes, and plasma cells were observedon the superficial portions of the dermis, which indicated a diagnosis of BP. After the definitive clinical diagnosis, theanimal was treated with enrofloxacin (Baytril Flavour®; 5 mg/kg once a day for 10 days), and prednisolone (Prediderm®;2 mg/kg once a day until further instructions). On the follow-up visit, 15 days later, the clinical picture had improved, andthe lesions had decreased. Continuity of the treatment was prescribed, along with a gradual decrease in the corticoid dose.The dose of prednisolone was initially reduced to 1 mg/kg once a day, and later to 0.5 mg/kg until improvement of theclinical status of the patient. Remission of the lesions was observed 13 weeks later...(AU)

Granuloma lepróide canino em Mineiros região Centro-Oeste do Brasil / Canine leproid granuloma in mineiros city Mid-West region of Brazil

Background: Among the bacterial dermopathy the canine leproid granuloma (CLG) is a nodular pyogranulomatous disorder that affects the skin or subcutaneous tissue mainly in the dorsal face of ear pinna, head, and extremity of memberscaused by Mycobacterium spp. The pathogenicity is still not well clarified regarding the causative agent, which has notyet been completely typified, but phylogenetically, it is related to Mycobacterium tilburgii, M. simiae, and M. genavense,in Brazil, by the species M. murphy. The objective of this study is to report a case of canine leproid granuloma, throughcytology and histopathology, and present the therapeutic procedures until the regression of cutaneous lesion.Case: A 5-year-old Boxer breed, intac male weighing 32 kg, was assisted at the Veterinary Clinic of UNIFIMES, in MineirosCity, Mid-West Region of Brazil, GO, Brazil. The animal had 4 nodules in the ears with evolution of 30 days, with nopruritus and without previous treatment. During the physical exam, the animal had normal physiological parameters. Thecutaneous lesions were characterised by papules and alopecic nodules of firm to fibroelastic consistency, with progressiveincrease, located in the convex face of the ears. The fine needle aspiration puncture technique (FNAP) and histopathologyfor a definitive diagnosis was used, allowing the differentiation between inflammatory processes, infectious and neoplastic. Furthermore, blood was collected for hemogram and biochemical analysis for the assessment of renal and hepaticfunctions. In cytology, the stained blades by the Diff-quick stain in the microscopic exam had elevated cellularity, withseveral macrophages, and bacilliform structures in the negative image. Staining was also conducted....(AU)

Profiles of Staphyloccocus aureus isolated from goat persistent mastitis before and after treatment with enrofloxacin.

BACKGROUND: Staphylococcus aureus is one of the main causative agents of mastitis in small ruminants. Antimicrobial use is the major treatment, but there are many flaws linked to resistance, tolerance or persistence. This study aimed to verify changes in resistance, virulence and clonal profiles of S. aureus isolated from persistent mastitis goat milk before and after enrofloxacin treatment. RESULTS: MIC increased to at least one antimicrobial in S. aureus isolates after enrofloxacin treatment compared to before. The most detected resistance genes before and after treatment were tetK, tetM, and blaZ, with more resistance genes detected after enrofloxacin treatment (p < 0.05). Occasional variations in efflux system gene detection were observed before and after treatment. Nine virulence genes (hla, fnbA, fnbB, eta, etb, sea, sec, seh, and sej) were detected at both times, and between these, the hla and eta genes were detected more in isolates after treatment. All isolates of S. aureus belonged to the same sequence type (ST) 133, except for two S. aureus isolates prior to enrofloxacin treatment which were classified as ST5 and the other as a new one, ST4966. Isolates of S. aureus 4, 8, and 100 from before and after treatment had identical pulse types, while others obtained from other animals before and after treatment were classified into distinct pulse types. CONCLUSION: There were occasional changes in the studied profiles of S. aureus isolated before and after treatment of animals with enrofloxacin, which may have contributed to the permanence of bacteria in the mammary gland, even when using traditional treatment, resulting in persistent mastitis.

Pancreatic multifocal necrosis in female cat: case report / Necrose multifocal pancreática em gata: relato de caso

Pancreatitis is the inflammatory process of the exocrine pancreas, with necrosis and fibrosis as the main structural alterations. Felines may present the acute and chronic forms of the disease. A domestic, female, undefined feline (srd) was taken to a Private Veterinary Hospital in the city of Guarulhos, state of São Paulo. The animal had signs of apathy, prostration, inappetence, anorexia and bilateral exposure of the third eyelid. After the physical examination, blood was collected for haematological and biochemical exams. Abdominal ultrasonography was also requested, where reverberation was detected in the region of the intestinal loop, hyperechogenicity of the duodenal wall and reverberation of the pancreas. According to the results of the blood tests and ultrasonographic findings, we opted for exploratory laparotomy. During the surgical procedure a pancreatic fragment was collected for histopathological analysis. The histopathologic result was compatible with moderate multifocal pancreatic necrosis. Therefore, was instituted antibiotic therapy with Enrofloxacin (5 mg / kg, BID, IM for 5 days), analgesia with Tramadol Hydrochloride (2 mg/kg, BID, IV for 4 days) and Betamethasone (0.3 mg/kg, SID, IV). After the beginning of treatment with corticosteroid, the animal began to improve and eat. Many cases are diagnosed as acute or chronic pancreatitis only due to changes in pancreatic enzymes and ultrasonographic changes in the pancreas, using histopathological examination, which is a more instructive technique. It is very likely that pancreatic necrosis is not a pathology of low incidence, but rather poorly diagnosed due to difficulties in performing a biopsy.(AU)

A pancreatite é o processo inflamatório do pâncreas exócrino, tendo a necrose e a fibrose como principais alterações estruturais. Felinos podem apresentar as formas aguda e crônica da doença. Foi levado a um Hospital Veterinário Particular na cidade de Guarulhos, estado de São Paulo, um felino doméstico, fêmea, sem raça definida (srd). O animal apresentava sinais de apatia, prostração, inapetência, anorexia e exposição bilateral da terceira pálpebra. Após o exame físico, foi feita coleta de sangue para realização de exames hematológicos e bioquímicos. Foram solicitados ainda ultrassonografia abdominal, onde foi detectada reverberação em região de alça intestinal, hiperecogenicidade de parede duodenal e reverberação de pâncreas. De acordo com os resultados dos exames de sangue e os achados ultrassonográficos, optou-se pela laparotomia exploratória. Durante o procedimento cirúrgico foi coletado um fragmento pancreático para análise histopatológica. O resultado do histopatológico foi compatível com necrose pancreática multifocal moderada. Sendo assim, foi instituída antibióticoterapia com Enrofloxacina (5 mg/kg, BID, IM, durante 5 dias), analgesia com Cloridrato de Tramadol (2 mg/kg, BID, IV, durante 4 dias) e Betametasona (0,3 mg/kg, SID, IV). Após o início do tratamento com corticosteróide, o animal começou a apresentar melhora, voltando a se alimentar. Muitos casos são diagnosticados como pancreatite aguda ou crônica apenas por conta das alterações em enzimas pancreáticas e alterações ultrassonográficas em pâncreas, lançando mão do exame histopatológico, que é uma técnica mais elucidativa. Muito provável que a necrose pancreática não seja uma patologia de baixa incidência, e sim, pouco diagnosticada, devido às dificuldades em se realizar biópsia.(AU)
