Histophilus somni is a Gram-negative bacterium that is associated with a disease complex (termed histophilosis) that can produce several clinical syndromes predominantly in cattle, but also in sheep. Histophilosis is well described in North America, Canada, and in some European countries. In Brazil, histophilosis has been described in cattle with respiratory, reproductive, and systemic disease, with only one case described in sheep. This report describes the occurrence of Histophilus somni-associated disease in sheep from Southern Brazil. Eight sheep with different clinical manifestations from five farms were investigated by a combination of pathological and molecular diagnostic methods to identify additional cases of histophilosis in sheep from Brazil. The principal pathological lesions were thrombotic meningoencephalitis, fibrinous bronchopneumonia, pulmonary abscesses, and necrotizing myocarditis. The main clinical syndromes associated with H. somni were thrombotic meningoencephalitis (n = 4), septicemia (n = 4), bronchopneumonia (n = 4), and myocarditis (n = 3). H. somni DNA was amplified from multiple tissues of all sheep with clinical syndromes of histophilosis; sequencing confirmed the PCR results. Further, PCR assays to detect Pasteurella multocida and Mannheimia haemolytica were negative. These findings confirmed the participation of H. somni in the clinical syndromes investigated during this study, and adds to the previous report of histophilosis in sheep from Brazil.

In order to determine auscultatory and electrocardiographic characteristics of Crioulo horses, one hundred animals ranging between one and twenty-six years of age (21 stallions, nine geldings, 27 pregnant mares e 43 not pregnant mares) were evaluated. The cardiac auscultation was performed during the clinical examination of the cardiovascular system, evaluating frequency, rate, normal and abnormal heart sounds (heart murmurs). The electrocardiographic examination followed the bipolar base-apex derivative system with animals at rest, by using an ECG-PC TEB equipment. The cardiac frequency, heart rate, morphology, duration, wave and complex amplitudes and interval durations were determined. The results were submitted to ANOVA and Tukey tests with an error probability of 5%. The cardiac auscultation revealed presence of functional systolic and diastolic murmur (10.00%) and systolic murmur compatible with tricuspid regurgitation besides normal heart sounds S 1 (100.0%), S 2 (100.0%), S 3 (19.0%) and S 4 (34.0%). The cardiac frequency obtained the average of 43.64 bpm, observing significative differences in relation to sexual and age factors and training level. The sinus rhythm was the most frequent (57.00%), followed by sinus tachycardia (38.00%) and sinus arrhythmia (5.00%), being observed rhythm disturbances in 16% of tracings. The P and T waves were observed more frequently in their forms P bifida positive (95.00%) and biphasic T (91.00%), being variable at tracing. There were also observed Q waves in 12.00% of the tracings. Thus, it was concluded that the auscultatory characteristics of Crioulo horses are according to the described in the literature for the species and the sexual factor, category, age factor and training level can influence some electrocardiographic parameters. dos 100 animais (21 garanhões, nove machos castrados, 27 fêmeas prenhes e 43 fêmeas vazias) com idades entre um e 26 anos. A auscultação cardíaca foi realizada junto ao exame clínico do sistema cardiovascular, avaliando-se frequência, ritmo e sons cardíacos normais e anormais (sopros). O exame eletrocardiográfico seguiu o sistema de derivação bipolar base-ápice, com os animais em repouso, utilizando-se um aparelho ECG-PC TEB. Foram determinadas a frequência (FC) e ritmo cardíaco, morfologia, duração e amplitude de ondas e complexos e duração de intervalos. Os resultados foram submetidos ao teste ANOVA e teste Tukey com probabilidade de erro de 5%. A auscultação cardíaca evidenciou além dos sons cardí-acos normais S 1 (100,0%), S 2 (100,0%), S 3 (19,0%) e S 4 (34,0%), presença de sopro funcional sistólico e diastólico

This research was performed by a multidisciplinary and interagency team and sought to determine the blood profile, total plasma protein and fibrinogen concentrations of clinically healthy adult Campeiro horses. A total of 138 horses (14 stallions, 74 non-pregnant and 50 pregnant mares)

RESUMOAmostras de sangue foram obtidas de 138 equinos registrados da raça Campeiro, com idade média de 9,7±5,4 anos, sendo 14 machos (10,15%) e 124 fêmeas (89,85%). Observaram-se valores médios da atividade sérica de GGT: 13,73±4,08 U/L; AST: 246,34±72,87U/L; ALT: 5,13±1,18U/L; FA: 284,32±53,33UI/L; CK: 132,54±72,25U/L; LDH: 511,38±143,65U/L; e das concentrações séricas de ureia: 38,65±12,62mg/dL e de creatinina: 1,24±0,24mg/dL. Os valores médios de AST, FA, ALT, ureia e creatinina foram semelhantes aos propostos na literatura para outras raças. Os valores de CK, GGT e LDH foram superiores aos comumente utilizados como referências. Não houve diferença nas concentrações de nenhum dos componentes séricos avaliados nas diferentes idades analisadas. Maiores valores médios nas concentrações de ureia e menores de creatinina foram observados nas fêmeas em relação aos machos, assim como a maior atividade sérica de FA em fêmeas gestantes em relação às éguas vazias. O perfil bioquímico sérico de equinos sadios da raça Campeiro apresenta variações peculiares que devem ser levadas em consideração na interpretação de exames laboratoriais.Palavras-chave: equino, Campeiro, análises clínicas, bioquímica sérica, enzimas GGT: 13.73 ABSTRACT Blood samples were obtained from 138 equines of the Campeiro breed with mean ages of 9.7±5.4 years, including 14 males (10.15%) and 124 mares (89.85%).

Accidents caused by insects of the Hymenoptera are rarely described in large animals. The attacks caused by honeybee (Apis mellifera) may cause severe consequences and its intensity changes according to the number of stings. Local and systemic reactions can occur, including progression to death. This report describes a case of honeybee attack on an equine, which took place in the city of Lages, in the state of Santa Catarina, Brazil. In the clinical assessment the horse showed apathy, anorexia, head and pectoral edemas, dyspnea, icteric mucosa, increased mandibular lymph nodes and darkened urine. The blood count showed anemia and serum biochemical tests suggested, muscular and hepatic lesions. The urinalysis test indicated hemoglobinuria and increased clotting time. Treatment included lactate Ringer’s solution fluid therapy, furosemide, promethazine, corticosteroids and 20% mannitol solution. Hot and cold compresses were applied alternately on areas with edema. There was a satisfactory response to treatment and the animal was discharged after 30 days in veterinary hospital. The description of honeybee sting accidents in large animals is important because of the evolution that can lead to death. The early approach associated with appropriate treatment, avoiding the worsening of the lesions is fundamental for the recovery of the patient.

Summary Horses with enterolithiasis may develop clinical signs of colic due to partial or complete obstruction of the right dorsal, transverse or small colon. Laparotomy followed by enterotomy at the site of obstruction or mobilisation of enteroliths to intestinal segments deemed more appropriate for incision is indicated in these cases. However, surgical removal of enteroliths lodged in nonexteriorisable intestinal segments and/or not amenable to mobilisation may be labour intensive and dangerous. Pneumatic impact (or ballistic) lithotripsy is a potential tool for surgical resolution of simple and complex cases of enterolithiasis in horses. This study describes the use of a pneumatic lithotripsy device for intraluminal enterolith fragmentation in five cases of enterolithiasis. Seven calculi were successfully fragmented. In four cases, fragmentation was achieved at the site of obstruction and fragments exteriorised through an enterotomy incision created for device introduction or advanced towards the rectum and removed. In two cases, enteroliths were manipulated back to the pelvic flexure, fragmented and removed. Findings of this study suggest that intraluminal enterolith fragmentation can be used to avoid long enterotomy incisions and facilitate removal of calculi lodged in bowel segments that cannot be exteriorised. However, it is important to be aware of the risks of enterolith fragmentation in nonexternalisable bowel segments that cannot be visualised for intestinal viability assessment.
