| ABSTRACT: The presence of anti-Neospora caninum antibodies in beef cattle slaughtered in the northern region of the state of Paraná, Brazil, was evaluated. A total of 401 blood samples were collected; 281 samples from the municipality of Rolândia and 120 from the municipality of Borrazópolis, between April 2015 and November 2016. Of the total samples, 289 were from females and 112 from males, aged one and a half to eight years. Indirect fluorescent antibody test (IFAT) was performed, using a cut-off of 1:100. Variables were tabulated for statistical analyses (Fisher’s exact test and chi-square tests, p≤0.05). The analysis showed that of the 401 samples, 37 were positive for N. caninum, indicating a prevalence of 9.2 %, and observed titers were 1:100 (16),... |

| Um experimento foi realizado com o objetivo de verificar os efeitos da indução do consumo de água com edulcorante, na fase de berçário (10 aos 30 dias de idade), sobre o desempenho de 270 leitões (machos e fêmeas) submetidos ao desmame precoce segregado e os efeitos residuais nas fases de pré-creche (30 aos 45 dias) e de creche (45 aos 62 dias de idade). Três tratamentos com dois sexos e três repetições (fatorial 3 x 2) foram utilizados dos 10 aos 30 dias de idade dos leitões, sendo: T1- água sem edulcorante, T2 - água com edulcorante e T3 - água com e sem edulcorante oferecidos simultaneamente em bebedouros distintos. Foram avaliados o ganho diário de peso, o consumo diário de ração e a conversão alimentar. O consumo diário de água somente foi medido na... |

| Listeriosis is a disease primarily of ruminants caused by the Gram-positive bacterium Listeria monocytogenes. Ruminants either demonstrate manifestations of the encephalitic, septicemic, or reproductive form of listeriosis. The pathological and molecular findings with encephalitic listeriosis in a 5.5-month-old, male, mixed-breed goat and a 3-year-old Texel-crossed sheep from northern Paraná, Brazil are described. Clinically, the kid demonstrated circling, lateral protrusion of the tongue, head tilt, and convulsions; the ewe presented ataxia, motor incoordination, and lateral decumbency. Brainstem dysfunctions were diagnosed clinically and listeriosis was suspected. Necropsy performed on both animals did not reveal remarkable gross lesions; significant... |

| Abstract 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... |
