“…This result possibly relates to the mandatory controlling measures, through vaccination and periodical inspections with the elimination of positive animals (BRAZIL, 2006). Although the brucellosis control program is running since 2006, Viana et al (2009) reported 3.5% of occurrence of this disease in their study.…”

The aim of this study was to measure the occurrence of brucellosis, leptospirosis and neosporosis in cows from 25 family farms milk, with semi-intensive grazing system, located in the Southwest region of Paraná, Brazil. Eighty-four cows with retained placenta, between July 2013 to July 2014, diagnosed by the presence of fetal membranes in the uterus up to 12 hours after partum, decrease of appetite and of milk production, as well increase of rectal temperature were included into the study. The animals were submitted to blood collection for evaluating the seropositivity for brucellosis, leptospirosis and neosporosis. The blood was collected at 15 to 45 days postpartum, avoiding false negative results due to immune deficiency observed in the transition period. After collection, the blood was centrifuged, the serum was packed in three aliquots, identified and subsequently frozen. Serology was performed to diagnose brucellosis (technique of buffered acidified antigen), leptospirosis (through the microscopic agglutination test - MAT) and neosporosis (indirect immunofluorescence test). Animals were considered positive when presenting titer >1:100 (leptospirosis) and 1:200 (neosporosis). No animal with placenta retention presented Brucella abortus bacteria; 39% (33/84) were reactive to one or more Leptospira serovars, 15% (13/84) were positive to Neospora caninum, and 4% (4/84) had both diagnosis, being reactive for leptospirosis and neosporosis. In conclusion, data from this experiment inspires greater attention to leptospirosis and neosporosis in dairy cattle presenting placenta retention in southwest Paraná.

“…Foi realizado um questionário (Anexo) para o recolhimento de informações para o estudo epidemiológico da Leptospirose Bovina na região. Para cada propriedade rural os proprietários responderam perguntas referentes aos pontos determinantes da doença como: protocolo vacinal, tipo de criação e alimentação, prevalência de doenças reprodutivas, manejo reprodutivo; e fatores de risco como: presença de roedores e criação conjunta (Banchiero Júnior et al, 2014;Paixão et al, 2016;Viana et al, 2010).…”

The objective of this study was to investigate the prevalence and risk factors of Leptospirosis in dairy herds of the Rio Doce, ES, composed of six municipalities: Aracruz, Ibiraçu, João Neiva, Linhares, Rio Bananal and Sooretama. The properties were randomly selected, with two properties per municipality. It was admitted as a criterion for selecting these properties because they did not present the management of anti-Leptospira vaccination in the animals. The number of blood samples in each property was according to the availability of animals, which totaled 100 blood samples. The serological technique used was Microscopic Soroagglutination (SAM). Serum samples were submitted to dilutions of 10 (ten) live antigens, including the serovars L. australis, L. butembo, L. copenhageni, L. bratislava, L. canicola, L. grippothyphosa, L. hardjo prajitno, L. L. pomol, L. icterohaemorrhagiae, L. Wolffi of the genus Leptospira spp. of the species interrogans.The prevalence of serovars in this study was from Wolffi (24%); Bratislava (15%); Hardjo prajitno (11%); Pomona (10%); Butembo (10%); Australis (8%); Canicola (5%); Ichterohaemorragiae (5%); Grippotyphosa (4%); Copenhageni (3%). The results demonstrate that bovine Leptospirosis is present in the mesoregion with 50% prevalence in individuals, the main risk factors being non-vaccination, presence of rodents, joint breeding and open herd.
