Association between Neospora caninum seropositivity and reproductive disorders in girolando cows / [Associação entre a soropositividade para Neospora caninum e distúrbios reprodutivos em vacas girolando]

The aim of this study was to investigate the presence of anti-Neospora caninum antibodies in Girolando cows, in order to evaluate the association between seropositivity and reproductive disorders. Blood samples were collected from 40 dairy cows in their reproductive phase from the cranial superficial epigastric vein. The blood samples were tested using the Indirect Fluorescence Antibody Test (IFAT) to detect anti-N.caninum antibodies. The serological results were used to verify whether there was any association with the manifestation of reproductive disorders based on data from the records of reproductive history from 2017 to 2018 as well as the clinical observations of the herd throughout this study. The Fisher exact test was used to verify the existence of an association between the serology and reproductive disorders, adopting a 95% confidence level. The serological results showed a 27.5% seroprevalence in the herd for N. caninum, however, after statistical analysis, no association between seropositivity and reproductive disorders was found in the evaluated herd. Although the studied population is infected with Neospora caninum, we can infer that anti-Neospora caninum antibodies present in Girolando dairy cows at the UFRRJ Dairy Cattle Facility are not associated with the occurrence of reproductive disorders.(AU)

O objetivo deste estudo foi investigar a presença de anticorpos anti-Neospora caninum em vacas Girolando, avaliando-se a associação entre a soropositividade e os distúrbios reprodutivos. Foram coletadas amostras de sangue da veia epigástrica superficial cranial de 40 vacas leiteiras em fase reprodutiva, sendo as amostras testadas pela reação de imunofluorescência indireta (RIFI) para detecção de anticorpos anti-N. caninum. A partir dos resultados sorológicos, foi realizada a verificação de associação, ou não, com a manifestação de distúrbios reprodutivos, coletados nos registros de histórico reprodutivo entre 2017 e 2018 e observações do rebanho no transcorrer do estudo. O teste exato de Fisher foi utilizado para verificar a existência de associação entre a sorologia e os distúrbios reprodutivos, adotando-se nível de confiança de 95%. O resultado do estudo demonstrou uma soroprevalência no rebanho de 27,5% para N. caninum, contudo, após análise estatística, não foi confirmada a associação entre soropositividade e distúrbios reprodutivos no rebanho avaliado. Apesar de a população estudada estar infectada com o Neospora caninum, pode-se inferir que anticorpos anti-Neospora caninum presentes em vacas leiteiras Girolando do Setor de Bovinocultura de Leite da UFRRJ não estão associados à ocorrência de distúrbios reprodutivos.(AU)

Pyocolpos in a Pinscher bitch: a case report

Diseases related to the urogenital system in both males and females, are common in clinical routine of smallanimal and represents important causes of morbidity and mortality in dogs and cats. Pyocolpos is a cysticdilatation of the vagina due to the accumulation of pus resulting from the genital tract obstruction. The maincause of obstruction is imperforate hymen, transverse vaginal membrane, or vaginal atresia.We present a caseof a three-year-old female Pinscher with a history of constipation for four days, even after administration oflaxatives and enema, and estrus for ten days without a report of cover. Physical examinations were performed,which revealed increased abdominal size. Ultrasound confirmed the presence of large amounts of vaginal fluid.Exploratory laparotomy was performed, which confirmed the diagnosis of pyocolpos. Although pyocolposis a rare congenital malformation in female domestic animals, this report of its existence underscores theimportance of more accurate clinical research when increased abdominal size is noted by veterinarians.
