Detection of viral particles in feces of young dogs and their relationship with clinical signs Detecção de partículas virais em fezes de cães jovens e sua relação com sinais clínicos
Gross and light microscopic studies of 100 stool specimens of young dogs were carried out. Viral particles were detected in 31% of the analized samples using negative contrast electron microscopic diagnostic technique. Parvo-like virus, corona-like virus and other non-identified particles were observed in 17%, 7% and 2% of the samples, respectively. Parvo-like and corona-like viruses were found together in 5% of the samples. More than half (58.82%) of the positive parvo-like virus specimens were from dogs aged between 6 weeks and 6 months. 42.85% of the corona-like virus positive samples were detected in dogs between 6 weeks and 6 months and a similar percentage was found in dogs older than six months of age. Dual infections with parvo-like and corona-like viruses were observed in 5% of the samples. Unidentified virus-like particles were found in two specimens. 80.63% of the samples containing viral particles were obtained from dogs with diarrhea.<br>Foram analisadas macroscópica e microscopicamente 100 amostras de fezes de cães jovens colhidas em ambulatório clínico. Através de microscopia eletrônica de contraste negativo, foram detectadas partículas virais em 31% das amostras de fezes examinadas. Do total de amostras onde foram detectadas partículas virais, 17% continham partículas parvo-like, 7% continhan partículas corona-like virus e 2% continham partículas com morfologia não característica. Em 5% das amostras foi detectada a presença simultânea de partículas parvo-like e corona-like. Do total de amostras de fezes contendo partículas parvo-like, 58,82% eram de cães com 6 semanas a 6 meses de idade, o que também foi observado em 42,85% das amostras de fezes contendo partículas corona-like foram cães entre 6 semanas e 6 meses e um número semelhante foi encontrado em cães de mais de 6 semanas de idade. Uma dupla infecção de parvo-like virus e corona-like virus, foi confirmada em 5% dos especimens. Partículas "virus-like" não identificadas foram encontradas em 2 indivíduos Das amostras com identificação de partículas virais, 80,64% pertenceram a cães com diarréia
