AMO, Alicia N. del; APREA, Adriana N. and PETRUCCELLI, Miguel A.. Detection of viral particles in feces of young dogs and their relationship with clinical signs. Rev. Microbiol. [online]. 1999, vol.30, n.3, pp.237-241. ISSN 0001-3714. http://dx.doi.org/10.1590/S0001-37141999000300009.
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.
