“…In cows, asymptomatic individuals shed similar viral titers to those of clinically infected individuals, and the roles of virulent and avirulent strains of rotavirus have been postulated (40,41). In dogs and pigs, species in which asymptomatic infections are more frequently recognized (35,(42)(43)(44)(45), no population-based studies of sufficient power exist to truly characterize the role of asymptomatic infection. Asymptomatic infection may be a reflection of the nature of the relationship of G6P [9] and G3P [9] with the feline host.…”

The identification of pathogens of viral (Rotavirus, Coronavirus), parasitic (Toxocara spp.) and bacterial (Escherichia coli, Salmonella spp., Rhodococcus equi) origin shed in feces, and the virulence profile of R. equi and E. coli isolates were investigated in 200 samples of sand obtained from 40 parks, located in central region of state of Sao Paulo, Brazil, using different diagnostic methods. From 200 samples analyzed, 23 (11.5%) strains of R. equi were isolated. None of the R. equi isolates showed a virulent (vapA gene) or intermediately virulent (vapB gene) profiles. Sixty-three (31.5%) strains of E. coli were identified. The following genes encoding virulence factors were identified in E. coli: eae, bfp, saa, iucD, papGI, sfa and hly. Phylogenetic classification showed that 63 E. coli isolates belonged to groups B1 (52.4%), A (25.4%) and B2 (22.2%). No E. coli serotype O157:H7 was identified. Eggs of Toxocara sp. were found in three parks and genetic material of bovine Coronavirus was identified in one sample of one park. No Salmonella spp. and Rotavirus isolates were identified in the samples of sand. The presence of R. equi, Toxocara sp, bovine Coronavirus and virulent E. coli isolates in the environment of parks indicates that the sanitary conditions of the sand should be improved in order to reduce the risks of fecal transmission of pathogens of zoonotic potential to humans in these places.

“…O vírus detectado no presente estudo apresentou um padrão eletroforético que é típico do grupo A dos rotavírus, onde estão inseridos a maioria dos vírus detectados em humanos. Em estudo recente foram detectados rotavírus em fezes de dois cães assintomáticos, apresentando perfil de eletroferótipos do tipo 4:2:3:2 (Ruiz et al 2009). Semelhantes aos encontrados neste estudo, reforçando a importância que estes animais que circulam livremente nas ruas e residências, podem ter na contaminação ambiental com fezes, o que pode representar um problema sanitário sério em áreas urbanas e suburbanas.…”

Os rotavírus do grupo A, são frequentemente associados com gastroenterites em mamíferos e aves. O objetivo deste trabalho foi detectar a presença de rotavírus em fezes de cães sintomáticos e assintomáticos para diarréia aguda. Foram coletadas 32 amostras de fezes de cães. Todas as amostras foram submetidas à extração do RNA viral seguida da Eletroforese em Gel de Poliacrilamida (EGPA), onde se identificou apenas 1 (um) caso de infecção por rotavírus, em amostra assintomática. A análise do eletroferótipo mostrou um perfil 4:2:3:2 longo, e a homologia dos eletroferótipos de rotavírus humano e canino foi muito alta, sugerindo uma possível infecção interespécie.
