Astrovirus-like particles, adenoviruses and rotaviruses associated with diarrhoea in piglets.
Faecal specimens from 1- to 7-week-old piglets (n = 251) with acute diarrhoeal illness were examined by direct negative staining electron microscopy for the presence of viral agents. Rotaviruses were observed in almost 40% of cases while adenoviruses and astroviruses were also observed in 3 specimens each. The majority of the rotaviruses reacted with a commercial Group A rotavirus ELISA although in 11 specimens they did not react with the Group A antigen and could represent atypical rotaviruses. This is the first report of adenoviruses and astroviruses in diarrhoeal faecal specimens from pigs in South Africa.
