“…Three different viruses, canine parvovirus (CPV), canine coronavirus (CCV) and rotavirus, have been shown to be associated with acute gastrointestinal disease and diarrhea in the dog (Keenan et al, 1976;Appel et al, 1978;Appel et al, 1979a,b;Eugster and Sidwa, 1979;England and Poston, 1980;Evermann et al, 1980;McNulty et al, 1980;Osterhaus et al, 1980b;Vandeberghe et al, 1980;Williams, 1980;Fulton et al, 1981;Johnson et al, 1983). The relative role of each of these viruses in causing gastrointestinal disease in this species has so far attracted limited attention (Osterhaus et al, 1980a). This is partly due to the lack of fast and reliable serological and virological assay systems for the screening of large number of serum and fecal samples.…”
