Parvovirus-like particles associated with diarrhea in unweaned piglets.

摘要: Numerous parvovirus-like particles, 18 to 26 nm in diameter, were detected by electron microscopy the intestinal contents of two three week old piglets with mild severe diarrhea, six Quebec pig herds. Hemagglutination guinea and African green monkey red blood cells was obtained clarified contents. Two isolates found be antigenically related porcine canine parvoviruses, while another differed from parvovirus using hemagglutination-inhibition test. Three could cultivated cell cultures as demonstrated development a cytopathic effect, hemagglutination activity, immunofluorescence identification virions culture fluids microscopy. The possibility primary etiological role for these parvoviruses diarrhea unweaned is discussed.
