title: Cytopathic avian rotavirus isolated from duck faeces in chicken kidney cell cultures.
abstract: Five cytopathic viruses morphologically resembling rotaviruses were isolated from duck faeces in chicken kidney cell cultures using conventional methods. One of the isolates, designated F-29 strain, was identified as an avian rotavirus from the following: ribonucleic acid in the viral core, virus growth in the cytoplasm, resistance to chloroform, acid and heating, partial stabilisation to molar magnesium chloride and rotavirus-like morphology by electron microscopy. By immunofluorescence, F-29 strain did not react with porcine and bovine rotaviruses. Neutralising antibodies to the F-29 strain were detected in sera collected from a conventional duck flock, but not from specific-pathogen-free duck flocks.
