An outbreak of diarrhoea associated with atypical rotaviruses in goat kids

The presence of rotaviruses was investigated in the faeces of 31 goat kids in a dairy herd that experienced an outbreak of severe diarrhoea which caused dehydration, anorexia and prostration in seven (22.6 per cent) of them. All the affected animals were two to three days old. A group A-specific ELISA failed to detect rotaviruses in any of the samples but the characteristics electropherotype of group B rotaviruses was observed by electrophoresis in polyacrylamide gels in six of the animals. A highly significant statistical association between the shedding of rotavirus and the occurrence of diarrhoea was demonstrated. All the rotaviruses were detected in animals three to four days old. Cryptosporidium parvum, Clostridium perfringens and enterotoxigenic Escherichia coli were not detected in the seven diarrhoeic animals.
