Abstract

Some of the causes of neonatal diarrhoea in suckling calves aged up to 10 weeks were examined. The susceptibility of calves to the diarrhoea-inducing effect of calf rotavirus was found to be age dependent. Calves over 6 days old were resistant to clinical diarrhoea although they did excrete virus in their faeces and subsequently developed antibody to rotavirus. An enterotoxigenic E. coli (ETEC) inoculated orally into either gnotobiotic or suckling calves aged 1 to 26 days did not cause diarrhoea. In contrast, diarrhoea was consistently produced in gnotobiotic and suckling calves between one and 15 days of age when they were inoculated with both calf rotavirus and ETEC. In general, diarrhoea appeared after a rotavirus incubation period of approximately 3 days and was independent of the order in which the 2 microbial agents were given.
