OBJECTIVE: Determine the prevalence of the major enteric pathogens in dairy and dairy beef @entity291 with @entity294 in Australia. DESIGN: Cross-sectional study. METHODS: Faecal samples from 84 Australian dairy and dairy beef properties (597 samples) were screened for rotavirus and coronavirus using real-time reverse transcription polymerase chain reaction, for @entity5746 spp. using selective enrichment faecal culture, and for enterotoxigenic @entity526 (K99) and @entity2432 using a commercial enzyme-linked immunosorbent assay. A logistic regression with random effects model was used to compare prevalence of pathogens in dairy and dairy beef operations. RESULTS: Enteric pathogens were isolated from 97.6% of outbreaks and 95.0% of samples. Rotavirus was the most common pathogen identified (477/597, 79.9%) followed by @entity2432 (349/597, 58.5%), @entity5746 spp. (142/597, 23.8%), coronavirus (129/597, 21.6%) and @entity526 K99 (104/597, 17.4%). Multiple pathogens were identified on 96.4% of farms and from 71.0% of samples. Samples from dairy beef properties were more likely to have multiple pathogens than dairy properties (P < 0.05), whereas @entity6425 spp. were more likely to be identified in samples collected from dairy beef than dairy properties (P < 0.05). CONCLUSION: Most outbreaks of @entity291 @entity294 in dairy and dairy beef operations involve multiple pathogens. Rotavirus and @entity2432 were the most frequently identified pathogens across production systems. @entity5746 spp. and rotavirus were more frequently identified in dairy beef operations.
