Comparison of Campylobacter jejuni genotypes from dairy cattle and human sources from the Matamata-Piako District of New Zealand.

Faecal samples from 410 dairy cattle were collected from 36 farms in the Matamata-Piako district in New Zealand. Campylobacter jejuni was isolated on all 36 farms, with a prevalence of 51% (95% CI 45–57) in dairy cattle and 65% (95% CI 58–72) in calves. Twenty-one per cent of the bovine isolates and 43% of the human isolates formed indistinguishable clusters of at least one bovine and one human isolate. The results confirms that dairy cows and calves are a potential source of human campylobacteriosis. J Appl Microbiol. 2008 Nov;105(5):1354-60
