title: Unusual Yersinia enterocolitica strains recovered from domestic animals and people in New Zealand.
abstract: Twenty five isolates of Yersinia recovered from the faeces of cattle, sheep, goats and people in New Zealand were characterised biochemically and serologically and were found to be unrelated to any known Yersinia species. Two phenotypes were identified biochemically. Testing against all known O-factors of Yersinia showed that the isolates were serologically unique and two new serotypes were proposed, O:77 and O:78. Deoxyribonucleic acid relatedness studies indicated that the strains formed a homogeneous group, closely related to Yersinia enterocolitica. The definitive status of the isolates has not yet been decided.
