Vibrio cholerae in New Zealand
نویسنده
چکیده
Toxigenic strains of Vibrio cholerae, although not endemic in New Zealand, are isolated occasionally from recent overseas travellers. Isolates should be confirmed biochemically and serologically and the presence of cholera toxin genes established by a reference laboratory, as non-toxigenic strains are found here in the summer months. Serotypes O1 and O139 are the causative agents of epidemic cholera, but the potential exists for other serotypes to become of public health significance because the production of cholera toxin is phage-encoded. It is also likely that the receptor enabling uptake of the cholera toxin phage and attachment of the organisms to the gut wall is phageencoded, and thus both virulence factors are potentially transferable to previously non-pathogenic vibrios. Toxigenic strains of Vibrio cholerae are notifiable in New Zealand.

Cholera outbreak is more common in developing countries. The causative agent of the disease is Vibrio cholerae strains O1 and O139. Traditional diagnostic testing for Vibrio is not always reliable, because Vibrio can enter a viable but non cultivable state. Therefore, nucleic acid-based tests have emerged as a useful alternative to traditional enrichment testing. In this investigation, a...
