The problems in monitoring and assessing water quality that must be overcome most urgently are associated with the development of appropriate, simple methods for detecting living but not necessarily growing indicator and pathogenic microorganisms. Th

New Zealand isolates of Vibrio anguillarum from water, sediments and healthy salmon were tested for their ability to grow under iron‐limiting conditions and to produce sidero‐phores. Their growth in the presence of the iron chelator ethylenediami

Thirty strains of V. anguillarum were tested for the production of inhibitory substances against closely-related bacteria using the deferred antagonism test. Only one strain, Vibrio anguillarum VL4355, inhibited strains of V. ordalii and this effect

This paper describes a method for the detection of faecal pollution in water, using a gene probe based on the Escherichia coli K-12 gene, uidA , which encodes β-glucuronidase (GUD). GUD has been reported to be produced by 97–99.5% of E. coli and w

Virio angullarum, which is considered to have world‐wide distribution, is responsible for significant fish losses in commercial aquaculture. Samples of water, sediment, macroalgae, and salmon from selected New Zealand sites were tested for the pres

Bacterial epiphytes on the surface of the fresh-water plant Alisma plantago-aquatica collected from a polluted river were found to be a major factor in contributing to the total metal concentrations of the plant. The removal of epiphytes from the lea

Surveys were carried out over 16 months to assess the distribution of enteroviruses of human origin in sediments and mussels near two sewage outfalls on the North Taranaki Coast, New Zealand. Enteroviruses were present in high numbers in both sedimen

Rhizosphere bacteria have been found to concentrate molybdenum (Mo). Investigations of where in the cell this Mo is bound have shown that the Mo is mainly bound by a passive process to the extra-cellular cell layers. Some Mo is bound to the cell wall
