RESUMO
The ability of some strains of Vibrio parahaemolyticus to hydrolyze urea (uh+) can be used as a marker to predict which strains isolated from molluscan shellfish harvested in the Pacific Northwest are potentially pathogenic. The thermostable direct hemolysin-producing (TDH+) characteristic is a marker that is correlated with potential pathogenicity, and all of the TDH+ strains that we have isolated have been found to be uh+. Most of the uh+ strains belong to somatic antigen groups O3, O4 and O5. TDH+ strains are usually members of groups O4 and O5. The strains most often associated with human illness are members of the uh+, O4 group. The test for urease production is a simple screening test that can be helpful in predicting which strains are potentially pathogenic.
