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.
某些副溶血性弧菌菌株水解尿素的能力（uh+）可作为一个标志物，用于预测从太平洋西北部收获的软体动物贝类中分离出的哪些菌株具有潜在致病性。产生耐热直接溶血素（TDH+）的特性是与潜在致病性相关的一个标志物，并且我们分离出的所有TDH+菌株均已发现是uh+。大多数uh+菌株属于体细胞抗原组O3、O4和O5。TDH+菌株通常是O4和O5组的成员。最常与人类疾病相关的菌株是uh+、O4组的成员。尿素酶产生试验是一种简单的筛选试验，有助于预测哪些菌株具有潜在致病性。
