Pyrazinamidase activity as a phenotypic marker for several Aeromonas spp. isolated from clinical specimens.

Abstract excerpt

Negative pyrazinamidase activity was significantly associated with Aeromonas sobria, and positive pyrazinamidase activity was associated with A. hydrophila and A. caviae (chi 2, P less than 0.0001). The absence of pyrazinamidase activity may be a potentially significant phenotypic marker for A. sobria.
