[Pyrazinamidase activity of bacteria from Enterobacteriaceae family as characteristic for taxonomy].
Pyrazinamidase activity in 330 strains of bacteria from Enterobacteriaceae family (14 genus, 27 species) has been assessed. Pyrazinamidase activity detected in species from following genuses: Citrobacter, Escherichia, Klebsiella, Kluyvera, Morganella, Providencia, Raourtella, Salmonella, Shigella, and also in Proteus mirabilis, and nonpathogenic serovars of Yersinia enterocolitica, Y. frederiksenii. Pirasinamidase was absent in Serratia (S. marcescens, S. liguefaciens), Hafnia alvei, P. vulgaris, P. penneri, Y. pseudotuberculosis and pathogenic serovars of Y. enterocolitica. Absence of pyrazinamidase activity in bacteria from Hafnia and Serratia genus is a key taxonomic characteristic for identification of enterobacteria with microvolume assay technology.
