Possible diagnostic value of aminopeptidases detected by chromogenic substrates in Enterobacteriaceae.
The presence of aminopeptidases revealed by three chromogenic substrates (chromozym PL, chromozym TH, and carbobenzoxy-glycyl-prolyl-arginine-p-nitranilide) has been investigated by a simple method in 153 strains of different genera and species of the family Enterobacteriaceae. The results suggest that the AP-PL, AP-TH, and AP-CGPA tests can be of diagnostic value for the identification of enterobacteria.
