Abstract
The enzymatic activities of 2 reference strains of H. ducreyi and 30 clinical isolates were investigated by conventional biochemical tests and the API-ZYM test kit system which included 97 synthetic substrates. No strains converted .DELTA.-aminolevulinic acid to porphyrins, but they all reduced nitrates to nitrites. All strains possessed aminopeptidase activity against .beta.-naphthylamide derivatives of L-alanine, L-arginine, L-glutamine, glycine, L-leucine, L-lysine and L-serine. No trypsin-or chymotrypsin-like activities were detected. All strains had phosphatase activity with broad pH range, and phosphoamidase activity. No glycosidase was detected by the substrates tested.This publication has 3 references indexed in Scilit:
