Transposon-induced pigment-deficient mutants of Porphyromonas gingivalis.

FEMS microbiology letters - 15 Nov 1994

Hoover C I, Yoshimura F

Abstract excerpt

Trypsin-like protease activity, hemagglutination activity, and accumulation of heme-containing compounds (black pigment) are considered to be virulence factors of Porphyromonas gingivalis. Transposon-mutagenesis was used for the first time to isolate pigment-deficient mutants. These mutants exhibited simultaneous deficiency in trypsin-like protease activity and hemagglutination activity. Two major...
