title: Neuraminidase production by Candida albicans.
abstract: A Candida albicans strain G42, isolated from a vaginal infection, was demonstrated to produce neuraminidase in culture filtrates with activity for N-acyl-neuraminic acid glycoprotein from bovine submaxillary gland, and human erythrocytes as substrates. Incubation of viable cells from G42 with human group O Rh(+) erythrocytes released N-acetyl-neuraminic acid in a time-dependent manner. Thirty-two clinical isolates of C albicans were studied for neuraminidase production. Enzyme activity was found in culture filtrates from five strains.It would appear important from these data to determine whether the production of neuraminidase by C albicans can be correlated with pathogenicity.
