Antioxidant enzymes in trichomonas vaginalis

The activities of artificial donor peroxidase, catalase, and superoxide dismutase in clinical isolates of T. vaginalis were studied. None of the tested strains exhibited activity of the three enzymes. Inclusion of catalase in Diamond -TYM solid medium did not support growth under aerobic conditions. The correlation between the absence of these enzymes and the growth conditions of the organism is discussed
