[Cooperative inhibitory effects of cervical mucus and neutrophils on growth of Candida albicans].
Preparations of human cervical mucus were obtained from fifteen female volunteers with or without vaginal candidiasis. Their content of lactoferrin and inhibitory effects on the growth of Candida albicans were estimated. The concentration of lactoferrin in cervical mucus was measured by enzyme linked immunosorbent assay (ELISA). Lactoferrin concentration of the eleven preparations among them was more than 0.2 mg/ml. The effects of these cervical mucus preparations on Candida growth were examined in vitro. Candida growth was not inhibited by the addition of 1/200 diluted cervical mucus alone, however, anti-Candida activity of murine neutrophils was augmented by such an addition. These results suggest that the combination of neutrophils and cervical mucus may have an important role in defense against Candida infection in the vaginal mucosa.
