Gonorrhea: Bacteria Offer Protection
January 24, 2003
Researchers from the Uniformed Services University in Bethesda, Md., say certain species of lactobacilli may protect women from gonorrhea. The researchers tested the ability of four species of the bacteria commonly found in the vagina to inhibit the reproduction of Neisseria gonorrhoeae under different pH conditions. While all four inhibited growth in acidic conditions, only two were able to inhibit growth under neutral pH. The researchers believe that lactobacilli were able to inhibit growth by producing hydrogen peroxide. "On the basis of these data, one might hypothesize that the capacity of commensal lactobacilli to protect women against gonorrhea may depend on both the species and stage of menstrual cycle," said the researchers. The findings were published in Infection and Immunity (2002;70:7169-7171).Adapted from:
