Abstract:Background. An optimal vaginal microbiota dominated by Lactobacillus spp. protects women against acquiring and transmitting HIV in contrast to a nonoptimal vaginal microbiota exemplified by bacterial vaginosis (BV); however, the virucidal activity of carboxylic acid metabolites present in vaginal fluid is not well defined. Here we determined the HIV-1 virucidal activity of lactic acid (LA), short chain fatty acids (SCFAs) and succinic acid under conditions observed in women with a Lactobacillus-dominated vagi… Show more
