Microbiology of the Vagina in Children: Normal and Potentially Pathogenic Organisms

Abstract

Vaginal cultures from 100 healthy girls, 2 months to 15 years of age, were examined for the presence of normal and potentially pathogenic microorganisms. Corynebacterium vaginale, yeast species, and genital mycoplasmas were isolated from vaginal cultures from 13.5%, 28%, and 28% of the girls examined, respectively. Colonization with these organisms was not associated with signs or symptoms of vaginitis. Neisseria gonorrhoeae was isolated from a 4-year-old with purulent vaginitis. Trichomonas naginalis was recovered from two 13-year-olds, both of whom had an abnormal vaginal discharge. Vaginal antibody to Chlamydia trachoinatis was found in two girls, 4 and 13 years of age. In neither girl was the organism recovered from the vaginal culture. Chlamydia trachoniatis was recovered from the vaginal culture of another 4-year-old who had no abnormal findings on examination. Cultures from 59 of the girls were examined for aerobic and facultatively anaerobic bacteria. Diphtheroids and Staphylococcus epidermidis were the most frequently isolated organisms. Lactobacilli were isolated most frequently from the older girls, whereas enteric organisms were isolated most frequently from the younger girls.
