Prospective study of maternal and infantile infection with Chlamydia trachomatis.

We examined the prevalence of chlamydial infection in a population of pregnant women and observed their infants to determine the risk of development of ocular or respiratory infection. We examined endocervical and serum specimens from 322 pregnant women for Chlamydia trachomatis and chlamydial antibody. The cultures were obtained at the first prenatal visit.

Chlamydia trachomatis in women: antibody in cervical secretions as a possible indicator of genital infection.

One hundred eighty-five women college students were examined for genital infection with Chlamydia trachomatis. This organism was isolated from nine (5%) of the 185 women. Antibody was demonstrated in the genital secretions of 26 (14%) and in the serum of 70 (38%) of the women.

Microbiology of the vagina in children: normal and potentially pathogenic organisms.

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.

Immunity to vaginal reinfection in female guinea pigs infected sexually with Chlamydia of guinea pig inclusion conjunctivitis.

Guinea pig boars were inoculated intraurethrally with the chlamydial agent of guinea pig inclusion conjunctivitis (GPIC). At the heights of their urethral infections, they were caged with sows in estrus. Whereas some of the sows had not been previously exposed to GPIC agent, others had received an intravaginal inoculation 5 to 8 weeks earlier.
