Abstract
In a selected group of 103 babies referred with neonatal conjunctivitis, N. gonorrhoeae was isolated from 11 and C. trachomatis from 33. Concurrent infection was present in 3. One toddler sibling developed chlamydial conjunctivitis. After [tetracycline] treatment C. trachomatis was reisolated from 6 babies during the follow-up period. The discharge started 1-3 days after delivery in only 3 babies with gonococcal conjunctivitis and at 5-8 days in 8 babies. One baby was delivered by caesarean section. N. gonorrhoeae was isolated from 4 asymptomatic fathers, all of whom had urethritis. The mean onset of discharge in the 33 babies from whom Chlamydia was isolated was 7.1 days. One baby was delivered by caesarean section. Chlamydial conjunctivitis was associated with a high incidence of prematurity and of postpartum infection in the mother. Ten fathers of Chlamydia-positive babies were examined. C. trachomatis was isolated from 4, all of whom were asymptomatic but had low-grade urethritis. These findings confirm the pathogenic role of C. trachomatis in the cervix and indicate the importance to the family of an adequate microbiological investigation of neonatal conjunctivitis.
