Neonatal conjunctivitis associated with Chlamydia trachomatis has been known since the beginning of the century. Isolation of chlamydiae in eggs, in conjunctivitis of newborns, and from the cervix of their mothers was achieved in the late 1950s. In volunteers, inoculations of ocular and genital strains caused conjunctivitis. Recent studies have shown that incidence figures of chlamydial conjunctivitis in infants are 0.5% to 4%, depending on the prevalence of genital infections by C. trachomatis in the pregnant women in the population studied. Younger women are more at risk. Recurrent, chronic infection and late sequelae may occur unless neonatal chlamydial infection, which is often multifocal, is effectively treated. Serious sequelae of chlamydial infection include pneumonia, which may develop in infants, and post-partum salpingitis, which may occur in infected mothers.

Ophthalmia neonatorum is one of the most common infections during the neonatal period. Chlamydia trachomatis and Neisseria gonorrhoea must be ruled out, given their high virulence and systemic complications. We describe a case of ophthalmia neonatroum from Klebsiella pneumonia. Gram-negative organisms have been reported in hospital-acquired conjunctivitis (HAC), but we are unaware of any published reports of K. pneumonia conjunctivitis in an otherwise healthy full-term infant born in the United States who has received prophylaxis. It is important to promptly identify and treat Klebsiella conjunctivitis because it can lead to severe complications.
