Incidence of adenoviral and chlamydial coinfection in acute follicular conjunctivitis.

PURPOSE/METHODS: After we studied a case of chlamydial and adenoviral coinfection in a 20-year-old woman, we determined the incidence of chlamydial infection in patients with acute adenoviral conjunctivitis. In a randomized retrospective study, we evaluated 100 specimens of patients with culture-proven adenoviral conjunctivitis. RESULTS/CONCLUSIONS: Three of 100 (3%) specimens tested positive for chlamydial DNA using polymerase chain reaction. Adenoviral and chlamydial coinfection is rare, yet should be considered in patients with prolonged follicular keratoconjunctivitis.
