Rapid detection by immunofluorescence of multiple viral infections in patients with keratitis.
The presence of 12 viral (herpes 1 and 2, influenza A(H1N1), A(H3N2) and B, parainfluenza 1, 2, 3, adenovirus 5) and inframicrobial (Chlamydia, mycoplasma, Rickettsia burneti) antigens was investigated by direct or indirect immunofluorescence (IF) reactions in exfoliated conjunctival cells from 110 patients with nonbacterial keratitis and keratoconjunctivitis. A rapid etiological diagnosis could be obtained in 101 (92%) of the cases, parainfluenza and herpes antigens being the most frequently detected. In most of the cases the simultaneous presence of several antigens was made evident. Encouraging results were obtained by the application of a specific treatment based on the diagnosis provided by the IF reaction.
