TRIC Agents Isolated in the United States. X. Immunofluorescence in the Diagnosis of TRIC Agent Infection in Man.

Abstract

Summary Conjunctival scrapings from volunteers experimentally infected with TRIC agents and from patients with spontaneous eye disease were examined by immunofluorescence. Brightly fluorescing inclusions were demonstrated with hyperimmune TRIC anti-sera. The findings were compared with those obtained by Giemsa stain, iodine stain or isolation of the infectious agent in embryonated eggs. Immunofluorescence appears to offer an improved method for laboratory diagnosis of TRIC infections.
