Virulence of trachoma-inclusion conjunctivitis agent after passage in baboons

The virulence of a strain of trachoma-inclusion conjunctivitis agent was increased by passage in baboons as judged by the severity of clinical signs and the number of inclusions found in conjunctival scrapings. Clinical scores increased substantially with a corresponding rise of from 5-20 to several hundred inclusions per conjunctival smear. Organisms from the heavily infected animals were reduced in infectivity for the baboon after 2 passages in chick embryos.
