Experiments in human volunteers with trachoma and inclusion conjunctivitis agent

Abstract

The isolation of two strains of trachoma virus and one strain of inclusion conjunctivitis virus from Japanese cases of trachoma and inclusion blenorrhoea is described. The results of human inoculations with these strains and with one American strain are discussed. A quantitative difference in the severity of clinical symptoms due to different strains is likely to be present, but no qualitative difference was demonstrated among the strains, even between trachoma and inclusion conjunctivitis.
