The identity of haemophili isolated in our laboratories from eye swabs was investigated. Ten out of 114 strains belonged to capsulated types of H. influenzae. Seventy-six strains were submitted to tests for the identification of H. aegyptius (the Koch-Weeks bacillus), but none was proved to belong to this species. An unexpectedly high proportion of the haemophilus strains, including most of those with capsules, came from patients with lachrymal duct obstruction.
