Abstract
The paper provides a description of 112 Haemophilus strains isolated from cases of conjunctivitis in Egypt, Tunisia, Denmark and the USA, and aims at a clarification of the taxonomy of haemphili implicated in conjunctivitis. Although the study confirms the diversity of haemophili which can be isolated from inflamed conjunctivae, the vast majority of strains could be assigned to either biotype II or III of H. influenzae. Thirteen strains possessed all the characteristics of the Koch-Weeks bacillus. Judged by the findings the recognition of the Koch-Weeks bacillus as a separate species does not seem tenable. This organism may be considered a hemagglutinating variety of H. influenzae biotype III. The hemagglutinating ability per se, which can be found in strains of several taxa of Haemophilus, is apparently associated with a special pathogenic potential.
