role of haemophilus aegyptius in mucopurulent conjunctivitis

This study included 160 cases diagnosed clinically as MPC. Identification of H. influenzae was done by morphological and cultural characteristics, X and V factor growth dependence and suger fermentation. Differentiation between H. influenzae biogroup aegyptius [H. aegyptius] and other H. influenzea species was done by xylose fermentation and biochemical teactions especially urea hydrolysis, ornithine decarboxylation and indole production using API 10 S kit. All strains of H. aegyptius were untypable by the polyvalent H. influenzae capsular antiserum H. influenzae strains counted for 30% of the isolates from the conjunctiva. The prevalence of H. aegyptius was found to be 54. 8% of the total isolated Haemophilus strains
