Clinical and bacteriological study of impetigo contagiosa

ABSTRACT

This work included clinical and bacteriological examination of 102 patients with active impetigo lesions in both forms of ordinary vesicular impetigo contagiosa [89 patients] and bullous impetigo [13 patients] of both sexes. The possible predisposing factors were hot and humid climate, sweat rash, septic foci and 50% of cases with scalp affection were infested with pediculosis capitis. In the present study, out of 89 patients, it was found that the mixed infection of Staphylococcus aureus and group A beta-hemolytic streptococci constitute the majority of cases [43.8%], followed by pure Staphylococcus aureus form [34.9% of cases] and A beta-hemolytic streptococci were cultured from 20.2% of cases. In cases of bullous impetigo, out of 13 cases Staphylococcus aureus in pure culture was recovered from 61% of cases. Mixed culture of group A beta-hemolytic streptococci and Staphylococcus aureus were isolated from 23% of cases and group G beta-hemolytic streptococci with Staphylococcus aureus were isolated from 7.7% of cases
