A clinical and bacteriological study of bacterial folliculitis

Lokesh S Jappa, Sameer R Kutre


Folliculitis constitutes a major component of pyoderma which is mostly caused by S. Aureus. However clinical and bacteriological studies are mostly lacking. This study was taken up to evaluate the proportion of various clinical types of bacterial folliculitis to decide regarding the most appropriate antibiotic of choice for folliculitis. A total of 100 untreated patients of folliculitis were enrolled in the study. Detailed history and clinical examination was done. Antibiotic sensitivity of pus was done when pus formation was evident in all cases of folliculitis. In present study, proportion of folliculitis was 5.61%. Folliculitis was commonest in the age group of 21 to 30 years. Sex ratio of male to female was 2.5:1. Folliculitis was more commoner in low socioeconomic status (69%). While it was most commonly seen in monsoon (49%). Positive family history was seen in 33% patients. Superficial folliculitis was commonest in children. Chronic folliculitis was mostly seen in adult males. Staph. aureus was isolated in 89% patients (including mixed growth of S. aureus and beta haemolytic streptococci) and Staph. epidermidis in 9% cases of folliculitis (including mixed growth of Staph. epidermidis and Beta haemolytic streptococci), Beta haemolytic streptococci was seen as mixed isolate in 7% cases. This study favours using cephalosporins as the first line of treatment in folliculitis on the basis of emergence of resistance strains. This study demonstrated the need of continuous monitoring of the changing pattern of antibiotic sensitivity.
