A Clinical and Bacteriological Study of Pyodermas

Abstract

Clinical and bacteriological study was carried out in 100 cases of Pyodermas to find out the causative organism and their antibiotic sensitivity patterns. Maximum cases were of impetigo (31%) followed by furunculosis (24%), folliculitis (22%), pyogenic intertrigo (6%), sycosis and carbuncle (6% each), ecthyma (2%) and cellulitis (1%). Majority of the cases belonged to age group of 0-10 years. A total of 99 isolates from 100 cases with pyodermic lesions were isolated. Single infecting organism was isolated from 85.85% and more than one type of organisms from 7.07% of cases. No organism was isolated from 9.09% of cases. Coagulase positive Staphylococcus (80.8%) was the predominant species isolated followed by Beta-haemolytic streptococcus (13.13%) and Esch. coli (3.03%). Staphylococcus aureus showed highest sensitivity to Gentamicin, Erythromycin and Cephalexin and high resistence to Tetracycline, Penicillin and Polymixin. Streptococcus Beta-haemolyticus was highly sensitive to Gentamicin, Cloxacillin and Tetracycline and less sensitive to Penicillin and Ampicillin. Most of the strains were found to be resistant to one or more antibiotics.
