Changing phage pattern of Staphylococcus in pyoderma cases.

Abstract

Staphylococcus aureus is a major pathogen for pyoderma in India. Phage pattern of bacteria gives valuable information in epidemiological studies of infection. Two hundred and two strains of Staphylococcus aureus isolated from pyoderma cases at Gorakhpur, were phage grouped and phage typed. It was found that 43.1 percent strains were not typable. Most common group was mixed phage group (23.8 percent) followed by phage group III (12.4 percent). Predominant phage types in mixed phage group was 84/81/85 and in phage group III was 84/85.
