AbstractOne hundred new cases of pyodenna attending King George Hospital, Vishakhapatnam were investigated bacteriologically with antibiotic sensitivity of all the strains isolated and phage typing of coagulm positive staphylocci. Among these 50 had impetigo and 15 each ahd furunculosis and fouiculitis. The remaining included various other clinical entities. Children under 10 years were observed to have high incidence of pyoderma. A total of 88 strains of staphylococci (77 coagulase positive and 11 coagulase negative strains) 25 strains of beta haemolytic streptococci and 3 strains of Klebsiella were isolated. Staphylococci were found to be the commonest aetiological agents either single or in association with other organisms. Of the 76 strains of coagulase positive staphylococci 32 strains were not phage typable and among the 44 typable strains 17 (38%) belonged to group III and 15 (36.5%) to mixed group. Coagulase positive staphylococci showed high sensitivity to garamycin, kanamycin and erythromycin and high resistance to penicillin and streptomycin. Multiple drug resistance was also high among these strains. Coagulase negative staphylococci were found to be more sensitive with less incidence of multiple drug resistance. Most of multiple drug resistant strains belonged to group III phage types. Beta haemolytic streptococci were found to be highly sensitive to all the antibiotics tested.
