Correlation of isolates from pyoderma and carrier sites.
100 cases of pyoderma were studied to find out whether there is any correlation between isolates from pyodermas, normal skin and nasal flora of the individual. From each patient six swabs were taken, two each from the lesion, healthy skin distant from the lesion and anterior nares. One swab from each site was used for direct microscopic examination and the other for culture and antibiotic susceptibility study. Isolates from lesion and normal skin and/or nose were identical in 37% cases of pyodermas. Isolates from lesion and normal skin were identical in 16% of cases; from lesion and nose in 14% cases, from all the three sites i.e., lesion, skin and nose in 7%. Staphylococcus aureus was the causative organism in 35 out of these 37 cases. Only in 2 cases was Staph albus isolated. In addition, antibiotic susceptibility pattern of the isolates were also the same in 12 out of these 37 cases.
