[Species makeup, biological activity and antibiotic sensitivity of the microbes isolated from patients with a surgical infection].

Specimens from 227 patients with purulent surgical infections of various localization were tested. The microbial growth was observed in 87.6 per cent of the patients, staphylococci being found in 80.8 per cent of them. The plasma coagulating properties were detected in the staphylococci from 84.2 per cent of the patients among the total number of the staphylococcal isolates. Staphylococci were mostly isolated from the patients with osteomyelitis, infected wounds. Monocultures of the microbes and associations were found in 78.8 and 22.1 per cent of the patients respectively. The microbial associations were observed most often in cases with the diseases of the respiratory organs or abdominal cavity and osteomyelitis as compared to the cases with infected wounds. As dependent on the origin, the staphylococci in the patients of various groups differed by their phage type characteristics. Most of the isolates were sensitive to erythromycin, monomycin and neomycin (84 to 99.1 per cent). The antibiotic sensitive staphylococci were isolated more frequent from the cases with osteomyelitis and the diseases of the respiratory organs as compared to the other nosological forms.
