The aim of this study was to analyse the composition of the bacterial flora in 295 @entity1 who underwent surgical treatment in our clinic throughout the period of 12 years. 448 specimens were bacteriologically examined. Bacterial pathogens were isolated from 390 (87.1%). Among aerobic bacteria, @entity797 was the most often isolated (35.6% - from the peritoneum, 17.8% from the wound). Among anaerobic bacteria, @entity2868 - 44.9% were the most often isolated. 530 aerobic bacterial strains from @entity797 , Enterobacteriaceae, Staphylococcus and the nonfermentable rods were carefully analysed. Special attention was paid to the development of the resistance to 3 antibiotics ( @entity2891 , @entity2177 and @entity801 ) in 3 time periods: from 1984 to 1987, from 1988 to 1992 and from 1993 to 1996. Resistance of the bacterial strains to @entity2891 was 38.7% in the first time period; 39.5% in the second; and later increased to 53.8%. Resistance to @entity2177 was identical in the first two periods - 10.3%; and subsequently, it increased to 22.6%. The increase of resistance to @entity801 was the most significant--it went up from 24.5% to 44.8 and then dropped to 40.3%. CONCLUSION: Constant monitoring of the bacterial flora enables rational antibiotic application, which is essential due to the observed increase of bacteria strain resistance.
