Hasta dışkılarından izole edilen E. coli izolatlarının antibiyotiklere duyarlılıkları ve plazmit profilleri

Bu çalışmada, çeşitli hastaların dışkılarından izole edilen 80 adet Escherichia coli (E. coli) izolatının antibiyotik duyarlılıkları ve plazmit profilleri incelenmiştir. Bütün izolatlann ampisilin, mezlosilin, amoksisilin klavulanik asit, meropenem, sefoperazon, norfloksasin, gentamisin, aztreonam, seftriakson, imipenem, amikasin, siprofiaksasin. trimethoprim sulfametoksozol, nitrofurantôin ve seftazidime karşı duyarlılıkları saptanmıştır. Sonuç olarak, incelenen izolatlann %8 1.3 'ünün plazmit taşıdıkları görülmüştür. Bir izolatın taşıdığı plazmit sayısı 1-7 arasında, plazmit büyüklükleri ise 0.3 ile 15.4 MDa arasında değiştiği gözlenmiştir.

Antibiotic sensivity and plasmid profiles of E. coli strains isolated from patients

Eighty strains of Escherichia coli (E. coif) were isolated from patients. Antibiotic susceptibility of all the isolates for ampicillin, mezlocillin, amoxicillin clavulanic acid, meropenem, cefoperazone, norfloxacin, gentamicin, aztreonam, ceftriaxsone, imipenem, amikasin, ciprofloxacin, trimethoprim sulfamethoxazole, nitrofurantôin, ceftazidime, were tested. 81.3% of the isolates had plasmids. The number of plasmids of the isolates was between 1 and 7. Plasmid sizes ranged from 0.3 to 15.4 MDa.
