Abstract

Aim: In this study it was aimed to investigate the antibiotic susceptibilitiesand extended spectrum beta lactamase production of Escherichia colistrains isolated from various clinical samples sent to Tavsanli State HospitalMicrobiology Laboratory retrospectively. Material and Method: All of thecultures were examined for the agent and antibiotic susceptibilities. Forthe identification of bacteria, various chemical tests and BBL Crystal E/ NF (Beckton Dickinson, ABD) system was used. Antibiotic susceptibilitieswere investigated according to CLSI criteria on Mueller Hinton agar bydisc diffusion method. Double disc synergy method was used to investigateextended spectrum beta lactamase (ESBL) production. Results: 456 E. colistrains isolated from clinical samples were included in the study. E. colistrains were mostly isolated from urine according to clinical samples. Themost effective antibiotics against E. coli strains were imipenem, amikacineand sulbactam/cefoperazone. The least susceptibility was against ampicillin.ESBL production rate was found to be %15 in E. coli. Discussion: ESBLproducing E. coli which are the reason of expensive therapy and difficultiesin treatment of infections should be monitored for ESBL production ratiosby all of the centers, extended spectrum beta lactam antibiotics should buused carefully in treatment, hospitalized patients should be isolated andsurveillance should be done in the units under risk.

Özet

Amaç: Bu çalışmada Tavşanlı Devlet Hastanesi Mikrobiyoloji Laboratuvarınagönderilen çeşitli klinik örneklerden izole edilen Escherichia coli suşlarının antibiyotik duyarlılıkları retrospektif olarak incelenmiş, bu mikroorganizmaların genişlemiş spektrumlu beta laktamaz (GSBL) üretimlerinin belirlenmesiamaçlanmıştır. Gereç ve Yöntem: Kültürlerin tümü etken ve antibiyotik duyarlılıkları açısından irdelenmiştir. Bakterilerin tanımlanmasında çeşitli biyokimyasal testler ve BBL Crystal E/NF (Beckton Dickinson, ABD) sistemi kullanılmıştır.Antibiyotik duyarlılığı Müller-Hinton Agarda disk diffüzyon yöntemi ileCLSI kriterleri doğrultusunda değerlendirilmiştir. GSBL üretiminin araştırılması için çift disk sinerji yöntemi kullanılmıştır. Bulgular: Klinik örneklerdenizole edilen 456 E. coli suşu çalışmaya dahil edilmiştir. E. coli suşları gönderildiği örnek türüne göre değerlendirildiğinde en fazla idrar örneğinden izole edildiği görülmektedir. E. coli suşlarının en fazla duyarlı oldukları antibiyotiklerin imipenem, amikasin ve sulbaktam/sefoperazon oldukları belirlenmiştir. Duyarlılığın en düşük olduğu antibiyotik ise ampisilindir. GSBL üretim oranı E. colide %15 olarak tespit edilmiştir. Sonuç: Tedavisi pahalı ve güç enfeksiyonlara neden olan, GSBL üreten E. coli ve diğer Gram negatif enterik bakterilerin GSBL üretim oranları, her merkez tarafından izlenmeli, tedavide tercih edilen geniş spektrumlu beta laktam antibiyotikler dikkatlice kullanılmalı, yatan hastalar izole edilmeli, risk altındaki bölümlerinde sürveyans çalışması yapılmalıdır.
