Abstract
Detection of the isolation frequency and antimicrobial resistance of microorganisms causing meningitis would be helpful to physician in selecting the empiric treatment. In this study, the aim was to investigate the antimicrobial susceptibilities of the pathogens isolated from cerebrospinal fluids of patients with suspected meningitis in a four-year period. Microorganisms were isolated in 74 (8.3%) of 889 cerebrospinal fluid cultures. Staphylococcus aureus (33.8%) and coagulase negative staphylococci (14.9%) were the most common pathogens. They were followed by Streptococcus pneumoniae (8.1%), and Neisseria meningitidis (6.7%). Oxacilline resistance was 42% for S.aureus and 70% for coagulase negative staphylococci. Among S.pneumoniae isolates, there was no resistance to penicillin G, but 50% was resistant to ampicillin. All N.meningitidis isolates were susceptible to antibiotics of penicillin group. These results would be a helpful guide to physicians in selecting the empiric treatment for patients with meningitis in our hospital.

Key words: Antibiotic resistance, cerebrospinal fluid, meningitis



Beyin omurilik sıvılarından izole edilen mikroorganizmalar ve antibiyotik duyarlılıkları

Özet
Bir bölgede menenjite neden olan mikroorganizmaların türleri, sıklığı ve antibiyotik direnç durumlarının saptanması, klinisyenlere ampirik tedavi seçiminde yol gösterici olmaktadır. Bu retrospektif çalışmada, menenjit şüphesi ile bakteriyoloji laboratuvarımıza gönderilen beyin omurilik sıvısı (BOS) örneklerinden dört yıllık süre içerisinde izole edilen bakterilerin belirlenmesi ve tedavi seçiminde yol gösterici olabileceği düşüncesiyle antibiyotik duyarlılıklarının değerlendirilmesi amaçlanmıştır. İncelenmiş olan 889 BOS örneğinin 74'ünde (%8.3) mikroorganizma izole edilmiştir. Staphylococcus aureus (%33.8) ve koagülaz negatif stafilokok (%14.9) en sık izole edilen etkenler olmuştur. Bunları sırasıyla, Streptococcus pneumoniae (%8.1), Neisseria meningitidis (%6.7) izlemiştir. Oksasilin direnci, S.aureus izolatları arasında %42, koagülaz negatif stafilokoklarda ise %70 olarak saptanmıştır. S.pneumoniae izolatları arasında penisilin G direnci gözlenmez iken, ampisiline %50 oranında direnç görülmüştür. N.meningitidis ise, penisilin grubu antibiyotiklerin tamamına duyarlı bulunmuştur. Sonuçlarımızın, hastanemizde menenjit şüpheli hastalara başlanacak olan ampirik tedavide kullanılacak antibiyotiklerin seçiminde klinisyenlere yardımcı olacağı düşünülmektedir.

Anahtar Kelimeler: Antibiyotik direnci, beyin omurilik sıvısı, menenjit
