Özet
Amaç: Tüberküloz hastalığında, basilin kısa sürede sap- tanması ve izolatın anti-tüberküloz ilaçlara karşı duyarlı- lığının belirlenmesi, tedavi için çok önemlidir. Bu amaçla şüpheli hasta örneklerinin farklı iki yöntemle kültürü yapıl- mış ve üreme saptanan örneklerde anti-tüberküloz ilaçla- ra duyarlılık testi sonuçları irdelenmiştir. Gereç ve yöntem: Çalışmada hasta örnekleri homojeni- zasyon ve dekontaminasyon işlemlerinden sonra Zielh- Neelsen boyası ile boyandı. Her bir örnek Lowenstein- Jensen (LJ) ve Mycobacterium Growth Indicator Tube (MGIT) besiyerlerine inoküle edildi. İnkübasyon periyo- dunu takiben üreme saptanan örneklerdeki basillerin dört majör anti-tüberküloz ilaca karşı duyarlılıkları araştırıldı. Bulgular: Çalışmada 2007-2010 yılları arasında 163 fark- lı hastadan alınan örnekler değerlendirildi. Tüm örnek- lerde; Aside Dirençli Basil (ARB) pozitifliğinin 7 (%4.0), MGIT pozitifliğinin 6 (%3.5), LJ pozitifliğinin 7 (%4.0) ol- duğu tespit edildi. MGIT yöntemi tüberküloz basillerini LJ yöntemine göre belirgin olarak daha kısa sürede saptadı. İzole edilen bütün suşların dört major anti-tüberküloz ilaca duyarlı olduğu bulundu. Sonuç: Çalışmamızda; MGIT yönteminin tüberküloz ba- silini belirlemede LJ kültürüne belirgin şekilde üstünlük sağladığı saptandı ve üreyen suşlarda anti-tüberküloz ilaçlara karşı direnç belirlenmedi.
Objectives: As soon as possible to detection of tubercu- losis bacilli and to determination of their anti-tuberculosis drug susceptibilities are very important for an optimal anti-tuberculosis therapy. Therefore, two different culture methods in suspected patient samples were performed. The results of anti-tuberculosis drug susceptibility testing of culture positive samples were examined. Materials and methods: Following the homogenization and decontamination processes, patient‘s samples were stained with Ziehl-Neelsen dye and each preparation were inoculated separately onto Lowenstein-Jensen (LJ) and into Mycobacterium Growth Indicator Tube (MGIT) media. After incubation period, drug susceptibilities of ba- cillus in culture positive samples against four major anti- tuberculosis drugs were investigated. Results: The samples obtained from 163 different pa- tients between 2007 and 2010 years were evaluated. In all samples, it was determined that positivity of Acid Resistant Bacillus (ARB), MGIT and LJ media were 7 (4.0%), 6 (3.5%) and 7 (4.0%), respectively. MGIT meth- od was demonstrated significantly earlier growth than LJ method the tuberculosis bacillus. All isolates were found to be sensitive to four major anti-tuberculosis drugs. Conclusion: In our study, MGIT method was found to be superior to LJ media because of its quick result and drug resistance was not determined in all isolates.
