Abstract

The purpose of the study was to evaluate rapid phage amplification assay in the determination of rifampisin resistance in Mvcobacterium tuberculosis. A total of 50 M. tuberculosis isolates from various samples of the patients with active tuberculosis (TB) out of which 25 isolates were resistant to at least rifampicin and 25 were susceptible to four major anti-TB drugs (isoniazid, rifampicin, ethambutol, streptomycin) were taken into the study. Susceptibilities of the isolates to anti-TB drugs were analyzed by resistance ratio and BACTEC 460 TB system. Rifampicin-resistant and rifampicin-susceptible isolates were analyzed by a commercially available rapid phage amplification test, FastPIaqueTB-RIF. Twenty-two isolates among 25 susceptible strains were found as susceptible by FastPlaque whereas three isolates were evaluated as intermediate. Twenty-four isolates out of 25 resistant strains were found as resistant by FastPlaque whereas one resistant isolate was evaluated as intermediate. When compared with conventional methods, sensitivity, specificity and overall accuracy of FastPIaqueTB-RIF were found as 96%, 88% and 92%, respectively. It is concluded that FastPIaqueTB-RIF test may be a useful tool for rapid and accurate detection of rifampicin resistance in M. tuberculosis.

Özet

Bu çalışmanın amacı, Mvcobacterium tuberculosis kökenlerinde rifampisin direncinin saptanmasında hızlı faj amplifikason yönteminin değerini saptamak idi. Aktif tüberkülozlu hastaların çeşitli örneklerinden soyutulan 25 en az rifampisine dirençli ve 25 dört majör ilaca (izoniyazit, rifampisin, etambutol ve streptomisin) duyarlı toplam 50 M. tuberculosis kökeni çalışmaya alınmıştır. Kökenlerin anti-tüberküloz ilaçlara duyarlılığı direnç oran ve BACTEC 460 TB sistemi ile analiz edilmiştir. Rifampisine duyarlı ve dirençli kökenler rifampisin direnci açısından, ticari olarak sağlanan bir hızlı faj amplifikasyon testi, FastPIaqueTB-RIF, ile incelenmiştir. Yirmibeş rifampisin-duyarlı susun 22'si FastPlaque He duyarlı ve üç sus orta duyarlı/dirençli olarak bulunmuştur. Yirmibeş rifampisin-dirençli suşun 24'ü FastPlaque He dirençli ve bir sus orta duyarlı/dirençli olarak bulunmuştur. Geleneksel yöntemler He karşılaştırıldığında; FastPIaqueTB-RIF testi için duyarlılık, özgüllük ve geleneksel yöntemler He uyumluluk, sırasıyla, %96, %88 ve %92 olarak saptanmıştır. Sonuç olarak, FastPIaqueTB-RIF testinin M. tuberculosis kültürlerinden rifampisin direncinin hızlı ve doğru bir şekilde araştırılması için kullanılabileceği düşünülmektedir.
