Abstract

Acid fast bacilli (AFB) smear and culturing the organism are conventional methods for the diagnosis of mycobacterial infections. FASTPIaqueTB is a rapid test that utilises bacteriophage amplification technology for the detection of viable Mycobacterium tuberculosis in clinical specimens. This test can detect 100-300 bacilli/mL and the results are available in 24 hours. We evaluated the performance of the FASTPIaqueTB test by comparing with BACTEC 460 TB culture system, polymerase chain reaction (PCR) and AFB smear met-hods. We investigated 58 sputum specimens sent to our laboratory. Seventeen AFB smear positive speci-mens were also positive by FASTPIaqueTB test, BACTEC 460 TB culture system and PCR method. Twenty two of 41 specimens that were negative by microscopy were positive by BACTEC 460 TB culture system and 18 of 41 specimens were found as positive by FASTPIaqueTB test and 17 of 41 specimens were positi-ye by PCR.. One specimen was evaluated as positive only by PCR whereas one specimen was positive only by FASTPlaqueTB test. One of the specimens was found as positive by BACTEC 460 TB culture system and FASTPlaqueTB test. The sensitivities of AFB smear, PCR. and FASTPlaqueTB test were 43.6%, 84.6% and 87.2% respectively when we accepted BACTEC 460 TB culture system as gold standard. As a result of the evaluation of these three tests according to BACTEC 460 TB culture system we conclude that FASTPlaqueTB test has a good potential for rapid diagnosis of Mycobacterium tuberculosis infections.

Özet

Mikobakteriyel infeksiyonların laboratuvar tanısında aside dirençli basil (ARB) yayma ve mikroorganizmanın kültürünün yapılması klasik yöntemlerdir. FASTPIaqueTB testi, klinik örneklerden canlı Mycobacterium tuberculosis'm tanısı için uygulanan ve bakteriyofaj amplifikasyon teknolojisine dayanan hızlı bir testtir. Bu test 100-300 basil/mL saptama özelliğine sahip olup 24 saatte sonuç verebilmektedir. Çalışmamızda FASTPIaqueTB testinin performansı, BACTEC 460 TB kültür sistemi, ARB yayma ve polimeraz zincir reaksiyonu (PCR) yöntemleri ile karşılaştırılarak değerlendirildi. Bu amaçla laboratuvarımıza gönderilen 58 balgam örneği işleme alındı. ARB yayma pozitif bulunan 17 örnek, BACTEC 460 TB kültür sistemi, FASTPIaqueTB testi ve PCR ile pozitif sonuçlandı. Mikroskobik incelemede negatif değerlendirilen 41 örneğin, 22'si BACTEC 460 TB kültür sistemi ile 18'i FASTPIaqueTB testi ile, I7'si ise PCR ile pozitif bulundu. Bir örnekte sadece PCR ile, bir ör-nekte sadece FASTPIaqueTB testi ile, bir örnekte ise BACTEC 460 TB kültür sistemi ve FASTPIaqueTB tes-ti ile birlikte pozitiflik saptandı. BACTEC 460 TB kültür sistemi altın standart kabul edilerek, ARB yaymanın duyarlılığı %43.6, PCR yönteminin duyarlılığı %84.6, FASTPIaqueTB testinin duyarlılığı ise %87.2 olarak hesap-landı. BACTEC 460 TB kültür sistemine göre, bu üç yöntemin değerlendirilmesi sonucunda; FASTPIaqueTB testinin M. tuberculosis'm hızlı tanısında iyi bir potansiyele sahip olduğu sonucuna varılmıştır.
