Five Years’ Evaluation of BD ProbeTec system for the direct molecular detection of Mycobacterium tuberculosis complex in respiratory and nonrespiratory clinical samples
Journal Title: Polish Journal of Microbiology - Year 2015, Vol 64, Issue 4
Abstract
In this study, [i]Mycobacterium tuberculosis[/i] complex was detected by BD ProbeTec ET system in 4716 respiratory and 167 nonrespiratory samples [mostly (98%) smear negative]. Sensitivity, specificity, positive and negative predictive values were 81.8%, 98.3, 85.1 and 97.9 for respiratory and 100%, 96.2, 64.7 and 100, for nonrespiratory samples, respectively. Among 149 (3.1%) ProbeTec DTB positive and culture negative samples, 72 (65 respiratory and seven nonrespiratory) (48.3%) were recovered from the patients who were evaluated as having TB infection. The system has been found as useful in early diagnosis of tuberculosis infection in association with the clinical, radiological and histopathological findings.

The diversity of [i]Mycobacterium tuberculosis[/i] clinical isolates, collected from a single hospital, was analyzed by ligation-mediated PCR techniques: FLiP and FLAP, and hybridization technique, IS[i]6110[/i]-RFL...
Non-invasive Diagnostic of Helicobacter pylori in Stools by Nested-qPCR
The aim of this study was to develop a non-invasive diagnostic test for the detection of Helicobacter pylori in stool samples from digestive symptomatic patients, using a new protocol of nested-qPCR. A total of 143 patie...
Identification and Localization of β-D-Glucosidase from Two Typical Oenococcus oeni Strains
β-D-glucosidase (βG) gene from [i]Oenococcus oeni [/i]SD-2a and 31MBR was cloned, sequenced and analyzed, also intracellular βG of the two strains was further localized. Results showed that βG gene of the two strains was...
Effect of Lyophilization on Survivability and Growth Kinetic of Trichoderma Strains Preserved on Various Agriculture By-Products
Growth kinetics of four Trichoderma strains was tested on lignocellulosic by-products in solid state fermentation (SSF). The strains were also analyzed for their survival rate and growth after lyophilization on these car...
