Evaluation of the semiautomated Abbott LCx Mycobacterium tuberculosis assay for direct detection of Mycobacterium tuberculosis in respiratory specimens
TLDR
The LCx M. tuberculosis Assay has proved to have an acceptable sensitivity and a high specificity in detecting M.culosis and has the potential of reducing the diagnosis time to an 8-h working day.
Comparative Evaluation of Initial and New Versions of the Gen-Probe Amplified Mycobacterium Tuberculosis Direct Test for Direct Detection of Mycobacterium tuberculosis in Respiratory and
TLDR
It was concluded that although both nucleic acid amplification methods are rapid, sensitive, and specific for the detection of M. tuberculosis complex in all types of clinical samples, AMTDT 2 appeared to be more sensitive than AM TDT 1 when applied to smear-negative specimens.
Evaluation of a commercial probe assay for detection of rifampin resistance inMycobacterium tuberculosis directly from respiratory and nonrespiratory clinical samples
TLDR
The Inno-Line Probe Assay is a rapid, useful method for detecting the presence of Mycobacterium tuberculosis complex and its resistance to rifampin directly from clinical specimens and culture and may constitute an important tool for the control of tuberculosis.
Rapid Diagnosis of Extrapulmonary Tuberculosis by Ligase Chain Reaction Amplification
TLDR
The results demonstrate that the LCx M. tuberculosis Assay will provide rapid and valuable information for the diagnosis of extrapulmonary tuberculosis.
Comparison of a Nonradiometric System with Bactec 12B and Culture on Egg-Based Media for Recovery of Mycobacteria from Clinical Specimens
TLDR
MB/BacT is a reliable, nonradiometric, less labor-intensive alternative to Bactec 12B for recovery of mycobacteria, but, as with other liquid culture methods, it should be used in combination with a solid medium, not on its own.
Comparative evaluation of two commercial assays for direct detection ofMycobacterium tuberculosis in respiratory specimens
TLDR
It is concluded that although both nucleic acid amplification methods are rapid and specific for the detection of Mycobacterium tuberculosis complex in respiratory specimens, the Cobas Amplicor MTB Test appears to be slightly more sensitive when smear negative specimens are investigated.
Presence and antimicrobial profile of gram-negative facultative anaerobe rods in patients with chronic periodontitis and gingivitis.
TLDR
The existence of a high frequency of enterobacteria in patients with chronic periodontitis and gingivitis shows that periodontologists should pay greater attention to prevention protocols, and develop mechanical and antimicrobial therapies in which antimicrobial susceptibility profile reports should be considered as part of periodontal treatment.
Comparative Study of Bacteremias Caused byEnterococcus spp. with and without High-Level Resistance to Gentamicin
TLDR
HLRG did not influence the prognosis for patients with enterococcal bacteremia, and Hemodynamic compromise, inappropriate antimicrobial therapy, and mechanical ventilation were revealed in the multivariate analysis to be the independent risk factors for mortality.
Detection of mycobacterium tuberculosis in paraffin-embedded pleural biopsy specimens by commercial ribosomal RNA and DNA amplification kits.
TLDR
Amplification techniques are useful in archival PEB tissues, providing additional diagnoses beyond culturing, although the sensitivity should be improved, possibly by standardizing protocols.
Antimicrobial potential of extracts from Stevia rebaudiana leaves against bacteria of importance in dental caries.
TLDR
The results suggest that inhibition zones with a hexane extract are similar to those obtained with ethanol and methanol, but the minimal inhibitory concentration is lower, and for the four Lactobacillus species, the inhibition zones obtained were somewhat larger with ethyl acetate and chloroform extracts, suggesting they were the most susceptible microorganisms.
