Lysis filtration (LyF) was compared with BACTEC PAEDS PLUS in estimating the prevalence of, and sensitivity for, detection of odontogenic bacteremia. Both real bacteremia and simulated bacteremia (seeded blood or saline samples) were assessed to determine the validity of LyF in estimating bacteremia. The simulated bacteremia was also used to assess the reliability of LyF to estimate intensity o...

Introduction. Mycobacterium tuberculosis is the causative agent of tuberculosis. Drug susceptibility testing performed by phenotypic and molecular tests. Commonly used for drug automated BACTEC system in a liquid culture medium. line probe tests was introduced almost 15 years ago. Recently whole genome sequencing (WGS) analysis M. strains demonstrated that genotyping drug-resistance could be ac...

BACTEC 13A medium (Johnston Laboratories, Towson, Md.) was compared with Isolator (Du Pont Co., Wilmington, Del.) concentrate for sensitivity, speed, and technical ease of isolation of mycobacteria from paired patient blood samples. Of 72 positive cultures, 63 were positive by both systems. Five positive cultures were detected by BACTEC 13A medium alone, and four were detected by Isolator alone...

The objectives of this study were to investigate the origin of highly discordant rifampin (rifampicin) (RMP) drug susceptibility test results obtained for Mycobacterium tuberculosis strains during proficiency testing. Nine Supra-National Tuberculosis Reference Laboratories tested the RMP susceptibilities of 19 selected M. tuberculosis strains, using standard culture-based methods. The strains w...

Fifty isolates of Mycobacterium tuberculosis complex were tested for susceptibility to pyrazinamide (PZA) by the ESP (Trek Diagnostic Systems, Westlake, Ohio) and BACTEC (BD Biosciences, Sparks, Md.) test systems. Initial results showed concordance for 48 of the isolates. On retest, the two discordant isolates were resolved in favor of the ESP system. The ESP Myco susceptibility test system gen...

A colorimetric, microplate-based Alamar Blue assay (MABA) method was used to determine the MICs of isoniazid (INH), rifampin, streptomycin (SM), and ethambutol (EMB) for 34 Peruvian Mycobacterium tuberculosis isolates (including both pansensitive and multidrug-resistant strains) and the H37Rv strain by using bacterial suspensions prepared directly from solid media. Results for all isolates were...

Purpose: Since standard microbiological methods (use of solid media) have low sensitivity to detect aetiological agents in vitreous aspirates in infectious endophthalmitis, a comparative study was undertaken to determine sensitivity of BACTEC Peds Plus F broth for isolation of these aetiological agentsMethods: Four hundred and eighty three consecutive vitreous aspirates from clinically diagnose...

Detection and identification of anaerobic bacteria in blood cultures (BC) is a well-recognized challenge in clinical microbiology. We studied 100 clinical anaerobic BC isolates to evaluate the performance of BacT/ALERT-FN, -FN Plus (BioMérieux), BACTEC-Plus and -Lytic (Becton Dickinson BioSciences) BC bottles in detection and time to detection (TTD) of anaerobic bacteria. BACTEC Lytic had highe...
