Abstract:
We evaluated the BACTEC MGIT 960 system, which is a fully automated, noninvasive system for the growth and detection of mycobacteria with a capacity to incubate and continuously monitor 960 7-ml culture tubes. We studied 3,330 specimens, 2,210 respiratory and 1,120 nonrespiratory specimens, collected from 2,346 patients treated at six sites. Processed specimens were inoculated into the BACTEC MGIT 960 and BACTEC 460 TB systems, as well as onto Lowenstein-Jensen slants and Middlebrook 7H11/7H11 selective plates. From all culture systems, a total of 362 isolates of mycobacteria were recovered; t

Abstract:
ABSTRACTPyrazinamide (PZA) is a potent first-line agent for the treatment of tuberculosis (TB) with activity also against a significant part of drug-resistantMycobacterium tuberculosisstrains. Since PZA is active only at acid pH, testing for susceptibility to PZA is difficult and insufficiently reproducible. The recommended critical concentration for PZA susceptibility (MIC, 100 mg/liter) used in the Bactec systems (460 and MGIT 960) has not been critically evaluated against wild-type MIC distributions in clinical isolates ofMycobacterium tuberculosis.

In a large multicenter study involving six major study sites in the United States, Canada, and Europe, the susceptibilities of 272Mycobacterium tuberculosis strains to classical second-line antituberculosis (anti-TB) drugs (capreomycin, cycloserine, ethionamide, and kanamycin) and newer compounds (amikacin, clofazimine, ofloxacin, and rifabutin) were determined by the radiometric BACTEC 460 procedure and the conventional proportion method on Middlebrook 7H10 agar. Previously established critical concentrations for classical second-line anti-TB drugs were compared with several concentrations in

Abstract:
Background and Objectives: Tuberculosis (TB) is one of the most common infectious diseases in developing countries. The resistance of the causative agent, Mycobacterium tuberculosis, to two or more first-line anti-TB drugs results in multidrug-resistant (MDR) TB, posing a serious challenge to the control of TB worldwide. This study was designed to determine the changes in drug resistance over time in TB strains isolated from patients in all departments of Uludağ University Hospital in western Türkiye. Materials and Methods: We retrospectively analyzed 104,598 clinical samples sent to our labor

Abstract:
In the microbiological laboratory CAPD fluid analysis is an unstandardized and sometimes a labor intensive procedure. This pilot study was set up to demonstrate the value of in-place technology -the Bactec 460 blood culture system, in reducing the work-load. Our results indicate that it is at least as effective as other, more tedious conventional methods. Since its introduction, continuous ambulatory peritoneal dialysis (CAPD) has proved to be a major advance in the management of end-stage renal disease (I). Despite refinements in technique over the years leading to more widespread use of CAPD

Abstract:
ABSTRACT The postantibiotic effects (PAEs) of antimycobacterial agents determined with a BACTEC TB-460 instrument (CO2 production) and by a traditional viable-count method against Mycobacterium avium complex (MAC) were not significantly different (P > 0.05). The longest PAEs following a 2-h exposure to 2× the MIC were induced by amikacin (10.3 h), rifampin (9.7 h), and rifabutin (9.5 h), while the shortest PAEs resulted from clofazimine (1.7 h) and ethambutol (1.1 h) exposure. CO2 generation is a valid and efficient means of determining in vitro PAEs against MAC.

In response to the need for rapid, inexpensive, high-throughput assays for antimycobacterial drug screening, a microplate-based assay which uses Alamar blue reagent for determination of growth was evaluated. MICs of 30 antimicrobial agents against Mycobacterium tuberculosis H37Rv, M. tuberculosis H37Ra, and Mycobacterium avium were determined in the microplate Alamar blue assay (MABA) with both visual and fluorometric readings and compared to MICs determined in the BACTEC 460 system.

ABSTRACT An optimal assay for high-throughput screening for new antituberculosis agents would combine the microplate format and low cost of firefly luciferase reporter assays and redox dyes with the ease of kinetic monitoring inherent in the BACTEC system. The green fluorescent protein (GFP) of the jellyfish Aequorea victoria is a useful reporter molecule which requires neither substrates nor cofactors due to the intrinsically fluorescent nature of the protein. The gene encoding a red-shifted, higher-intensity GFP variant was introduced by electroporation into Mycobacterium tuberculosis H37Ra
