We evaluated a new line probe assay (LiPA) kit to identify Mycobacterium species and to detect mutations related to drug resistance in Mycobacterium tuberculosis. A total of 554 clinical isolates of Mycobacterium tuberculosis (n = 316), Mycobacterium avium (n = 71), Mycobacterium intracellulare (n = 51), Mycobacterium kansasii (n = 54), and other Mycobacterium species (n = 62) were tested with ...
BACKGROUND Immunosuppression and chronic lung disease are known risk factors for mycobacterial infection and might be expected to develop with an increased frequency in lung transplant recipients. We therefore sought to document the incidence and type of mycobacterial infections in a large lung transplant program. METHODS A retrospective review of 219 transplant procedures (60 single lung tra...
Several Mycobacterium-like organisms related to the Mycobacterium terrae complex have been isolated from clinical samples. In the clinical microbiology laboratory, partial 16S rRNA gene sequencing (approximately the first 500 bp) rather than full 16S rRNA gene sequencing is often used to identify Mycobacterium species. Partial 16S rRNA gene sequence analysis revealed 100 % similarity between 65...
Polypeptide Ags present in the culture filtrate of Mycobacterium tuberculosis were purified and evaluated for their ability to stimulate PBMC from purified protein derivative (PPD)-positive healthy donors. One such Ag, which elicited strong proliferation and IFN-gamma production, was further characterized. The N-terminal amino acid sequence of this polypeptide was determined and used to design ...
Usefulness of a new mycobacteriophage-based technique for rapid diagnosis of pulmonary tuberculosis.
A new mycobacteriophage-based technique (PhageTek MB) was compared with standard culture and staining techniques for diagnosis of pulmonary tuberculosis. A total of 2,048 respiratory specimens from 1,466 patients collected from February 2000 to March 2001 were studied by both (i) conventional methods (direct microscopic examination [auramine-rhodamine fluorochrome], and culture in BacT/ALERT 3D...
Mycobacterium avium complex (MAC) is the most common non-tuberculous mycobacterium (NTM) and causes different types of pulmonary diseases. While genomic transcriptomic analysis 104 (M. 104) has been extensive, little known about proteomics M. 104. We utilized technology to analyze changes in whole proteome during exponential stationary growth phases. found 12 dys-regulated proteins; up-regulate...
Objectives. Slowly growing mycobacteria (SGM) are prevalent worldwide and cause an extensive spectrum of diseases. Methods. In this study, the antimicrobial susceptibility of 33 reference strains of SGM to 19 antimicrobial agents was tested using a modified microdilution method. Results. Cefmetazole (32/33) and azithromycin (32/33) exhibited the highest antimicrobial activity, and dapsone (9/33...
The occurrence of Mycobacterium species in clinically healthy pet reptiles was studied in Italy during the period 2004-2006. The feces samples of 223 animals were examined bacteriologically. Thirty-seven strains were isolated, in particular from 13/18 (72.2%) ophidians, 13/134 (9.7%) saurians and 11/71 (15.5%) chelonians. The isolates were classified, after HPLC analysis of bromophenacyl esters...
Objective. Data on pulmonary tuberculosis (TB) caused by Mycobacterium tuberculosis (MTB) complex in Nigeria are limited. We investigated species of MTB complex in TB cases from northern Nigeria. Methods. New TB suspects were enrolled, screened for HIV and their sputum samples were cultured after routine microscopy. Genotypes MTBC and MTBDRplus were used to characterize the MTB complex species ...
Background: Leprosy is a chronic disease, caused by the bacterium Mycobacterium leprae. It characterized decrease or loss of thermal, pain and tactile sensitivity, as well muscle strength.
