In view of recent reports of contamination of the fibreoptic bronchoscope by tuberculous and non-tuberculous mycobacteria, we evaluated the disinfecting properties of aqueous glutaraldehyde (Cidex) and an iodophor (Prepodyne) against Mycobacterium tuberculosis and M gordonae. We found that a 15 minute disinfection procedure with either agent, coupled with initial vigorous mechanical cleaning of...

Mycobacteria of feline importance include (1) obligate pathogens (tuberculosis), (2) mycobacteria that are difficult to grow, so the environmental niche is unknown (feline leprosy syndrome), and (3) facultative pathogenic opportunistic saprophytes (non-tuberculous mycobacteriosis). Most cats present with cutaneous disease, although some have systemic involvement. Diagnosis is challenging becaus...

Mycobacteria represent a class of powerful pathogens, including those causing tuberculosis and leprosy, which continue to be worldwide health challenges. In the last 20 years, an abundance of non-coding, small RNAs (sRNAs) have been discovered in model bacteria and gained significant attention as regulators of cellular responses, including pathogenesis. Naturally, a search in mycobacteria follo...

HIGHLIGHTS A multiplex PCR to identifying mycobacteria of medical interest was evaluated. Mycobacterium tuberculosis can be differentiated from other with the assay. The assay showed high sensitivity and specificity in detecting M. avium complex.

Early diagnostics of resistance to fluoroquinolones facilitates early start adequate therapy and increases the chance a favorable outcome tuberculosis. Application genetic methods permits obtain within 1–2 days results Mycobacterium tuberculosis detection anti-tuberculosis drugs, unlike classical requiring up 1−2 month. The aim study is develop method for M. identification point mutations in co...

Metabolic versatility has been increasingly recognized as a major virulence mechanism that enables Mycobacterium tuberculosis to persist in many microenvironments encountered in its host. Glucose is one of the most abundant carbon sources that is exploited by many pathogenic bacteria in the human host. M. tuberculosis has an intact glycolytic pathway that is highly conserved in all clinical iso...

Mycobacteria that cause tuberculosis in animals and humans belong to the Mycobacterium tuberculosis complex. Techniques for conventional diagnosis are time-consuming and do not differentiate between different strains belonging to the M. tuberculosis complex. The aim of this study was to evaluate a multiplex PCR assay applicable to mycobacteria in culture with the capacity to differentiate diffe...

Tuberculosis is one of the grand old diseases and among the top burdened diseases of the world. Most Mycobacteria are environmental saprophytes except Mycobacterium tuberculosis and Mycobacterium leprae, which are obligate pathogens. However, several studies indicate that the selection of the pathogens in an ever changing environment do occur by a variety of deletion mutations over time. Mycoba...

The Non-Tuberculous Mycobacteria (NTM),whose habitat the environment has acquired importance in the last years because of the immunosupressed patients, infected HIV ,and also in develop countries that have managed to eradicated the bovine tuberculosis. Where it has been verified that certain NTM interfere in the diagnosis of tuberculosis when it is applied to the delayed hypersensitivity test w...
