Identification of Mycobacterium tuberculosis and Rifampin Resistance in Pulmonary Extra-pulmonary Clinical Specimens Using the Gene Xpert MTB/RIF Assay

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 ...

Introduction: For a country with high Tuberculosis (TB) prevalence, infection of Severe Acute Respiratory Syndrome Coronavirus-2 (SARS-CoV-2) virus covert co-infection Mycobacterium Tuberculosis (MTB) is real concern.

We analyzed 57 publications devoted to study of genetic mechanisms formation drug resistance Mycobacterium tuberculosis bedaquiline, delamanid, pretomanid, linezolid, and clofazimine. Identification factors MTB make the basis search for new targets in development anti-tuberculosis drugs methods susceptibility testing.

introduction mycobacterium tuberculosis (mtb) is one of the most common causes of disseminated granulomatous diseases especially in developing countries. case presentation we present a patient who had an unusual type of tuberculosis who was misdiagnosed with some other common diseases such as infective endocarditis and collagen vascular diseases. pathological examination helped us to make decis...

pseudotumour is a benign inflammatory lesion. mycobacterial spindle cell pseudotumour (msp) is a rare pseudotumour. it is a benign proliferation of spindle-shaped histiocytes containing acid-fast mycobacterium, commonly reported in immunocompromised patients. msp is usually associated with mycobacterium avium complex (mac). here, we present the case of a 38-year-old gentleman with acquired immu...

OBJECTIVE This study represents an early attempt to determine the diversity of Mycobacterium tuberculosis in Egypt, particularly of drug-resistant strains. METHODS We characterized 45 Mycobacterium tuberculosis complex isolates from sputum samples of Egyptian patients with pulmonary tuberculosis, in order to establish a database of strain types and antimicrobial susceptibility patterns. RES...

ObjectiveTo evaluate he diagnostic performance of the Xpert Mycobacterium tuberculosis/Rifampin (MTB/RIF) assay in bronchoalveolar lavage fluid (BALF).MethodsWe retrospectively reviewed clinical data from 671 sputum-smear negative or sputum-scarce adult patients with suspected pulmonary tuberculosis (PTB) who had an MTB/RIF performed on BALF. The assay, smear microscopy (SM) and MTB culture was...

Mycobacterium tuberculosis (MTB) continues to plague humanity because of significant gaps in our understanding of MTB infection, including the nature of a protective versus pathological host response, why antimicrobial cure is so difficult, and the ineffectiveness of vaccination. The development of a zebrafish model, utilizing infection with the natural fish pathogen Mycobacterium marinum (Mm),...
