objective the aim of this study was to compare the sensitivity and specificity of acid fast and auramine-rhodamine staining and multiplex pcr for the detection of mycobacterium tuberculosiscomplex and non tuberculosis mycobacteria on formalin fixed paraffin embedded tissues (ffpe) materials and methods forty cases of ffpe pleural and bronchial tissue with chronic granulomatous inflammation and ...

introduction mycobacterium tuberculosis complex (mtbc) are causative agents of human and animal tuberculosis.differentiation of mtbc members is required for appropriate treatment of individual patients and for epidemiologicalpurposes and reduction in drug resistances. material and methods 1345 patients were collected with clinical suspicions of tuberculosis who referred to the health care cente...

BACKGROUND Mycobacterium tuberculosis, the causative agent of tuberculosis, still represents a major public health threat in many countries. Bioluminescence, the production of light by luciferase-catalyzed reactions, is a versatile reporter technology with multiple applications both in vitro and in vivo. In vivo bioluminescence imaging (BLI) represents one of its most outstanding uses by allowi...

Mycobacterium tuberculosis infections result in a spectrum of clinical outcomes, and frequently the infection persists in a latent, clinically asymptomatic state. The within-host bacterial population is likely to be heterogeneous, and it is thought that persistent mycobacteria arise from a small population of viable, but non-replicating (VBNR) cells. These are likely to be antibiotic tolerant a...

The article presents the results of allergic and bacteriological studies cattle from a tuberculosis-free farm. presence reacting to an allergen atypical mycobacteria was established in three simultaneous tests during 2019–2020. Based on obtained, causative agent tuberculosis were not isolated examination biological material animals slaughtered for diagnostic purposes (n = 17), as well soil 5) s...

three tuberculous, twenty-one non-tuberculous mycobacterial (ntm) reference strains and seventy two isolates classified by biochemical tests were shown to produce specific sets of dna fragments in a polymerase chain reaction with single universal primer (up-pcr). a rather wide limit of tolerance for variations in procedure of pcr mixture preparation and thermocycling parameters was found. there...

Introduction: In HIV-associated tuberculosis cases, identifying nontuberculous Mycobacteria (NTM) from clinical samples has become essential regarding patients’ treatment and prognosis. This study aims to determine the prevalence of different Mycobacteria species from immunocompromised and immunocompetent patients with suspected tuberculosis attending a tertiary care hospital in Kolkata, India....

Allergic examination using PPD-tuberculins is the main method of life-time tuberculosis diagnostics in farm animals and poultry. However, it known about a decrease diagnostic value allergic reactions after irradiation animals, occurrence non-specific, pseudo-allergic reactions. One reasons for manifestation non-specific may be autosensitisation (autoallergisation) body by breakdown products per...
