Background: Diabetes is an important metabolic disease with myriad manifestations and complications, affecting many people. Cutaneous infections impact numerous diabetic patients. Among different bacterial infections in diabetic patients, the infections caused by mycobacteria other than Mycobacterium tuberculosis (MOTT) eventuate in complications owing to the paucity of accurate detection...

Background: Mycobacterium tuberculosis is a major cause of mortality and morbidity worldwide. Infection with this bacterium is known to induce the development of autoantibodies of which a few are also known to be diagnostic markers for some other diseases. Antineutrophil Cytoplasmic Antibodies (ANCA's) are among those autoantibodies used in clinical setting for diagnosing systemic vasculitic sy...

Eleven fatty acid analogues incorporating four-membered carbocycles (cyclobutenes, cyclobutanes, cyclobutanones, and cyclobutanols) were investigated for the ability to inhibit the growth of Mycobacterium smegmatis (Msm) and Mycobacterium tuberculosis (Mtb). A number of the analogues displayed inhibitory activity against both mycobacterial species in minimal media. Several of the molecules disp...

Nine unidentified marine sponges from Bunaken Island waters in Manado Indonesia were observed on anti-tuberculosis (TB) against non-pathogenic Mycobacterium smegmatis NBRC 3207 and it was found that the ethanol crude extracts ODS fractions of these inhibited growth bacteria M. smegmatis. Sponge SP.323 is most inhibiting showed Intermediate (I) activity with inhibition zones 9, 11, 8 mm/disk at ...

A series of bedaquiline analogs containing H-bond donors were designed as anti-Mycobacterium tuberculosis drugs. A pair of diastereoisomers (R/S- and S/S-isomers) was selected from these designed compounds for synthetic and stereochemical research. The title compounds were synthesized from chiral precursors for the first time and the absolute configurations (ACs) were determined by electronic c...

We identified a di-substituted triazolopyrimidine with anti-tubercular activity against Mycobacterium tuberculosis. Three segments of the scaffold were examined rationally to establish a structure-activity relationship with the goal of improving potency and maintaining good physicochemical properties. A number of compounds displayed sub-micromolar activity against Mycobacterium tuberculosis wit...

Exposure to Mycobacterium tuberculosis produces varied early outcomes, ranging from resistance to infection to progressive disease. Here we report results from a forward genetic screen in zebrafish larvae that identify multiple mutant classes with distinct patterns of innate susceptibility to Mycobacterium marinum. A hypersusceptible mutant maps to the lta4h locus encoding leukotriene A(4) hydr...

The mannosylated lipoarabinomanan (ManLAM) from mycobacterial species possesses strong anti-apoptotic action. Here we examined the ability of ManLAM isolated from Mycobacterium tuberculosis H37Rv to alter expression profiles of apoptosis-related genes in mouse macrophages infected with Mycobacterium bovis BCG Danish strain. ManLAM suppressed BCG-induced apoptosis and activities of caspase-1, -3...

Monospecific antibodies have been successfully utilized in antigen detection, which is better indicator of active infection. Mycobacterium tuberculosis excretory secretory (M tb ES) antigens such as ES 31, ES 41 and ES 43 (31 kDa, 41 kDa and 43 kDa protein, respectively) have been shown to be present in Mycobacterium tuberculosis H37Ra culture filtrate and are of diagnostic interest. To study t...
