Spondiasmombin is a widely cultivated edible plant used in folkloric medicine for the treatment of severe cough and other respiratory disorders. This study evaluated the anti tubercular property of the stem of S. mombin against Mycobacterium tuberculosis (H37Rv and EJA-2011) using agar proportion assay on Lowenstein-Jensen medium. Four new compounds were isolated from the stem of Spondiasmombin...

New and reemerging infectious diseases will continue to pose serious global health threats well into the 21st century and according to the World Health Organization report, these are still the leading cause of death among humans worldwide. Among infectious diseases, tuberculosis claims approximately 2 million deaths per year worldwide. Also, agents that reduce the duration and complexity of the...

The antimicrobial action of a number of non-antibiotic drugs has been demonstrated in recent years, for example the antimycobacterial activity associated with the phenothiazine neuroleptic class. However, as with other classes of non-antibiotics, such activity may be traced back to common precursor structures such as the phenothiazinium dye, methylene blue. While the rising tide of antimicrobia...

A number of antimycobacterial agents were evaluated with respect to their bacteriostatic activity (growth inhibition) versus the bactericidal activity against a clinical isolate of Mycobacterium avium (Mycobacterium avium complex [MAC] strain 101) in relation to the time of exposure and the growth phase of the mycobacteria. In terms of growth inhibition the MAC in the active phase of growth was...

The comparative molecular field analysis (CoMFA) based on three dimensional quantitative structure–activity relationship (3D-QSAR) studies were carried out employing, natural terpenes as potent antimycobacterial agents. The best prediction were obtained with a CoMFA standard model (q2 = 0.569, r2 = 0.999) using steric, electrostatic, hydrophobic and hydrogen bond donor fields. In the current st...

The postantibiotic effects (PAEs) of seven antimycobacterial agents, tested at their respective peak concentrations in serum alone and in different combinations, against Mycobacterium tuberculosis ATCC 27294 were studied with a radiometric culture system in parallel with the viable count method. Rifampin gave the longest PAE (67.8 h) among the drugs used alone, and combinations of first-line dr...

introduction many studies have shown epidemiological links between strains isolated in tap water, and those isolated from patients. molecular methods linked to pcr are more reliable and faster for identification of             non- tuberculous mycobacteria(ntm). in this study molecular methods were used for identification and typing of ntm. materials and methods five hundred ml of 85 water samp...
