To better understand the biology and the virulence determinants of the two major mycobacterial human pathogens Mycobacterium tuberculosis and Mycobacterium leprae, their genome sequences have been determined recently. In silico comparisons revealed that am ...
Mycobacterium tuberculosis, the causative agent of tuberculosis, possesses a class Ib ribonucleotide reductase (RNR), encoded by the nrdE and nrdF2 genes, in addition to a putative class II RNR, encoded by nrdZ. In this study we probed the relative contrib ...
Mycobacterium tuberculosis has two genes for ferric uptake regulator orthologues, one of which, furA, is situated immediately upstream of katG encoding catalase-peroxidase, a major virulence factor that also activates the prodrug isoniazid. This associatio ...
Mycobacterium tuberculosis, the scourge of humanity, is one of the most successful and scientifically challenging pathogens of all time. To catalyze the conception of new prophylactic and therapeutic interventions against tuberculosis, and to enhance our u ...
Although the virulences and host ranges differ among members of the Mycobacterium tuberculosis complex (TBC; M. tuberculosis, M. africanum, M. canettii, M. microti, M. bovis, and M. bovis BCG), commercially available molecular assays cannot differentiate t ...
Pathogenetic processes that facilitate the entry, replication, and persistence of Mycobacterium tuberculosis (MTB) in the mammalian host likely include the regulated expression of specific sets of genes at different stages of infection. Identification of g ...
Mycobacterium bovis is the causative agent of tuberculosis in a range of animal species and man, with worldwide annual losses to agriculture of $3 billion. The human burden of tuberculosis caused by the bovine tubercle bacillus is still largely unknown. M. ...
The success of Mycobacterium tuberculosis as a pathogen is largely attributable to its ability to persist in host tissues, where drugs that are rapidly bactericidal in vitro require prolonged administration to achieve comparable effects. Latency is a frequ ...
The distribution of 20 variable regions resulting from insertion-deletion events in the genomes of the tubercle bacilli has been evaluated in a total of 100 strains of Mycobacterium tuberculosis, Mycobacterium africanum, Mycobacterium canettii, Mycobacteri ...
During the last decade, there has been a marked increase in the number of gravity of tuberculosis cases both in developing countries and in industrialized nations. This is, in part, due to the acquired immune deficiency syndrome (AIDS) pandemic, but global ...
