BACKGROUND Tubercle bacilli are thought to persist in a dormant state during latent tuberculosis (TB) infection. Although little is known about the host factors that induce and maintain Mycobacterium tuberculosis (M. tb) within latent lesions, O(2) depletion, nutrient limitation and acidification are some of the stresses implicated in bacterial dormancy(More)
BACKGROUND The DevR(DosR) regulon is implicated in hypoxic adaptation and virulence of Mycobacterium tuberculosis. The present study was designed to decipher the impact of perturbation in DevR-mediated signaling on these properties. METHODOLOGY/PRINCIPAL FINDINGS M. tb complemented (Comp) strains expressing different levels of DevR were constructed in(More)
DevR is a key regulator of the dormancy response in Mycobacterium tuberculosis (M. tb). Using DevR as bait to screen a phage display library, a peptide, DevRS1, was obtained. DevRS1 inhibited DevR-regulated transcription and survival of nonreplicating tubercle bacilli in a hypoxia model of dormancy. DevRS1 peptide-mediated inhibition demonstrates the(More)
Two-component systems have emerged as compelling targets for antibacterial drug design for a number of reasons including the distinct histidine phosphorylation property of their constituent sensor kinases. The DevR-DevS/DosT two component system of Mycobacterium tuberculosis (M. tb) is essential for survival under hypoxia, a stress associated with dormancy(More)
Abstrat This paper presents the optimization of various benchmark functions using Genetic Algorithm. The comparative study is performed using benchmark functions. This main purpose of this paper is to find a comparative study of various encoding schemes, selection methods, scaling mechanism, crossover and mutation operators. This includes recording the(More)
This paper presents a review on the major benchmarking functions used for performance control of Genetic Algorithms (GAs). The difficulties of providing benchmarking of Genetic algorithms that is meaningful and logistically viable. To be meaningful the benchmarking test must give a fair comparison that is free, as far as possible, from biases that favor one(More)
