The search for drugs that can kill replicating and nonreplicating Mycobacterium tuberculosis faces practical bottlenecks. Measurement of CFU and discrimination of bacteriostatic from bactericidal activity are costly in compounds, supplies, labor, and time. Testing compounds against M. tuberculosis under conditions that prevent the replication of M. tuberculosis often involves a second phase of ...
We tested a new method for detecting drug-resistant strains of Mycobacterium tuberculosis that uses a TM4 mycobacteriophage phAE87::hsp60-EGFP (EGFP-phage) engineered to contain the gene encoding enhanced green fluorescent protein (EGFP). After promising results in preliminary studies, the EGFP-phage was used to detect isoniazid (INH), rifampin (RIF), and streptomycin (STR) resistance in 155 st...
BACKGROUND Tuberculosis, caused by Mycobacterium tuberculosis (MTB), is the most notified disease in the world. Development of resistance to first line drugs by MTB is a public health concern. As a result, there is the search for new and novel sources of antimycobacterial drugs for example from medicinal plants. In this study we determined the in vitro antimycobacterial activity of n-Hexane sub...
We describe here a new microquantification method of l-phenylalanine concentration in an extract from a dried blood spot by using the diaphorase-resazurin system. To miniaturize the fluorometric enzymatic microplate assay for the diagnosis of phenylketonuria, an enzyme chip immobilized with His-tag fused phenylalanine dehydrogenase (PheDH) was developed. His-tag fused PheDH was immobilized on t...
The Cover Feature illustrates deactivation and regeneration of nickel catalyst in a microchannel-coupled-millireactor. During continuous operation, millireactors show strong catalytic activity for reduction resazurin p-nitrophenol. complete magnetic Ni particles is found to be an instantaneous process. Regeneration Nickel has been achieved by flowing water air. design Debashis Panda. More infor...
