The resistance and pathogenesis of bacteria could be related to their ability to sense and respond to population density, termed quorum sensing (QS). Inhibition of the QS system is considered as a novel strategy for the development of antipathogenic agents, especially for combating drug-resistant bacterial infections. In the present study, the anti-QS activity of Onion peel ethylacetate fractio...
Natural products produced by microorganisms have been an important source of new substances and lead compounds for the pharmaceutical industry. Chromobacterium violaceum is a Gram-negative β-proteobacterium, abundant in water and soil in tropical and subtropical regions and it produces violacein, a pigment that has shown great pharmaceutical potential. Crude extracts of five Brazilian isolates ...
In the new antibiotic era, exponential increase in multiresistant bacterial strains has become main global health problem. Many researchers have focused their efforts on exploring novel or combined strategies for combating resistance. Good knowledge of molecular mechanisms resistance and virulence factors as key targets provides us with a good basis resolving One particularly attractive promisi...
A gene cluster responsible for the biosynthesis of anticancer agent FK228 has been identified, cloned, and partially characterized in Chromobacterium violaceum no. 968. First, a genome-scanning approach was applied to identify three distinctive C. violaceum no. 968 genomic DNA clones that code for portions of nonribosomal peptide synthetase and polyketide synthase. Next, a gene replacement syst...
