the ability of proteus mirabilis to sense surfaces and regulate virulence gene expression involves flil, a flagellar basal body protein.proteus mirabilis is a urinary tract pathogen that differentiates from a short swimmer cell to an elongated, highly flagellated swarmer cell. swarmer cell differentiation parallels an increased expression of several virulence factors, suggesting that both processes are controlled by the same signal. the molecular nature of this signal is not known but is hypothesized to involve the inhibition of flagellar rotation. in this study, data are presented supporting the idea that conditions inhibiting ...200516166542
toxicological effect of indole and its azo dye derivatives on some microorganisms under aerobic conditions.azo dyes are ubiquitous commercial chemicals that present unique environmental problems. the azo dyes in particular can undergo natural anaerobic degradation to potentially carcinogenic amines. they pose a major problem for water-treatment plants downstream. one strategy to remidate polluted surface contaminants is to make use of the degradative capacity of bacteria rather than using destructive chemical reactions. therefore, pathogenic and non-pathogenic microorganisms namely; bacillus thuringi ...200616165191
