Mechanisms Determining Bacterial Biofilm Resistance to Antimicrobial Factors
In most natural environments, the process of bacterial surface association is prevailing cells lifestyle. The tendency of bacteria to colonize solid materials is advantageous from an ecological standpoint. This mechanism allows bacteria the colonization of a nutritionally favorable new niche and encouraging symbiotic relationships between the cells. Sessile mode of growth provides also some lev...
متن کاملIdentification of Factors that Influence Screening for Bacterial Blight Resistance
Inoculation of plant pathogenic bacteria in field plots has been improved by the use of organosilicone surfactants. Factors, such as cultivars, number of applications, crop stage, plant density, concentration of bacteria, and irrigation application method (overhead spray versus drop hoses), that may affect field screening of cotton cultivars for resistance to bacterial blight caused by Xanthomo...
متن کاملRNA-dependent lipid remodeling by bacterial multiple peptide resistance factors.
Multiple peptide resistance (MprF) virulence factors control cellular permeability to cationic antibiotics by aminoacylating inner membrane lipids. It has been shown previously that one class of MprF can use Lys-tRNA(Lys) to modify phosphatidylglycerol (PG), but the mechanism of recognition and possible role of other MprFs are unknown. Here, we used an in vitro reconstituted lipid aminoacylatio...
متن کاملBacterial enterotoxins are associated with resistance to colon cancer.
One half million patients suffer from colorectal cancer in industrialized nations, yet this disease exhibits a low incidence in under-developed countries. This geographic imbalance suggests an environmental contribution to the resistance of endemic populations to intestinal neoplasia. A common epidemiological characteristic of these colon cancer-spared regions is the prevalence of enterotoxigen...
متن کاملPredicting bacterial fitness cost associated with drug resistance.
OBJECTIVES It has been proposed that antimicrobial resistance could be associated with a fitness cost in bacteria, which is often determined by competition experiments between isogenic strains (wild-type and mutant). However, this conventional approach is time consuming and labour intensive. An alternative method was developed to assess the fitness cost in drug-resistant bacteria. METHODS Tim...
