| Inhibition of escherichia coli and proteus mirabilis adhesion and biofilm formation on medical grade silicone surface. | Silicone has been utilized extensively for biomedical devices due to its excellent biocompatibility and biodurability properties. However, its surface is easily colonized by bacteria which will increase the probability of nosocomial infection. In the present work, a hydrophilic antimicrobial carboxymethyl chitosan (CMCS) layer has been grafted on medical grade silicone surface pre-treated with polydopamine (PDA). The increase in hydrophilicity was confirmed from contact angle measurement. Bacter ... | 2012 | 21956834 |

| influence of quorum sensing signal molecules on biofilm formation in proteus mirabilis o18. | the influence of basis of quorum sensing molecules on proteus strains is much less known as compared to pseudomonas or escherichia. we have previously shown that a series of acylated homoserine lactones (acyl-hsl) does not influence the ureolytic, proteolytic, or hemolytic abilities, and that the swarming motility of proteus mirabilis rods is strain specific. the aim of the presented study was to find out if the presence of a series of acyl-hsl influences biofilm formation of p. mirabilis labora ... | 2011 | 22198843 |
| multiple origins of endosymbiosis within the enterobacteriaceae (gamma-proteobacteria): convergence of complex phylogenetic approaches. | abstract: background: the bacterial family enterobacteriaceae gave rise to a variety of symbiotic forms, from the loosely associated commensals, often designated as secondary (s) symbionts, to obligate mutualists, called primary (p) symbionts. determination of the evolutionary processes behind this phenomenon has long been hampered by the unreliability of phylogenetic reconstructions within this group of bacteria. the main reasons have been the absence of sufficient data, the highly derived nat ... | 2011 | 22201529 |
