| identification of the domains of urer, an arac-like transcriptional regulator of the urease gene cluster in proteus mirabilis. | proteus mirabilis urease catalyzes the hydrolysis of urea to co(2) and nh(3), resulting in urinary stone formation in individuals with complicated urinary tract infections. urer, a member of the arac family, activates transcription of the genes encoding urease enzyme subunits and accessory proteins, uredabcefg, as well as its own transcription in the presence of urea. based on sequence homology with arac, we hypothesized that urer contains both a dimerization domain and a dna-binding domain. a t ... | 2001 | 11443087 |
| urinary tract infections in women. | urinary tract infections (utis) are the most common infections seen in the hospital setting, and the second most common infections seen in the general population. due to women's anatomy, utis are especially problematic for them, and up to one-third of all women will experience a uti at some point during their lifetimes. appropriate treatment of a uti requires accurate classification that includes infection site, complexity of the infection, and the likelihood of recurrence. the predominant patho ... | 2001 | 11442991 |

| a putative insect intracellular endosymbiont stem clade, within the enterobacteriaceae, infered from phylogenetic analysis based on a heterogeneous model of dna evolution. | insect intracellular symbiotic bacteria (intracellular endosymbionts, or endocytobionts) were positioned within the gamma 3-proteobacteria using a non-homogeneous model of dna evolution, allowing for rate variability among sites, for gc content heterogeneity among sequences, and applied to a maximum likelihood framework. most of them were found to be closely related within the enterobacteriaceae family, located between proteus and yersinia. these results suggest that such a bacterial group might ... | 2001 | 11411291 |
| biotransformation of crotonobetaine to l(-)-carnitine in proteus sp. | two proteins, component i (ci) and component ii (cii), catalyze the biotransformation of crotonobetaine to l(-)-carnitine in proteus sp. ci was purified to electrophoretic homogeneity from cell-free extracts of proteus sp. the n-terminal amino acid sequence of ci showed high similarity (80%) to the caib gene product from escherichia coli o44k74, which encodes the l(-)-carnitine dehydratase. ci alone was unable to convert crotonobetaine into l(-)-carnitine even in the presence of the cosubstrates ... | 2001 | 11409545 |
| tissue antioxidant capacity and bacterial translocation under total parenteral nutrition. | alterations in the antioxidative system have been observed during total parenteral nutrition (tpn). light exposure or changes in the composition of tpn formulas may affect this system. bacterial translocation (bt) is frequent under tpn and may be related to oxidative status. the aim of this study was to determine the adverse effects of standard and glutamine-enriched tpn, with or without light exposure, on oxidative status (liver and kidney-reduced glutathione, gsh) and its relationship to bt. t ... | 2001 | 11409162 |
| identification of proteus mirabilis mutants with increased sensitivity to antimicrobial peptides. | antimicrobial peptides (aps) are important components of the innate defenses of animals, plants, and microorganisms. however, some bacterial pathogens are resistant to the action of aps. for example, proteus mirabilis is highly resistant to the action of aps, such as polymyxin b (pm), protegrin, and the synthetic protegrin analog ib-367. to better understand this resistance, a transposon mutagenesis approach was used to generate p. mirabilis mutants sensitive to aps. four unique pm-sensitive mut ... | 2001 | 11408219 |

| theory of periodic swarming of bacteria: application to proteus mirabilis. | the periodic swarming of bacteria is one of the simplest examples for pattern formation produced by the self-organized collective behavior of a large number of organisms. in the spectacular colonies of proteus mirabilis (the most common species exhibiting this type of growth), a series of concentric rings are developed as the bacteria multiply and swarm following a scenario that periodically repeats itself. we have developed a theoretical description for this process in order to obtain a deeper ... | 2001 | 11308686 |
| analytic model for ring pattern formation by bacterial swarmers. | we analyze a model proposed by medvedev, kaper, and kopell (the mkk model) for ring formation in two-dimensional bacterial colonies of proteus mirabilis. we correct the model to formally include a feature crucial of the ring generation mechanism: a bacterial density threshold to the nonlinear diffusivity of the mkk model. we numerically integrate the model equations, and observe the logarithmic profiles of the bacterial densities near the front. these lead us to define a consolidation front dist ... | 2001 | 11308679 |
