| new tem variant (tem-92) produced by proteus mirabilis and providencia stuartii isolates. | the sequences of the bla(tem) genes encoding tem-92 in proteus mirabilis and providencia stuartii isolates were determined and were found to be identical. except for positions 218 (lys-6) and 512 (lys-104), the nucleotide sequence of bla(tem-92) was identical to that of bla(tem-20), including the sequence of the promoter region harboring a 135-bp deletion combined with a g-162-->t substitution. the deduced amino acid sequence of tem-92 differed from that of tem-52 by the presence of a substituti ... | 2001 | 11257046 |
| epigenetic regulation of carnitine metabolising enzymes in proteus sp. under aerobic conditions. | proteus sp. is able to catalyse the reversible transformation of crotonobetaine into l(-)-carnitine during aerobic growth. contrary to other enterobacteriaceae no reduction of crotonobetaine into gamma-butyrobetaine could be detected in the culture supernatants. activities of l(-)-carnitine dehydratase, carnitine racemasing system and crotonobetaine reductase could be determined enzymatically in cell-free extracts of proteus sp. small amounts of gamma-butyrobetaine were found in cell-free extrac ... | 2001 | 11257539 |
| interaction of bladder glycoprotein gp51 with uropathogenic bacteria. | a major component of bladder surface mucin is a glycoprotein gp51 (molecular weight 51 kd.). gp51, which has previously been isolated from rabbit mucosa, appears to function as part of the defense mechanism in an in vivo infection model. gp51 coats the epithelium and is secreted into the urine, as detected by immunohistochemical testing and enzyme-linked immunosorbent assay (elisa). increased urinary gp51 occurs during urinary tract infection. to elucidate the role of gp51 as a component of the ... | 2001 | 11257713 |
| comparison of the pr mutant with the wild-type strain of proteus mirabilis brings insight into peroxide resistance factors and regulation of catalase expression. | the peroxide resistant mutant (pr) of proteus mirabilis was characterized by an increased constitutive catalase activity concomitant with a large production of specific mrna. survival toward hydrogen peroxide during exponential phase was increased by h2o2 pretreatment in the wild type but not in the mutant, although the catalase of both strains was not inducible under these conditions. in the mutant, besides catalase, over-produced proteins comprised two different alkyl hydroperoxide reductase s ... | 2001 | 11261492 |
| differentiation of bacterial autolysins by zymogram analysis. | the use of zymograms in which the bacterial cell wall heteropolymer peptidoglycan is incorporated into the resolving gel of sds-page has led to the identification of various sds stable peptidoglycan hydrolases (autolysins). to examine the specificity of autolysins with respect to o-acetylated peptidoglycan, a discontinuous sds-page system has been developed that operates under neutral conditions. [bis(2-hydroxyethyl)imino]tris(hydroxymethyl)methane (bis-tris) buffers are employed with ph 6.8 and ... | 2001 | 11262168 |

| 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 |
| 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 |

| postantibiotic suppression effect of macrolides on the expression of flagellin in pseudomonas aeruginosa and proteus mirabilis. | the phenomenon of postantibiotic effect (pae) encompasses not only the effects of bacterial growth inhibition but also the suppression of virulence factors. we tentatively designated the latter effect the postantibiotic suppression effect (pase). the flagella of gram-negative bacteria are involved in the development of biofilms. we measured the pase of erythromycin (ery) and azithromycin (azm) on the expression of flagellin in pseudomonas aeruginosa and proteus mirabilis. flagellin preparations ... | 2001 | 11406758 |
| 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 |
| 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 |
| 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 |
| 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 |
