plasmid-mediated quinolone resistance in expanded spectrum beta lactamase producing enterobacteriaceae in morocco.although independently acquired, plasmid-mediated quinolone resistance appears to be linked with extended-spectrum or ampc-type beta-lactamases. since no data are available in african countries, the prevalence of qnr genes at the university hospital ibn rochd, casablanca, morocco, was investigated.201021252459
assessment of effectiveness and safety of ibicella lutea extract in the control of experimental proteus mirabilis urinary tract infection.proteus mirabilis is an important cause of complicated urinary tract infections (uti). like many other microorganisms, p. mirabilis has acquired resistance to many antibiotics. due to the serious effects associated with uropathogenic p. mirabilis and the problems related to the use of antibiotics, alternative strategies for its control must be developed. previously, we studied the effect of ibicella lutea extract, a south american indigenous plant, on in vitro uropathogenicity of p. mirabilis. w ...201021252462
microbial evaluation and public health implications of urine as alternative therapy in clinical pediatric cases: health implication of urine therapy.cultural means of pediatric treatment during ill health is a mainstay in africa, and though urine has been known to contain enteric pathogens, urine therapy is still culturally applicable in some health conditions and also advocated as alternative therapy. the study therefore, is to evaluate the microbial contents and safety of urine.201021293739

Preventing catheter-related urinary tract infection: focus on Proteus mirabilis.Urinary tract infectious caused by Proteus are uncommon, and account for only 1-2% of community-acquired infectious. However, it is important that staff are able to recognise the features of a Proteus infection. Proteus infections, if unrecognised, can become established and cause major health problems. Proteus is more common in people who have or have had a urinary catheter. Minimizing the incidence and duration of urinary catheterization is an important part of preventing infection. Community ...201122145192
Macrodystrophia lipomatosa involving multiple nerves.Macrodystrophia lipomatosa (MDL), a rare congenital disorder, is considered by some to be a localized form of Proteus syndrome. The implication of the PTEN (phosphatase and tensin homolog deleted on chromosome 10) gene in both strengthens this belief. We present a case who had MDL in multiple nerve territories-all on the same side of the body-with hypertrophy of mainly fibroadipose tissue throughout their distribution, thus pointing to a form of localized hemihypertrophy; both hemihypertrophy an ...201121948052
[effect of acetylcholine and acetylcholinesterase on the activity of contractile vacuole of amoeba proteus].acetylcholine (ach, 1 microm) stimulates activity of the contractile vacuole of proteus. the effect of ach is not mimicked by its analogs which are not hydrolyzed by acetylcholinesterase (ache), i. e., carbacholine and 5-methylfurmethide. the effect of ach is not sensitive to the blocking action of m-cholinolytics, atropine and mytolone, but is suppressed by n-cholinolytic, tubocurarine. the inhibitors of ache, eserine (0.01 microm) and armine (0.1 microm), suppress the effect of ach on amoeba c ...201121870511

proteus mirabilis biofilms and catheter-associated urinary tract infections.proteus mirabilis inhabits the environment and causes a number of infections including those of the skin, respiratory tract, wounds and urinary tract. these organisms express virulence factors associated with adhesion, motility, immunoavoidance, nutrient acquisition, host damage, as well as biofilm formation. p. mirabilis produces biofilms in diverse habitats with those formed in the human host playing a key role in indwelling device infections. the most studied p. mirabilis biofilms are those f ...201121921687
radial and spiral stream formation in proteus mirabilis colonies.the enteric bacterium proteus mirabilis, which is a pathogen that forms biofilms in vivo, can swarm over hard surfaces and form a variety of spatial patterns in colonies. colony formation involves two distinct cell types: swarmer cells that dominate near the surface and the leading edge, and swimmer cells that prefer a less viscous medium, but the mechanisms underlying pattern formation are not understood. new experimental investigations reported here show that swimmer cells in the center of the ...201122219724

application of high-throughput sequencing to measure the performance of commonly used selective cultivation methods for the foodborne pathogen campylobacter.campylobacter is an important foodborne human pathogen, which has traditionally been studied using a variety of selective cultivation methods. here we use next-generation sequencing to ask the following: (i) how selective are commonly used campylobacter cultivation methods relative to the initial sample and (ii) how do the specificity and sensitivity of these methods compare with one another? to answer these questions, we used 16s rrna tagged-pyrosequencing to sequence directly from a pooled fec ...201122092388
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 ...201122198843
prevalence of viral, bacterial and parasitological diseases in rats and mice used in research environments in australasia over a 5-y period.viral, bacterial and parasitological infections in rats and mice used in biomedical research continue to occur despite improved housing and biosurveillance. the presence of disease in laboratory animals can lead to spurious results for research undertaken in universities, research institutes and the pharmaceutical industry. here the authors report the results of serological, microbiological, parasitological and molecular tests done on mice and rats from australasia submitted to a rodent health m ...201122012194

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 ...201122201529
Impact of adopting minimum inhibitory concentration as the determinant of susceptibility to cephalosporins and carbapenems in multi-drug resistant Enterobacteriaceae.The Clinical and Laboratory Standards Institute has recommended that Enterobacteriaceae susceptibility to most cephalosporins and carbapenems be reported according to minimum inhibitory concentration (MIC) alone. We analyzed our record of multi-drug resistant Enterobacteriaceae to assess the impact of these changes. We compared susceptibilities of ceftriaxone-resistant Enterobacteriaceae when using the 2009 and new 2010 MIC standards. Vitek2® (BioMerieux), was used to assess the changes in susce ...201121912922

Deciphering simultaneous bioelectricity generation and dye decolorization using Proteus hauseri.This first-attempt study disclosed how and why electron-shuttling mediators were capable to stimulate bioelectricity-generating capabilities of dye-bearing microbial fuel cells (MFCs) using Proteus hauseri. Due to significant biotoxicity of 4-aminophenol (4AP) and the absence of electron-mediating potential of 3AP, only 2AP among all isomers could work as an exogenous mediator to stimulate bioelectricity generation of P. hauseri. Dye toxicity to cells on anodic biofilm in MFCs apparently affecte ...201122178022
