post-operative wound infection in salvage laryngectomy: does antibiotic prophylaxis have an impact?salvage laryngectomy carries a high risk of post-operative infection with reported rates of 40-61%. the purpose of this study was to analyse infections in our own patients and review the potential impact of our current antibiotic prophylaxis (ap). a retrospective analysis of infection in 26 consecutive patients between 2000 and 2010 undergoing salvage total laryngectomy (sl) following recurrent laryngeal cancer after failed radiotherapy or chemo-radiation was undertaken. the antibiotic prophylax ...201222274693
molecular analysis of the genus anoxybacillus based on sequence similarity of the genes recn, flaa, and ftsy.genome predictions based on selected genes would be a very welcome approach for taxonomic studies. we analyzed three genes, recn, flaa, and ftsy, for determining if these genes are useful tools for systematic analyses in the genus anoxybacillus. the genes encoding a dna repair and genetic recombination protein (recn), the flagellin protein (flaa), and gtpase signal docking protein (ftsy) were sequenced for ten anoxybacillus species. the sequence comparisons revealed that recn sequence similariti ...201222223049
coastal seawater bacteria harbor a large reservoir of plasmid-mediated quinolone resistance determinants in jiaozhou bay, china.diversity and prevalence of plasmid-mediated quinolone resistance determinants were investigated in environmental bacteria isolated from surface seawater of jiaozhou bay, china. five qnr gene alleles were identified in 34 isolates by pcr amplification, including qnra3 gene in a shewanella algae isolate, qnrb9 gene in a citrobacter freundii isolate, qnrd gene in 22 proteus vulgaris isolates, qnrs1 gene in 1 enterobacter sp. and 4 klebsiella spp. isolates, and qnrs2 gene in 1 pseudomonas sp. and 4 ...201222252223
a case of proteus syndrome with severe spinal canal stenosis, scoliosis, and thoracic deformity associated with tethered cord.proteus syndrome is a rare, sporadic, hamartomatous disorder manifesting with multifocal overgrowth of tissue. the features seem to develop most often during childhood. vertebral overgrowth with severe spinal canal stenosis is unusual, although scoliosis with abnormal vertebral bodies is one of the typical features of proteus syndrome. we report a case of proteus syndrome with severe spinal canal stenosis, scoliosis, cervical kyphosis, and thoracic deformity with airway obstruction because of as ...201222223075

proteus mirabilis interkingdom swarming signals attract blow flies.flies transport specific bacteria with their larvae that provide a wider range of nutrients for those bacteria. our hypothesis was that this symbiotic interaction may depend on interkingdom signaling. we obtained proteus mirabilis from the salivary glands of the blow fly lucilia sericata; this strain swarmed significantly and produced a strong odor that attracts blow flies. to identify the putative interkingdom signals for the bacterium and flies, we reasoned that as swarming is used by this bac ...201222237540
antimicrobial susceptibility of gram-negative pathogens isolated from patients with complicated intra-abdominal infections in south african hospitals (smart study 2004-2009): impact of the new carbapenem breakpoints.abstract background: the study for monitoring antimicrobial resistance trends (smart) follows trends in resistance among aerobic and facultative anaerobic gram-negative bacilli (gnb) isolated from complicated intra-abdominal infections (ciais) in patients around the world. methods: during 2004-2009, three centralized clinical microbiology laboratories serving 59 private hospitals in three large south african cities collected 1,218 gnb from complicated intra-abdominal infections (ciais) and t ...201222220506
french results of the aresc study: clinical aspects and epidemiology of antimicrobial resistance in female patients with cystitis. implications for empiric therapy.objective: uncomplicated cystitis is one of the most frequent community infections. we report the french results of the international aresc study on the clinical aspects, epidemiology, and antimicrobial susceptibility of uropathogens. patient and methods: female patients between 18 and 65 years of age, with symptoms of uncomplicated cystitis, were investigated clinically with urinalysis and urine culture. uropathogens were identified and their susceptibility was tested with nine antimicrobials. ...201222264668
effect of curcumin against proteus mirabilis during crystallization of struvite from artificial urine.we investigated the activity of curcumin against proteus mirabilis and the struvite crystallization in relation to urinary stones formation. in order to evaluate an activity of curcumin we performed an in vitro experiment of struvite growth from artificial urine. the crystallization process was induced by proteus mirabilis to mimic the real urinary tract infection, which usually leads to urinary stone formation. the results demonstrate that curcumin exhibits the effect against proteus mirabilis ...201221808656
development of an "early warning" sensor for encrustation of urinary catheters following proteus infection.biofilm formation in long-term urinary catheterized patients can lead to encrustation and blockage of urinary catheters with serious clinical complication. catheter encrustation stems from infection with urease-producing bacteria, particularly proteus mirabilis. urease generates ammonia from urea, and the elevated ph of the urine results in crystallization of calcium and magnesium phosphates, which block the flow of urine. the aim of this research is to develop an "early warning" silicone sensor ...201221954120
Bacterial infections of Chinook salmon, Oncorhynchus tshawytscha (Walbaum), returning to gamete collecting weirs in Michigan.Herein, we describe the prevalence of bacterial infections in Chinook salmon, Oncorhynchus tshawytscha (Walbaum), returning to spawn in two tributaries within the Lake Michigan watershed. Ten bacterial genera, including Renibacterium, Aeromonas, Carnobacterium, Serratia, Proteus, Pseudomonas, Hafnia, Salmonella, Shewanella and Morganella, were detected in the kidneys of Chinook salmon (n = 480) using culture, serological and molecular analyses. Among these, Aeromonas salmonicida was detected at ...201222168454
Perturbation of FliL Interferes with Proteus mirabilis Swarmer Cell Gene Expression and Differentiation.Proteus mirabilis is a dimorphic, motile bacterium often associated with urinary tract infections. Colonization of urinary tract surfaces is aided by swarmer cell differentiation, which is initiated by inhibition of flagellar rotation when the bacteria first contact a surface. Mutations in fliL, encoding a flagellar structural protein with an enigmatic function, result in the inappropriate production of differentiated swarmer cells, called pseudoswarmer cells, under noninducing conditions, indic ...201222081397
Diversity and assessment of potential risk factors of Gram-negative isolates associated with French cheeses.The goal of this study was to identify at the species level a large collection of Gram-negative dairy bacteria isolated from milks or semi-hard and soft, smear-ripened cheeses (cheese core or surface samples) from different regions of France. The isolates were then assessed for two risk factors, antibiotic resistance and volatile and non-volatile biogenic amine production in vitro. In total, 173 Gram-negative isolates were identified by rrs and/or rpoB gene sequencing. A large biodiversity was o ...201222029922
isolated macrodystrophia lipomatosa of the foot in a neonate: a case report.macrodystrophia lipomatosa characterized by enlargement of one or more fingers or toes with predominantly fibroadipose tissue can be part of an overgrowth syndrome such as proteus syndrome (biesecker, 2006) or cloves syndrome(sapp et al., 2007; alomari, 2009) or found as an isolated abnormality in an otherwise normal patient. it maybe present at birth or occur in early infancy with a progressive course. here, we report a case of macrodystrophia lipomatosa (mdl) diagnosed in the neonatal period i ...201221959860
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 ...201221956834
