| emerging from obscurity: biological, clinical, and diagnostic aspects of dientamoeba fragilis. | ever since its first description in 1918, dientamoeba fragilis has struggled to gain recognition as a significant pathogen. there is little justification for this neglect, however, since there exists a growing body of case reports from numerous countries around the world that have linked this protozoal parasite to clinical manifestations such as diarrhea, abdominal pain, flatulence, and anorexia. a number of studies have even incriminated d. fragilis as a cause of irritable bowel syndrome, aller ... | 2004 | 15258093 |
| frequency and diversity of class a extended-spectrum beta-lactamases in hospitals of the auvergne, france: a 2 year prospective study. | to evaluate the frequency and diversity of extended-spectrum beta-lactamases (esbls) produced by enterobacteriaceae and pseudomonas aeruginosa in one french region. | 2004 | 15282240 |
| cloning and expression of the vitreoscilla hemoglobin gene in enterobacter aerogenes: effect on cell growth and oxygen uptake. | the hemoglobins found in unicellular organisms show a greater chemical reactivity, protect cells against oxidative stress and hence have been implicated in a wider variety of potential functions than those traditionally associated with animal and plant hemoglobins. there are well-documented studies showing that bacteria expressing vitreoscilla hemoglobin (vhb), the first prokaryotic hemoglobin characterized, have better growth and oxygen uptake rates than vhb counterparts. | 2004 | 15283330 |
| spermidine/spermine-n1-acetyltransferase-2 (ssat2) acetylates thialysine and is not involved in polyamine metabolism. | spermidine/spermine-n1-acetyltransferase (ssat1) is a short-lived polyamine catabolic enzyme inducible by polyamines and polyamine analogues. induction of ssat1 plays an important role in polyamine homoeostasis, since the n1-acetylated polyamines can be excreted or oxidized by acetylpolyamine oxidase. we have purified a recombinant human acetyltransferase (ssat2) that shares 45% identity and 61% homology with human ssat1, but is only distally related to other known members of the gnat (gcn5-rela ... | 2004 | 15283699 |
| recommended test panel for differentiation of klebsiella species on the basis of a trilateral interlaboratory evaluation of 18 biochemical tests. | klebsiella pneumoniae and klebsiella oxytoca are the two most frequently encountered klebsiella species giving rise to infections in humans, but other klebsiella species can also be found in clinical specimens: klebsiella ozaenae, klebsiella rhinoscleromatis, klebsiella terrigena, klebsiella planticola, klebsiella ornithinolytica, and enterobacter aerogenes (klebsiella mobilis). however, many of these species are indistinguishable by the conventional methods employed routinely in the clinical mi ... | 2004 | 15297514 |
| molecular epidemiology of enterobacteriaceae isolates producing extended-spectrum beta-lactamases in a french hospital. | in 2002, 80 isolates of enterobacteriaceae producing extended-spectrum beta-lactamases (esbls) were collected from infected patients in our hospital. enterobacter aerogenes was the most common bacterium isolated from all specimens (36.5%). the esbls were predominantly (90%) tem derivatives (tem-24, tem-3). pulsed-field gel electrophoresis highlighted that e. aerogenes, klebsiella pneumoniae, and citrobacter koseri had a clonal propagation. | 2004 | 15297534 |
| enhanced production of acetoin and butanediol in recombinant enterobacter aerogenes carrying vitreoscilla hemoglobin gene. | microbial production of butanediol and acetoin has received increasing interest because of their diverse potential practical uses. although both products are fermentative in nature, their optimal production requires a low level of oxygen. in this study, the use of a recombinant oxygen uptake system on production of these metabolites was investigated. enterobacter aerogenes was transformed with a puc8-based plasmid carrying the gene (vgb) encoding vitreoscilla (bacterial)hemoglobin (vhb). the pre ... | 2004 | 15309606 |
| the acrab-tolc pump is involved in macrolide resistance but not in telithromycin efflux in enterobacter aerogenes and escherichia coli. | the role of the acrab-tolc pump in macrolide and ketolide susceptibility in escherichia coli and enterobacter aerogenes was studied. efflux pump inhibitor restored erythromycin, clarithromycin, and telithromycin susceptibilities to multidrug-resistant isolates. no modification of telithromycin accumulation was detected in e. aerogenes acrab or tolc derivatives compared to that in the parental strain. two independent efflux pumps, inhibited by phenylalanine arginine beta-naphthylamide, expel macr ... | 2004 | 15328143 |
| co-infection of the macronucleus of paramecium caudatum by free-living bacteria together with the infectious holospora obtusa. | infection experiments were performed incubating paramecium caudatum with non-infectious free-living bacteria or weakly infectious intracellular bacteria together with the infectious holospora obtusa. two of four non-infectious free-living bacteria (enterobacter aerogenes and klebsiella pneumoniae) were found to get into the nuclei when added to paramecium together with h. obtusa. the endonuclear bacterium nonospora macronucleata that is weakly infectious by itself increases its infectivity when ... | 2004 | 15352323 |
| dissemination of transferable ampc-type beta-lactamase (cmy-10) in a korean hospital. | to determine dissemination and genotype of ampc beta-lactamases and an extended-spectrum beta-lactamase among clinical isolates of enterobacteriaceae, we performed antibiotic susceptibility testing, pi determination, induction test, plasmid profiles, transconjugation test, enterobacterial repetitive consensus (eric)-pcr, and dna sequencing. among the 51 clinical isolates collected from a university hospital in korea, six isolates were resistant to cephamycins. all six isolates produced a plasmid ... | 2004 | 15383166 |
