notes on the microbiology of cholesteatoma: clinical findings and treatment.anomalous proliferation of the cholesteatoma epithelium is caused by extrinsic factors such as toxins or bacterial antigens combined with lytic enzymes, lymphokines and cytokines released from the inflammatory infiltrate. this could explain the close relationship between the aggressiveness of cholesteatoma and repeated bacterial superinfection, therefore it is very important to know the bacteria involved in order to control the regrowth of skin following surgery, reduce the aggressive potential ...200920161877
characterization of udp-glucose dehydrogenase and udp-glucose pyrophosphorylase mutants of proteus mirabilis: defectiveness in polymyxin b resistance, swarming, and virulence.proteus mirabilis is known to be highly resistant to the action of polymyxin b (pb). however, the mechanism underlying pb resistance is not clear. in this study, we used tn5 transposon mutagenesis to identify genes that may affect pb resistance in p. mirabilis. two genes, ugd and galu, which may encode udp-glucose dehydrogenase (ugd) and udp-glucose pyrophosphorylase (galu), respectively, were identified. knockout mutants of ugd and galu were found to be extremely sensitive to pb, presumably bec ...201020160049
assessment upon azo dye decolorization and bioelectricity generation by proteus hauseri.this study explored dye decolorization and bioelectricity generation of indigenous proteus hauseri zmd44 for dye-bearing wastewater treatment. chemical structures of azo dyes apparently affected the performance of dye biodecolorization. additions of diazo dye c.i. reactive blue 160 (rbu160) stimulated simultaneous dye decolorization and bioelectricity generation of zmd44 in single chamber microbial fuel cells (mfcs). however, high-level additions of rbu160 repressed capabilities of power product ...201020156682
differential characterization of biogenic amine-producing bacteria involved in food poisoning using maldi-tof mass fingerprinting.histamine poisoning is caused by the consumption of fish and other foods that harbor bacteria possessing histidine decarboxylase activity. with the aim of preventing histamine formation, highly specific mass spectral fingerprints were obtained from the 16 major biogenic amine-producing enteric and marine bacteria by means of maldi-tof ms analysis. all bacterial strains analyzed exhibited specific spectral fingerprints that enabled its unambiguous differentiation. this technique also identified p ...201020151397

use of the cefepime-clavulanate esbl etest for detection of extended-spectrum beta-lactamases in ampc co-producing bacteria.extended-spectrum beta-lactamases (esbls) may not always be detected in routine susceptibility tests. this study reports the performance of the cefepime-clavulanate esbl etest for the detection of esbls in enterobacteriaceae, including those producing ampc enzyme.200920130375
proteus mirabilis pmri, an rppa-regulated gene necessary for polymyxin b resistance, biofilm formation, and urothelial cell invasion.proteus mirabilis is naturally resistant to polymyxin b (pb). to investigate the underlying mechanisms, tn5 mutagenesis was performed, and a mutant exhibiting increased pb susceptibility was isolated. the mutant was found to have tn5 inserted into the ppmri (proteus pmri) gene, a gene which may encode a udp-glucuronic acid decarboxylase. in other bacteria, pmri belongs to the seven-gene pmrf operon, which is involved in lipopolysaccharide (lps) modification. while the ppmri knockout mutant had a ...201020123999
extended-spectrum beta-lactamase-producing escherichia coli in patients with travellers' diarrhoea.the identification of patients carrying extended-spectrum beta-lactamase (esbl)-producing bacteria is important, since these patients are at risk of receiving inappropriate empirical therapy if they become infected. the purpose of this study was to investigate the occurrence of esbl-producing bacteria in patients with travellers' diarrhoea. patients with travellers' diarrhoea (n = 242) having delivered stool samples for the diagnosis of salmonella, shigella, yersinia or campylobacter, were also ...201020121649
parental preference or child well-being: an ethical dilemma.an ethical dilemma that is not uncommon to encounter when caring for children occurs when parental preference does not appear to be in the child's best interest. challenges facing the health care team are further amplified when the family's cultural background does not match that of the team. a case study will be used to illustrate the challenges of a pediatric palliative care ethical dilemma further complicated by cultural diversity. review of the child's medical condition, patient/parent prefe ...201020117678
