laboratory detection of extended-spectrum-beta-lactamase-producing enterobacteriaceae: evaluation of two screening agar plates and two confirmation techniques.the worldwide prevalence of extended-spectrum-beta-lactamase-producing esbl-producing enterobacteriaceae (esbl-e) is increasing, making the need for optimized detection techniques more urgent. in this study we investigated the performance of two esbl-e screening and two esbl-e confirmation techniques. in accordance with the dutch national guidelines (www.wip.nl), a collection of 642 highly resistant enterobacteriaceae strains, as identified by vitek2, was used to test the performances of two scr ...201021123527
necrotising otitis externa: an unusual cause of cranial nerve palsy in a diabetic haemodialysis patient.we present an unusual case of necrotising otitis externa (noe) causing a lower motor neurone facial nerve palsy in a patient with diabetes mellitus and receiving maintenance haemodialysis for end-stage renal disease (esrd). pseudomonas aeruginosa is the most common pathogen isolated in noe, although our case involved the non-typical pathogens aspergillus flavus and proteus mirabilis. we discuss the need for diagnostic rigour and the importance of considering atypical infective pathology in patie ...201021125035
a child with mental retardation and asymmetrical hypertrophy of limbs.a 5-year-old male child presented with progressively increasing asymmetrical overgrowth of limbs, hyperpigmentation on the right half of the body, and mental retardation since 9 months of age.201021132570
photodynamic therapy with a cationic functionalized fullerene rescues mice from fatal wound infections.fullerenes are under intensive study for potential biomedical applications. we have previously reported that a c60 fullerene functionalized with three dimethylpyrrolidinium groups (bf6) is a highly active broad-spectrum antimicrobial photosensitizer in vitro when combined with white-light illumination. we asked whether this high degree of in vitro activity would translate into an in vivo therapeutic effect in two potentially lethal mouse models of infected wounds.201021143031
structure of the o-polysaccharide from the lipopolysaccharide of providencia alcalifaciens o60.an o-polysaccharide (o-antigen) was isolated by mild acid degradation of the lipopolysaccharide of providencia alcalifaciens o60 and studied by sugar and methylation analyses as well as (1)h and (13)c nmr spectroscopy, including 2d roesy and (1)h,(13)c hmbc experiments in d(2)o and a roesy experiment in a 9:1 h(2)o-d(2)o mixture to reveal correlations for nh protons. it was found that the polysaccharide is built up of linear pentasaccharide repeating units containing an amide of d-glucuronic aci ...201021146157
[comparison of four phenotypic methods to detect extended-spectrum betalactamases].to compare the efficacy of four phenotypic methods for the identification of strains producing extended-spectrum β-lactamases isolated from urine cultures.201021152726

unexpected coregulator range for the global regulator lrp of escherichia coli and proteus mirabilis.the lrp/asnc family of transcription factors links gene regulation to metabolism in bacteria and archaea. members of this family, collectively, respond to a wide range of amino acids as coregulators. in escherichia coli, lrp regulates over 200 genes directly and is well known to respond to leucine and, to a somewhat lesser extent, alanine. we focused on lrp from proteus mirabilis and e. coli, orthologs with 98% identity overall and identical helix-turn-helix motifs, for which a previous study ne ...201021169483
the nationwide study of bacterial pathogens associated with urinary tract infections conducted by the japanese society of chemotherapy.this study was conducted by the japanese society of chemotherapy and is the first nationwide study on bacterial pathogens isolated from patients with urinary tract infections at 28 hospitals throughout japan between january 2008 and june 2008. a total of 688 bacterial strains were isolated from adult patients with urinary tract infections. the strains investigated in this study are as follows: enterococcus faecalis (n = 140), escherichia coli (n = 255), klebsiella pneumoniae (n = 93), proteus mi ...201021174142
synthesis and antimicrobial activity of highly functionalised novel β-lactam grafted spiropyrrolidines and pyrrolizidines.a facile and one-pot synthesis of a series of novel spiropyrrolidines/pyrrolizidines with β-lactam substituent has been accomplished through 1,3-dipolar cycloaddition reaction of alkenyl esters derived from β-lactam aldehyde as dipolarophile with the dipole azomethine ylide derived from 1,2- and 1,3-diketones and secondary amino acids. the synthesized compounds were evaluated for antimicrobial activities and found to exhibit relatively good antibacterial activity at lower concentration against f ...201021177001
asymptomatic bacteriuria among hiv positive pregnant women.the prognostic significance of asymptomatic bacteriuria resides in the observation that the prevalence is, relatively, high in persons with certain medical conditions, such as diabetes mellitus and pregnancy. this prevalence might, even, be higher in patients with human immunodeficiency virus infection. hence, this study set out to determine the prevalence of asymptomatic bacteriuria among symptom free and newly enrolled hiv infected pregnant women attending pmtct unit of antiretroviral clinic o ...201021178431
effect of neem extract against the bacteria isolated from marine fish.marine ornamental fishes are exceedingly valuable due to their high demand in domestic and international markets. there is a growing global interest to rear the fishes in captivity. but problem due to bacteria and fungi are the major hitch in captive condition. since, the use of antibiotics is banned, an attempt was made to ascertain in vitro assay of the neem leaves extract against the bacterial pathogens isolated from infected fishes. bacterial strains isolated from infected regions of the clo ...201021186711
the salmonella genomic island 1 is specifically mobilized in trans by the inca/c multidrug resistance plasmid family.the salmonella genomic island 1 (sgi1) is a salmonella enterica-derived integrative mobilizable element (ime) containing various complex multiple resistance integrons identified in several s. enterica serovars and in proteus mirabilis. previous studies have shown that sgi1 transfers horizontally by in trans mobilization in the presence of the inca/c conjugative helper plasmid pr55.201021187963
