[characteristics of war wound infection].war wounds are the most complex type of non-targeted injuries due to uncontrolled tissue damage of varied and multifold localizations, exposing sterile body areas to contamination with a huge amount of bacteria. wound contamination is caused by both the host microflora and exogenous agents from the environment (bullets, cloth fragments, dust, dirt, water) due to destruction of the host protective barriers. war wounds are the consequence of destructive effects of various types of projectiles, whi ...200617048790
[development of beta-lactamase resistance in enterobacteria].enterobacteria produce elementary chromosomal enzymes, beta-lactamases of class a: tem and shv (escherichia coli, klebsiella pneumoniae). these can give rise to plasmid-coded broad-spectrum beta-lactamases (esbl) discovered in 1980 (e. coli, k. pneumoniae, enterobacter cloacae). the first cefotaximase (ctx-m, men-1) was reported in europe in 1990. this enzyme is far more active against cefotaxime than against ceftazidime and aztreonam. chromosomal hyperpoduction of k1 beta-lactamase differs from ...200617051471

the first detection of ctx-m-14 extended-spectrum beta-lactamase among diverse beta-lactamase-producing proteus mirabilis clinical isolates.ctx-m-14- and -2-like extended-spectrum beta-lactamases were detected in 5 and 1 proteus mirabilis isolates, respectively, among 92 non-duplicate strains tested from december 2002 to september 2003. this is the first report of the ctx-m-14 enzyme in p. mirabilis to the best of our knowledge and suggests that the ctx-m-type enzyme is gradually spreading to this species. bla(tem), bla(shv-1), and/or bla(oxa-10) alleles were also detected in 35 ampicillin-resistant isolates tested.200616427241
emergence of proteus mirabilis carrying the bla metallo-beta-lactamase genetically related proteus mirabilis clinical isolates from a hospital in thessaloniki, greece, exhibited decreased susceptibility to imipenem and carried a bla(vim-1) metallo-beta-lactamase gene. pcr mapping revealed that bla(vim-1) was part of a class 1 integron that was probably located in the chromosome and also included the aaca7, dhfr and aada genes. this is the first description of the bla(vim-1) metallo-beta-lactamase gene in p. mirabilis.200616774572
improving the accuracy of protein secondary structure prediction using structural alignment.the accuracy of protein secondary structure prediction has steadily improved over the past 30 years. now many secondary structure prediction methods routinely achieve an accuracy (q3) of about 75%. we believe this accuracy could be further improved by including structure (as opposed to sequence) database comparisons as part of the prediction process. indeed, given the large size of the protein data bank (>35,000 sequences), the probability of a newly identified sequence having a structural homol ...200616774686
biofilm formation in an ice cream plant.the sites of biofilm formation in an ice cream plant were investigated by sampling both the production line and the environment. experiments were carried out twice within a 20-day period. first, stainless steel coupons were fixed to surfaces adjacent to food contact surfaces, the floor drains and the doormat. they were taken for the analysis of biofilm at three different production stages. then, biofilm forming bacteria were enumerated and also presence of listeria monocytogenes was monitored. b ...200616779628

trends in production of extended-spectrum beta-lactamases among enterobacteria of medical interest: report of the second italian nationwide survey.results of a 2003 survey carried out in italy to evaluate the prevalence of extended-spectrum beta-lactamase (esbl)-producing enterobacteria are presented. eleven italian microbiology laboratories investigated 9,076 consecutive nonreplicate isolates (inpatients, 6,850; outpatients, 2,226). esbl screening was performed by mic data analysis. confirmation was obtained using the double-disk synergy test and the combination disk test based on clsi methodology. esbl determinants were investigated by c ...200616672390
functional grouping based on signatures in protein termini.the two ends of each protein are known as the amino (n-) and carboxyl (c-) termini. short signatures in a protein's termini often carry vital cellular function. no systematic research has been conducted to address the importance of short signatures (3 to 10 amino acids) in protein termini at the proteomic level. specifically, it is unknown whether such signatures are evolutionarily conserved, and if so, whether this conservation confers shared biological functions. current signature detection me ...200616475191
performance in detection and reporting beta-lactam resistance phenotypes in enterobacteriaceae: a nationwide proficiency study in italian laboratories.we evaluated the ability of 60 italian clinical microbiology laboratories in detecting and reporting beta-lactam resistance phenotypes in enterobacteriaceae. laboratories received 5 well-characterized isolates producing extended-spectrum beta-lactamases (esbls), 2 hyperproducers of chromosomal enzymes, and 3 quality control strains. the performances in antimicrobial susceptibility testing (ast) were different depending on the species and type of esbl produced. high rates of very major errors (up ...200616678993
