laboratory detection of extended-spectrum beta-lactamase by an automated system.this study aims to evaluate the positive predictive value (ppv) and the negative predictive value (npv) of vitek2 in detecting extended-spectrum beta-lactamase (esbl) phenotypes when compared to a manual confirmatory test as gold standard. a sample of escherichia coli, klebsiella spp and proteus mirabilis isolates were collected by 5 laboratories in the emilia-romagna region (italy). vitek2 appears to be an accurate tool to detect esbl phenotypes of e. coli isolates; some concern remains about i ...200819123314
large scale multiplex pcr improves pathogen detection by dna microarrays.medium density dna microchips that carry a collection of probes for a broad spectrum of pathogens, have the potential to be powerful tools for simultaneous species identification, detection of virulence factors and antimicrobial resistance determinants. however, their widespread use in microbiological diagnostics is limited by the problem of low pathogen numbers in clinical specimens revealing relatively low amounts of pathogen dna.200919121223

[recent evolution and characterization of extended-spectrum beta-lactamase producing enterobacteria in the chu of nice (2005-2007)].esbl producing enterobacteria (e-esbl+) are always a public health concern, mainly due to increase of ctx-m beta-lactamase. so, 542 new strains were isolated in the chu de nice during the 2005-2007 period. the aim of this work was to characterize the esbl and to type isolates suspected to be implicated in outbreaks.200818848404
experimental and qsar of acetophenones as antibacterial agents.antibacterial activity of 20 acetophenone derivatives was evaluated against two gram-positive and three gram-negative organisms, namely, bacillus subtilis ncim 2718, staphylococcus aureus ncim5021, salmonella typhi ncim2501, enterobacter aerogenes ncim5139, and proteus vulgaris ncim2813 by two-fold dilution method. the most active amongst this group of compounds were 4-methyl, 2-hydroxy, 3-bromo, 4-ethoxy, 3-nitro and 4-nitro acetophenones. quantitative structure-activity relationships were deve ...200818844677
[fluoroquinolones and gram-negative bacteria: antimicrobial activity and mechanisms of resistance].fluoroquinolones acts by interacting with type ii topoisomerases (dna gyrase and topoisomerases iv). related to this mechanism of action, bacteria have developed resistance mechanisms consisting in some target mutations (gyra/gyrb for dna gyrase and parc/pare for topoisomerase iv) or in a reduced access to the target itself, by either decreased permeability or augmented expression of efflux pumps, such as acrab and mexab. along with these classical mechanisms of chromosomal resistance, the prese ...200818843219
uropathogens and host characteristics.uropathogens other than escherichia coli occur with greater frequency in patients with risk factors for urinary tract infection (uti). however, little is known about associations between uropathogen species and host characteristics. three hundred nineteen urine specimens containing a balanced distribution of uropathogen species were selected from inpatients and outpatients at a university hospital clinical microbiology laboratory. information on host characteristics was retrospectively collected ...200818842936
[macrodactylies of the hand and foot].macrodactyly is a rare congenital anomaly defined by an enlargement of all the structures of fingers or toes. two forms of macrodactyly have been described. one form is static with an enlargement present at birth and growing proportionately to the other digits. the other is progressive with an enlargement beginning in early childhood and growing faster than that of the normal digits. macrodactyly is responsible of a functional handicap and an aesthetic prejudice. treatment may be indicated for t ...200818842439
[the analysis of the bacterial and fungal flora in maxillary sinuses in patients operated due to fess method].the aim of this work was to analyse the bacterial and fungal flora in maxillary sinuses in patients operated due to the fess method.200818837224
distribution frequency of pathogenic bacteria isolated from cutaneus leishmaniasis lesions.cutaneous leishmaniasis (cl) is a parasitic disease characterized by single or multiple ulcerations. secondary bacterial infections are one of the complications that can increase the tissue destruction and the resulting scar. to better determine the incidence of real secondary bacterial infections in cl, we designed the current study. this was a cross-sectional study performed in skin diseases and leishmaniasis research centre, isfahan, iran. a total of 1,255 patients with confirmed cl enrolled ...200818830062
causative agents of urinary tract infections in children and their antibiotic sensitivity pattern: a hospital based study.a retrospective study was conducted to find out the causative agents of urinary tract infection (uti) in children and their antibiotic sensitivity pattern among nepalese children. this was done at kanti children's hospital in kathmandu (nepal) by analyzing the records of urine samples collected for culture and sensitivity tests over a period of six months (april to november, 2007). of the total 1878 mid-stream urine samples collected from suspected cases of uti, 538 (28.6%) were positive for pat ...200818828428
synthesis and biological activities of new hydrazide derivatives.the synthesis of a new series of imidazo[1,2-a]pyrazine-2-carboxylic acid arylidene-hydrazides is described. the chemical structures of the compounds were elucidated by ir, (1)h-nmr, fab(+)-ms spectral data. their biological activity against various bacteria, fungi species, and mycobacterium tuberculosis was investigated. antibacterial activity was measured against escherichia coli (nrrl b-3704), staphylococcus aureus (nrrl b-767), salmonella typhimurium (nrrl b-4420), proteus vulgaris (nrll b-1 ...200918825530
inhibition of candida albicans isocitrate lyase activity by sesterterpene sulfates from the tropical sponge dysidea sesterterpene sulfates (1-7) were isolated from the tropical sponge dysidea sp. and their inhibitory activities against isocitrate lyase (icl) from candida albicans were evaluated. among the isolated natural products compound 6 and 7 were found to be strong icl inhibitors. the isolated compounds (1-7) also showed potent antibacterial effect against bacillus subtilis and proteus vulgaris, but did not display antifungal activity.200818824352
