given the inappropriate use of antibiotics and prevalence of resistant bacteria, there is urgentneed for antibacterial drugs that have fewer side effects than antibiotics. satureja bachtiaricais a medicinal plant which had many uses in traditional medicine. in this research, the ethanolextract of leave of satureja bachtiarica is tested on coagulase-negative staphylococcus strains.materials and ...

conclusions vancomycin, but not teicoplanin, can be considered an effective antibiotic of choice for controlling infections caused by mdr cons in gorgan, depending on the bacterial species. background coagulase-negative staphylococci (cons) are clinically important, especially in nosocomial and neonatal infections. the increasing emergence of glycopeptide-resistant cons has made these agents th...

background and objectives: patients at intensive-care-unit (icu) are at risk of acquiring nosocomial infections which contributes to higher rates. approximately 25% of all hospital infections and 90% of outbreaks occur in icus. multi-resistant gram-negative rods are important pathogens in icus, causing high rate of mortality. the purpose of this study was to investigate the antimicrobial resist...

the nosocomial infections, caused by multi-drug resistant bacteria, are the most important cause of mortality throughout the world. one important mechanism against beta-lactam antibiotics is the production of beta-lactamases. enterobacteriaceae and non-fermentative bacteria, like pseudomonas aeruginosa and acinetobacter baumannnii may produce these enzymes. currently, there is no vaccine to pre...

conclusions with regards to the continuous changing in causative microorganisms isolated from patients with uti and antibiotic sensitivity patterns, it is recommended that bacterial sensitivity patterns in populations are determined in any region annually. . objectives this study aimed to detect and also compare the frequency and drug resistance pattern of gram negative bacteria isolated from p...

antibiotic resistance of intensive care unit (icu) born aerobic gram-negative bacteria was evaluated during a six months period at a teaching hospital in tehran, and determination of the validity of the results obtained from disc diffusion tests, using discs manufactured in iran. disc susceptibility tests using iranian and standard discs (diffusion discs available in international markets) were...

patients and methods: all samples sent to the lab were routinely processed according to standard microbiological procedures and the cultures yielding growth of cons were selected for the study. all samples containing cons collected over a 2 year-period, were included irrespective of patients' age and gender. the antibiogram of the organisms was recorded according to clsi guidelines and the rati...

background and objectives: non-fementer gram-negative bacilli (nfgb) are ubiquitous pathogen that has emerged as a major cause of health care associated infections. the aim of this study was to determine the prevalence and antimicrobial susceptibility of   nfgb in an iranian hospital. materials and methods: fromjuly 2005 to november 2006 a total of 257 strains of nfgb including 109 (42.41%) str...

conclusions our results showed the rate of effects of different risk factors on imipenem resistance. regarding the studied risk factors, appropriate programs must be set in place to control and prevent imipenem resistance in gram-negative bacteria. results of the 374 isolated, 134 were imipenem resistant, and 240 were sensitive to imipenem. the resistance rate was more common in males and in pa...
