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 ...

background : reports on the association of nosocomial bacterial infections with indwelling medical devices such as intravenous catheters (ivc) has increased in recent years. the potential to form biofilm on these devices seems to be the main reason for establishment of such infections. the aim of this study was to measure the potential of biofilm formation by bacterial isolates from ivcs. metho...

mammary secretions of 913 quarters from 229 pregnant holstein heifers were obtained aseptically to determine the prevalence of coagulase-negative staphylococci isolated during periparturient period. quarter samples were collected 14 to 10 days before expected parturition. analysis of culture data indicated that 78.5% (717/913) of samples were negative, 20.5% (187/913) contained coagulase-negati...

coagulase-negative staphylococci (cns) are a main cause of nosocomial infection. the main purpose of this study was to determination of frequency of cns isolates in in hospitalized patients and their susceptibility pattern to antimicrobial agents. during 11 month study, 65 cns clinical isolates were recovered from hospitalized patients in different wards of hospital. in vitro susceptibility of ...

coagulase-negative staphylococci (cons) have been identified as a major cause of nosocomial infections. nasal carriage of cons in nurses and physicians is known to be an important risk factor for potential hospital infections. this study was carried out to investigate the prevalence of nasal carriage of uncommon coagulase-negative staphylococci among nurse and physician staffs of tehran univers...

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 coagulase-negative staphylococci (cons) are opportunistic pathogens. methicillin resistance is common in cons and may play an important role as reservoir of staphylococcal cassette chromosome mec (sccmec) for staphylococcus aureus. objectives the aim of this study was to determine molecular characteristics of nasal carriage of methicillin-resistant coagulase negative staphylococci am...
