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...

conclusions the present study showed that bla oxa-23-like was the most frequent carbapenemase identified among carbapenem-resistant a. baumannii isolated in tehran hospitals. evaluation of antibiotic resistance genes in a. baumannii, is necessary to control further dissemination of these antibiotic resistant genes. results results showed that 123 of 131 (93.89%) acinetobacter species, possessed...

background & objective: urinary tract infection (uti) is a common disease in adults that early diagnosis and proper treatment of it has high importance. this study was performed for analysis of type and antibiotics resistance of isolated bacteria from urine of adult in different sex and ages for help in choose of antibiotics in empirical therapy.method: data of patients (gender, age, kind o...

conclusions the simultaneous detection of e. faecalis in a patient’s gastrointestinal and urine tracts can indicate the presence of uropathogenic enterococcus. further study is essential to identify virulence factors involved in the colonization of these isolates in the urinary tract. background urinary tract infection (uti) is one of the most common bacterial infections in outpatient settings....

conclusions although different source of p. aeruginosa may involve in patient colonization, genetically related strains were isolated from different wards and or the same ward of the hospital. our results pointed to the restriction of currently used antibiotics in studied hospital. we hope that our results cast light on the control and transmission of the infection in the investigated hospital....

BACKGROUND Enterococci are opportunistic pathogens and are a major factor in nosocomial infections. They may contain ebp operon, which upon expression makes them highly prone to biofilm formation on biotic and abiotic surfaces. OBJECTIVES The aim of the current study was to detect the polymorphism of ebp genes in Enterococcus faecalis. MATERIALS AND METHODS Samples were isolated from patien...
