conclusions according to these findings, antibiotic-resistance patterns have changed, and vancomycin resistance, especially among e. faecium, is rising because of nosocomial infections. consequently, it has become a serious subject for patients admitted into a hospital. results a total of 53 enterococci were isolated from clinical samples of blood, urine, wounds, sputum, and cerebrospinal fluid...

background and objectives: bacterial bloodstream infections (bsis) and surgical site infections (ssis) are among the most common nosocomial infections with high mortality and morbidity. we aimed to evaluate the frequency of various species among bsis and ssis at tehran heart center, tehran, iran. methods: patients with localized or systemic infections that became evident 48 hours or more after ...

background and objective:  early diagnosis of streptococcus agalactiae remains difficult, since symptoms are very nonspecific. its frequency has not been completely investigated in urinary tract pathogen of pregnant ant and non pregnant women in iran. the aim of this study was determining the frequency of group b streptococci in female patients. materials and methods: a total of 11800 urine sp...

conclusions due to the low frequency of stec o157 and the high susceptibility rates of the isolates to the tested antibiotics in this study, stec o157 has not become a major problem in tabriz yet, but comprehensive microbiological surveillance programs that provide early warning and limit the scale of possible outbreaks would be essential. results of the isolates 11 (5.5%) were sorbitol-negativ...

Background Choosing a unique empiric treatment for ventilator associated pneumonia (VAP) can be challenging. We aimed to determine the antimicrobial susceptibility pattern of Intensive Care Unit (ICU) of the only referral pediatric hospital in Isfahan in order to design the optimal empiric treatment protocol. Materials and Methods: </strong...

Enterococcus is the second cause of urinary tract infections in hospitals and the third most common cause of nosocomial bacteremia. Overuse of antibiotics for the treatment of nosocomial infections, causes antibiotic resistance in enterococci resistant to antibiotics through their ability to acquire resistance to antibiotics through mutation or acquisition of genetic material carrying a resista...

background and objectives: methicillin-resistant staphylococcus aureus (mrsa) is a well-known pathogen with a worldwide distribution. given the increasing rate of mrsa infections, implementing of reliable, accurate and rapid testing for diagnosis of mrsa is necessary. the aim of this study was to compare four diagnostic methods for detection of mrsa isolates. materials and methods: from decembe...

conclusions: silver nanoparticles showed great antibacterial effectiveness on four important foodborne pathogens. therefore, ag nps could be a good alternative for cleaning and disinfection of equipment and surfaces in food-related environments. results: the mic values of ag nps against tested pathogens were in the range of 3.12-6.25 µg/ml. while listeria monocytogenes showed the mic value of 6...
