background and aims. although wearing a white coat is an accepted part of medical and dental practice, it is a potential source of cross-infection. the objective of this study was to determine the level and type of microbial contamination present on the white coats of dental interns, graduate students and faculty in a dental clinic. materials and methods. questionnaire and cross-sectional surve...

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 & Aims: Organisms producing TEM-β-lactamase are emerging around the world as a source of resistance to β-lactam antibiotics such as three generation cephalosporins. In this study, we used a polymerase chain reaction (PCR) to identify genes TEM for Extended-spectrum β-lactamase (ESBLs) producing clinical isolates of Klebsiella pneumonia from hospitals of Boro...

  Background and Objective: Urinary tract infection (UTIs) is one of the most common diagnosed infectious diseases. In order to determine the spectrum of bacterial etiology and antibiotic resistance pattern of the uropathogens that cause community acquired UTI, a retrospective study was performed in Research Center of Reference laboratories of Iran on urine samples of referred patients during ...

MOTIVATION The concentration of pathogen DNA in biological samples is often very low. Therefore, the sensitivity of diagnostic tests is always a critical factor. RESULTS We have developed a novel computational method that identifies species-specific repeats from microbial organisms and automatically designs species-specific PCR primers for these repeats. We tested the methodology on 30 random...

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...

INTRODUCTION Sepsis is a systemic inflammatory response related to high mortality rates in the hospital environment. Delayed etiological diagnosis and inadequate antimicrobial therapy are associated with treatment failures. Molecular tests based on polymerase chain reaction are regarded as faster and more accurate procedures than culture techniques for microbial identification, providing a high...

background: metronidazole, a 5-nitroimidazole derivative, is the main antitrich­omonal agent of  choice   for   treatment  of t richomoniasis . since 1962, s ome cases of treatment failure with metronidazole have been reported and recently drug re­sistance is now on the rise in the world. this study was aimed to determine current susceptibility of iranian isolates of trichomonas vaginalis to me...
