conclusions due to the variable nature of antibiotic susceptibility patterns and etiological agents of septicemia, continual assessment of the most frequent pathogens associated with bloodstream infections and detection of their sensitivity patterns to locally available antibiotics seem to be reasonable measures. results from a total of 491 blood cultures, 74 (15.1%) samples were detected as po...

background neonatal sepsis is a serious problem in neonatal intensive care units, as it causes high rates of morbidity and mortality. objectives the purpose of this study is to evaluate various etiologic agents, antimicrobial susceptibility, clinical manifestations and the mortality rate in an intensive care unit in kashan, iran. patients and methods one hundred and four neonates with documente...

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 a 4...

b ackground: methicillin-resistant staphylococcus aureus (mrsa) is the one of most commonly isolated organisms from clinical samples which can cause life- threatening infections. the emergence and spread of antibiotic resistance makes the treatment of these infections more complicated. in this study, we aimed to determine  the  patterns  of  antibiotic  resistance  among  mrsa  isolates  from t...

backgrounds candida vaginitis is a common fungal infection among adult women and it has been estimated that 75% of all adult women experience at least one period of vulvovaginal candidiasis in their lifetime. several predisposing factors, such as diabetes mellitus,using contraceptive, pregnancy, and broad-spectrum antibiotics are reported as main risk factors for the infection. while, the main ...

conclusions the present study was the first report on the isolation and identification of t. ptyseos from pif in iran. t. ptyseos are frequently present in various kinds of foods; therefore, further investigation on these samples is required. it is necessary to track the t. ptyseos in a wide variety of foods and individuals especially in immunocompromised people such as human immunodeficiency v...

A survey of Genbank entries for complete microbial genomes reveals that the majority do not conform to the Genbank standard. Typical deviations from the Genbank standard include records with information in incorrect fields, addition of extraneous and confusing information within a field, and omission of useful fields. This situation results from two principal causes: genome centres do not submi...

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: Pelvic inflammatory disease is a clinical syndrome that has wide range of infections and inflammatory diseases of the upper female genital tract. Microbiological researches revealed that multiple bacteria have been identified as causative agents and several types of antibiotics are required to cover causative pathogens. The choice of an appropriate treatment mostly depended on antim...

Most evidence suggests that only a finite number of bacteria are responsible for dental caries and periodontal diseases. This knowledge led to the development of microbial tests which can identify suspected pathogens. Current evaluation of the diagnostic power of microbial tests has shown that they have a low sensitivity and a low prognostic value. Despite these shortcomings, there are valid in...
