[ 1 ] - تمایز بین سویه‌های مهاجم و آلوده‌کننده استافیلوکوکوس اپیدرمیدیس بر اساس Multiplex-PCR و بررسی فنوتیپی مقاومت دارویی

زمینه و اهداف: با افزایش عفونت‌های ایجادشده توسط استافیلوکوکوس اپیدرمیدیس، افتراق بین سویه‌های مهاجم و غیر مهاجم و تعیین الگوی مقاومت میکروبی در این سویه‌ها، ازنظر تشخیص و درمان، دارای اهمیت می‌باشد. مواد و روش کار: از شهریور 93 تا فروردین 94، تعداد 123 سویه جداشده از بیماران و تجهیزات پزشک از بیمارستان های حضرت رسول (ص) و حضرت علی اصغر(ع) با استفاده از ژن‌های ica، atlE، agrA، sarA و mecA به رو...

[ 2 ] - Characterization of Carbapenemases in Extensively Drug Resistance Acinetobacter baumannii in a Burn Care Center in Iran

The emergence of multidrug resistance (MDR) and extensively drug resistance (XDR) in Acinetobacter baumannii has made an important challenge in the treatment of infections caused by this organism. The ability of carbapenemase production is one of the main mechanisms for the emergence of MDR and/or XDR in A. baumannii. The aim of this study was to detect carbapenemase producer A. baumannii. In t...

[ 3 ] - Does biofilm formation have different pathways in Staphylococcus aureus?

Objective(s): Biofilm formation is one of the most important factors in the development of infections caused by Staphylococcus aureus. In this study, the expression levels of genes responsible for biofilm formation were studied in methicillin sensitive and methicillin resistant S. aureus.Materials and Methods: A total of 100 meticillin-r...

[ 4 ] - Evaluation of the genetic relatedness of Bacteroides fragilis isolates by TRs analysis

Objective(s): Human gastrointestinal tract harbors a variety of bacteria with vital roles in human health. Bacteroides fragilis is considered one of the dominant constituents of gut microflora which can act as an opportunistic pathogen leading to various diseases, including colon cancer, diarrhea, uterine and intrathecal abscesses, septicemia, and pelvic inflammation. ...

[ 5 ] - Antibiotic Susceptibility Pattern and Distribution of Virulence Factors Among Klebsiella pneumoniae Isolated from Healthy Volunteers

Background and Objective: The healthy people’s fecal flora in the community represents a large potential reservoir. Therefore, the current study aimed to detect antibiotic resistance patterns and virulence factors in Klebsiella pneumoniae isolated from healthy volunteers’ feces. Materials and Methods: Three hundred and fifty stool specimens were collected from sales rep healthy individuals ref...
