Abstract Objectives Long-term care facilities (LTCFs) may act as a reservoir of ESBL-producing Enterobacterales (ESBL-E) and carbapenemase-producing (CPE) for hospitals the general population. In this study, we estimated prevalence molecular epidemiology rectal carriage with ESBL-E CPE in residents Dutch LTCFs between March 2018 December 2018. Methods were geographically selected across country...
افزایش شیوع بتا-لاکتامازهای وسیع الطیف (esbl) در اعضای خانواده انتروباکتریاسه یک مشکل بالینی جدی در جهان شده است. هدف این بررسی، مطالعه تیپ بندی ژنومی و تنوع ژنتیکی پیرامون ژن گروه blactx-m-1 در ایزوله های بالینی کلبسیلا پنومونیه بود. 200 ایزوله بالینی کلبسیلا پنومونیه میان فروردین و آذر 1390 از نمونه های بالینی مختلف در 3 بیمارستان شهر تهران (لقمان حکیم، امام خمینی و میلاد) جمع آوری و توسط آزم...
objective(s) different types of extended spectrum beta-lactamases (esbls) are encountered in the clinical settings worldwide. there are a few studies regarding the prevalence of esbl genes among klebsiella pneumoniae isolates at tehran especially those of blaper and blactx. the aim of this study was to determine the prevalence of blashv, blatem ,blaper and blactx genes among clinical k. pneumon...
This study aimed to determine the prevalence of fecal carriage of extended spectrum β-lactamase (ESBL) and/or plasmidic AmpC β-lactamase (pAmpC) producing Escherichia coli among dogs (n=428) in Turkey. Polymerase chain reaction (PCR) and sequencing were used to characterize genes encoding β-lactamase and plasmid mediated quinolone resistance (PMQR). Antimicrobial susceptibility testing and PCRs...
Extended-Spectrum Beta-Lactamase (ESBL)-producing bacteria are a common cause of healthcare and community-associated infections worldwide. The distribution of such isolates in the environment and their presence in fish as a result of sewage contamination is not well-studied. Here we examined fish and environmental samples from Mwanza city for the presence of ESBL-producing bacteria. From 196 fi...
The aim of this study was to detect the presence carbapenem resistant Escherichia coli (E. coli) in cattle and pigs. Altogether, 100 samples were collected, 50 each from pigs including mastitic milk faecal healthy as well diarrhoeic slaughter specimens Bacteria isolated antibiotic sensitivity test carried out. Eight isolates E. obtained 15 phenotypic resistance patterns against carbapenems (ert...
BACKGROUND Nosocomial infections caused by Pseudomonas aeruginosa presenting resistance to beta-lactam drugs are one of the most challenging targets for antimicrobial therapy, leading to substantial increase in mortality rates in hospitals worldwide. In this context, P. aeruginosa harboring acquired mechanisms of resistance, such as production of metallo-beta-lactamase (MBLs) and extended-spect...
OBJECTIVES Extended-spectrum beta-lactamase (ESBL) producing bacteria have an important role in nosocomial infections. Due to the limited availability of information about the molecular epidemiology of ESBL producing bacteria in Mashhad, we decided to investigate about TEM, CTX and SHV ESBLs among urinary Escherichia coli isolates in Mashhad, a city in northeast Iran. MATERIALS AND METHODS On...
Escherichia albertii is an emerging member of the Enterobacteriaceae causing human and animal enteric infections. Antimicrobial resistance among enteropathogens has been reported to be increasing in the past years. The purpose of this study was to investigate antibiotic resistance and resistance genes in E. albertii isolated from Zigong city, Sichuan province, China. The susceptibility to 21 an...
Klebsiella pneumoniae is a major cause of nosocomial infections. Emergence of antibacterial resistance and production of beta-lactamases are responsible for the frequently observed empirical therapy failures. The aim of this study was to determine the presence and the prevalence of extended spectrum beta-lactamases (ESBLs) and AmpC beta-lactamases in clinical isolates of K. pneumoniae in Kerman...
