[ 1 ] - بررسی انتروباکتریاسه‌های تولیدکننده بتالاکتامازهای وسیع‌الطیف در فاضلاب‌های بیمارستانی
Background: Beta-lactams are the largest group of antibiotics used by hospitals to treat infections caused by Gram-negative bacteria. Enterobacteriaceae, natural microbiota of the human gastrointestinal tract, represent a large part of bacterial communities colonizing hospital effluents, and they could be a source of genes encoding extended-spectrum-beta-lactamases (ESBLs). Those genes may be tra…
[ 2 ] - بررسی مقاومت آنتی‌بیوتیکی باکتری‌های گرم منفی جدا شده از فاضلاب‌های بیمارستانی و الگوی پلاسمیدی سویه‌های مقاوم به چند دارو
Background: Waste effluents from hospitals contain high numbers of resistant bacteria. Among resistant strainsو Gram negative bacilli are able to survive for a long time in the environment and act as natural reservoirs of resistant genes. The aim of this study was to determine the prevalence of antibiotic resistant Gram negative bacilli and the plasmid profile of multi resistant bacteria in hospi…
[ 3 ] - جداسازی و شناسایی مولکولی یک Acinetobacter sp. مقاوم به آنتی‌بیوتیک از فاضلاب بیمارستانی و بررسی الگوی پلاسمیدی آن
Background: The emergence of antimicrobial-resistant genes and the indiscriminate use of antibiotics contribute to the dissemination of resistant pathogens in the environment. The objective of the present study was isolation and molecular identification of antibiotic resistant bacteria from the hospital sewage and investigation of the role of plasmid in resistance mechanism. Materials and Methods…
[ 4 ] - Determination of Antibiotic Resistance Pattern and frequency of CTX-M, TEM, and SHV Β-Lactamase Encoding Genes among Shigella Isolates from Inpatients in Tehran, Iran
ABSTRACT Background and Objectives: The emergence of extended-spectrum β-lactamase (ESBL)-producing Shigella spp. is becoming a health concern worldwide. This study aimed to investigate antibiotic resistance pattern and frequency of blaCTX-M, blaSHV, and blaTEM genes among Shigella isolates from patients in hospitals of Tehran, Iran. Methods: In this cross-sectional study, 52 non-repeated Shigell…
[ 5 ] - High Prevalence of CTXM-15 Type Extended-Spectrum Beta-Lactamase Among Clinical Isolates of Klebsiella Pneumoniae
Background: Production of β–lactamases by enterobacteriacea, especially Klebsiella pneumoniae, is one of the emerging health problems in the world. The purpose of this study was to assess the frequency of blaCTX-M15 gene in K. pneumoniae isolates and determine the molecular diversity of CTXM producing isolates. Methods: In this descriptive cross-sectional study, 100 K. pneumoniae strains were tes…
[ 6 ] - AmpC β lactamases in Urinary Klebsiella pneumoniae Isolates: First Report of ACC Type AmpC β-lactamase Resistance in Iran
Background & Objective: The production of plasmid-mediated AmpC beta-lactamases (PMABLs) among urinary Klebsiella pneumoniae isolates causes a severe problem to the successful treatment of urinary tract infections (UTIs). This study was designed to evaluate antimicrobial resistance, the presence of AmpC beta-lactamase genes, and the genetic relatedness among K. pneumoniae strains separated from p…
