OBJECTIVES Integrons are thought to play an important role in the spread of antibiotic resistance. This study investigates class 1 and 2 integron-positive methicillin-resistant coagulase-negative staphylococci strains isolated in Iran and characterizes their patterns of antimicrobial resistance. METHODS Hundred clinical isolates of coagulase-negative staphylococci were characterized for integ...
Resistance to various antimicrobial agents is an increasing problem in Pseudomonas aeruginosa and Acinetobacter baumannii infections. In this study, the roles of integrons were examined in 101 P. aeruginosa isolates and 176 A. baumannii isolates from patients. The frequencies and characteristics of class 1, 2 and 3 integrons were investigated and the horizontal transfer of integrons was assesse...
The increase in the prevalence of carbapenem-resistant Pseudomonas aeruginosa isolates, particularly caused by the metallo-ß-lactamases (MBL) is of great concern in the clinical settings worldwide. Here, we report the detection and identification of MBL producing P. aeruginosa in our hospital (University Malaya Medical Center, Malaysia), and the characterization of MBL cassette-containing integ...
Background and purpose: Due to the emergence of antibiotic resistance bacteria, treatment of urinary tract infection is becoming more problematic. Integrons are mobile genetic elements that play an important role in dissemination and accumulation of resistance genes of multidrug resistance in bacteria. The aim of the present study was to determine the antibiotic resistant profile, frequency of ...
Background and Objectives: The major mechanisms which contribute to the spread of shigellosis are antibiotic resistance and transmission from person to person. The main purpose of this study was determination of antibiotic susceptibilities and survey of the prevalence of integrons class I and II genes in Shigella species isolated from patients in Kerman hospitals Materials and Methods: I...
Background & Objective: Gastroenteritis is one of the most common Salmonella infections in human which is caused by Salmonella serotypes especially S.enteritidis and S.typhimurium. The spread of multi-drug resistant (MDR) Salmonella strains is a serious global issue. Obtaining integrons is considered as one of the most important factors in multi-drug resistance among gram-negative microorganism...
Background: Extended spectrum beta lactamases (ESBLs) are an important cause of transferable multidrug resistance (MDR) in gram-negative bacteria. The most described ESBL genes are generally found within integron-like structures as mobile genetic elements. The aim of this study was to identify the accompanying of class 1 integrons and ESBLs in the MDR E. coli isolates. Methods: Susceptibility t...
OBJECTIVES Antimicrobial resistance and class 1 integrons found in Escherichia coli isolates from humans and animals in Korea were characterized. METHODS E. coli isolates were examined for susceptibility to antimicrobial agents. Integrase genes were amplified. Gene cassette regions for classes 1 and 2 integrons were amplified and sequenced. Conjugal transfer and Southern hybridization were pe...
The Acinetobacter baumannii clonal complex 113/79 (CC113/79) and class 2 integrons predominate in Latin America; a relationship between these characteristics was explored. The presence of integrases was determined in successive hospital Acinetobacter isolates (163 A. baumannii isolates and 72 Acinetobacter nosocomialis isolates). Most isolates had integrons, but class 1 and 2 integrons were pre...
background: extended spectrum beta lactamases (esbls) are an important cause of transferable multidrug resistance (mdr) in gram-negative bacteria. the most described esbl genes are generally found within integron-like structures as mobile genetic elements. the aim of this study was to identify the accompanying of class 1 integrons and esbls in the mdr e. coli isolates. methods: susceptibility t...
