Background: Acinetobacter baumannii is an important opportunistic pathogen which causes complications in hospitalized patients, especially those in ICU. The aim of this study was to determine the frequency of class 1 and 2 integrons in multi-drug resistance A. baumannii and to investigate the association between the presence of integrons and antibiotic resistance patterns. Methods: A total of...

The objective of this study was to characterize the gene cassettes of class 1 integrons and antimicrobial resistance among CTX-M-3-producing Serratia marcescens isolates from different specimens in southern Taiwan. One hundred and twenty-two isolates (70.5%) of 173 CTX-M-3-producing S. marcescens isolates were positive for class 1 integrons, including 53.3% of blood isolates, 94.1% of urine iso...

Background: Salmonella spp. are major causes of food-borne disease and have been identified among many diarrheal outbreaks. The major aim of the current investigation was to evaluate the class 1 and 2 integrons and antibiotic resistance pattern in Salmonella enterica isolated from diarrheal food-borne outbreaks in Iran.  Methods: This study was carried out on 115 diarrheal feces samples obtain...

OBJECTIVES To analyse the prevalence and diversity of integrons in faecal Escherichia coli isolates from healthy humans in Spain. METHODS One hundred E. coli isolates were obtained in Levine agar plates from faecal samples of 100 healthy humans during March to October 2007. Susceptibility to 16 antimicrobial agents was determined by the disc diffusion method. The presence and characterization...

BACKGROUND Due to the importance of antibiotic resistance in E.coli and the possible role of integrons in creating of resistance, this study was performed to survey of class 1 integron in E. coli strains and their resistance to three routinely used antibiotics. METHODS In this cross-sectional study, 100 strains of E. coli were isolated from patients with Urinary tract infection. After diagnos...

Of the 834 Salmonella spp. isolates collected from 2002 to 2004 in the New Territories East Cluster hospitals in Hong Kong, 21% were resistant to 3-14 antibiotics and 30% were resistant to nalidixic acid with reduced susceptibility to ciprofloxacin. A class 1 integron was present in 105 (13%) isolates, of which more than 50% were Salmonella Typhimurium. Class 2 or 3 integrons were not detected ...

The study evaluated the association between evolutionary relationship and the protein structure of class 1 integron-coded proteins of Citrobacter freundii and Serratia marcenscens. The prediction of the secondary structure of the class 1 integron coded protein was carried out using SOPMA tool. Results of the NCBI queries revealed significant identity with class 1 integron of the studied organis...

A total of 21 (4.3%) enterohemorrhagic E. coli strains were isolated by biochemical tests and identification of the eae(+)stx1(+)stx2(+) genotype from 490 stool samples obtained from calves with diarrhea during 1-year period from a major farm in Tehran, Iran. All of the strains showed resistance to ampicillin, ciprofloxacin, trimethoprim, streptomycin, chloramphenicol and tetracycline, while 19...

This study was aimed to find out that broiler chicken farms have problems with antibiotic resistance Citrobacter freundii and determined the prevalence class 1 integron encoding gene. Multidrug collected from among one hundred sixty cloacal swab samples 32 in Blitar for 3 months. The method of bacterial inoculation used MacConkey agar biochemical test conducted by IMViC TSIA test. sensitivity p...
