Gene cassettes and cassette arrays in mobile resistance integrons.
Gene cassettes are small mobile elements, consisting of little more than a single gene and recombination site, which are captured by larger elements called integrons. Several cassettes may be inserted into the same integron forming a tandem array. The discovery of integrons in the chromosome of many species has led to the identification of thousands of gene cassettes, mostly of unknown function...
متن کاملInvestigating Class I, II and III Integrons in Multidrug Resistance in Pseudomonas aeruginosa Isolated from Hospital Infections in Ahvaz
Background and Aims: The indiscriminate use of antibiotics can lead to antibiotic resistance in the treatment of infections caused by bacteria such as Pseudomonas aeruginosa. The presence of integrons in Pseudomonas is clearly associated with multidrug resistances. Therefore, this study aimed at tracking class I, II and III integrons of antibiotic-resistant isolates of Pseudomonas aeruginosa th...
متن کاملAntimicrobial resistance and class I integrons in Salmonella enterica isolates from wild boars and Bísaro pigs.
The antibiotic resistance phenotype and genotype and the integron type were characterized in 58 Salmonella enterica isolates recovered from Bísaro pigs and wild boars (20 S. Typhimurium, 17 S. Rissen, 14 S. Enteritidis and 7 S. Havana). Most S. Typhimurium isolates (15/20 of Bísaro pigs and wild boars) showed ampicillin, chloramphenicol, streptomycin, tetracycline, sulfonamide, and amoxicillin-...
متن کاملDetection of gene cassettes in Tn402-like class 1 integrons.
Amplification of the gene cassettes in class 1 integrons by PCR using primers in the 5 conserved segment (5 -CS) and the 3 -CS (7, 8) has been used in hundreds of studies to identify integron-associated resistance genes (Fig. 1A). Equivalent PCR primers that detect cassettes in class 2 integrons, i.e., Tn7 family transposons (18), are also widely used. The approach used to detect integrons in a...
متن کاملGene cassette arrays, antibiotic susceptibilities, and clinical characteristics of Acinetobacter baumannii bacteremic strains harboring class 1 integrons.
BACKGROUND AND PURPOSE Acinetobacter baumannii isolates containing class 1 integrons belong to different clones, but only a few strains are successful at causing infection. This study was conducted to compare the characteristics among these clones with different epidemicity. METHODS Eighty eight bacteremic isolates of A. baumannii were collected in a medical center in Taiwan during a 3-year p...
