Background: This study aimed to describe the association between age groups and antimicrobial susceptibility patterns, also integron presence in Escherichia coli and Klebsiella pneumoniae  isolates from Tabriz, Iran. Materials and methods: 140 isolates of E. coli and 150 isolates of K. pneumoniae, both comprising the same number of children and adult isolates were examined for susceptibil...

background: infections caused by pseudomonas aeruginosa or acinetobacter baumannii are of greatest concern for hospitalized patients, particularly those in intensive care units (icus). the aims of this study were to investigate the prevalence of integrons and biofilm formation among p. aeruginosa and a. baumannii isolates collected from icu and non-icu inpatients. materials and methods: a total...

The Arctic is one of the regions most affected by global climate change, and subjected to changes linked with a melting cryosphere increasing anthropopressure. Although antibiotic resistance problem, diversity spread antibiotic-resistant bacteria (ARB), genes (ARGs) integrons in are strongly understudied. Therefore, main aims this study (1) determination type frequency integron-integrase charac...

The Mhlathuze River has become a major reservoir for antibiotic-resistant microbes and a wide pool of antibiotic resistant genes with the environmental isolates exists in this water system. The ability of commensal organisms to carry resistant genes of clinical importance and their ability to transfer such genes to other bacteria are of greater concern than phenotypic measurements. Forty-three ...

The presence and genetic content of integrons were investigated for 37 epidemiologically unrelated multiple-drug-resistant strains of Salmonella enterica serotype Typhimurium from humans. All isolates were resistant to ampicillin, chloramphenicol, kanamycin, streptomycin, sulfonamides, and trimethoprim, as well as to tetracycline and/or nalidixic acid; 20% of them were also resistant to gentami...

The integron is a genetic element that incorporates mobile genes termed gene cassettes into a reserved genetic site via site-specific recombination. It is best known for its role in antibiotic resistance with one type of integron, the class 1 integron, a major player in the dissemination of antibiotic resistance genes across Gram negative pathogens and commensals. However, integrons are ancient...

A collection of 116 motile Pseudomonas spp. and 92 Aeromonas spp. isolated from 15 Vietnamese intensive catfish farms was analyzed to examine the molecular antibiotic resistance characteristics and the transferability of resistance markers within and between species. High levels of resistance to ampicillin, trimethoprim/sulfamethoxazole, nalidixic acid, chloramphenicol, and nitrofurantoin were ...

BACKGROUND Antimicrobial resistance among enteric bacteria in Africa is increasingly mediated by integrons on horizontally acquired genetic elements. There have been recent reports of such elements in invasive pathogens across Africa, but very little is known about the faecal reservoir of integron-borne genes. METHODS AND FINDINGS We screened 1098 faecal Escherichia coli isolates from 134 mot...
