Detection and characterisation of integrons in Salmonella enterica serotype enteritidis.

Drug resistance genes encoded in integrons and in extra-integrons: their distribution and lateral transfer among pathogenic enterobacteriaceae including enterohemorrhagic Escherichia coli and Salmonella enterica serovars typhimurium and infantis.

Expanding drug resistance through integron acquisition by IncFI plasmids of Salmonella enterica Typhimurium.

We conducted a 30-year retrospective analysis of IncFI plasmids from Salmonella enterica serotype Typhimurium. These plasmids have been associated with the emergence of epidemic clones of multidrug-resistant Salmonella. Molecular and genetic evidence indicates that IncFI plasmids are evolving through sequential acquisition of integrons carrying different arrays of antibiotic- resistance genes.

Integron-associated antibiotic resistance in Salmonella enterica serovar typhi from Asia.

Eighteen of 25 isolates of Salmonella enterica serovar Typhi were multidrug resistant and contained class 1 integrons with a single cassette, dfrVII or aadA1. The dfrVII-containing integron was likely borne on an IncHI1 plasmid. Salmonella serovar Typhi could become resistant to broad-spectrum cephalosporins by integrating cassettes, such as veb-1, a common cassette in Asia.

Molecular characterization of Irish Salmonella enterica serotype typhimurium: detection of class I integrons and assessment of genetic relationships by DNA amplification fingerprinting.

Salmonella enterica is among the principal etiological agents of food-borne illness in humans. Increasing antimicrobial resistance in S. enterica is a cause for worldwide concern. There is concern at present in relation to the increasing incidence of human infection with antimicrobial agent-resistant strains of S. enterica serotype Typhimurium, in particular of phage type DT104. Integrons appea...

Evaluation of Class 1 and 2 Integrons and Antibiotic Resistance Pattern in Salmonella enterica Isolated from Diarrheal Food-Borne Outbreaks in Iran

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...
