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...
متن کاملSerotype Distribution and Antimicrobial Resistance of Salmonella Isolates in Human, Chicken, and Cattle in Iran
Salmonellais a foodborne zoonotic enteric bacterium able to infect both humans and animals. This study aimed to identify the antimicrobial resistance of Salmonella serovars isolated from human, cattle, and poultry. Moreover, we investigated the probable transmission trends of antibiotic-resistant Salmonella isolates from food animals to human. A total of 242 Salmonella isolates collected from v...
متن کاملDetection of the class 1 integrons and SGI1 among Salmonella enterica Serovar Typhimurium DT104, U302, DT120, DT193, and nontypable human isolates.
Salmonella enterica serovar Typhimurium strains of particular phage types, such as DT104, U302, DT120, DT193, and nontypable strains, are often characterized by resistance to multiple antibiotics. This antibiotic resistance can be caused by the presence of the integrons, transposons, Salmonella genomic island 1 (SGI1), or conjugative plasmids. In this study we were interested in the relative co...
متن کاملAntibiotic resistance genes, integrons and multiple antibiotic resistance in thirty-five serotypes of Salmonella enterica isolated from humans and animals in the UK.
OBJECTIVES To examine 397 strains of Salmonella enterica of human and animal origin comprising 35 serotypes for the presence of aadB, aphAI-IAB, aadA1, aadA2, bla(Carb(2)) or pse1, bla(Tem), cat1, cat2, dhfr1, floR, strA, sul1, sul2, tetA(A), tetA(B) and tetA(G) genes, the presence of class 1 integrons and the relationship of resistance genes to integrons and antibiotic resistance. RESULTS So...
متن کاملCharacterization of antimicrobial resistance and class 1 and 2 integrons in Salmonella enterica isolates from different sources in Portugal.
OBJECTIVES The antimicrobial resistance profiles of 1183 Salmonella isolates collected during 2002-2003 from several sources (human, food products and environment) were evaluated. The occurrence, distribution and cassette content of class 1 and 2 integrons among the sulphonamide-resistant population, as well as the role of particular clones to the spread of these genetic elements, were investig...
