This study was conducted to examine the rate of contamination and the molecular characteristics of enteric bacteria isolated from a selection of food sources in Vietnam. One hundred eighty raw food samples were tested; 60.8% of meat samples and 18.0% of shellfish samples were contaminated with Salmonella spp., and more than 90% of all food sources contained Escherichia coli. The isolates were screened for antibiotic resistance against 15 antibiotics, and 50.5% of Salmonella isolates and 83.8… CONTINUE READING

Sequencing results revealed that the integrons harbored various gene cassettes , including aadA1 , aadA2 , and aadA5 ( resistance to streptomycin and spectinomycin ) , aacA4 ( resistance to aminoglycosides ) , the dihydrofolate reductase gene cassettes dhfrXII , dfrA1 , and dhfrA17 ( trimethoprim resistance ) , the beta - lactamase gene bla(PSE1 ) ( ampicillin resistance ) , and catB3 ( chloramphenicol resistance ) .

Our results show that enteric bacteria in raw food samples from Vietnam contain a pool of mobile genetic elements and that the transfer of antibiotic resistance can readily occur between similar bacteria .

The isolates were screened for antibiotic resistance against 15 antibiotics , and 50.5% of Salmonella isolates and 83.8% of E. coli isolates were resistant to at least one antibiotic . Isolates were examined for the presence of mobile genetic elements conferring antibiotic resistance .
