“…The results in this study show that multidrug-resistance is common in Salmonella isolates from poultry and swine, which are similar to those previously reported in Thailand [4,20] and from other countries [7,9,13]. High proportions of resistant S. enterica from swine and poultry were in agreement with a recent study conducted in Thailand that reported the highest resistance rate in Salmonella spp.…”

“…at the farm [20]. Low levels of ciprofloxacin resistance were observed, which was comparable to other studies of humans and foods [4,14]. However, the prevalence of ciprofloxacin resistance from this study was slightly higher in comparison to the earlier study in farm sectors, where no resistance to the agent was found [20].…”

ABSTRACT. Salmonella enterica isolates from poultry (n=125) and swine (n=132) in Thailand were investigated for antibiotic resistance, susceptibility to disinfectants (benzalkonium chloride (BKC), chlorhexidine digluconate (CHX), zinc chloride and copper sulfate) and cyclohexane tolerance. Forty-two percent were of multiple resistance to antibiotics. The minimum inhibitory concentrations (MICs) of all antibiotics against isolates from swine were higher than that against the isolates from poultry. There were generally few variations in MICs to all disinfectants, indicating that the isolates had either no or only a limited degree of developed resistance to the disinfectants tested. Only 5 isolates (1.9%) were tolerant to cyclohexane. The proton-dependent efflux systems did not play a major role in the reduced susceptibility to BKC and CHX, since susceptibility was not restored when an efflux inhibitor, carbonyl cyanide m-chlorophenylhydrazone (CCCP) was present. Successive exposure to subinhibitory concentrations of BKC and CHX generated mutants resistant to BKC and CHX. A spontaneous BKC-resistant derivative expressed cross-resistance to antibiotics, chloramphenicol and erythromycin. The mechanism responsible for cross-resistance between BKC and antibiotics was not driven by the proton motif force (PMF). KEY WORDS: benzalkonium chloride, multiple antibiotic resistance, Salmonella enterica, proton-dependent efflux system.

A potential epidemic clone of Salmonella enterica serotype Typhimurium DT104, and the possible emergence of S. enterica serotype Typhimurium DT104b, has been identified from the characterization of 67 S. enterica serotype Typhimurium strains from three sources, human gastroenteritis isolates, isolates from food samples, and veterinary isolates, by antimicrobial resistance profiling, phage typing, and pulsed-field gel electrophoresis. Resistance to ampicillin, chloramphenicol, streptomycin, sulfonamides, and tetracycline was found in 77.6% of these strains.
