Toxigenicity and genetic diversity of Staphylococcus aureus isolated from Vietnamese ready-to-eat foods

摘要: The aim of this study was to investigate the prevalence and genetic diversity Staphylococcus aureus staphylococcal enterotoxins (SEs) in ready-to-eat foods marketed Hanoi, Vietnam. Out 212 samples tested, 45 were contaminated with bacterium 18 contained strains having classical SEs. Among different food products, bacterial occurrence ranged between 12.5% 35.4% milk had highest prevalence. production SEs varied according types 26 ribotype patterns observed among strains. Our dendogram analysis showed existence many clones without clear-cut affiliation any particular type indicating both diverse primary secondary contamination sources. also occurred a wide variety genetically S. which might facilitate better ecological fitness cause epidemics. It can be concluded that Vietnamese pose high risk by toxigenic population urging need implementing proper hygienic practices.
