Growth of L. monocytogenes strain F2365 on ready-to-eat turkey meat does not enhance gastrointestinal listeriosis in intragastrically inoculated A/J mice
چکیده انگلیسی

There have been significant outbreaks of listeriosis associated with consumption of contaminated ready-to-eat (RTE) turkey meat products. In this study, we investigated whether growth on RTE deli turkey meat sends environmental signals to listerial cells that makes them more virulent in the gastrointestinal tract of mice. L. Listeria monocytogenes strain F2365 grew from a starting inoculum of 103 CFU/mL to final numbers of 108–109 CFU/mL (within 12 days at 10 °C) when inoculated onto sliced processed, or whole muscle, turkey breast, or into emulsified whole turkey breast. We did not observe any difference in the numbers of CFU recovered from the spleens and livers of A/J mice inoculated intragastrically with L. monocytogenes grown on sliced turkey meat, in emulsified turkey meat, or in brain heart infusion broth. These results suggest that growth on RTE sliced deli turkey, or in RTE emulsified deli turkey, does not enhance the ability of L. monocytogenes F2365 to cause gastrointestinal listeriosis in intragastrically challenged A/J mice.
