Abstract

Thirteen Listeria monocytogenes strains were compared for the ability to survive in a dynamic gastrointestinal model. Strains displayed various degrees of susceptibility to gastric acidity; however, strain-to-strain variations became evident mainly after 90 min of exposure (pH 2.0). Cell levels transferred to the intestine depended on initial populations, while reductions during intestinal exposure were relatively small for all strains.

摘要

对13株单核细胞增生李斯特菌在动态胃肠道模型中的存活能力进行了比较。各菌株对胃酸的敏感性各不相同；然而，菌株间的差异主要在暴露90分钟（pH 2.0）后才明显显现。转移至肠道的细胞数量取决于初始菌量，而在肠道暴露期间，所有菌株的菌量减少相对较小。
