We evaluated the detection of Listeria spp. using MALDI-TOF MS directly in enrichment broths, without isolated colonies, with naturally contaminated food and stool samples. The success rate was 77%. Considering the reduced time for diagnosis and the success rate, this is a promising screening tool, but more tests are needed to determine its viability.

评价MALDI-TOF MS作为检测李斯特菌的工具。直接来自食物和粪便样品的选择性富集肉汤。

我们评估了李斯特菌属的检测。将MALDI-TOF MS直接用于富集肉汤中,而无需分离菌落,并带有自然污染的食物和粪便样品。成功率为77%。考虑到减少的诊断时间和成功率,这是一种很有前途的筛选工具,但是需要更多的测试来确定其可行性。
