A cluster of time-linked cases and the identification of a clonal strain suggest the occurrence of an outbreak of listeriosis in Belgium in 2011, presumably due to the consumption of hard cheese made with pasteurised milk and produced by a Belgium manufacturer. The outbreak clone was identified as Listeria monocytogenes serovar 1/2a, sensitive to arsenic and cadmium and of multilocus sequence typing MLST-type 37. Food investigation of this outbreak was facilitated by the European Epidemic Intelligence Information System and data exchanged between French and Belgium listeriosis surveillance systems.
一组时间关联病例和一株克隆株的鉴定表明，2011 年比利时发生了李斯特菌病暴发，可能与食用了比利时某生产商使用巴氏消毒牛奶生产的硬奶酪有关。暴发的克隆株被鉴定为李斯特菌 1/2a 血清型，对砷和镉敏感，多位点序列分型（MLST）类型为 37。通过欧洲传染病监测信息系统和法国与比利时李斯特菌监测系统之间交换的数据，有助于对此次暴发进行食品调查。
