The abilities of certain microorganisms to be transferred across the food production chain, persist in the final product and, potentially, colonize the human gut are poorly understood. Here, we provide strain-level evidence supporting that dairy cattle-associated bacteria can be transferred to the human gut via consumption of Parmesan cheese. We characterize the microbial communities in samples taken from five different locations across the Parmesan cheese production chain, confirming that the final product contains microorganisms derived from cattle gut, milk, and the nearby environment. In addition, we carry out a human pilot study showing that Bifidobacterium mongoliense strains from cheese can transiently colonize the human gut, a process that can be enhanced by cow milk consumption.
某些微生物能够在食品生产链中转移、在最终产品中持续存在，并有可能在人类肠道中定植，这方面的知识还很有限。在这里，我们提供了菌株水平的证据，支持食用帕尔马干酪会将与奶牛相关的细菌转移到人类肠道中。我们对帕尔马干酪生产链中五个不同地点的样本中的微生物群落进行了特征描述，证实最终产品中含有源自牛肠道、牛奶和附近环境的微生物。此外，我们进行了一项人类初步研究，表明奶酪中的双歧杆菌属蒙古亚种可以暂时定植于人类肠道，而这一过程可以通过饮用牛奶得到增强。
