The host microbiota is associated with the occurrence and development of esophageal squamous cell carcinoma

DearEditor,Microecology is an emerging research area,particularly that of the digestive system(Marchesi et al.,2016;Wang et al.,2018).The intestinal microbiota contains a rich and complex microbial ecosystem that is in dynamic balance,the disruption of which can result in disease(Yatsunenko et al.,2012;Li et al.,2017;He et al.,2018).For example,studies have found that the esophagus has a variety of colonizing bacteria that may be related to esophageal cancer.
