A Brief Review of Oyster-associated Microbiota

Oysters are important mariculture species worldwide. Because of their filter-feeding behaviors, oysters contain complicated microbial populations, and these varying microbial populations can provide a correlation to increased oyster mortalities in the oyster farming industry as well as food outbreaks associated with public health surveillance. This review summarizes the significant outcomes in oyster microbiota research, including the identified oyster-associated bacterial taxa and comparison of different oyster tissues for microbial studies. In addition, environmental factors that could potentially affect the dynamics of oyster microbiota are discussed. Recent approaches developed to study oyster microbiota as well as their limitations are also highlighted in this review. Finally, future directions in oyster microbiota research have been suggested.
