Hemolymph Microbiomes of Three Aquatic Invertebrates as Revealed by a New Cell Extraction Method.

ABSTRACT: Symbiotic microorganisms have been found in the hemolymph (blood) of many aquatic invertebrates, such as crabs, shrimp, and oysters. Hemolymph is a critical site in the host immune response. Currently, studies on hemolymph microorganisms are mostly performed with culture-dependent strategies using selective media (e.g., thiosulfate-citrate-bile salts-sucrose [TCBS], 2216E, and LB) for enumerating and isolating microbial cells. However, doubts remain about the "true" representation of the microbial abundance and diversity of symbiotic microorganisms in hemolymph, particularly for uncultivable microorganisms, which are believed to be more abundant than the cultured microorganisms. To explore this, we developed a culture-independent cell extraction method for separating microbial cells from t
