Comparative analysis of the intestinal bacterial communities in mud crab Scylla serrata in South India.

Little is known about the functions of the crustacean gut microbiome, but environmental parameters and habitat are known to affect the composition of the intestinal microbiome, which may in turn affect the physiological status of the host. The mud crab Scylla serrata is an economically important species, and is wild-caught, and farmed across the Indo-Pacific region. In this study, we compared the composition of the gut microbiome (in terms of gut microbial species richness and abundance) of S.
