Host-microbiota interactions and responses of Metapenaeus ensis infected with decapod iridescent virus 1.

ABSTRACT:

Introduction

Decapod iridescent virus 1 (DIV1) has caused severe economic losses in shrimp aquaculture. So far, Researchs on DIV1-infected shrimp have mainly focused on the hemocytes immune response, while studies on the host-intestine microbiota interactions during DIV1 infection have been scarce.

Methods

This study determined the lethal concentration 50 (LC₅₀) of DIV1 to Metapenaeus ensis, preliminarily determining that M. ensis could serve as a susceptible object for DIV1. The interactions and responses between the immune and intestine microbiota of shrimp under DIV1 infection were also investigated.

Results and discussion

DIV1 infection decreases intestine bacterial diversity and alters the composition of intestine microbiota. Specifically
