Dynamics of <i>Vibrio ostreicida</i> in <i>Mytilus galloprovincialis</i> through <i>in vivo</i> infections.

ABSTRACT:

Introduction

Vibrio species are widespread in coastal environments, where they are being increasingly associated with mortality episodes of farmed bivalves. This is the case for Vibrio ostreicida strain r172 isolated from a mortality event of adult mussels Mytilus galloprovincialis in Spain in 2022.

Methods and results

In this study, the infection dynamics and immune responses of adult M. galloprovincialis challenged with V. ostreicida r172 were investigated using different in vivo experimental approaches. First, a virulence assay by injection (1 x 108 CFU/100 µL) was performed at different temperatures (12, 18 and 24 °C). The results showed that mussel mortality (about 50 % within 8 days) was independent of increasing temperatures.
