Bivalves are filter-feeders that can accumulate large numbers of bacteria, in particular Vibrio
species; these can persist within bivalve tissues largely depending on their sensitivity to the
hemolymph bactericidal activity. In this work, functional parameters of the hemolymph of
Mytilus galloprovincialis were evaluated in response to in vivo challenge with different
bacteria (Gram (−) Vibrio anguillarum and V. splendidus, Gram (+) Micrococcus
lysodeikticus). Mussels were injected with heat-killed bacteria or PBS-NaCl (controls) and …
