Regarding the economic importance of bivalve farming, a great deal of interest has recently been devoted to studying the pathogenesis of infectious diseases of these mollusks to prepare for public health emergencies.
is one of these pathogens; it is a ubiquitous soil bacterium responsible for many types of gastrointestinal diseases associated with food. This study was conducted to determine the pathogenic effect of
on
. This effect was studied by assessing hemocytes death using flow cytometry analysis. The results showed that only ∼15% of
were able to survive after
artificial infection with 10
CFU (colony-forming unit)/oyster. Evenly, the percentage of nonviable hemocytes gradually increased with the concentration of
, with a peak value of ∼40% after infection. Indeed, findings showed that this strain is harmful to
