In the '''hepatitis form, micro-abscesses can also develop in the liver''' and in different species such as Japanese flounders, red sea bream Japanese eels and tilapia show predominantly '''granulomatous inflammation'''.

At least some ''E. tarda'' isolates produce ''toxic extracellular products (ECP)'' which may play a role in its virulence.  'E.tarda' '''haemolytic activity''' which is partially '''regulated by iron concentration''' could contribute to the pathogenicity of this bacteria to humans.
