This study reported the first confirmed case of epitheliocystis in
cultured juvenile striped trumpeter and showed that fish with
epitheliocystis had higher activity of blood serum lysozyme activity
and higher osmolality thus shedding some light on pathophysiology
of epitheliocystis. The lack of information on effects of epitheliocystis
on fish is due to the lack of challenge model and inability to culture
the causative agents.
