Ceratothoa verrucosa red seabream Pagrus major neutrophil morphology
We report the morphology and cytochemistry of new neutrophil types (fourth type, N-4^{th}; fifth type, N-5^{th}) from Ceratothoa verrucosa (Cv)- infested red seabream Pagrus major with morphological abnormalities. The number of Cv in each infested fish was one (usual parasitism). The N-4^{th} and N-5^{th} were observed in the infested fish with mouth insufficiency (MI; Mouth closure was incomplete) and with MI plus exophthalmos (ocular proptosis), respectively. The bulging eyes contained bubbles. The first (N-1^{st}), second (N-2^{nd}) and third (N-3^{rd}) neutrophil types have been reported from Cv-infested fish showing usual parasitism without morphological abnormality, unusual parasitism with MI, and super-unusual parasitism with MI plus exophthalmos, respectively. Therefore, the N-4^{th} and N-5^{th} will be the intermediate types (N-4^{th}, between N-1^{st} and N-2^{nd}; N-5^{th}, between N-1^{st} and N-3^{rd}).
