EFFECT OF DIETARY ADMINISTRATION OF PORPHYRIDIUM CRUENTUM ON THE RESPIRATORY BURST ACTIVITY OF SOLE, SOLEA SENEGALENSIS (KAUP), PHAGOCYTES

The stimulatory effect of the red microalga Porphyridium cruentum on respiratory burst activity of sole phagocytes was evaluated in vivo. Oral administration of a diet supplemented with lyophilized P. cruentum cells (10 g kg)1) stimulated respiratory burst activity after 4 weeks feeding in sole vaccinated with Photobacterium damselae subsp. piscicida bacterin.
