Abstract

To determine the effects of chitin (poly [1 -->4]-beta -N-acetyl-D-glucosamine) on the innate immune response of gilthead seabream (Sparus aurata L.), fish were fed diets containing 0 mg (control), 25, 50 or 100 mg kg(-1) chitin for 2, 4 and 6 weeks. Lysozyme and natural haemolytic complement activities, together with head-kidney leucocyte respiratory burst, phagocytic and cytotoxic activities, were studied at each of the assayed times. Lysozymeactivity was unaffected by the administration of chitin. The innate humoral and cellular immune response activities assayed were enhanced by the dietary intake of chitin, each increasing at a different time: natural haemolytic complement activity and cytotoxic activity after 2 weeks of treatment, respiratory burst activity from 4 weeks and phagocytic activity after 6 weeks, although, unlike the other activities, no statistically significant differences were observed in the first. The results indicate that chitin increases the activity of the seabream innate immune system, and its use as an immunostimulant is discussed, especially with regards to the protective role.
