Abstract
The ability of rainbow trout, Oncorhynchus mykiss (RBT), to produce a localized mucosal immune response was investigated following intraperitoneal (i.p.) or peranal (p.a.) immunization with a protein-hapten carrier, fluorescein isothiocyanate conjugated to keyhole limpet haemocyanin (FITC/KLH). Antibody levels in serum, mucus, tissue culture supernatant from blood and spleen leucocytes, and excised skin, intestine and gill tissues were determined by ELISA. Significantly, elevated antigen-specific antibodies were elicited in both serum and mucus of fish immunized i.p. Mucosal antibody responses, in general, paralleled serum responses over time. Leucocytes isolated from spleen and blood of i.p. immunized fish at week 10 produced significantly elevated antibody levels against FITC when cultured in vitro. Excised skin, intestine and gill tissues from these fish also exhibited significantly elevated antibody responses indicating localized production in the mucosa from tissue-specific B cells. A localized mucosal immune response was elicited only after i.p. and not p.a. immunization, suggesting that systemically stimulated B cells migrate to mucosal tissues where they produce antibodies locally.
