摘要

A substantially pure lectin for prevention and treatment of crustaceous infected by baculovirus, a food composition containing the lectin and a method for increasing the crustaceous resistance to infections. The lectin is isolated from the species Macrobrachium rosenbergii, and it has the aminoacid sequence SEQ ID No. I, wherein the complete sequence or part thereof is employed for elaborating a food composition for treating the water of a prawn breeding station, in a manner to prevent and/or cure the prawn infected by the baculovirus that causes the “White spot” syndrome.
