Abstract: The recognition that animals develop immunity to a wide range of protozoan and helminth parasites first began about 80 years ago with the observations of Smith and Kilbourne (1893) that cattle recovered from Texas fever (Babesia bigamina) were immune to subsequent infection. This was followed by reports of acquired immunity in various helminth infections including trichinosis (Ducas, 1921) strongyloidosis (Sanground, 1928), haemonchosis (Stoll, 1928; 1929) and nippostrongylosis (Africa, 1931). In general, the early work concerned with the immunological reactions of hosts to helminth infection, dealt mainly with the development and improvement of procedures for the immunodiagnosis of helminthosis (e.g., the intradermal test for human hydatidosis developed by Casoni in 1911), and this particular aspect of host immunity has been reviewed by Fife (1971). More recently, the elucidation of the manifestations and mechanisms of host resistance to helminth infection has received increasing attention…
