Description
Summary:This experiment was done to determine if transmission of Trichinella spiralis larvae could be accomplished through arctic marine invertebrates as mechanical hosts. Marine Crustacea (amphipods and shrimps) were trapped in the Chukchi Sea, held in aerated tanks of sea water, and fed on glycerin-preserved trichinous rat muscle. Following exposure, Crustacea were held for various periods, then cryopreserved for later examination in the laboratory. Larvae were found in the alimentary canals of seven crustacean species. Their ability to persist within such invertebrates for as long as 28 h lends support to the hypothesis that Crustacea might act as mechanical transmitters of Trichinella to fish and invertebrate-eating marine mammals.
