Molluscan shellfish parasites

While all humans have IgE antibodies fhaf are involved in defense against parasitic infections, only humans who are predisposed to the development of allergies will produce IgE antibodies upon exposure fo certain protein allergens present in their environment including their diet. Only a few of the many proteins found in foods are capable of sfimulating the production of specific IgE antibodies in susceptible individuals (Taylor, 2002). With molluscan shellfish, only one, or perhaps a few, of the numerous proteins is known to provoke the production of IgE antibodies that specifically recognize one or more species of molluscan shellfish.

Methods for identification of human protozoan parasites in the tissue of molluscan shellfish include (1) immunofluorescent antibodies (IFA) alone or in combination with immunomagnetic separation (IMS), (2) polymerase chain reaction (PCR) alone or combined with restricted fragment length polymorphism (RFLP) for genotyping, (3) multiplexed nested PCR, and (4) fluorescence in situ hybridization (FISH). Infectivity of the parasites recovered from the shellfish are usually assessed by mouse bioassays. [Pg.91]

Development of new molecular techniques that can be applied to a wide variety of food items has dramatically increased the sensitivity and specificity of detection of human enteric parasites in the tissue of molluscan shellfish (Schwab et al., 1998, 2000 citations in Table I). [Pg.93]
