These antibodies are IgD.
It is a monomeric antibody isotype that is expressed in the plasma membranes of immature B-lymphocytes. It is also produced in a secreted form that is found in small amounts in blood serum. IgD is co-expressed with IgM on the surface of the majority of mature B cells prior to antigenic stimulation and functions as a transmembrane antigen receptor.

Explanation:
Answer: during the course of infection the parasite, Giardia lamblia, pass through many anatomical locations to achieve its pathogenic effects which occurs in one host.
Explanation: infective form of the parasite is the mature cyst. Infection is acquired through ingestion of cysts in contaminated water or food. From the mouth the cyst passes down to the duodenum where it undergoes excystation. The cyst hatches out two trophozoites. By means of concavity on its ventral surface the trophozoites attaches to the epithelial lining of the small intestines. Encrustation occurs commonly in transit down the colon. Trophozoites retract the flagella into the axonemes, the cytoplasm becomes condensed and a thin tough hyaline cyst wall is secreted. As the cyst matures, the internal structures are doubled, so that when excystation occurs, the cytoplasm divides thus reproducing two trophozoites. Trophozoites are expelled through the anus with diarrhoeal stools.
