Intestinal IgA Responses in G. lamblia-infected mice. Intestinal fluid was collected from the jejuna of 14-day-old infected c-kit+/+ (A) or c-kitw/wv (B) mice and used to stain trophozoites from in vitro cultures of G. lamblia. Fluorescein isothiocyanate-conjugated anti-IgA was used to demonstrate the presence or absence of IgA in the intestinal fluid, and propidium iodide (data not shown) was used to identify the parasites.
