Pattern of immune response in recipients after transfer of mesenteric lymph node cells sensitized with low and high doses of Ancylostoma caninum.

Cellular immune response was detected in female Swiss albino mice with mesenteric lymph node cells during Ancylostoma caninum infection. Sensitized lymphocytes responded vigorously to A. caninum antigens and it was found that the cells (singly or repeatedly) sensitized with either low or high doses could confer adoptive protective immunity in recipients later challenged with a single dose of 500 A. caninum larvae.
