SERUM IgE LEVEL IN MICE INFECTED WITH SINGLE DOSES OF ANCYLOSTOMA CANINUM LARVAE
- V. VIVEKA, Viveka Vardhani
Eosinophil changes in the peripheral blood of singly and repeated infected mice were studied during murine ancylostomiasis. In singly infected animals, eosinophils began to rise on 1st day, reached a peak on 4th day and progressively declined from 9th to 30th day. In repeatedly infected animals, peak eosinophilia was observed during 3rd week of post infection and sustained upto 30th day with a slight decrease. These studies demonstrate that eosinophilia is induced due to antigen-antibody reactions in the host system and eosinophilia in helminthic infections is amnestic response.
