[Immunocyte adherence and leukocyte migration inhibition tests in dogs infested with Leishmania donovani. Importance of lymphocyte conservation in liquid nitrogen].
A method of canine lymphocytes isolation and storage in liquid azote with DMSO is described. It was possible to use these lymphocytes in the immunocytoadherence and leucocytes migration inhibition tests in dogs infected with Leishmania donovani. The sensitisation was made with a soluble antigen from promastigotes of L. donovani braid by ultrasounds. The dogs with Leishmaniasis gave positive results. The controls without Leishmaniasis were negative. The tests with conserved lymphocytes were as satisfactory as the same tests with fresh lymphocytes.
