Efeitos de fatores humorais do camundongo tratado com Trypanosominum TC D30, em testes de lise do Tripanosoma cruzi "in vitro" / Humoral factors effects im mice treated with in lysis test of T. cruzi "in vitro"

Utilizando-se soros imune e de animais tratados com Trypanosominum TC D30, em presenca de complemento, observa-se que ocorre a lise de tripomastigotas sanguineos da cepa Y. Quando os referidos soros sao adicionados de soro humano normal inativado, os tripomastigotas sanguineos nao sao lisados. A lise de tripomastigotas mediada por complemento, revela a presenca de anticor-pos liticos no soro imune e no soro de camundongos tratados com o TrypanosominumTC D30, sugerindo a resistencia do hospedeiro contra o T. cruzi

Utilizacao de soros de camundongos e ratos tratados com bioterapico D30 em reacoes de aglutinacao com T. Cruzi / T. Cruzi aglutination reactions utilizing mice serum treated with biotherapic D30

The trypomastigotes were aglutinated by imune animals serum in several dilutions. However, when treated with biotherapic D30, the trypomastigotes were not aglutinate by all dilutions utilized. When diluted 1:2 rat serum aglutination ocorred. The results suggest: the presence of aglutinating antibodies appear soon and is related with the control of the acute phase of humoral immunity
