Investigação sobre imunologia da leishmaniose tegumentar americana. I — intradermo reação de Montenegro concomitante com antígenos de leptomonas pessoai e «l. brasiliensis"

Resumo

High specificity of an antigen obtained f rom Trypanosomatid — "Leptomonas pessoai" (Herpetomonas) Galvão, 1969, was observed in the intradermal test for cutaneous leishmaniasis. Besides specificity, a sensitivity similar to the homologous antigen normally used in the Montenegro reaction was found. 30 positive reactions were obtained in 30 patients with mucocutaneous leishmaniasis and in 64 patients with other diseases ten negative reactions, less than 5 mm were observed. In 8 cases these weakly positive reactions were concomitant with the two antigens, suggesting a probable cellular hypersensitivity by specific infection and the value of the simultaneous use of both antigens in epidemiologic surveys.
