ABSTRACT

Inhibiçäo do crescimento de um subespécie de Leishmania por exometabólitos de outra subespécie, um fenômeno ainda näo notificado, é sugerido em nossas recentes observaçöes em experimentos de clonagem celular com Leishmania mexicana mexicana e Leishmania mexicana amazonensis. Os clones foram identificados usando a técnica de análise de esquizodemas. O fenômeno observado é claramente relevante em estudos de isolamento parasitário, metabolismo, imunidade cruzada e quimioterapia
