ACHIEVEMENTS

Performed the first ultra structural studies on pathogenic protozoan (Trypanosoma, Toxoplasma & Plasmodium) 

Described structures such as cytoplasmic microtubules (1954) and the mitochondria-kinetoplast junction in many protozoan species   

With F.N. Guimarães described conoid organelle of Toxoplasma sp.

Developed methodology for the cultivation of Toxoplasma gondii in tissue culture being the first reproducible studies on it
