Try Fungizone (amphotericin B) from Biowhittaker.  I use a solution of
Pen/Strep/Fungizone at a dilution of 100ul/ml of cell culture medium to
prevent contamination in my virus isolations.  They say that this is an
alternative drug for the treatment of American cutaneous Leishmaniasis,
but it is not effective against L. donovani or L. tropica.  I do not have
any information about T. cruzi.  Hope this is useful, keep us posted.
