Serum supplies stearic acid, essential for the growth of this trypanosome. A liquid heat-sterilizable medium, composed of peptone and known chemicals is described. The growth of T. cruzi in this medium reached 70 x 106 trypanosomes/ml., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-31-2-261
