The addition of ox liver infusion greatly enhances the growth promoting properties of this medium while making it very poor as far as differentiation is concerned. With dog heart infusion instead of ox liver, the medium is still good for growth but not much better for differentiation. If, however, the pH of the dog heart infusion medium is lowered from 7.2 to 6.7, it continues to be good for growth and becomes excellent for differentiation.<\/jats:p><jats:p>Other factors were studied that stimulate or repress the rate of differentiation, such as preincubation at certain levels of temperature and the size and age of inocula.<\/jats:p>","DOI":"10.1111\/j.1550-7408.1967.tb02024.x","type":"journal-article","created":{"date-parts":[[2007,5,14]],"date-time":"2007-05-14T00:26:42Z","timestamp":1179102402000},"page":"447-451","source":"Crossref","is-referenced-by-count":130,"title":["Differentiation of <i>Trypanosoma cruzi<\/i> in Culture*"],"prefix":"10.1111","volume":"14","author":[{"given":"OLGA","family":"CASTELLANI","sequence":"first","affiliation":[]},{"given":"L.
