Two distinct forms are known in man, the African and the South American.South American trypanosomiasis, called Chagas' disease, is due to T. cruzi, man becoming infected by the bite of Lamas megistus, also known as Conorhinus megistus. The flagellates are found in the peripheral blood for only a comparatively short time after infection (two weeks in many cases). Then they pass into the internal organs and assume a leishmanial form, such forms producing pathologic lesions in the organs infested. The carrier of T. cruzi in Venezuela is Rodinus prolixus. When the disease attacks the nervous system, widespread spastic phenomena, diplegia, athetosis, flexure contractions and dementia are common, owing to the occurrence of the parasites in multiple foci throughout the brain. In the early stages the diagnosis can be made SN - 0002-9955 M3 - doi: 10.1001/jama.1929.92700290002011a UR - http://dx.doi.org/10.1001/jama.1929.92700290002011a ER -
