Trypanosomatid morphotypes from Leishmania spp, Trypanosoma cruzi and Trypanosoma brucei. Trypanosomatid forms are defined by cell shape, point of flagellum (f) emergence and position of the kinetoplast (k) in relation to the nucleus (n). For epimastigote, promastigote and amastigote forms, the kinetoplast is located in an anterior position relative to the nucleus, while for trypomastigote form the kinetoplast is located in a posterior position. Epimastigote and trypomastigote forms present an undulating membrane connecting to their flagella, once the flagellum is attached to the cell membrane, while other forms have a free flagellum, with the exception of amastigote forms, which presents a very small flagellum. In all morphotypes, only one large mitochondria (m) is observed, which is ramified through the cell body, being the region where the kinetoplast is located.
