Question

After a sandfly has ingested macrophages containing the amastigotes of Leishmania, which of the following events takes place? The amastigotes go through a series of divisions culminating in the production of metacyclic trypomastigotes. The amastigotes fuse and undergo a type of sexual reproduction. The amastigotes multiply until they block the sandfly pharynx. The amastigotes transform into infective metacyclic promastigotes that invade through the gut wall and move to the salivary glands from which they are ingested the next time the sandfly feeds. The amastigotes transform into the procyclic promastigote stage.

Explanation / Answer

E) AMASTIOGOTES TRANSFORM INTO THE PROCYCLIC PROMASTIGOTE STAGE
