This protozoan is a digenetic as its life-cycle is passed in two hosts. The primary host is man and the secondary host is the sand fly (Phlebotomus sp). There are three very closely

The rapid swimming is facilitated by the beating of fine and hair-like cellular organelles, called cilia, that cover the animal’s entire cell-body. Paramoecium moves with
