use protozoon in a sentence.
The malarial haematozoon is a protozoon, a very small protozoon since it lives and develops in the red blood cells which in man have a diameter of only 7 microns.
It is spread from person to person by the bite of the tsetse fly, which carries the protozoon and is famous for that reason.
Let us begin our comparative study with an example of the simplest animals that consist of only a single cell, such as the little protozoon
Usually the sexual forms develop only in a special environment; thus the protozoon which in man is the cause of malaria, multiplies in the human blood by simple division, but in the body of the mosquito multiplication by sexual differentiation takes place.
Organic life, we are told, has developed gradually from the protozoon to the philosopher, and this development, we are assured, is indubitably an advance.
