Hematological parameters of Ameiva ameiva (Reptilia: Teiidae) naturally infected with hemogregarine: confirmation of monocytosis.
Little is known on how hematozoan infection changes reptile hematology. The lizard Ameiva ameiva is widely distributed in the Americas and is infected by hematozoan parasites. Previous studies on this lizard have shown that the parasite of monocytes causes a variety of ultrastructural changes in infected host cells. The present study reports that this infection does not cause any change to the erythrocytic values. However, a marked increase in the number of leukocytes (especially monocytes) was detected. This indicates that the hemogregarine not only modulates the infected monocyte, but also increases the blood pool of this leukocyte. A Plasmodium sp was also found infecting erythrocytes of one lizard.
