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.
关于血液原生动物感染如何改变爬行动物血液学的知识知之甚少。蜥蜴 Ameiva ameiva 广泛分布于美洲,并且感染血液原生动物寄生虫。此前对这种蜥蜴的研究表明,感染宿主细胞的单核细胞寄生虫会引起各种超微结构变化。本研究报告称,这种感染不会导致红细胞值发生任何变化。但是,检测到白细胞(尤其是单核细胞)数量明显增加。这表明血孢子虫不仅调节感染的单核细胞,而且还增加了这种白细胞的血液池。还发现有一种疟原虫感染了一只蜥蜴的红细胞。
