Of blood films examined from 170 specimens of 15 Chamaeleo spp. in Tanzania, three C. dilepis had an intracytoplasmic inclusion within monocytes. One of the lizards was maintained in captivity and was sequentially bled over a 55 day period. At 46 days, a second type of inclusion was occasionally seen within monocytes. The lizard became ill and was euthanatized on day 55. All circulating monocytes were found to have either one or both types of inclusions. Histologic examination of multiple tissues demonstrated similar inclusions within macrophages in the spleen and liver. Transmission electron microscopic examination of monocytes revealed the presence of a chlamydia-like organism and pox-like virus. These pathogens have not been reported previously in chameleons, nor has a combined infection of circulating monocytes with these two pathogens been reported for any animal.
在对坦桑尼亚15种避役属物种的170个样本进行的血涂片检查中，3只双角避役的单核细胞内有胞质内包涵体。其中一只蜥蜴被圈养，并在55天内连续采血。在第46天，偶尔在单核细胞内发现第二种类型的包涵体。这只蜥蜴生病并在第55天被安乐死。发现所有循环单核细胞都有其中一种或两种类型的包涵体。对多个组织的组织学检查显示，脾脏和肝脏中的巨噬细胞内有类似的包涵体。对单核细胞的透射电子显微镜检查显示存在一种衣原体样生物和痘样病毒。这些病原体以前在变色龙中未见报道，也没有任何动物的循环单核细胞被这两种病原体联合感染的报道。
