Mature and immature stages of Haemoproteus columbae gametocytes, an avian haemosporidian protozoan parasite were found in 75% of blood smears prepared from 30 healthy domestic pigeons in Sebele location, Gaborone, Botswana. Parenteral administration of an immuno-suppressive dose of dexamethasone, lowered the level of parasitaemia, the packed cell volume and the heterophil:lymphocyte ratio in the test pigeons. However, both the dexamethasone-treated and the control pigeons remained clinically normal.
在博茨瓦纳哈博罗内塞贝莱地区采集的30只健康家鸽制备的血涂片样本中，75%的样本发现了鸽血变原虫（一种鸟类血孢子虫原生动物寄生虫）配子体的成熟和未成熟阶段。对实验鸽进行免疫抑制剂量的地塞米松肠胃外给药后，其寄生虫血症水平、红细胞压积和嗜异性粒细胞与淋巴细胞比例均有所降低。然而，地塞米松处理组和对照组鸽子在临床上均保持正常。
