Filariae are common parasites of dogs in many parts of the world, but little is known about the status of these infections in sub-Saharan Africa. A study was carried out to determine the occurrence and species of filariae among 272 dogs in Lusaka, Zambia. Giemsa stained blood smear and Knott's concentration methods revealed microfilariae in 16 (5.9%) of the dogs. PCR confirmed that most of these dogs had Acanthocheilonema reconditum infection. Ten (4.0%) of the examined dogs were positive for Dirofilaria immitis circulating antigen (by DiroCHEK(®) test), but D. immitis microfilariae were not identified in any of the dogs and the status of this infection remains unclear. Further studies are needed to explore the occurrence of filariae in Zambian dogs and the zoonotic potential for humans.
丝虫是世界上许多地区犬类常见的寄生虫，但对于撒哈拉以南非洲地区这些感染的状况了解甚少。开展了一项研究，以确定赞比亚卢萨卡272只犬中丝虫的感染情况及种类。吉姆萨染色血涂片和诺特浓集法在16只（5.9%）犬中发现了微丝蚴。聚合酶链反应证实，这些犬中的大多数感染了隐匿棘唇线虫。10只（4.0%）受检犬的犬恶丝虫循环抗原检测呈阳性（通过DiroCHEK®检测），但在任何一只犬中均未发现犬恶丝虫微丝蚴，这种感染的状况仍不清楚。需要进一步研究以探索赞比亚犬中丝虫的感染情况以及对人类的人畜共患病潜力。
