Cystic echinococcosis is one of the most widespread and important helminthic zoonoses, caused by the larval stage of Echinococcus granulosus sensu lato. However, to date there is little information about the disease in West Africa. Faecal and fur samples from 193 dogs, the main final hosts, were collected in 2010 and 2011 in Bamako, Mali. Taeniid eggs were found microscopically in 28/118 (24%) and 80/223 (36%) faecal and fur samples, respectively. One faecal and one fur sample from the same dog were positive for E. granulosus s. l. DNA. In the remaining 27 faecal (96%) and 77 fur samples (96%) only Taenia DNA was detected. Three microscopically positive fur samples were negative by PCR. Sequence analysis of part of the NADH dehydrogenase subunit 1 gene identified the parasite as E. granulosus (genotype G6; Echinococcus canadensis). This is the first study to focus on the final host of E. granulosus s. l. in Mali and the first report of E. canadensis in Mali.
囊性棘球蚴病是最广泛且重要的蠕虫性人畜共患病之一，由细粒棘球绦虫复合种的幼虫阶段引起。然而，迄今为止，关于西非该疾病的信息很少。2010年和2011年在马里巴马科采集了193只主要终末宿主狗的粪便和毛发样本。在粪便和毛发样本中，分别在28/118（24%）和80/223（36%）中显微镜下发现带绦虫卵。来自同一只狗的一份粪便样本和一份毛发样本细粒棘球绦虫复合种DNA呈阳性。在其余27份粪便样本（96%）和77份毛发样本（96%）中仅检测到绦虫DNA。三份显微镜下呈阳性的毛发样本经PCR检测为阴性。对烟酰胺腺嘌呤二核苷酸脱氢酶亚基1基因部分序列的分析确定该寄生虫为细粒棘球绦虫（基因型G6；加拿大棘球绦虫）。这是第一项聚焦于马里细粒棘球绦虫复合种终末宿主的研究，也是马里关于加拿大棘球绦虫的首次报告。
