Nematode larvae found in histological cuts of lung tissue of a horse from a farm in Al Dhaid (UAE) were determined to belong to the Habronematidae family. The clinical examination of the other 18 horses present in the farm revealed summer sores (cutaneous habronemosis) in two stallions. Nematode larvae were found in 147 (=26.2%) out of 561 male but only in 64 (=8.7%) out of 739 female Musca domestica caught at the farm in November and December 2008. Conversely, all 15 Stomoxys calcitrans specimens caught in the farm resulted negative for nematode larvae. The housefly population caught in the barn showed a prevalence of 20.9% with nematode larvae, while flies trapped outside the building on the territory of the farm had a much lower prevalence of 1.1%. The intensity of infection varied between one and 29 larvae per head. Larvae retrieved at the fly dissection were subjected to a ribosomal DNA-targeting semi-nested PCR protocol able to discriminate among the three nematode species Habronema muscae, Habronema microstoma, and Draschia megastoma. The larvae were identified to be H. muscae.
从阿联酋阿尔达哈伊（Al Dhaid）的一个农场的马的肺组织的组织学切片中发现的线虫幼虫被确定属于旋毛线虫科。对农场中其余 18 匹马的临床检查发现，两匹种马患有夏季疮（皮肤旋毛虫病）。2008 年 11 月和 12 月在该农场捕获的 561 只雄性家蝇中有 147 只（26.2%）发现了线虫幼虫，而在 739 只雌性家蝇中仅发现 64 只（8.7%）。相反，在农场捕获的所有 15 只厩螫蝇标本均未发现线虫幼虫。在谷仓中捕获的家蝇种群的感染率为 20.9%，带有线虫幼虫，而在农场区域建筑物外捕获的苍蝇的感染率要低得多，为 1.1%。感染强度在每头 1 到 29 条幼虫之间不等。在蝇解剖中检索到的幼虫经过核糖体 DNA 靶向半巢式 PCR 方案进行鉴定，该方案能够区分三种线虫物种，即马胃蝇、微小胃蝇和大胃蝇。幼虫被鉴定为马胃蝇。
