Abstract：
Strongyloides stercoralis is a zoonotic parasite, infecting human, cats and dogs. The infection is typical of tropical and subtropical areas, while it is underestimated in temperate countries. In Europe, data from humans demonstrate a large variability of infection prevalence; while scarce literature is available for dogs, with most cases reported in kennel dogs from southern Italy. A privately owned 8-month-old French Bulldog was examined because of chronic cough, diarrhea, and poor body conditions. Radiography of the thorax revealed a diffuse bronchial pattern and abdominal ultrasound showed unspecific signs of inflammation. Cytological analysis of a rectal swab revealed the presence of larvae compatible with Strongyloides sp. A parasitic infection causing protein-losing enteropathy and bronchopneumonia was suspected and fenbendazole was administered with a poor clinical response. Fecal Baermann test revealed S. stercoralis rhabditiform larvae and thinshelled eggs. Clinical signs resolved progressively after two subcutaneous ivermectin administrations (off-label) given two weeks apart. Serial coprological controls scheduled in the following 6 months were negative for larvae and eggs. Fecal real-time PCR confirmed negative results 6 months after treatment. The authors describe for the first time a case of S. stercoralis infection in a privately-owned dog from north-west of Italy (Piedmont).
摘要：
类圆圆线虫是一种人畜共患寄生虫，感染人类，猫和狗。感染是典型的热带和亚热带地区，虽然在温带国家被低估了。在欧洲,来自人类的数据表明感染患病率有很大的变异性；虽然狗的文献很少，据报道，大多数病例发生在意大利南部的狗窝犬中。一名私人拥有的8个月大的法国斗牛犬因慢性咳嗽而接受了检查，腹泻,和恶劣的身体状况。胸部X线照相术显示弥漫性支气管模式，腹部超声显示炎症的非特异性迹象。直肠拭子的细胞学分析显示，存在与Strongyloidessp兼容的幼虫。怀疑是寄生虫感染导致蛋白质丢失性肠病和支气管肺炎，并且芬苯达唑的临床反应较差。粪便Baermann试验显示胸骨横纹肌状幼虫和薄壳卵。间隔两周两次皮下伊维菌素给药（标签外）后，临床体征逐渐消失。在接下来的6个月中计划的连续共产对照对幼虫和卵呈阴性。粪便实时PCR在治疗后6个月证实阴性结果。作者首次描述了来自意大利西北部（皮埃蒙特）的私人犬中的S.stercoralis感染病例。
