The presence of Dirofilaria repens has been mentioned in Europe, in Africa and in Asia, in different carnivores (dogs, foxes, cats, lions). In Europe the nematode has been reported in dogs, cats and foxes and the countries concerned by native cases are Italy, Spain, Greece, Yugoslavia and France. In France, until now, D. repens has been described, among animals, only in dogs. The first undoubted report dates back to 1953. Later, the prevalence was studied through widespread surveys (1986-1988-1989), focal surveys within some canine populations (military dogs) and some sporadic and fortuitous descriptions. The prevalence has been mainly assessed by pointing up the microfilariae in the blood and by identifying it after histochemical staining (for demonstration of the somatic distribution of acid phosphatase activity). The infestation rate was higher than 20% in some military dog populations. The cases occurred in nineteen French departments (Alpes-de-Haute-Provence, Aude, Bouches-du-Rhône, Corrèze, Corse, Dordogne, Gard, Gers, Gironde, Haute-Garonne, Loir-et-Cher, Nièvre, Pyrénées-Orientales, Rhône, Tarnet-Garonne, Var, Vaucluse, Vienne and Region Parisienne). The pathogenicity which is normally denied has to be reconsidered. The pathology of adult worms has not been clearly proved in dogs but the embolized microfilariae can bring about skin troubles. The potential pathogenicity, the necessity of the differentiation with D. immitis and above all, the zoonotic importance of D. repens must lead to search for it more often and to consider it with great interest.
匐行恶丝虫已在欧洲、非洲和亚洲的不同食肉动物(狗、狐狸、猫、狮子)体内被发现。在欧洲,线虫已在狗、猫和狐狸体内被报道,出现本地病例的国家有意大利、西班牙、希腊、南斯拉夫和法国。在法国,到目前为止,匐行恶丝虫仅在狗等动物体内有记载。首次确凿的报告可追溯到1953年。后来,通过广泛调查(1986 - 1988 - 1989年)、对一些犬类群体(军犬)进行的重点调查以及一些零星和偶然的描述对其流行情况进行了研究。流行率主要通过检测血液中的微丝蚴并在组织化学染色后进行鉴定(以显示酸性磷酸酶活性的体细胞分布)来评估。在一些军犬群体中,感染率高于20%。病例发生在法国的19个省(上普罗旺斯阿尔卑斯省、奥德省、罗讷河口省、科雷兹省、科西嘉岛、多尔多涅省、加尔省、热尔省、吉伦特省、上加龙省、卢瓦雷省、涅夫勒省、东比利牛斯省、罗讷省、塔恩 - 加龙省、瓦尔省、沃克吕兹省、维埃纳省和巴黎地区)。通常被否认的致病性必须重新审视。狗体内成虫的病理学尚未得到明确证实,但栓塞的微丝蚴可引发皮肤问题。匐行恶丝虫的潜在致病性、与犬恶丝虫进行区分的必要性,尤其是其对人畜共患病的重要性,必须促使人们更频繁地对其进行检测并给予高度关注。
