A seroprevalence study of canine leishmaniasis was carried out in five provinces in northern Morocco: Taounate, Al Hoceima, Zouagha Moulay Yacoub, Chefchaouen and Ouezzane. 55 localities have been concerned and a total of 1,013 dogs were screened, which represents almost 100% of the canine census. Of the screened dogs: 87 showed antibody titer > or = 100 when tested by IFAT (seroprevalence of 8.6%) and were distributed in 83 asymptomatics (without clinical symptoms) and four symptomatics (with one or several symptoms of leishmaniasis) with important variations according to the locality. Relative frequency of asymptomatic dogs was observed (8.2%), and the seroprevalence increased in middle altitude (500 m < altitude < 1,000 m) and high altitude (> or = 1,000 m). Parasites isolated from dogs were identified as L. infantum MON-1 by isoenzyme profile and Rsal digestion.
在摩洛哥北部的五个省份开展了一项犬利什曼病血清阳性率研究，这五个省份分别是陶纳特、胡塞马、穆莱·亚库布苏阿加、舍夫沙万和乌埃德赞。共有55个地区参与其中，总共筛查了1013只狗，这几乎占犬类普查数量的100%。在接受筛查的狗中：通过间接荧光抗体试验（IFAT）检测时，87只狗的抗体滴度≥100（血清阳性率为8.6%），这些狗分布在83只无症状（无临床症状）和4只有症状（有一项或多项利什曼病症状）的狗中，且根据地区不同存在显著差异。观察到无症状狗的相对频率为（8.2%），血清阳性率在中等海拔（500米＜海拔＜1000米）和高海拔（≥1000米）地区有所增加。通过同工酶谱和Rsal消化法，从狗身上分离出的寄生虫被鉴定为婴儿利什曼原虫MON-Ⅰ型。
