Leishmania infantum is the principal agent of visceral leishmaniosis (kala-azar) in all areas of Iran. The disease is endemic in Fars, Ardabil, East Azerbaijan and Bushehr provinces while it is sporadic in other parts of the country. Dog as a member of canidae family is the main animal reservoir host of kala-azar. The present study was carried out to determine the sero-prevalence of canine leishmaniosis in Mashhad, the capital city of Khorasan Razavi Province, in the north east of Iran. Two-hundred and nine dogs in two different classes including stray and sheepdogs were selected for this cross-sectional study. The blood samples were collected and tested by indirect immunofluorescent antibody test for detection of anti-Leishmania infantum antibodies. The results showed that 16/209 (7.6 %) of blood samples were positive. The sero-prevalence rates in stray and sheepdogs were 11/94 (11.7 %) and 5/115 (4.3 %), respectively (p < 0.05). Based on the results obtained, it is concluded that visceral leishmaniosis is distributed among dogs of this area, also sero-prevalence of canine leishmaniosis in stray dogs higher than sheepdogs.
婴儿利什曼原虫是伊朗所有地区内脏利什曼病（黑热病）的主要病原体。该病在法尔斯省、阿尔达比勒省、东阿塞拜疆省和布什尔省呈地方性流行，而在该国其他地区为散发性。犬作为犬科动物的一员，是黑热病的主要动物储存宿主。本研究旨在确定伊朗东北部霍拉桑拉扎维省省会马什哈德犬类利什曼病的血清流行率。本横断面研究选取了包括流浪犬和牧羊犬在内的两个不同类别的209只犬。采集血样并通过间接免疫荧光抗体试验检测抗婴儿利什曼原虫抗体。结果显示，209份血样中有16份（7.6%）呈阳性。流浪犬和牧羊犬的血清流行率分别为11/94（11.7%）和5/115（4.3%）（p<0.05）。根据所得结果得出结论，内脏利什曼病在该地区的犬中存在分布，且流浪犬的犬类利什曼病血清流行率高于牧羊犬。
