The endemicity of cutaneous leishmaniasis (CL) caused by Leishmania tropica was ascertained in a focus of the disease around Eira and Yarqa in Salt District, Jordan. This focus is about 10 km to the east of another focus of CL, where L. major is the causative agent. As CL occurs sporadically in the study area, with nine cases diagnosed between 1993 and 1995, it is probably zoonotic. Each case had one or two lesions and most lesions were on the face. Isoenzymatic electrophoresis showed that all the parasites isolated in the Eira-Yarqa focus and identified to zymodeme level belonged to zymodeme MON-137 and therefore differed from all the L. tropica isolates identified in other regions of Jordan. Eight species of Phlebotomus (P. alexandri, P. major, P. sergenti, P. papatasi, P. perfiliewi, P. jacusieli, P. canaaniticus and P. arabicus), two members of the Sergentomyia dentata group and S. tiberiadis and S. taizi were collected in the focus, using castor-oil traps. The epidemiological significance of the sandflies collected is discussed.
在约旦盐区埃拉和亚尔卡周围的皮肤利什曼病疫源地，确定了热带利什曼原虫引起的皮肤利什曼病（CL）的地方性。该疫源地位于另一个以硕大利什曼原虫为病原体的CL疫源地以东约10公里处。由于CL在研究区域呈散发性发生，1993年至1995年间诊断出9例病例，所以该病可能为人畜共患病。每例病例有一两个皮损，大多数皮损位于面部。同工酶电泳显示，在埃拉 - 亚尔卡疫源地分离并鉴定到酶带型水平的所有寄生虫均属于酶带型MON - 137，因此与在约旦其他地区鉴定的所有热带利什曼原虫分离株不同。使用蓖麻油诱捕器在该疫源地采集到了8种白蛉（亚历山大白蛉、大劣白蛉、塞尔吉白蛉、巴氏白蛉、佩氏白蛉、雅库氏白蛉、迦南白蛉和阿拉伯白蛉）、2种齿蛉属的成员以及台伯齿蛉和太子齿蛉。文中讨论了所采集白蛉的流行病学意义。
