BACKGROUND
Zoonotic cutaneous leishmaniasis (ZCL) is widely distributed in Iran and around the world. Also, Khuzestan Province is an endemic focus of ZCL. This study aims to investigate the natural infection of sand flies with the parasite in Karun County.
METHODS
Sand flies were collected from Jangiyeh, Qaleh Chanan, Kut-e-Navaser, and Ghazavieh in the spring and summer in the year of 2019, by installing 60 sticky paper traps each time (30 traps outdoors and 30 traps indoors). Two hundred female sand flies with different abdominal conditions (empty, blood-fed, semi-gravid, and gravid) were examined for infection rate using the Nested-PCR method.
RESULTS
In this study, seven species of sand flies including , , , , , , and were reported from Karun County, with a frequency of 79.64%, 16.96%, 1.07%, 0.18%, 0.36%, 1.61%, and 0.18%, respectively. Only eleven specimens of were found to be positive for , with an overall infection rate of 7.8%. The infection of was specifically reported in blood-fed, gravid, and semi-gravid specimens, with infection rates of 17.02%, 4.35%, and 14.29%, respectively.
CONCLUSION
In this study, the infection of from was reported. The results can be used in planning the control of ZCL in the study area.
背景
人兽共患皮肤利什曼病（ZCL）在伊朗及世界各地广泛分布。此外，胡齐斯坦省是ZCL的一个地方性疫源地。本研究旨在调查卡伦县白蛉体内该寄生虫的自然感染情况。
方法
2019年春夏两季，通过每次设置60个粘纸诱捕器（30个室外诱捕器和30个室内诱捕器），从詹吉耶、卡莱查南、库特 - 纳瓦塞尔和加扎维耶采集白蛉。使用巢式聚合酶链反应（Nested-PCR）方法检查200只腹部状况不同（空腹、吸血、半妊娠和妊娠）的雌性白蛉的感染率。
结果
在本研究中，从卡伦县报告了7种白蛉，分别为[具体种类1]、[具体种类2]、[具体种类3]、[具体种类4]、[具体种类5]、[具体种类6]和[具体种类7]，频率分别为79.64%、16.96%、1.07%、0.18%、0.36%、1.61%和0.18%。仅发现11只[具体种类]的标本对[寄生虫名称]呈阳性，总体感染率为7.8%。[寄生虫名称]的感染在吸血、妊娠和半妊娠标本中被特别报告，感染率分别为17.02%、4.35%和14.29%。
结论
在本研究中，报告了来自[具体种类]的[寄生虫名称]感染情况。该结果可用于规划研究区域内ZCL的控制工作。
