Zoonotic cutaneous leishmaniasis (ZCL) is a form of disease, which is mostly caused by ) in the Old World with high incidence through early life. Recently, the high incidence of CL has been reported in Jajarm County, northeastern Iran. The aim of the present study was to investigate the epidemiological aspects of CL and to identify spp. in the area. Between 2012 and 2018, patients with active lesions suspected of CL were examined. Diagnosis was performed by methods of clinical examination and direct smears. Conventional kDNA polymerase chain reaction (PCR) was used to identify species of . During the seven-year study period, 629 subjects were diagnosed as CL cases by clinical and microscopic examination. Considering the population of the study area, the average incidence rate was 237.8 per 100,000 population. Most (29.4%) of the subjects with ZCL were aged <10 years. Most of the patients (58.7%) were male and the rest were female. Most ulcers were observed on the face (32.2%) and hands (23.7%), respectively. Most patients (90%) had two or more ulcers on their body. The highest incidence was in the autumn in October (32%). Our data revealed that an ongoing reemergence of ZCL focus caused by has arisen in the study area. Moreover, direct PCR on the smears for identifying showed 100% specificity, and the species was identified as using species -specific kDNA PCR. The use of conventional PCR on skin smears seems to provide a valuable method for confirming the clinical diagnosis of ZCL, which is very specific and sensitive particularly for clinical correlative studies. Further investigations are needed to improve planning strategies of vectors and reservoirs populations.
人兽共患皮肤利什曼病(ZCL)是一种疾病形式,在旧世界主要由[某种病原体]引起,在早年发病率很高。最近,伊朗东北部贾尔姆县报告了利什曼病的高发病率。本研究的目的是调查该地区利什曼病的流行病学特征并鉴定[病原体种类]。在2012年至2018年期间,对疑似患有活动性利什曼病病变的患者进行了检查。通过临床检查和直接涂片方法进行诊断。使用传统的kDNA聚合酶链反应(PCR)来鉴定[病原体种类]。在为期七年的研究期间,629名受试者通过临床和显微镜检查被诊断为利什曼病病例。考虑到研究区域的人口,平均发病率为每10万人237.8例。大多数(29.4%)ZCL受试者年龄小于10岁。大多数患者(58.7%)为男性,其余为女性。大多数溃疡分别出现在面部(32.2%)和手部(23.7%)。大多数患者(90%)身上有两个或更多溃疡。发病率最高的是10月秋季(32%)。我们的数据显示,研究区域出现了由[病原体]引起的ZCL病灶的持续再现。此外,对涂片进行直接PCR以鉴定[病原体]显示特异性为100%,并且使用种特异性kDNA PCR将该物种鉴定为[具体物种]。在皮肤涂片上使用传统PCR似乎为确认ZCL的临床诊断提供了一种有价值的方法,该方法非常特异且敏感,尤其适用于临床相关研究。需要进一步调查以改进病媒和宿主种群的规划策略。
