Abstract

Leishmania tarentolae and Leishmania infantum are two sympatric parasites of significant ecological and epidemiological interest in the Mediterranean basin. This study investigated the PCR prevalence of L. tarentolae and L. infantum in two gecko species (Tarentola mauritanica and Hemidactylus turcicus) present on Mallorca Island, Spain, using duplex quantitative PCR. A total of 59 geckos were sampled across the island, including 53 T. mauritanica and six H. turcicus. Tissue and blood samples were screened by PCR for both parasites. The results revealed the prevalence of Leishmania infection in adult T. mauritanica, with 10/49 (20.41 %) testing PCR positive for L. tarentolae only and with 1/49 (2.04 %) for L. infantum only. Coinfection with both parasites was detected in 3/49 geckos (6.12 %). No positives were identified in H. turcicus, probably due to small sample size. Regarding PCR positivity by tissues, coleomic organs were more likely to be positive for L. tarentolae in adult T. mauritanica than blood, with a slighter PCR positivity in the liver, spleen and lung. This study provides further insight into the interaction between Leishmania and geckos in leishmaniosis-endemic areas such as Mallorca.

西班牙马略卡岛壁虎的小利什曼原虫和小利什曼原虫
绦虫利什曼原虫和幼利什曼原虫是地中海盆地具有重要生态和流行病学意义的两种同域寄生虫。本研究采用双工定量PCR方法,对西班牙马略卡岛两种壁虎(毛利塔尼壁虎和半爪壁虎)中Tarentola和婴儿乳杆菌的PCR流行率进行了研究。全岛共采集壁虎59只,其中毛利塔尼察壁虎53只,土壁虎6只。用PCR方法对两种寄生虫的组织和血液样本进行筛选。结果显示,毛里塔尼亚成年弓形虫感染利什曼原虫的比例为10/49(20.41%),仅为tarentolae,仅为婴儿弓形虫为1/49(2.04%)。3/49的壁虎同时感染两种寄生虫(6.12%)。可能是由于样本量小,未在黄芽孢杆菌中发现阳性。在组织PCR阳性方面,毛利塔尼察成虫结肠组器官比血液更容易检测到链状乳杆菌,肝脏、脾脏和肺部的PCR阳性程度较轻。这项研究为利什曼原虫和壁虎在马略卡岛等利什曼原虫流行地区的相互作用提供了进一步的见解。

期刊介绍: The International Journal for Parasitology: Parasites and Wildlife (IJP-PAW) publishes the results of original research on parasites of all wildlife, invertebrate and vertebrate. This includes free-ranging, wild populations, as well as captive wildlife, semi-domesticated species (e.g. reindeer) and farmed populations of recently domesticated or wild-captured species (e.g. cultured fishes). Articles on all aspects of wildlife parasitology are welcomed including taxonomy, biodiversity and distribution, ecology and epidemiology, population biology and host-parasite relationships. The impact of parasites on the health and conservation of wildlife is seen as an important area covered by the journal especially the potential role of environmental factors, for example climate. Also important to the journal is ''one health'' and the nature of interactions between wildlife, people and domestic animals, including disease emergence and zoonoses.
