Abstract

Phleboviruses are common human pathogens diffused on the Mediterranean area whose infection can cause the typical prodromal symptom of a mild three‑days fever. In particular, Toscana Virus (TOSV) has a great concern since its capacity to provoke central nervous system disorders like meningoencephalitis. Furthermore, as the phlebotomine arthropod vectors represent the main carrier for pathogens of the genus Leishmania as well, the purpose of the study was to investigate the presence of TOSV in Lampedusa, Italy previously reported for leishmaniosis infection cases. The survey was carried out through an initial sampling phase of sand flies, by means of CDC light traps, and a second step of molecular analyses. The genomic S‑segment of TOSV was targeted. The positive samples were sequenced and compared with those available in GenBank™ using Basic Local Alignments Tool (BLAST) analyses. The study revealed for the first time the presence of TOSV in Lampedusa, Italy. The entomological studies directed on vectors are currently widely used in sand fly surveillance, and new data on TOSV are of public health concern.

在兰佩杜萨岛（意大利）的嗜血沙蝇身上检测到嗜血病毒。

嗜血病毒是散布在地中海地区的常见人类病原体，其感染可引起典型的前驱症状，即轻度发烧三天。尤其是托斯卡纳病毒（TOSV），由于其能够引发脑膜脑炎等中枢神经系统疾病，因此备受关注。此外，由于噬线虫类节肢动物载体也是利什曼病属病原体的主要载体，因此本研究的目的是调查意大利兰佩杜萨是否存在之前报告的利什曼病感染病例中的托斯卡纳病毒。调查的第一步是通过疾控中心的灯光诱捕器对沙蝇进行采样，第二步是进行分子分析。目标是 TOSV 的基因组 S 片段。对阳性样本进行了测序，并使用基本局部比对工具（BLAST）与 GenBank™ 中的样本进行了比对。研究首次发现意大利兰佩杜萨存在 TOSV。针对病媒的昆虫学研究目前被广泛用于沙蝇监测，而关于 TOSV 的新数据则关系到公共卫生问题。

期刊介绍： The journal was created as the Croce Azzurra in 1950. A quarterly peer-reviewed journal devoted to veterinary public health and other aspects of veterinary science and medicine, Veterinaria Italiana is published by the Istituto Zooprofilattico Sperimentale dell’Abruzzo e del Molise ‘G. Caporale’ (Istituto Zooprofilattico Sperimentale dell''Abruzzo e del Molise) in Teramo, Italy. The goal of the journal is to provide an international platform for veterinary public health information from Italy and other countries, particularly those in Eastern Europe and Africa, Asia and South America. Veterinarians and veterinary public health specialists are encouraged to share their knowledge and experience on this platform.
