Ticks are important vectors of emerging health problems in humans and animals. We conducted several field surveillances to investigate the fauna of hard ticks on domestic animals in seven governorates of Egypt during 2018-2019. A total of 3265 individual tick specimens were collected and identified to the species level; the specimens belong to 11 species within three genera (Amblyomma, Hyalomma, and Rhipicephalus). Tick infestation was highest in dromedary camels (70%), followed by dogs (52.5%), cattle (50%), buffaloes (38%), and horses (12%). Ten species were collected from dromedary camels, 2 from cattle, and one species from dogs, buffaloes, and horses. Diagnostic characters with high-quality photographic images of the 11 tick species were provided. New measurements of the body regions such as spiracles and body grooves were also obtained to provide further details on morphological variations among the diverse tick species. This study provided detailed descriptions of the genital apertures of five Hyalomma species. Morphological variations of male Hyalomma impeltatum, and genital apertures of female Hyalomma dromedarii and Hyalomma excavatum were also examined in this study. Finally, we provided additional details on local geographic distributions, hosts, endemicity status, and disease relationships of the eleven tick species.
蜱虫是人类和动物新兴健康问题的重要传播媒介。我们在 2018 年至 2019 年期间在埃及的七个省进行了几次实地调查，以调查家畜硬蜱的动物群。共采集并鉴定了 3265 个个体蜱标本；这些标本属于三个属（硬蜱属、璃眼蜱属和血蜱属）的 11 个种。在单峰骆驼（70%）中，蜱虫的感染率最高，其次是狗（52.5%）、牛（50%）、水牛（38%）和马（12%）。从单峰骆驼中采集到 10 种，从牛中采集到 2 种，从狗、水牛和马中采集到 1 种。提供了 11 种蜱虫的具有高质量照片的诊断特征。还获得了体腔和体沟等身体部位的新测量值，以提供有关不同蜱种之间形态变异的更多详细信息。本研究详细描述了 5 种璃眼蜱属的生殖器开口。本研究还检查了雄性硬蜱的形态变异，以及雌性单峰驼血蜱和荒地血蜱的生殖器开口。最后，我们提供了关于 11 种蜱虫的本地地理分布、宿主、特有性状况和疾病关系的更多详细信息。
