Abstract

This study was conducted to clarify the host specificity and the geographical distribution of Gasterophilus species (Diptera, Oestridae) in the Serengeti ecosystem. A total of 317 larvae were recovered from two common zebras (Equus quagga, formerly Equus burchellii) in Maswa Game Reserve, and 58 larvae were recovered from an African lion (Panthera leo) in the Serengeti National Park. The study emphasizes the rare occurrence of Gasterophilus sp. in lions, shedding light on the broader life cycle and physiological implications for hosts. Genetic analysis of cox2 genes from Gasterophilus species, sourced from a single geographic location, reveals significant genetic distinctions and host specificity. This study reports the first case of G. intestinalis infestation in an African lion in the Serengeti ecosystem, extending its known range from zebras and other equids, and highlighting ecological and veterinary implications. This unusual prey-predator transmission highlights the value of molecular taxonomic tools in clarifying host-parasite dynamics and guiding targeted conservation strategies.

塞伦盖蒂生态系统中狮子（Panthera leo）和平原斑马（Equus quagga）的肠道Gasterophilus虫害：形态学和分子分析。

本研究旨在阐明塞伦盖蒂生态系统中 Gasterophilus 种（双翅目，Oestridae）的寄主特异性和地理分布。研究人员从马斯瓦野生动物保护区的两只普通斑马（Equus quagga，原名Equus burchellii）身上发现了317只幼虫，并从塞伦盖蒂国家公园的一只非洲狮（Panthera leo）身上发现了58只幼虫。该研究强调了狮体内 Gasterophilus sp.的罕见性，揭示了其更广泛的生命周期和对宿主的生理影响。对来自单一地理位置的Gasterophilus物种的cox2基因进行遗传分析，发现了显著的遗传差异和宿主特异性。本研究报告了塞伦盖蒂生态系统中第一例非洲狮肠道鹅膏菌感染病例，扩大了斑马和其他马科动物的已知感染范围，并强调了其对生态学和兽医学的影响。这种不寻常的猎物-食肉动物传播凸显了分子分类工具在阐明宿主-寄生虫动态和指导有针对性的保护策略方面的价值。

期刊介绍： Parasite is an international open-access, peer-reviewed, online journal publishing high quality papers on all aspects of human and animal parasitology. Reviews, articles and short notes may be submitted. Fields include, but are not limited to: general, medical and veterinary parasitology; morphology, including ultrastructure; parasite systematics, including entomology, acarology, helminthology and protistology, and molecular analyses; molecular biology and biochemistry; immunology of parasitic diseases; host-parasite relationships; ecology and life history of parasites; epidemiology; therapeutics; new diagnostic tools. All papers in Parasite are published in English. Manuscripts should have a broad interest and must not have been published or submitted elsewhere. No limit is imposed on the length of manuscripts, but they should be concisely written. Papers of limited interest such as case reports, epidemiological studies in punctual areas, isolated new geographical records, and systematic descriptions of single species will generally not be accepted, but might be considered if the authors succeed in demonstrating their interest.
