Abstract

Tsetse flies are well-known vectors of trypanosomes pathogenic for humans and livestock. For these strictly blood-feeding viviparous flies, the host blood should be the only source of nutrients and liquids, as well as any exogenous microorganisms colonising their intestine. Here we describe the unexpected finding of several monoxenous trypanosomatids in their gut. In a total of 564 individually examined Glossina (Austenia) tabaniformis (Westwood) (436 specimens) and Glossina (Nemorhina) fuscipes fuscipes (Newstead) (128 specimens) captured in the Dzanga-Sangha Protected Areas, Central African Republic, 24 (4.3%) individuals were infected with monoxenous trypanosomatids belonging to the genera Crithidia Léger, 1902; Kentomonas Votýpka, Yurchenko, Kostygov et Lukeš, 2014; Novymonas Kostygov et Yurchenko, 2020; Obscuromonas Votýpka et Lukeš, 2021; and Wallacemonas Kostygov et Yurchenko, 2014. Moreover, additional 20 (3.5%) inspected tsetse flies harboured free-living bodonids affiliated with the genera Dimastigella Sandon, 1928; Neobodo Vickerman, 2004; Parabodo Skuja, 1939; and Rhynchomonas Klebs, 1892. In the context of the recently described feeding behaviour of these dipterans, we propose that they become infected while taking sugar meals and water, providing indirect evidence that blood is not their only source of food and liquids.

单毒锥虫如何揭示其采采蝇宿主隐藏的摄食习性。

采采蝇是众所周知的对人类和牲畜致病的锥虫病媒介。对于这些严格以血液为食的胎生苍蝇来说，宿主的血液应该是营养物质和液体的唯一来源，以及任何在它们肠道内定植的外源微生物。在这里，我们描述了在他们的肠道中意外发现的几种单源锥虫。在中非共和国Dzanga-Sangha保护区捕获的564只单独检查的tabaniformis (Austenia) (Westwood)(436只标本)和fuscipes (Nemorhina) (Newstead)(128只标本)中，有24只(4.3%)感染了属于Crithidia lsamger属的单毒锥虫虫，1902年;Kentomonas Votýpka, Yurchenko, Kostygov et lukesi, 2014;Novymonas Kostygov et Yurchenko, 2020;隐球菌Votýpka et lukesi, 2021;Wallacemonas Kostygov et Yurchenko, 2014。此外，另外20只(3.5%)被检采采蝇携带了Dimastigella Sandon(1928)属的自由生活的骨齿动物;Neobodo Vickerman, 2004;Parabodo Skuja, 1939;和克莱布斯，1892年。根据最近描述的这些双翅目动物的进食行为，我们认为它们是在进食含糖食物和喝水时被感染的，这就间接证明了血液不是它们唯一的食物和液体来源。

期刊介绍： FOLIA PARASITOLOGICA, issued in online versions, is an international journal that covers the whole field of general, systematic, ecological and experimental parasitology. It publishes original research papers, research notes and review articles. Contributions from all branches of animal parasitology, such as morphology, taxonomy, biology, biochemistry, physiology, immunology, molecular biology and evolution of parasites, and host-parasite relationships, are eligible. Novelty and importance in the international (not local or regional) context are required. New geographical records of parasites, records of new hosts, regional parasite and/or host surveys (if they constitute the principal substance of manuscript), local/regional prevalence surveys of diseases, local/regional studies on epidemiology of well known diseases and of parasite impact on human/animal health, case reports, routine clinical studies and testing of established diagnostic or treatment procedures, will not be considered. One species description will also not be considered unless they include more general information, such as new diagnostic characters, host-parasite associations, phylogenetic implications, etc. Manuscripts found suitable on submission will be reviewed by at least two reviewers.
