Abstract

The viviparous gyrodactylid genus Macrogyrodactylus Malmberg, 1957 is endemic to Africa, composed of nine species from hosts of four freshwater fish families, including catfishes (Siluriformes: Clariidae). Three species, Macrogyrodactylus clarii Gussev, 1961; M. congolensis (Prudhoe, 1957) and M. karibae Douëllou et Chishawa, 1995, are primarily known to parasitise the African sharptooth catfish Clarias gariepinus (Burchell) in various African countries. From November 2017 to September 2019, a total of 184 individuals of C. gariepinus were collected from selected localities in southern Africa and their skin, fins and gills were surveyed for monogeneans. Three species of Macrogyrodactylus (M. clarii, M. congolensis and M. karibae) were found parasitising C. gariepinus from five localities in South Africa and Zambia. Overall prevalence was 50% to 100% with intensities of up to 109 parasites per host individual. New locality records in southern Africa, morphological observations and additional molecular data on the complete Internal Transcriber Spacer (ITS-1-5.8S-ITS-2) regions of the rDNA gene for the three gyrodactylid species are presented in this study.

非洲南部Clarias gariepinus (siluriforma: Clariidae) 1957年新分布记录及分子资料(单属:Gyrodactylidae)。

Macrogyrodactylus Malmberg, 1957，是非洲特有的胎生gyrodactylus属，由4个淡水鱼科的9种组成，包括鲶鱼(siluriforma: Clariidae)。三种，Macrogyrodactylus clarii Gussev, 1961;M. congolensis (Prudhoe, 1957)和M. karibae Douëllou et Chishawa, 1995，主要寄生于非洲许多国家的非洲尖牙鲶鱼Clarias gariepinus (Burchell)。2017年11月至2019年9月，在非洲南部选定地点共采集了184只加里平棘鱼，并对其皮肤、鳍和鳃进行了单系调查。在南非和赞比亚的5个地区发现了3种寄生于加里平蝇的大螺线蝇(M. clarii, M. congolensis和M. karibae)。总体流行率为50%至100%，每个宿主个体的寄生虫密度高达109。本文报道了非洲南部三种旋虫的新地点记录、形态学观察和rDNA全区(ITS-1-5.8S-ITS-2)的额外分子数据。

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.
