The First Record of Gyrodactylus perccotti Ergens & Yukhimenko, 1973 (Monopisthocotyla: Gyrodactylidae), A Parasite of the Alien Chinese Sleeper (Perccottus glenii Dybowski, 1877), in Bulgaria
Purpose
The Chinese sleeper Perccottus glenii is native in East Asia and has become invasive in West Siberia and Europe. It was recorded in the Bulgarian section of the Danube in 2005. The aim of the present study is to report on the presence of gyrodactylid infection in this alien fish species.
Methods
In the spring of 2019, two specimens of P. glenii were caught from the Lake Srebarna Biosphere Reserve (Northeastern Bulgaria) and examined for ectoparasites. The gyrodactylid specimens found were studied morphologically in glycerine-gelatine mounts. The ITS1-5.8 S-ITS2 fragment of rDNA was analysed.
Results
Gyrodactylus perccotti, a specific parasite of the Chinese sleeper, was found on the caudal fin of one of the studied specimens with low abundance, two specimens only. The morphology and the DNA analysis showed full correspondence with the previously published data.
Conclusions
This finding represents the first record of G. perccotti from Bulgaria. The results of the present study increase the knowledge of the non-native geographical range of G. perccotti.
期刊介绍：
Acta Parasitologica is an international journal covering the latest advances in the subject.
Acta Parasitologica publishes original papers on all aspects of parasitology and host-parasite relationships, including the latest discoveries in biochemical and molecular biology of parasites, their physiology, morphology, taxonomy and ecology, as well as original research papers on immunology, pathology, and epidemiology of parasitic diseases in the context of medical, veterinary and biological sciences. The journal also publishes short research notes, invited review articles, book reviews.
The journal was founded in 1953 as "Acta Parasitologica Polonica" by the Polish Parasitological Society and since 1954 has been published by W. Stefanski Institute of Parasitology of the Polish Academy of Sciences in Warsaw. Since 1992 in has appeared as Acta Parasitologica in four issues per year.
