Molecular phylogenetic analysis of an extensive collection of monozoic tapeworms of the genus Paracaryophyllaeus Kulakovskaya, 1961 (Cestoda: Caryophyllidea), parasites of loaches (Cypriniformes: Cobitidae) in Eurasia, has revealed cryptic species diversity within this long-time monotypic genus, especially in the Paracaryophyllaeus gotoi (Motomura, 1927) species complex [syn. Paracaryophyllaeus dubininorum (Kulakovskaya, 1961); type species]. Three independent, well-supported clades were discovered on the basis of molecular data: (i) specimens from Misgurnus anguillicaudatus and Cobitis lutheri from China, Russian Far East and Japan called herein P. cf. gotoi 1, which may be conspecific with P. gotoi (Motomura, 1927), although in the absence of sequence data for P. gotoi from its type locality (basin of the River Kumkan in Korea), no certain inferences about their identity can currently be made; (ii) specimens from M. anguillicaudatus from China and Japan - P. cf. gotoi 2, which are morphologically indistinguishable from those of P. cf. gotoi 1; and (iii) morphologically distinct tapeworms from the endemic loach Cobitis bilseli from southwestern Turkey (Beysehir Lake), which are described herein as a new species. Paracaryophyllaeus vladkae Scholz, Oros and Aydogdu n. sp. differs from the remaining species of the genus in the following characteristics: the testes begin anterior to the first vitelline follicles (versus posterior), the body is short and robust (versus more elongate and slender), and the scolex is wide, rounded or apically tapered (versus claviform to truncate). Species composition of the genus, host specificity of species and geographical distribution are briefly discussed. (C) 2014 Elsevier Ireland Ltd. All rights reserved.
Occurrence of helminth parasites in the Turkish endemic fish, squalius anatolicus (cyprinidae)
(Eur Assoc Fish Pathologists, 2015-01-01) Keskin, N.; Erk'akan, F.; İnnal, D.; Aydogdu, Ali; AYDOĞDU, ALİ; Bursa Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu.; 0000-0003-2778-0273; JCO-3521-2023
In this study, the occurrence of helminth parasites in Squalius anatolicus (Cyprinidae) of Sarisu stream (Beysehir - Konya) was investigated from spring 2009 to autumn 2010. S. anatolicus is endemic to Turkey, having very limited distributions. The conservation status of the fish has been referred to as endangered. During the study, a total of 83 Squalius anatolicus specimens were examined for helminth parasites. Two species of helminth parasites [Dactylogyrus vistulae (Monogenea: Dactylogyridae), Pomphorhynchus laevis (Acanthocephala: Pomphorhynchidae)] were found on 51 fish. Male hosts had higher levels of infection of both isolated parasite species. A total of 52 specimens of D. vistulae infected 10 of 83 fish examined, with prevalence and mean intensity of 12.04 % and 5.2 respectively. A total 203 specimens of P. laevis infected 48 of 83 fish examined, with prevalence and mean intensity of infection 57.8 % and 4.2 respectively. Prevalence and infection intensity, length classes, and sex compositions of host populations, as well as the seasonality of infection were obtained and the results compared with other studies. This study is the first parasitological survey of S. anatolicus in Turkey, adding to the knowledge of geographical distribution and host range of two parasite species.
