(Helminthological Soc Washington, 2015-01-01) Smales, Lesley R.; Aydoğdu, Ali; Emre, Yılmaz; AYDOĞDU, ALİ; Uludağ Üniversitesi/Mustafakemalpasa Meslek Yüksekokulu.; 0000-0003-2778-0273; JCO-3521-2023
Seven species of endemic freshwater fish, Aphanius anatoliae, Aphanius villwocki (Cyprinodontidae), Capoeta angorae, Capoeta erhani, Capoeta mauricii, Chondrostoma fahirae, and Pseudophoxinus fahrettini (Cyprinidae) from Turkey were examined for acanthocephalans. Acanthocephalus sp., Neoechinorhynchus zabensis, Pomphorhynchus spindletruncatus, and Paralongicollum nurtenae n. sp. were found. The new species can be distinguished from its congeners by a suite of characters including the shape of the proboscis, which has an armature of 16-22 rows of 10-13 hooks, the posterior most circle of hooks alternating. All are new host and locality records. The geographic distributions of N. zabensis and P. spindletruncatus in Turkey may be due in part to changes in glacial river system connections that have occurred since the Pleistocene.
Comparison of helminth species and their prevalence in rudd ( scardinius erythrophthalmus l. 1758) in Golbasi dam lake and Kocadere stream in Bursa province of Turkey
(Tubitak Scientific & Technological Research Council Turkey, 2008-01-01) Aydoğdu, Ali; AYDOĞDU, ALİ; Selver, Melih; Çırak, Veli Y.; ÇIRAK, VELİ YILGÖR; Bursa Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu.; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Parasitoloji Anabilim Dalı.; 0000-0003-2778-0273; JCO-3521-2023
Variations in the helminth species parasitizing the rudd, Scardinius erythrophthalmus L., and their prevalences were compared in 2 different localities (Golbasi Dam Lake and Kocadere Stream) in Bursa province in northwestern Turkey. The overall prevalences of helminth infections were 46.7% and 92.3% at Golbasi Lake and Kocadere Stream, respectively. The following helminths were detected: Dactylogyrus difformis, Diplostomum spathaceum metacercariae, Asymphlodora markewitschi, Ligula intestinalis plerocercoids, Skrajibillanus scardinii, Eustrongylides sp. larvae, and Hysterothylacium sp. larvae. Among these species, D. difformis and D. spathaceum were recorded at both sampling stations. However, D. difformis was the dominant species in rudd in Golbasi Lake (overall prevalence 40%) while D. spathaceum was prevalent in Kocadere Stream ( overall prevalence 80.7%). L. intestinalis plerocercoids were present only in Golbasi Lake, while S. scardinii, A. markewitschi, Eustrongylides sp. larvae, and Hysterothylacium sp. were detected only in Kocadere Stream. It is concluded that within the same fish species the distribution of helminths and their prevalence vary substantially, especially for some parasites, between 2 different habitats ( lake and stream).
Contrasting phylogeography of two Western Palaearctic fish parasites despite similar life cycles
(Wiley, 2018-01) Perrot-Minnot, Marie-Jeanne; Spakulova, Marta; Wattier, Remi; Kotlik, Petr; Duşen, Serdar; Tougard, Christelle; Aydoğdu, Ali; Uludağ Üniversitesi/Veterinerlik Fakültesi/Su Hayvanları Hastalıkları Bölümü.; 0000-0003-2778-0273; JCO-3521-2023; 6701819349
Aim: We used comparative phylogeography of two intestinal parasites of freshwater fish to test whether similarity in life cycle translates into concordant phylogeographical history. The thorny-headed worms Pomphorhynchus laevis and P. tereticollis (Acanthocephala) were formerly considered as a single species with a broad geographical and host range within the Western Palaearctic. Location: Central and eastern parts of Northern Mediterranean area, Western and Central Europe, Ponto-Caspian Europe. Methods: A mitochondrial marker (COI) was sequenced for 111 P. laevis and 50 P. tereticollis individuals and nuclear ITS1 and ITS2 sequences were obtained for 37 P. laevis and 21 P. tereticollis. Genetic divergence, phylogenetic relationships and divergence time were estimated for various lineages within each species, and their phylogeographical patterns were compared to known palaeogeographical events in Western Palaearctic. Biogeographical histories of each species were inferred. Results: The two species show very different phylogeographical patterns. Five lineages were identified in P. laevis, partially matching several major biogeographical regions defined in the European riverine fish fauna. The early stages of P. laevis diversification occurred in the peri-Mediterranean area, during the Late Miocene. Subsequent expansion across Western Europe and Russia was shaped by dispersal and vicariant events, from Middle Pliocene to Middle Pleistocene. By contrast, P. tereticollis has differentiated more recently within the Western and Central parts of Europe, and shows weak geographical and genetic structuring. Conclusion: Our study highlights weak to moderate similarity in the phylogeographical pattern of these acanthocephalan parasites compared to their amphipod and fish hosts. The observed differences in the timing of dispersion and migration routes taken may reflect the use of a range of final hosts with different ecologies and dispersal capabilities. By using a group underrepresented in phylogeographical studies, our study is a valuable contribution to revealing the biogeography of host-parasite interactions in continental freshwaters.

Helminth communities of the roach (Rutilus rutilus) from Kocadere stream in Bursa, Turkey: Occurrence, intensity, seasonality and their infestations linked to host fish size
(Eur Assoc Fish Pathologists, 2009) Selver, Melih; Aydoğdu, Ali; Çırak, Veli Yılgör; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu.; Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı.; 22981630000; 6701819349; 6602404057
Helminth communities and their prevalence, intensity and abundance were studied with respect to seasonal variation and host size in a population of roach (Rutilus rutilus) from Kocadere stream, Turkey. A total of 113 individuals of roach were examined for helminth parasites from February 2005 to January 2006. Of the 113 R. rutilus, 72 (63.7%) were found to be infected by one or more parasite species. In total, four helminth parasite species were identified: Monogeneans - Dactylogyrus crucifer; Cestoda - Bothriocephalus acheilognathi; Nematoda - Eustrongylides sp. larvae, and Contracaecum sp. larvae. D. crucifer was the most common species in this study and a total of 1946 specimens were recorded on 66 fishes. The abundance of D. crucifer varied highly significantly during the investigation period and increased from February to March-April (peak), followed by a sharp decrease thereafter. As regards the abundance of the parasite species depending on the fish length, the highest frequency of distribution of D. crucifer was found on host with 18.5 - 21.5 cm. However, no correlation existed between fish length and parasite abundance (r = -0.08; p>0.001). The overall prevalence and mean intensity were 58.4% and 29.4, respectively. The infection levels peaked (100%) in April, May and July. This species was not detected in the November and December samples. Two B. acheilognathi were found in one fish (0.8%) whereas Eustrongylides sp. larvae and Contracaecum sp. larvae were recorded in four (3.5%) and one (0.8%) fish examined, repectively.

(Elsevier, 2010-10-01) Çırak, Veli Yilgör; Şenlik, Bayram; Aydoğdu, Ali; Selver, Melih; Akyol, Volkan; Uludağ Üniversitesi/Veterinerlik Fakültesi/Klinik Öncesi Bilimler Bölümü.; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu.; 0000-0003-2964-2245; 6602404057; 9332720500; 6701819349; 22981630000; 8943998500
Hedgehog diseases are becoming important issues for veterinary surgeons due to growing interest in this animal species among pet owners and an increase in cases of rescued hedgehogs requiring veterinary care. A parasitological study was carried out on hedgehogs (Erinaceus concolor) in the Bursa province of Turkey, found dead mainly due to road casualties, to determine their helminth parasite burden. The detected helminths and their prevalences were as follows: Physaloptera clausa (72.2%), Crenosoma striatum (55.5%), Aonchotheca erinacei (55.5%), Hymenolepis erinacei (55.5%), Nephridiorhynchus major (50%) and Eucoleus aerophilus (22.2%). The number of parasites in infected animals varied from 1 to 203. The highest mean intensity of infection was observed with C striatum, and the lowest was observed with N. major. The mean abundance of different species varied from 0.7 to 41.8, where E. aerophilus and C striatum had the lowest and highest abundance, respectively. This study represents the first time N. major and E. aerophilus have been reported in hedgehogs in Turkey. The presence of E. aerophilus and its potential role as a zoonotic agent are discussed.

(Inst Zoology, Bas, 2021-12-01) Emre, Yılmaz; Emre, Nesrin; Yabacı, Aysegül; Aydoğdu, Ali; AYDOĞDU, ALİ; Bursa Uludağ Üniversitesi/Veteriner Fakültesi.; 0000-0003-2778-0273; JCO-3521-2023
Two endemic freshwater cyprinid fishes, Capoeta caelestis Schoter, Ozulug & Freyhof, 2009 and C. angorae (Hanko, 1925), have been studied for the presence of parasitic nematodes in Firmz Stream, K. Mara, Goksu River, Antalya, in the Anatolian Region of Turkey. Only a species of the genus Rhabdo-chona was found in intestines and identified as R. fortunatowi Dinnik, 1933. Totally, 104 specimens of R. fortunatowi infected 19 out of 99 individuals of C. caelestis (prevalence 19.1 %, mean intensity 5.4). In C. angorae, 40 specimens of R. fortunatowi infected 15 out of 178 fish individuals (prevalence 8.4 %, mean abundance 2.6). Prevalence and intensity of R. fortunatowi infection were calculated across the seasons as well as in age groups and sexes of hosts. The present study provides the first record of R. fortunatowi in Turkey and the first host records of this parasite in both C. caelestis and C. angorae, thus expanding the known geographical and host range of this nematode species.
The occurrence of helminth parasites (Nemathelminthes) in some freshwater fish from streams discharging into antalya bay in Antalya, Turkey: Two new host records from Antalya
(TÜBİTAK, 2011) Emre, Yılmaz; Emre, Nesrin; Aydoğdu, Ali; Altunel, Fayik Naci; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Anabilim Dalı.; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksek Okulu.; 6701819349; 7801410280
A total of 65 individuals from 3 different fish species, Capoeta antalyensis (n: 15), Aphanius mento (n: 29), and Pseudophoxinus battalgil (n: 21), were examined for helminth parasites (Nemathelminthes) between May and July of 2009. A total of 123 parasites of 3 species were found in these fish, consisting of 3 nematodes: Rhabdochona denudata, Eustrongylides excisus larvae, and Contracaecum sp. larvae. Among these species, R. denudata was recorded in the intestine of C. antalyensis, with a total of 92 parasites found in 13 of the 15 C. antalyensis examined. The overall prevalence of this species was 86.6%. Two further species of nematodes, Contracaecum sp. larvae and E.. excisus larvae, were found in the abdominal cavities of P battalgil and A. mento, respectively. Contracaecum sp. larvae were found in 10 of 21 fish examined and a total of 29 specimens were recorded, making the overall prevalence of this species 47.6%. Only 2 E. excisus larvae were found in 2 of the 29 fish examined. This study provides the first ichthyoparasitological data for these host fish species in Turkey, and the occurrence of R. denudata in C. antalyensis and Con tracaecum sp. larvae in P battalgil are considered to be new host records for these fish species.

(Zoological Soc Pakistan, 2009) Aydoğdu, Ali; Selver, Melih; Aydın, Cenk; Uludağ Üniversitesi/Veteriner Fakültesi/Klinik Öncesi Bilimler Bölümü.; Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Fizyoloji Anabilim Dalı.; 6701819349; 22981630000; 7005426982
Metazoan parasite of the mirror carp (Cyprinus carpio L.) in a fish farm ponds, Bursa, Turkey was investigated from April 2005 to March 2006. Sixty four out of 79 mirror carps were infected with one or more of the four parasite species - Dactylogyrus extensus, D. anchoratus and Paradiplozoon homoion (Monogenea) on the host gills and Argulus foliaceus (Crustacea) on oral cavitiy, gills, fins and skin. D. extensus was the most frequent having an overall prevalence of 39.2%. P. homoion was 54.4%. The third most prevalent parasite was D. anchoratus with overall prevalence of 25.3%. A. foliaceus showed overall prevalence of 43.03%. At the end of this study, when P. homoion was recorded as parasite species being the highest overall prevalence, D. extensus was observed in the highest intensity. D. extensus, D. anchoratus and P. homoion were recorded for the first time in the mirror carp in Turkey.
The occurrence of the helminth fauna in sand goby (Gobius fluviatilis Pallas, 1811) from Lake Uluabat, Turkey
(Sciendo, 2002) Öztürk, Okan Murat; Doğan, İnci; Aydoğdu, Ali; Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Biyoloji Bölümü.; 6701819349
Helminth parasites of sand goby (Gobius fluviatilis Pallas, 1811) from Lake Uluabat were investigated on a monthly or bimonthly basis between April 1998 and November 1999. Four species of helminth parasites were recorded in 98 out of 134 fish: Gyrodactylus gobii Shul'man, 1953; Bothriocephalus acheilognathi Yamaguti, 1934; Ligula pavlovskii Dubinina, 1959; Eustrongylides excisus Jagerskold, 1909. They were evaluated with respect to seasons and host size. While G. gobii appeared to infect the gills and the skin of host fish, B. acheilognathi established itself in the intestines, and E excisus and L. pavlovskii in the body cavity. A total of 789 specimens of G. gobii were detected especially on smaller host fish during the spring period (prevalence 25.3%, mean intensity 23.21 +/- 9.17 specimens/fish). Although 184 B. acheilognathi appeared on host fish of various sizes and in all seasons, the mean intensity of infection was relatively low (prevalence 34.3%, mean intensity 3.98 +/- 3.15 specimens/fish). Concerning L. pavlovskii, the second cestode species, only 9 parasites were found in medium-sized host fish during the summer, autumn and winter (prevalence 3.7%, mean intensity 1.60 +/- 0.89 specimens/fish). A total of 108 parasite specimens of E. excl. sus was found on 40 host fish in the summer and autumn (prevalence 29.8%, mean intensity 2.70 +/- 2.29 specimens/fish). The present study gives the occurrence, density, seasonal changes, and parasite-host size relationship for a new locality -Lake Uluabat- as a contribution to the geographical distribution of G. gobii and E. excisus in sand goby.
Pomphorhynchidae and quadrigyridae (Acanthocephala), including a new genus and species (Pallisentinae), from freshwater fishes, cobitidae and cyprinodontidae, in Turkey
(Folia Parasitologica, 2012-09) Smales, Lesley R.; Emre, Yılmaz; Aydoğdu, Ali; Uludağ Üniversitesi/Mustafakemalpaşa Meslek Yüksekokulu.; 6701819349
During a survey of freshwater fishes from Turkey two species of Acanthocephala, one of them new, were found. Pomphorhynchus tereticollis (Pomphorhynchidae) is reported at 24% prevalence in 37 Cobitis bilseli (Cobitidae) from Lake Beysehir, Konya, for the first time. The eoacanthoacaphalan Triaspiron aphanii gen. n. et sp. n. (Quadrigyridae), at a prevalence of 90%, is described from 29 Aphanius mento (Cyprinodontidae), from Kirkgoz Springs, Antalya. The new genus most closely resembles Raosentis Datta, 1947, both having a small spindle shaped trunk, and Acanthogyrus Thapar, 1927, both having a proboscis armature of three circles of hooks. Triaspiron differs from Raosentis in proboscis shape, cylindrical not globular, proboscis armature, three circles, a total of 16 hooks in all, not four circles, a total of 26-30 hooks in all, and trunk spination, two fields of spines in the anterior field with spines arranged in up to 40 circular rows, not a single field with 9-17 rows of spines. Triaspiron differs from Acanthogyrus in having fewer proboscis hooks, 16 compared with 18-24, arranged in three circles, one anterior and two posteriorly placed, with an unarmed region between, not three circles of hooks evenly spaced, and two fields of trunk spines, not one.

Economically important sparid fish species, gilthead (Sparus aurata) and white seabream (Diplodus sargus) (Sparidae) are frequently parasitised by diplectanid monogeneans, known to induce severe losses in farming conditions. We have analysed population dynamic of two diplectanid species, Lamellodiscus echeneis and Lamellodiscus ignoratus (Monogenea: Diplectanidae) collected from two bream species in the Beymelek Lagoon (southwest coast of Turkey), comparing it between different host variables (fish size, age and sex) in order to have insight in parasites' ecology, important for managing parasitosis in the intensive aquaculture system. In seabream (N = 127), L. echeneis prevalence was 46.5 % (exact 95 % confidence limits 38.90-54.14), mean abundance 5.64 (bootstrap 95 % confidence limits 4.20-7.65) and mean intensity 12.14 (bootstrap 95 % confidence limits 9.49-15.59). In white seabream (N = 102), L. ignoratus prevalence was 24.5 % (exact 95 % confidence limits 16.53-34.03), mean abundance 1.73 (bootstrap 95 % confidence limits 0.98-3.21) and mean intensity 7.04 (bootstrap 95 % confidence limits 4.60-11.40). Parasites' parameters differed only between seasons in both hosts and between age categories in gilthead, but not in white seabream.
