(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).
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.
Helminth parasites found in hedgehogs (Erinaceus concolor) from Turkey
(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.
Occurrence of metazoan parasites of the mirror carp (Cyprinus carpio L. 1758) in a fish farm, Uluabat, Bursa, Turkey
(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.
