Publication Helminth parasites of the Turkish smooth newt, lissotriton schmidtleri (raxworthy, 1988) and balkan crested newt, triturus ivanbureschi arntzen et wielstra, 2013 from İzmir, Turkey(Folium Publ Co, 2023-01-01) Olgun, Kurtuluş; Avcı, Aziz; Uzum, Nazan; Ilgaz, Çetin; BİRLİK, SEZEN; Yıldırımhan, Hikmet Sami; YILDIRIMHAN, HİKMET SAMİ; Fen Edebiyat Fakültesi; Biyoloji Bölümü; AAB-9963-2020; AAC-1581-2020May 23, We studied the helminths parasitizing the individuals of the Turkish smooth newt, Lissotriton schmidtleri (n = 60) and the Balkan crested newt, Triturus ivanbureschi (n = 40) collected from two localities in Izmir, Turkey. Of the 100 newts, 20 (20%) were infected. We detected only one species of parasites, Megalobatrachonema terdentatum (Nematoda: Kathlaniidae), with a prevalence of 0.13% and 0.30% in L. schmidtleri and T. ivanbureschi, respec-tively. Triturus ivanbureschi represents a new host record for M. terdentatum. Also we present new locality re-cords for both hosts and helminth species.Publication Helminths of the digestive tract in buteo buteo (Falconiformes: Falconidae) in Bursa province of northwest Turkey(Tübitak Bilimsel ve Teknolojik Araştırma Kurumu, 2015-01-01) Tezel, Mehmet; Girişgin, Ahmet Onur; Birlik, Sezen; Yıldırımhan, Hikmet Sami; Şenlik, Bayram; Tezel, Mehmet; GİRİŞGİN, AHMET ONUR; BİRLİK, SEZEN; YILDIRIMHAN, HİKMET SAMİ; ŞENLİK, BAYRAM; Veteriner Fakültesi; Parasitoloji Bölümü; 0000-0002-0020-2708; 0000-0003-2964-2245; AAB-9963-2020; B-5286-2017; AAC-1581-2020; CDI-4443-2022; GBN-0139-2022Raptors can be parasitized by numerous helminth species due to their feeding behavior. When the parasite load is high, the bird's life can be affected. A total of 21 common buzzards, Buteo buteo, from different districts of Bursa, in Northwest Turkey, were examined for helminth infections. The results of the postmortem examination revealed that 15 of 21 buzzards (71.43%) harbored 1 or more helminth species. Seven species/genera of helminths were detected at the following prevalence rates: ascarid larvae (47.62%), Strigea falconis (38.09%), Neodiplostomum attenuatum (33.33%), Cladotaenia globifera (14.29%), Centrorhynchus amphibius (14.29%), Physaloptera alata (9.52%), and Synhimantus laticeps (4.76%). The most common helminth species was S. falconis, which was found in the small intestine of its hosts. This study is the first report to describe the presence of N. attenuatum, S. falconis, C. globifera, P. alata, and C. amphibius in the common buzzards of Turkey. This study is also the first to report the presence of S. laticeps in common buzzards, although this helminth had been previously reported in a sparrow hawk in Turkey.Publication Exploring the anthelmintic activity of Olea europaea L (Olive) leaves extract and oleuropein in mice naturally infected with Aspiculuris tetraptera(Sciendo, 2023-09-01) Kamran, Muhammad Adeel; YIldIrımhan, Hikmet Sami; Şenlik, Bayram; Kamran, Muhammad Adeel; YILDIRIMHAN, HİKMET SAMİ; ŞENLİK, BAYRAM; Fen Edebiyat Fakültesi; Parazitoloji Ana Bilim Dalı; 0000-0003-2964-2245; AFN-9439-2022; AAC-1581-2020; GBN-0139-2022Oxyuriasis, caused by the nematode Enterobius vermicularis, is one of the cosmopolitan intestinal infections of humans. Aspiculuris tetraptera commonly infects mice and it is morphologically similar to E. vermicularis. Parasitic resistance reduces the efficiency of synthetic drugs and poses economic impacts on the dairy sector, thus necessitating novel anthelmintic agents. Olea europaea L. (Olive) is a bioactive plant with potent pharmacological activities. However, its effects on oxyurids are poorly known, and no studies are currently exploring olives' anthelmintic potential. In this study, we investigated the pharmacokinetic behaviors of O. europaea leaves extract (OLE) and its phenolic compound oleuropein in mice infected with A. tetraptera, in comparison with Albendazole (ABZ), a standard drug used to treat parasitic worms. Fecal flotation method was used to identify the infestation with A. tetraptera eggs by examining the stool samples from mice. Infected animals were divided into 7 groups. 250 mg/kg, 500 mg/kg, and 1000 mg/kg doses of OLE, 5 mg/kg and 20 mg/kg doses of oleuropein, 10 mg/kg of ABZ and tap water were orally administered by gavage for 7 days during treatments. Drug efficacies and statistical differences between the treatments and controls were evaluated. Our results revealed 92.43 % efficacy of ABZ, similar to 92.19 % efficacy of 1000 mg/kg of OLE. At the same time, 250 mg/kg and 500 mg/kg concentrations of OLE remained 70.03 % and 63.18 % effective in reducing worm counts. Efficacy percentages of 5 mg/kg and 20 mg/kg of oleuropein were 9.27 % and 70.56 %, respectively. Statistical analysis of ABZ was significant compared to 1000 mg/kg of OLE, which was almost equal but insignificant. In general, our results confirm the anthelmintic potential of OLE and oleuropein against mice pinworms and open the way for targeted extraction of bioactive compounds from plants to optimize its use in human and veterinary medicine.Publication Endoparasites of the golden grass skink heremites auratus (linnaeus, 1758) (squamata: Scincidae) from Turkey(Helminthological Soc Washington, 2021-01-01) Sumer, Nurhan; Bursey, Charles R.; Yildiz, Mehmet Zulfu; Eylek, Buket; Kamran, Muhammad Asad; Akman, Bahadir; Yildirimhan, Hikmet Sami; YILDIRIMHAN, HİKMET SAMİ; Eylek, Buket; Kamran, Muhammad Asad; Fen Edebiyat Fakültesi; Biyoloji Ana Bilim DalıWe examined 35 golden grass skinks Heremites auratus (Linnaeus, 1758) (Squamata: Scincidae), obtained from various locations in Turkey, for helminth parasites.

Their broad diet makes them especially susceptible to a variety of helminths. We conducted a survey of intestinal helminths of L. michahellis to determine the diversity of intestinal parasites. Thirty-five yellow-legged gulls were necropsied, and helminths were examined via light microscopy. Twenty-three of 35 (65%) of hosts examined were infected with the following helminths: 6 Digenea species (Acanthotrema armata, Brachylaima aspersae, Cryptocotyle lingua, Diplostomum spathaceum, Knipowitschiatrema sp., and Stephanoprora denticulata); 5 Cestode species (Alcotaenia microcantha, Diphyllobothrium dentriticum, Microsomacanthus ductilis, Monopylidium galbulae, and Tetrabothrius erostris); and 2 Nematode species (Contracaecum rudolphii and Synhimanthus sp.). Herein, the intestinal parasite diversity of yellow-legged gulls from Turkey is reported, and new geographical records are documented.Publication Intestinal helminth parasites of two bat species of the genus myotis kaup, 1829 (Chiroptera: Vespertilionidae) from Turkey, with DNA sequencing of helminth nuclear LSR rDNA(Inst Zoology, Bas, 2019-06-01) Sümer, Nurhan; Yıldırımhan, Hikmet Sami; SÜMER, NURHAN; YILDIRIMHAN, HİKMET SAMİ; Fen Edebiyat Fakültesi; Biyoloji Bölümü; AAH-4193-2021; AAC-1581-2020Three individuals of Myotis alcathoe von HeIversen & Heller, 2001 (males) and twenty three individuals of Myotis daubentonii (Kuhl, 1817) (three females and twenty males) from Bursa Province, Turkey, were examined for helminth parasites. Myotis alcathoe was found to harbour four species of digeneans: Prosthodendrium ascidia, Lecithodendrium linstowi, Plagiorchis koreanus and Plagiorchis elegans. Myotis daubentonii was found to harbour eight species of digeneans: Prosthodendrium chilostomum, Prosthodendrium longiforme, Prosthodendrium hurkovae, Lecithodendrium linstowi, Plagiorchis koreanus, Plagiorchis muelleri, Plagiorchis elegans and Plagiorchis vespertilionis, as well as two species of nematodes: Capillaria moraveci and Molinostrongylus skrjabini. All these species were identified using both morphological and molecular methods, obtaining consistent results.
