Publication Long term investigations on tick infestations of human(Kafkas Üniversitesi Veteriner Fakultesi Dergisi, 2015-11-01) Selçuk, Özgür; Aydın, Levent; Girişgin, Ahmet Onur; Şenlik, Bayram; Özakin, Cüneyt; Selçuk, Özgür; AYDIN, LEVENT; GİRİŞGİN, AHMET ONUR; ŞENLİK, BAYRAM; ÖZAKIN, CÜNEYT; Uludağ Üniversitesi/Veteriner Fakültesi/Mikrobioloji Bölümü; Uludağ Üniversitesi/Veteriner Fakültesi/Parasitoloji Bölümü; 0000-0002-0020-2708; 0000-0003-2964-2245; AAG-8392-2021; B-5286-2017; JLA-7878-2023; HLG-4450-2023; GBN-0139-2022In this study, a total of 19866 samples which were collected from humans who applied to the hospitals with tick bites in the western part of Turkey (Bursa) between the years 2007 and 2011 (from February to November) were examined. Approximately 10% (1985) of samples were found as non-ticks like bee stings, lice, fleas and other arthropods. The ticks were identified as Rhipicephalus spp. (72.98%), Ixodes spp. (18.96%), Hyalomma spp. (7.18%), Dermacentor marginatus (0.027%) and Haemaphysalis parva (0.005%). Based on localities, majority of the tick samples were reported from the urbanized areas (81%). Especially, Ixodes spp. species were commonly found in highland and forestry areas of Bursa.Publication The efficiency of toltrazuril, thymol, and toltrazuril plus thymol combination on eimeriosis in lamb(TÜBİTAK, 2023-03-17) Özüiçli, Mehmet; Girişgin, Ahmet Onur; Kısadere, İhsan; Diker, Ali İhsan; Candar, Ali Erdi; Aydın, Levent; GİRİŞGİN, AHMET ONUR; AYDIN, LEVENT; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Enstitüsü/Biyoistatistik Anabilim Dalı.; 0000-0002-0020-2708; B-5286-2017; HLG-4450-2023This study aimed to evaluate and compare the efficacy of the treatment with a single dose of toltrazuril 5% (Baycox), thymol (Versatile, Nine Life, United Arab Emirates), and toltrazuril + thymol combination to control Eimeria spp. infection in lambs in intensive feeding. The study was designed with five groups and these groups aligned as; group 1 (negative control group; NEG), group 2 (positive control group; POZ), group 3 (thymol; THY), group 4 (toltrazuril; TOL) and group 5 [(thymol + toltrazuril; (THY + TOL)]. Each group consisted of 26 Merino lambs which are 60-75 days old each. Treatment groups were administered orally as a single dose [(40 mg/kg/ bw THY (crystal formulation, 100% purity (with feed), 20 mg/kg/bw TOL, THY + TOL [(40 mg/kg/bw THY (with feed) + 20 mg/kg/bw TOL)] and the groups were compared each other in terms of efficacy, fecal scoring, and body weight gain. In addition, Eimeria species identification was also performed. Eimeria ahsata was the most abundant species in infected lambs. Treatment efficacy was found to be 75.15% in the THY, 99.50% in the TOL, and 95.42% in the THY + TOL groups. In conclusion, a single dose of TOL and THY + TOL were found to be highly effective in both clinical and subclinical eimeriosis in lambs. In addition, although single usage of THY is not effective in clinical coccidiosis, it can be used prophylactically in subclinical infections. To find out the anticoccidial effects of THY, it needs more studies to administer different and repeated doses.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; Uludağ Üniversitesi/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 A preliminary molecular study on the haplotypes of varroa destructor in Turkey(Israel Veterinary Medical Assoc, 2022-06-01) Utuk, A. E.; Doğan, O.; Tokgöz, E. A.; Girişgin, A. O.; Ozuicli, M.; Saygin, B.; GİRİŞGİN, AHMET ONUR; Saygın, Berna; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı.; 0000-0002-0020-2708 ; B-5286-2017; FVZ-6386-2022Varroosis is one of the most important diseases of honeybees. Four species, Varroa jacobsoni,Varroa destructor, Varroa underwoodi and Varroa rindereri are present in the genus of Varroa, the most prevalent one being V. destructor. V. destructor has different haplotypes which have different pathogenic effects on the honeybees. Korean (K) haplotype is more prevalent and pathogenic than the Japanese (J) haplotype. The aim of this study was to determine the haplotypes of V. destructor in Turkey. Female mites from ten different provinces of Turkey were examined. After DNA extraction partial sequences of mitochondrial COX1 gene was amplified with PCR and subsequently sequenced. At the conclusion of molecular and phylogenetic analysis, we determined that all isolates were identical to each other and corresponded with the K haplotype of V. destructor, with 100% identity. This study supports preliminary data regarding the haplotypes of V. destructor from Ankara, Cankiri, Corum, Elazig, Kirsehir, Kirikkale, Hakkari, Hatay, Samsun and Tekirdag provinces of Turkey. Considering that Turkey is a bridge between Asia, Europe and Africa, more detailed studies should be conducted for the determination of different haplotypes or variants of V. destructor.Publication A survey of the ectoparasites found on wild birds in northwest Turkey(Agricultural Research Communication Centre, 2023-08-01) Girişgin, O.; GİRİŞGİN, OYA; Girişgin, Ahmet Onur; GİRİŞGİN, AHMET ONUR; Çimenlikaya, N; Saygın, Berna; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Karacabey Meslek Yüksekokulu.; Bursa Uludağ Üniversitesi/Sağlık Bilimleri Fakültesi.; 0000-0002-0020-2708; B-5286-2017; JRY-1676-2023Background: Turkey is home to various resident and migratory wild bird species. The aim of the present study was to investigate the ectoparasites found on 188 injured or rescued resident and migratory wild birds from Bursa and surroundings between 2015 and 2019.Methods: Sampled birds were examined for different ectoparasites and all of the collected parasites were placed into tubes containing 70% ethyl alcohol. After mounting onto slides or fixing onto a plate, each parasite was identified to species using a light or stereo microscope.Result: Results revealed that 88 (46.8%) of the examined wild birds were infested with one or two of 3 different species of ectoparasites. The species identified were 38 lice, three ticks and two flies. The lice were highly prevalent (40.4%) species than the flies (2.1%) and ticks (2.1%). The results also first geographically documented the lice and ked fly species as follows, with additional new host records: Fulicoffula gallinula and Pseudomenapon pilosum in the common moorhens (Gallinula chloropus); Ciconiphilus decimfasciatus in the grey heron (Ardea cinerea); Saemundssonia clayae in the Eurasian woodcock (Scolopax rusticola); Ardeicola ixobrychae in the common little bittern (Ixobrychus minutus) and the ked fly as Ornithophila metallica in the Eurasian magpies (Pica pica) in Turkey. The study results provided valuable data on the ectoparasites living on migratory and resident bird species during their migration throughout northwest Turkey. Further research on the related pathogens that these ectoparasites harbor is in need.Publication Investigation of the bee-repellent properties of cotton fabrics treated with microencapsulated essential oils(Sage, 2019-04-01) Eyüpoğlu, Şeyda; Kut, Dilek; Girişgin, Ahmet Onur; Eyüpoğlu, Can; Özüiçli, Mehmet; Dayıoğlu, Habip; Civan, Mustafa; Aydın, Levent; KUT, YAŞAR DİLEK; GİRİŞGİN, AHMET ONUR; ÖZÜİÇLİ, MEHMET; AYDIN, LEVENT; Bursa Uludağ Üniversitesi/Tıp Fakültesi/Parazitoloji Anabilim Dalı; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Tekstil Mühendisliği Bölümü; 0000-0002-0020-2708; 0000-0002-9059-0838; AAH-4335-2021; B-5286-2017; FQC-4674-2022; HLG-4450-2023In this study, to produce single-use bee-repellent fabrics, a variety of essential oils were encapsulated with gum arabic wall material at a 1:5 ratio of wall to the core substance. The following core substances were used: lavender oil, laurel oil, fennel oil, N, N-diethyl-3-methylbenzamide (DEET), lavender + laurel oil, lavender + fennel oil, laurel + fennel oil, lavender + fennel + laurel oil, lavender oil + DEET, fennel oil + DEET and laurel oil + DEET. Lavender, fennel and laurel oils were analyzed by high-performance liquid chromatography. In this context, 11 different microcapsules were produced. After the microencapsulation process, the microcapsules were analyzed with a light microscope and by Fourier transform infrared spectroscopy. Furthermore, an image processing application was developed and implemented to determine the particle size distribution of the microcapsules. After the analysis of the microcapsules, cotton fabric samples were treated with the microcapsules. In order to analyze the microcapsules on the fabric samples, scanning electron microscopy (SEM) was used. To analyze the bee-repellent abilities of the fabric samples, 12 different measurement cabinets made of pine tree and glass were produced. According to the results, lavender and fennel oils can be used as bee-repellent alternatives to DEET in beekeeping.Publication Ectoparasites of hedgehogs (Erinaceus concolor) from Turkey(Schluetersche Verlagsgesellschaft Mbh & Co Kg, 2015-07-01) Girişgin, Ahmet Onur; Şenlik, Bayram; Aydın, Levent; Çırak, Veil Yılgör; GİRİŞGİN, AHMET ONUR; ŞENLİK, BAYRAM; AYDIN, LEVENT; ÇIRAK, VELİ YILGÖR; Uludağ Üniversitesi/Veteriner Fakültesi/Parasitoloji Bölümü; 0000-0002-0020-2708; 0000-0003-2964-2245; B-5286-2017; GBN-0139-2022; HLG-4450-2023; CKL-2130-2022Hedgehogs are small, nocturnal, spiny-coated animals that have been growing in popularity as exotic pets. However, these animals are host to a wide variety of viruses, bacteria, fungi and parasites, some of which are of zoonotic character. Thus, because hedgehogs have a potential role to transmit zoonoses including arthropod-borne diseases, we examined them for their ectoparasites. The study was carried out on hedgehogs found dead mainly due to road casualties in the Bursa province of Turkey. The ectoparasites were collected by both insecticide spraying of the body and inspection on a white paper carefully. Totally three species of ticks (Rhipicephalus sanguineus, Hyalomma aegyptium, Haemaphysalis parva) and one flea species (Archeopsylla erinacei) were detected. The prevalence of mixed infestation with both ticks and fleas was 45.5%. Haemaphysalis parva was reported for the first time from hedgehogs (Erinaceus concolor) in Turkey. The occurrence of ectoparasites and their potential role as vectors of certain zoonotic diseases are briefly discussed.Publication Hypothetical study of small hive beetle aethina tumida infestation in honeybees, risk commodities and probabilities for its introduction in Turkiye(Kafkas Üniversitesi Veteriner Fakültesi Dergisi, 2022-10-10) Girişgin, Ahmet Onur; Aydın, Levent; Yörük, Yunus Emre; GİRİŞGİN, AHMET ONUR; AYDIN, LEVENT; Yörük, Yunus Emre; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı; 0000-0002-0020-2708; 0000-0002-2875-8003; 0000-0002-6412-0744; B-5286-2017; HLG-4450-2023; JIU-3315-2023Turkiye is the second-largest honey producer globally; however, the export of honey and bee products does not adequately support the beekeeping industry. Pests account for the largest share of expenditure for agents found in honeybees in the country. Although the Small Hive Beetle (SHB) has not been detected in Turkiye, a risk assessment was performed to determine what happens if it enters the country. The risk assessment included: a) hazard identification; b) risk pathway determination; c) risk assessment for entry via the identified pathways; and d) outcome assessment for becoming endemic in Turkiye. The Risk AMP add-in program was used to assess the probability of distribution for each method of entry, pathway, and simulation. According to the simulations, the probability of SHB introduction in Turkiye varies from 0.17 per 1000 events/days (1.7 per 10000 days or 27 years) to 0.6 per 1000 events/imports (6 per 10000 days or 27 years). The highest likelihood of introduction comes from fruit import (11/15) and soil/compost import (4/15). The mean probability of introducing SHB infestation after 1000 iterations of the constructed model is 0.37 per 1000 events/days (3.7 within 10000 days or 27 years). Finally, the simulated average cost of SHB after the possible introduction is 523 million US $ for Turkiye. With these simulated data, risk assessment of a non-detected pest, SHB, was determined for Turkiye.Publication Prevalence of anoplocephalidae-infections according to fecal examination in sport horses(Ankara Üniversitesi, 2015-01-01) Gülegen, Ender; Girişgin, Ahmet Onur; Girişgin, Oya; Çırak, Veli Yılgör; Gülegen, Ender; GİRİŞGİN, AHMET ONUR; GİRİŞGİN, OYA; ÇIRAK, VELİ YILGÖR; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Sağlığı ve Hayvansal Üretim, Araştırma ve Uygulama Merkezi; Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı; Uludağ Üniversitesi/Karacabey Meslek Yüksek Okulu; 0000-0002-0020-2708; 0000-0001-9896-1093; JRY-1676-2023; B-5286-2017; JJV-7704-2023; JIT-4266-2023Aim of the present study was to determine the prevalance of Anoplocephalidae infections on enterprices where horses are kept for sport purposes (race, jumping, etc). A total of 460 horses of different age, gender and breed from 18 centres located in Bursa, Balikesir, Kocaeli, Tekirdag and Eskisehir were examined. Individual faecal samples were collected per rectum or freshly voided faeces. The samples were examined by means of sedimentation+centrifugation-flotation technique used saturated sugar solution (d=1.3) as medium. Anoplocephalidae-eggs were detected in 56 (12.2%) horses, whereas on 8 (44.4%) farms at least one horse was found to be infected. The lowest and the highest within farm prevalence was 4.3% and 70%, respectively. Males and Arabian purebred horses had significantly higher infection rates than females and the other breeds, respectively. Differences in prevalence in relation to age -animals between 1 and 3 years of age being more affected than older and younger ones- are seen.Publication Studies on sheep lungworms in Bursa Province of Turkey: Determination of prevalence and relationships between larval output and parasite burden in the lungs(Zoological Soc Pakistan, 2008-01-01) Girişgin, Oya; ŞENLİK, BAYRAM; GİRİŞGİN, OYA; GİRİŞGİN, AHMET ONUR; Girisgin, Ahmet Onur; Akyol, Volkan; AKYOL, ÇETİN VOLKAN; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Parasitoloji Anabilim Dalı.; 0000-0003-2964-2245; 0000-0002-0020-2708; B-5286-2017; JRY-1676-2023This study was carried out to determine lungworm species and their prevalence, evaluate the effect of host age and breed oil the infections and the correlation between faecal larvae counts and adult lung worms counts in sheep in Bursa Province, Turkey. A total of 104 sheep of different age and breed were examined for the lungworm infection. prevalence of infection was 45.1% and 62.5% by coproscopy and necropsy, respectively. The faecal examination and postmortem showed Dictyocaulus filaria (23%; 31.7%), Cystyocaulus ocreatus (24%; 31.7%) and Protostrongylus rufescens (3.8%; 5.8%). Seven (6.7%) and six (5.7%) sheep had mixed infections with two nematode species in necropsy and faecal examinations, respectively. There was a significant difference (p<0.05) between >4 year old and <4 year old age groups. There was no significant difference in the prevalence of lungworm infections in different sheep breeds. Although there was a positive correlation between larval excretion in faeces and lung nematode counts, reliable regression equations could not be established. Therefore, the number of worms in the lungs Could not be deducted exactly from faecal lungworm larvae counts.
