Because of their distribution in urbanised regions, magpies may have some potential infectious agents which may relate to domestic animals and humans. In this study, eight common magpies brought to the animal hospital in need of medical intervention were examined for endoparasites and bacteria in a one-year period. Additionally, histopathologic examinations with related organs were carried out along with endo-parasitical, cytological and microbial examination the following necropsy. As results of the necropsies, three parasite species including two helminths and one protozoan (Passerilepis sp., Brachylaima sp., Isospora rochalimai, respectively) were identified, while Staphylococcus xylosus, S. sciuri, Escherichia coli, Klebsiella pneumonia, Salmonella spp. were isolated after microbiological examination. Histopathology revealed that subacute focal mycotic pneumonia, chronic nonpurulent granulomatous gastroenteritis, verminous enteritis, and the presence of paratyphoid nodules in liver. Both of the parasites and bacteria are the first records for Turkey's helminth/bacterial fauna in wild birds.Publication First molecular detection of Nosema ceranae in Azerbaijan(Taylor & Francis, 2019-05-30) Utuk, Arnnağan Erdem; Aliyeva, Rafiga; Girişgin, Ahmet Onur; Gökmen, Tülin Güven; Özüiçli, Mehmet; Aydın, Levent; GİRİŞGİN, AHMET ONUR; ÖZÜİÇLİ, MEHMET; AYDIN, LEVENT; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı.; 0000-0002-0020-2708; B-5286-2017; HLG-4450-2023Nosemosis is an important adult honey bee disease and causes economic losses worldwide. The aim of this study was to determine the Nosema species in honey bees (Apis mellifera) of Azerbaijan. For this aim, honey bee samples were collected from the Central (Ganja), Northern (Qakh) and Southern (Astara) parts of the country. Samples were examined microscopically, and 10 out of 24 samples (41.6%) were found to be positive for Nosema sp. spores. Positive samples were tested with a multiplex-PCR for the detection of Nosema species. As a result of our study, we could not detect N. apis but we determined the N. ceranae for the first time in Azerbaijan.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 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 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 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 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 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.
