Publication Description of lens atrophy caused by Shewanella sp. strain S-1, a putative novel species isolated from cultured rainbow trout(Elsevier, 2021-04-13) Satıcıoğlu, İzzet Burçin; İsbilir, Fatma; Yavaş, Özkan; Avcı, Zehra; Özdemir, Burak; Süzer, Bayram; Altun, Soner; Duman, Muhammed; İŞBİLİR, FATMA; YAVAŞ, ÖZKAN; Avcı, Zehra; SÜZER, BAYRAM; ALTUN, SONER; DUMAN, MUHAMMED; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Anatomi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Patoloji Anabilim Dalı.; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Su Hayvanları Hastalıkları Anabilim Dalı.; 0000-0002-2687-1221; 0000-0001-7707-2705; 0000-0001-9096-875X; HJI-5667-2023; KHD-4075-2024; X-2000-2019; GLV-3407-2022; T-1697-2019; EZZ-5951-2022; CCJ-5608-2022; AAG-8518-2021In the present study, we describe a pathogenic incidence of Shewanella sp. S-1 infection in cultured rainbow trout (Oncorhynchus mykiss, Walbaum, 1792), as evidenced by lens atrophy, inappetence, visual impairment, and growth retardation. Strain S-1 was identified using basic microbiological tests, the BD PhoenixTM rapid diagnostic kit, the MALDI-TOF MS system, and whole-genome analysis. This strain's pathogenicity was assessed based on the histopathological examination of the eyes, lens, muscle, brain, liver, kidney, spleen, and gills. The lens, brain, and eyes of the fish were also examined morphologically. According to genome-based delineation, strain S-1 was determined to belong to the genus Shewanella and was considered a putative novel Shewanella species. While we determined that the lens had atrophied at a level ranging from 30% to 40%, no severe lesion was detected in other organs. Fish that hatched in the same period were bred under uniform feeding and management conditions for a month. Monitoring data revealed that, at the end of this 1-month period, the growth rate and feed conversion rate of the diseased fish were significantly lower than those of the healthy group. Based on microbiological and pathological findings, we concluded that Shewanella sp. S-1 caused lens atrophy in the rainbow trout.Publication Effects of genotype and housing system on some bone biomechanical characteristics in broiler chickens(Ankara Üniversitesi, 2019-04-21) Süzer, Bayram; Tüfekci, Kenan; Arıcan, İlker; Petek, Metin; Abdourhamane, Ibrahima Mahamane; Özbek, Melahat; Yıldız, Hüseyin; SÜZER, BAYRAM; TÜFEKCİ, KENAN; ARICAN, İLKER; PETEK, METİN; Abdourhamane, Ibrahima Mahamane; Özbek, Melahat; YILDIZ, HÜSEYİN; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Anatomi Anabilim Dalı.; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Makina Mühendisliği Bölümü.; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Zootekni Bölümü.; 0000-0002-2687-1221; 0000-0001-5358-1396; 0000-0001-6342-0094; 0000-0001-8789-3101; AAG-7076-2021; AAA-1366-2021; X-2000-2019; AAG-7518-2021; DNZ-6767-2022; EKQ-7243-2022; FNV-0028-2022The aim of this study was to determine the effects of two genotypes (slow-growing and fast-growing) and three housing systems (deep litter, plastic slat and free-range) on some bone biomechanical properties of broiler chickens and to evaluate the interaction between genotype and housing systems. Broilers from two genotypes were reared at three different housing conditions. Fifteen bones were randomly selected from each housing system in both slow-growing and fast-growing groups, and the experiment was performed on 90 bones in total. To determine bone characteristic and biomechanical traits of tibiotarsi, bones collected from right leg and then weighed, cortical area measurements and three-point bending tests were applied. Both live body weight and carcass weight were significantly affected by genotype and housing systems. There was no interaction between genotype and housing system in terms of bone weight, cortical area, breaking strength, bending strength, and deflection. Also, housing systems had no statistical effect on these parameters. Fast-growing broilers were significantly had heavier tibiotarsi, larger cortical area and higher breaking strength than slow-growing broilers, while bending strength was significantly lower in fast-growing broilers. Deflection was not affected by genotype or by housing system. In conclusion, bone geometry and biomechanical properties were not affected by housing systems but by genotype. Fast-growing broilers had better bone morphology and stronger bones than slow-growing genotype. Therefore, fast-growing genotype can provide positive effects on bone growth and mechanical properties in broilers.Publication The relationship between spirulina platensis and selected biomechanical indicators of tibiae in rats(Czech Academy Agricultural Sciences, 2020-01-01) Süzer, Bayram; Seyidoğlu, Nilay; Tüfekçi, Kenan; İnan, Sevda; SÜZER, BAYRAM; TÜFEKCİ, KENAN; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Anatomi Anabilim Dalı; Bursa Uludağ Üniversite/Mühendislik-Mimarlık Fakültesi,/Makine Mühendisliği Bölümü; 0000-0002-2687-1221; 0000-0001-5358-1396; AAG-7076-2021; GLV-3407-2022There are several dietary supplements, particularly herbal foods, that have been used in an attempt to improve bone growth. In this study, we aim at determining the effects of low- and high-doses of Spirulina platensis, a "Superfood", on the bone growth and biomechanical indicators. Thirty Wistar rats, weighing 250 g, at the age of 7-8 weeks were assigned to three groups: The Control group (basal diet), Low-dose group (LDG; 500 mg/kg) and High-dose group (HDG; 1 000 mg/kg) of S. platensis. S. platensis was given daily by oral gavage in a 45-day-trial. At the end of the study, the right tibiae were collected and subjected to bone biomechanical tests (bone weight, bone length, maximum load, stiffness, breaking deflection, fracture toughness, post-yield displacement and yield load). Serum samples were also analysed for the calcium and phosphorus concentrations. There were significant increases in bone weight, bone length, maximum load, breaking deflection, work to fracture, post-yield displacement and yield load (P = 0.025, P = 0.019, P = 0.030, P = 0.015, P = 0.031, P = 0.028, P = 0.049, respectively), whereas stiffness non-significantly increased. However, there were no significant differences (P > 0.05) for any variables between the LDG and the HDG. Although the serum phosphorus concentrations showed no differences among any of the groups, the serum calcium concentration increased significantly in LDG compared to Control group (P = 0.009; 7.14 +/- 0.47 and 9.45 +/- 0.67, respectively). However, no differences were observed in HDG in terms of serum calcium. In conclusion, S. platensis had positive effects on the bone growth and biomechanical bone features. Therefore, our study supports the use of S. platensis as an alternative food additive for bone growth and health in growing animals.Publication Comparison of some biomechanical properties of tibiotarsus in four different feather color lines of 60-day old female quails(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2020-01-01) Süzer, Bayram; SÜZER, BAYRAM; Petek, Metin; PETEK, METİN; Tüfekçi, Kenan; TÜFEKCİ, KENAN; Arıcan, İlker; ARICAN, İLKER; Abdourhamane, Ibrahima Mahamane; Yıldız, Hüsnü; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi; Bursa Uludağ Üniversitesi/Veteriner Fakültesi/Anatomi Anabilim Dalı.; 0000-0002-2687-1221; 0000-0001-5358-1396; 0000-0001-6342-0094; 0000-0001-8789-3101; 0000-0003-2091-0303; GLV-3407-2022; AAG-7076-2021This study aimed to compare some morphological and mechanical measurements of four different color female quails to contribute to the formation of the morphological database.Quails are the smallest farmed avian species which are becoming more important for the poultry industry. They are also used as experimental animals and are valuable birds for researches. Genetic factors are important determinants of bone strength. Thus, skeletal disorders may be reduced by breeding selection in quails. Forty female quails with four different feather colors, including wild, white, yellow, and black, were compared at 60 days of age. Each quail group contained ten individuals. A three-point bending test was performed with a custom-made testing machine designed for low strength materials. No significant difference was found between the groups in terms of body weight. The tibiotarsus weight in wild and black (0,665 +/- 0,055g and 0,687 +/- 0,025g, respectively) was significantly lower than in the others but, the significant highest value was in white quails (0,758 +/- 0,063g) (p=0.001). Significantly shorter tibiotarsus was observed in the black quails (51,286 +/- 1,374mm), while the tibiotarsi of the white and yellow quails were the tallest (53,216 +/- 1,796mm and 53,083 +/- 1,092mm, respectively) (p=0.005). There were no significant differences among the groups in the biomechanical properties of tibiotarsus, except stiffness. Stiffness was the highest in the white quails (109,500 +/- 3,807 N/mm) and the lowest in the black quails (99,000 +/- 9,498 N/mm) (p=0.042). In conclusion, white quails have been observed to have relatively better bone biomechanical properties compared to the other color groups at 60 days of age.Publication Practices for drawing blood samples from teleost fish: Response to comment(Wiley, 2019-09-06) Duman, Muhammed; Satıcıoğlu, İzzet B.; Süzer, Bayram; Altun, Soner; DUMAN, MUHAMMED; SÜZER, BAYRAM; ALTUN, SONER; Uludağ Üniversitesi/Veteriner Fakültesi/Su Hayvanları Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Anatomi Anabilim Dalı.; 0000-0001-7707-2705; 0000-0002-2687-1221; AAG-8518-2021; T-1697-2019; GLV-3407-2022
