Crimean-Congo Hemorrhagic Fever Virus Infection in Domestic Ruminants in Van Province, a Non-Endemic Region in Turkey
(Agricultural Research Communication Centre, 2023) Babaoglu, A. R.; Oguz, F. Ertas; Kilinc, O. Orunc; Cetin, N.; Aslan, L.
Background: Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne viral disease of humans that is most widespread in Africa, Asia, the Middle East and Southeast Europe. The disease has continued to be a health problem in Turkey and other endemic countries in recent years. CCHF virus does not cause clinical disease in animal hosts but develops an antibody response and a transient viraemia. The aim of this study is to evaluate the status of CCHF infection serologically and virologically in livestock in the Van region, a non-endemic area in Turkey. Methods: A total of 491 whole blood and 491 serum specimens were collected from cattle, sheep and goats in different locations of Van province in Turkey from May 2020 to October 2021. To determine the CCHFV-specific antibody, all sera from animals were tested with a double-Ag ELISA-Ab kit. An RT-PCR assay was performed on total leucocyte samples for the virological study to detect the presence of European lineage-1 CCHFV nucleic acids and viraemic animals. Result: The prevalence of CCHFV-specific antibodies in animals was found to be 36.4%. The seroprevalence values detected were 11.6%, 64.45% and 81.63% in cattle, sheep and goats, respectively. In the RT-PCR assay, 1.22% (6/491) of the tested animals were found to be viraemic at the time of sampling.
Effect of Management System and Dietary Yeast Autolysate on the Performance, Slaughter and Carcass Characteristics of Partridges (Alectoris Chukar)
(South African Journal of Animal Sciences, 2018) Bolacali, M.; Kucuk, M.; Tufan, T.; Aslan, L.
This study was conducted to determine the effects of management system (a floor housing (FH) versus a free-range housing (FRH) system) and dietary yeast autolysate (Saccharomyces cerevisiae) (1% versus 2% dietary supplement) on the performance, slaughter and carcass characteristics of partridges (Alectoris chukar). A total of 480 (240 for each management system) one-day-old male partridge chicks were randomly allocated to a control group and the two dietary groups per production system, each containing 80 chicks. Each dietary group was then divided into five replicate groups of 16 chicks. The study lasted 112 days. In terms of growth performance, partridges reared under FRH management system had a lower average daily live weight gain (ADG), a significantly higher feed intake (FI), and feed conversion ratio (FCR) compared to the control group. However, partridges fed diets with yeast autolysate had a significantly higher ADG, lower FI, and an improved FCR compared to the control group overall. The gizzard, leg, and wing percentages of the partridges reared in the FRH system were found to be significantly higher than those of partridges reared in the FH system, while the breast and abdominal fat percentages were found to be lower. Dietary supplementation with yeast autolysate significantly increased the cold carcass yield and breast percentage when compared to the control group, while wing and abdominal fat percentages were decreased. In general, best performance was observed in the dietary supplementation group of 1% yeast autolysate in terms of growth and carcass parameters. When considering the fact that partridges are gamebirds, that housing poultry in cage production systems has been prohibited in recent years and that there are positive effects associated with using yeast autolysate as a prebiotic, it is recommended that a free-range production system should be used for partridge breeding, with the addition of 1% yeast autolysate to the diet of the birds.
Effects of Green Tea on Mineral Levels of Liver and Testis of Guinea Pigs Electromagnetic Field Emitted by Mobil Phones
(2009) Kiliçalp, D.; Dede, S.; Deger, Y.; Aslan, L.
It was reported that the effects of green tea on the mineral levels of testis and liver of Guinea pigs exposed to a 900 MHz electromagnetic field. Four experimental groups labeled as controls (Group A), irradiated (Group B), irradiated receiving green tea extract (Group C) and green tea only (Group D) were formed with seven randomly chosen animals of both sexes in each group. After exposure for one month, the animals were sacrificed by decapitation and testis and liver samples were collected for biochemical analysis. In female Guinea pigs irradiation with and without green tea as well as green tea alone caused significant changes of the iron levels in liver, but no significant changes of manganese, copper, zinc and the copper/zinc ratio. In males, irradiation caused significant increases of manganese and a decrease of the iron levels in liver and of manganese, copper, zinc in testis. Combined with green tea, electromagnetic radiation resulted in changes of manganese, iron, copper and copper/zinc ratio in liver and of manganese only in testis. Green tea alone changed the levels of hepatic iron, zinc and copper/zinc ratio and of testicular concentrations of iron and zinc. The highest levels of copper were found in the liver tissue of the irradiated animals that were also treated with green tea. From present findings we can state that testis tissue is more sensitive to electromagnetic radiation than liver tissue, showing greater changes in trace mineral metabolism. Green tea brings the trace element levels to near normal values; supporting the idea that green tea as a supplement has a protective effect against the damaging effects of electromagnetic radiation. © 2009 Academic Journals Inc.
Evaluation of the Anesthetic Effects of Xylazine-Ketamine, Xylazine-Tiletamine and Tiletamine-Zolazepam Using Clinical and Laboratory Parameters in Rabbits
(Polskie Towarzystwo Nauk Weterynaryjnych, 2018) Karasu, A.; Altug, N.; Aslan, L.; Bakir, B.; Yuksek, N.
The aim of this study was to evaluate the anesthetic effects of xylazine-ketamine (XK), xylazine-tiletamine-zolazepam (XTZ) and tiletamine-zolazepam (TZ) using hematological and biochemical parameters in rabbits. ' A total of 18 rabbits were divided into three equal treatment groups (n = 6). The rabbits in the XK, XTZ, and TZ groups were administered xylazine (5 mg/kg) and ketamine (50 mg/kg), xylazine (5 mg/kg) and TZ ; (15 mg/kg), and TZ (15 mg/kg), respectively, via the intramuscular route. Following the injection, their reflexes ; were tested every 5 minutes. Heart rate, respiratory rate, and body temperature were determined before ; the injection (0 min) and at 5, 15, 30, 45, 60, 75, 90, and 120 min after injecting the anesthetic combinations. Furthermore, hematological and biochemical (alanine transaminase [ALT], aspartate transaminase [AST], alkaline phosphatase [ALP], bilirubin, blood urea nitrogen [BUN], and urea) analyses were also performed before, during, and after anesthesia administration. The duration of anesthesia and loss of reflexes were significantly longer in the XTZ group than in the other groups. However, in the TZ group, reflexes were remained. Respiratory rate and body temperature decreased in all the groups. Moreover, heart rate reduced only in the XK and XTZ groups, and the hematological parameters of all groups were comparable. Serum AST and ALP levels increased in the XTZ group compared to that in the XK and TZ groups, respectively. However, these increases were within the reference limits. The post-anesthesia serum BUN and urea levels significantly increased in the XTZ group (p < 0.05) compared to that in the other groups. Thus, although the XTZ combination provided satisfactory anesthetic effect in rabbits, it may be nephrotoxic. Therefore, its use for anesthesia induction in invasive renal procedures and experimental nephrotoxicity studies is not advisable. © 2018 Polskie Towarzystwo Nauk Weterynaryjnych.

Management of the Feral European Rabbit, Oryctolagus Cuniculus, on Akdamar Island, Lake Van, Türkiye
(Taylor and Francis Ltd., 2025) Aslan, L.; Turan, Ş.; Per, E.; Cırık, Ö.; Coşkun, G.
Lake Van is Türkiye’s largest lake, and within it lies Akdamar, a small seven-hectare island. In 2008, eight feral European rabbits were introduced to the island to attract tourists. With no natural predators, their population had increased to 3,000 by 2016, causing severe ecological damage, destroying almond trees, accelerating soil erosion, and damaging historical buildings through burrowing. In response, local authorities launched a management programme from 2016 to 2017, removing 1,500 rabbits through physical control methods such as live trapping, net trapping, and night spotlighting. However, funding shortages halted further efforts, and the population surged to an estimated 4,000–5,000 by 2023. The rabbits now occupy the entire island, degrading vegetation, diminishing ecosystem services, and threatening tourism. According to the assessment conducted in this study, the situation is classified as causing major ecological impacts under the Environmental Impact Classification for Alien Taxa and minor cultural effects under the Socio-Economic Impact Classification of Alien Taxa. Therefore, urgent, long-term management solutions are essential to prevent further degradation, with public awareness campaigns, community involvement, and education can help reduce human-mediated spread and promote responsible behaviour. Coupled with sustainable, effective management strategies, these efforts are vital to preserving the island’s ecosystem and cultural heritage. © 2025 Informa UK Limited, trading as Taylor & Francis Group.
