Varroacidal Efficacies Of Essential Oils Extracted From Lavandula Officinalis, Foeniculum Vulgare, And Laurus Nobilis In Naturally Infested Honeybee (Apis Mellifera L.) Colonies, Fi̇gen Kütükoğlu, Ahmet Onur Gi̇ri̇şgi̇n, Levent Aydin

Turkish Journal of Veterinary & Animal Sciences

This study was performed to determine the efficacies of Lavandula officinalis, Foeniculum vulgare, and Laurus nobilis essential oils on the control of Varroa destructor (Acari: Varroidae), the most common parasite of honeybees (Apis mellifera L.). Experimental colonies from the province of Bursa, Turkey, were divided into 5 homogeneous groups of 8 hives each. The 3 essential oils plus thymol (Thymovar®, an essential oil-based drug with known efficacy that was used for comparison) were applied to 1 group each and 1 group was left untreated as a control. Each group was treated during 3 seasons, 2 consecutive autumns and 1 spring. …


Efficacies Of Fenbendazole And Albendazole In The Treatment Of Commercial Turkeys Artificially Infected With Ascaridia Dissimilis, Jessica Perkins, Tom Yazwinski, Chris Tucker Jan 2012

Efficacies Of Fenbendazole And Albendazole In The Treatment Of Commercial Turkeys Artificially Infected With Ascaridia Dissimilis, Jessica Perkins, Tom Yazwinski, Chris Tucker

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

The goal of this research was to determine the extent of resistance that turkey roundworms, Ascaridia dissimilis, have developed to anti-parasitic chemicals used in commercial poultry operations. Roundworm infections in turkeys have resulted in monetary losses for the poultry industry for years, generally due to poor feed conversion. The infection itself is subclinical and many turkeys have a light to moderate worm burden. Since parasitisms are light, this leads to the infections being noticed only during processing. Ascaridia dissimilis infections consist of adult worms and developing larvae with the latter comprising most of the worm burden and causing the most …

Turkish Journal of Veterinary & Animal Sciences

The aim of this study was to identify ectoparasites of wild roe deer (Capreolus capreolus) living in natural areas of Samsun Province that were wounded by car accidents or hunters between 2007 and 2010. A total of 90 ticks, 60 lice, and 5 deer keds were collected from 17 animals. Five tick species (Ixodes ricinus, Rhipicephalus bursa, Rhipicephalus turanicus, Haemaphysalis punctata, and Haemaphysalis concinna), 1 louse species (Cervicola meyeri), and 1 deer ked species (Lipoptena cervi) were identified. Cervicola meyeri and L. cervi were identified for the first time in Turkey.


Purification And Characterization Of Glutathione Reductase From Turkey Liver, Pinar Taşer, Mehmet Çi̇ftci̇ Jan 2012

Purification And Characterization Of Glutathione Reductase From Turkey Liver, Pinar Taşer, Mehmet Çi̇ftci̇

Turkish Journal of Veterinary & Animal Sciences

This study aimed to purify glutathione reductase (GR) from turkey liver and investigate some of its characteristic features. The purification procedure comprised 2 steps: homogenate preparation and 2',5'-ADP Sepharose 4B affinity gel chromatography. Thanks to the 2 consecutive procedures, the enzyme, having the specific activity of 606.67 EU mg protein^{-1}, was purified with a yield of 10.75% and 2476-fold, and, in order to control enzyme purity, SDS-PAGE was done. Optimal pH, stable pH, optimal temperature, optimal ionic strength, molecular weight, turnover number of enzyme, and k_{cat}/K_M and K_M and V_{max} values for NADPH and glutathione disulfide substrates were also determined …
