Molecular Identification Of Bovine Papillomaviruses In Dairy And Beef Cattle: First Description Of Xi- And Epsilonpapillomavirus In Turkey, Veysel Soydal Ataseven, Özgür Kanat, Yaşar Ergün

Turkish Journal of Veterinary & Animal Sciences

In the current study, 23 papilloma/tumor-like samples obtained from cattle having clinical lesions and 9 blood samples collected from healthy-appearing cattle in Turkey were examined for bovine papillomavirus (BPV) DNA using the degenerate primers FAP59/64, and the different types of BPV were distinguished by type-specific primer sets. Furthermore, histopathological studies of papillomavirus were performed. A total of 7 BPV types (BPVs 1, 2, 3, 4, 6, 8, 9), including genera Deltapapillomavirus, Xipapillomavirus, and Epsilonpapillomavirus, were identified. In all samples, BPV-1 was the most common genotype (90.6%). Overall, coinfections were determined in 26 of the examined samples (81.3%), and coinfection with …

Cla And Epa Inhibit Lps-Induced Prostaglandin Release From Bovine Endometrial Cells Through An Nf-?B-Dependent Signaling Mechanism, Lokenga Badinga, Mehmet Şükrü Gülay, Alan Ealy

Turkish Journal of Veterinary & Animal Sciences

Although their action in antagonizing arachidonic acid metabolism is a key antiinflammatory effect of conjugated linoleic acid (CLA) and omega-3 polyunsaturated fatty acids (n-3 PUFA), these molecules have other antiinflammatory effects that might occur upstream of altered eicosanoid production. We examined the effects of two CLA isomers (c9,t11 and t10,c12 isomers), n-3 PUFA (EPA and DHA), and ΚNF-ΚB inhibitor (ammonium pyrrolidine dithiocarbamate (PDTC)) on lipopolysaccharide (LPS)-induced secretion of prostaglandins (PGE2 and PGF2a) by bovine endometrial (BEND) cells. LPS increased PGE2 and PGF2a concentrations in BEND cell-conditioned media in a concentration- and time-dependent manner. The c9,t11 CLA isomer and EPA decreased …

Mast Cell Typing In Aortic Onchocerciasis And The Immunohistochemicaldemonstration Of Wolbachia Bacteria, Rahşan Yilmaz, Melek Koçak, Zafer Özyildiz, İsmai̇l Şah Harem

Turkish Journal of Veterinary & Animal Sciences

In this study, the presence of endosymbiotic Wolbachia bacteria was determined by immunohistochemical methods in 8 out of 43 paraffin-embedded bovine aortic tissues that were macroscopically and microscopically diagnosed with aortic onchocerciasis in the archive of the Harran University Faculty of Veterinary Medicine's Department of Pathology. By means of the enzyme histochemical and immunohistochemical staining methods, it was ascertained that the tryptase-containing subtype of mast cells (MCT) was involved in the inflammatory response in the bovine aortae with onchocerciasis. The aim of this study was to elucidate the pathogenesis of aortic onchocerciasis lesions caused by Onchocerca armillata in Turkey and …

Mycoplasma Infections In Dairy Cattle Farms In Turkey, Zafer Sayin, Asli Sakmanoğlu, Uçkun Sai̇t Uçan, Ali̇ Uslu, Hasan Hüseyi̇n Hadi̇mli̇, Zeki̇ Aras, Özgür Özdemi̇r, Osman Ergani̇ş

Turkish Journal of Veterinary & Animal Sciences

Mycoplasmas cause the most severe and economically costly diseases of cattle throughout the world. In this study, Mycoplasma species were isolated from calves and cows with suspected mycoplasmosis in Holstein dairy cattle farms within 7 geographical regions of Turkey between May 2010 and December 2015. Mycoplasma infections were positive in 17 (80.9%) of 21 dairy cattle farms and the overall percentage was calculated as 32.1%. The highest isolation rate occurred in the Southeastern Anatolia Region (42.8%), and the lowest was observed in the Mediterranean Region (19.6%). In total, 172 Mycoplasma spp. were isolated from samples. Using PCR analysis, 149 (87.6%) …

Effects Of Growing-Season Prescribed Burning On Vigor Of The Noxious Weed Sericea Lespedeza (Lespedeza Cuneata) In The Kansas Flint Hills, J. A. Alexander, W. H. Fick, J. Lemmon, C. A. Gurule, G. W. Preedy, K C. Olson

Kansas Agricultural Experiment Station Research Reports

Sericea lespedeza (SL) was introduced into the United States from Asia in the late 19th century. Early land managers recognized that SL was adaptable; tolerant of shallow, acidic or low-fertility soils; and resistant to insects and disease. This combination of traits made SL a widely-used plant for reseeding strip-mined lands, highway right-ofways, dams, and waterways in the US for nearly a century.

Regrettably, SL is highly fecund. Individual plants are capable of producing up to 850 lb of seed per acre annually. Vigorous seed production allows SL to rapidly infiltrate native grasslands that are adjacent to reseeding projects; seed can …

Comparison Of Hematological Parameters Of Brucella-Seronegative Naturallyinfected Cattle With Bvdv, Bhv-1, And Bhv-4, Muhammet Eren Aslan, Ahmet Kürşat Azkur, Emel Biyikli, Serkal Gazyağci, İbrahi̇m Sözdutmaz

Turkish Journal of Veterinary & Animal Sciences

Abortion, neonatal deaths, and infertility cause important production losses in the livestock industry. Many viral infections are responsible for changes in hematological values of animals. This study aimed to find whether there is any difference in blood parameters of cattle that are naturally infected with BVDV, BHV-1, and BHV-4 and Brucella-seronegative. For this purpose, 401 whole-blood samples collected from cattle were analyzed by ELISA and PCR/RT-PCR to detect specific antibodies and antigens for BVDV, BHV-1, and BHV-4. Hematological analysis and results were compared between naturally infected BVDV, BHV-1, and BHV-4 groups and a control group. Results showed a statistically significant …

The Effect Of Dgat1 Polymorphism On Milk Production Traits In Dairycows Depending On Environmental Temperature, Jolanta Komisarek, Mateusz Kolenda

Turkish Journal of Veterinary & Animal Sciences

It has long been known that a hot environment negatively influences milk production in cattle. Although molecular mechanisms underlying this phenomenon to a great extent remain to be recognized, they include alterations in lipid metabolism. DGAT1 plays a key role in the synthesis of triacylglycerols and polymorphism of this gene has been proven to have a pronounced influence on milk production. The aim of this study was to establish if the effect of DGAT1:p.K232A on milk-related traits is dependent on environmental thermal conditions. The analysis, performed on 468 cows of the Polish Holstein-Friesian breed, showed that allele DGAT1:K232 significantly increased …
