Dartmouth Scholarship
Middle East respiratory syndrome coronavirus (MERS-CoV) emerged in 2012. Recently, the MERS-CoV receptor dipeptidyl peptidase 4 (DPP4) was identified and the specific interaction of the receptor-binding domain (RBD) of MERS-CoV spike protein and DPP4 was determined by crystallography. Animal studies identified rhesus macaques but not hamsters, ferrets, or mice to be susceptible for MERS-CoV. Here, we investigated the role of DPP4 in this observed species tropism. Cell lines of human and nonhuman primate origin were permissive of MERS-CoV, whereas hamster, ferret, or mouse cell lines were not, despite the presence of DPP4. Expression of human DPP4 in nonsusceptible BHK and …

The aim of the present study was to compare the effectiveness of cefuroxime, herd-specific autovaccine, and cefuroxime/herd-specific autovaccine treatments in eliminating S. aureus from the milk of 45 cows with subclinical mastitis. Prior to this study, cows with S. aureus mastitis were divided into 3 groups of 15 cows each. Group 1 received cefuroxime, group 2 received the autovaccine, and group 3 received cefuroxime and the autovaccine. The antibiotic was infused into the teat canal, whereas the autovaccine was administrated in the upper udder lymph node region. It was revealed that after day 35 of the treatment S. aureus was …

The aim of this study was to determine the possibility of yielding more transferable embryos from cows superovulated with/without exogenous progesterone (ear implant and intravaginal device). Two experiments were conducted in Holstein Friesian cows to evaluate the effect of exogenous progesterone on the yield of corpus luteum (CL), total embryo and ova, and transferable embryos before superovulation. A superovulation program using 2 different progesterone resources was applied (G1 = intravaginal device, G2 = ear implant). Superovulation and uterus irrigations were done at 28-day intervals in the treatment groups. Cows in the control group were superovulated at 60-day intervals without application …

Both cattle and dogs were examined in modern and rural dairy farms that had a history of abortion over 5%. The blood samples were collected from 427 aborted cattle and the sera were tested using a commercial ELISA test kit. Additionally, a necropsy procedure was carried out on the fetuses and calves dead within 2 months after birth; the tissue samples were evaluated by histopathologic, immunoperoxidase, and PCR techniques. Eighteen dogs in close contact with the cattle in the same field were included in the study and blood and feces samples were collected. The feces samples were analyzed by copro-PCR …
Insertion/Deletion Polymorphism Of The Sterol Regulatory Element-Binding Protein 1 Gene In Different Cattle Breeds, Witold Stanislaw Proskura
Insertion/Deletion Polymorphism Of The Sterol Regulatory Element-Binding Protein 1 Gene In Different Cattle Breeds, Witold Stanislaw Proskura
Turkish Journal of Veterinary & Animal Sciences
In the present study, an 84-bp insertion/deletion polymorphism of the sterol regulatory element-binding protein 1 (SREBP1) gene was investigated. The analysis included 6 Polish cattle herds consisting of beef (Limousin, Angus, Charolais), dairy (Holstein-Friesian, Jersey) and dual-purpose (Montbeliard) breeds. The polymorphism was found only in Limousin and Montbeliard animals, in which both the short (S)- and long (L)-type alleles occurred. The genotype distribution in Montbeliard cattle was as follows: 0.038, 0.406, and 0.556 for SS, LS, and LL, respectively. To the author's knowledge, this study was the first to investigate the above-mentioned polymorphic site in the Montbeliard and Jersey cattle …

This study was conducted to determine the relationship between the degrees of anemia and blood gases in cattle with theileriosis. It included 28 cattle with theileriosis and 7 healthy animals as the control group. The cattle with theileriosis were divided into 4 groups according to their hematocrit (Hct) values: cattle with Hct of >26 were considered as nonanemic (Group 1), Hct of 20-26 as mildly anemic (Group 2), Hct of 14-19 as moderately anemic (Group 3), and Hct of 10-13 as severely anemic (Group 4). The PCO_2, HCO_3, and TCO_2 levels in the study groups were lower than those of …

Bovine cytochrome P450 3A28 is responsible for metabolizing ergot alkaloids that cattle ingest when feeding on endophyte-infested tall fescue grass. The objective of this research was to determine associations among genotype, transportation, and stress responses. Angus crossbred steers (n = 47) were genotyped (CC, CG, or GG) for a single-nucleotide polymorphism (C994G) in cytochrome P450 3A28. Genotypes were determined by polymerase chain reaction (PCR) amplification followed by restriction enzyme (Alu1) digestion. Steers were backgrounded on a mixedcultivar tall fescue pasture. Following the stocker phase, steers were transported to the feedlot for finishing. Stress responses were determined 27 h prior to, …

Recent progress in genomic analysis and other biochemical methods has led to the discovery of a large population of microRNAs (miRNAs), which have been demonstrated to play important roles in diseases and a wide range of developmental processes. Characterization of miRNA expression profiles in different stages of ovarian follicular development and early embryogenesis has suggested the potential roles of miRNAs in follicular development, maturation of oocytes, and preimplantation embryonic development. This review focuses on the current studies of miRNAs involved in ovarian and early embryonic development in cattle.
