Inspection Of C-Type Lectin Superfamily Expression Profile In Chicken And Mouse Dendritic Cells, Kaj Chokeshaiusaha, Roongroje Thanawongnuwech, Denis Puthier, Catherine Nguyen

The Thai Journal of Veterinary Medicine

C-type lectin superfamily is a cell surface molecule family well-recognized for its role in inducing and tailoring dendritic cell (DC) immune response. Despite its importance in DC targeting and activation, knowledge about C-type lectin family expression in chicken DC is still limited, and thus hinders its utilization for poultry DC vaccine development. In this study, expressions of C-type lectin orthologous gene among available chicken and mouse DC subsets were determined for expression levels and differential expression patterns. Leukocyte microarray datasets and bone marrow-derived DC mRAN-sequencing datasets were pre-processed prior to observation and comparison. Data virtualization revealed variation in C-type lectin …

Neutering Of German Shepherd Dogs: Associated Joint Disorders, Cancers And Urinary Incontinence, Benjamin L. Hart, Lynette A. Hart, Abigail P. Thigpen, Neil H. Willits

Endocrinology Collection

German Shepherd Dogs are important in police and military work, and are a popular family pet. The debilitating joint disorders of hip dysplasia, cranial cruciate ligament tear (CCL) and elbow dysplasia can shorten a dog’s useful working life and impact its role as a family member. For this study, veterinary hospital records were examined over a 14.5-year period on 1170 intact and neutered (including spaying) German Shepherd Dogs for joint disorders and cancers previously associated with neutering. The diseases were followed through 8 years of age, with the exception of mammary cancer (MC) in females that was followed through 11 …

Insulin-Dependent Glucose Metabolism In Dairy Cows With Variable Fat Mobilization Around Calving, C. Weber, C. T. Schäff, U. Kautzsch, S. Börner, S. Erdmann, S. Görs, M. Röntgen, H. Sauerwein, R. M. Bruckmaier, C. C. Metges, B. Kuhla, H. M. Hammon

Physiology Collection

Dairy cows undergo significant metabolic and endocrine changes during the transition from pregnancy to lactation, and impaired insulin action influences nutrient partitioning toward the fetus and the mammary gland. Because impaired insulin action during transition is thought to be related to elevated body condition and body fat mobilization, we hypothesized that over-conditioned cows with excessive body fat mobilization around calving may have impaired insulin metabolism compared with cows with low fat mobilization. Nineteen dairy cows were grouped according to their average concentration of total liver fat (LFC) after calving in low [LLFC; LFC <24% total fat/dry matter (DM); n = 9] and high (HLFC; LFC >24.4% total fat/DM; n = 10) fat-mobilizing …

A Cluster Of Trace-Concentration Methamphetamine Identifications In Racehorses Associated With A Methamphetamine-Contaminated Horse Trailer: A Report And Analysis, Kimberly Brewer, Theodore F. Shults, Jacob Machin, Sucheta Kudrimoti, Rodney L. Eisenberg, Petra Hartman, Caroline Wang, Clara Fenger, Pierre Beaumier, Thomas Tobin

Three low concentration methamphetamine “positive” tests were linked to use of a methamphetamine-contaminated trailer to transport the affected horses. This incident establishes methamphetamine as a human-use substance that can inadvertently enter the environment of racing horses, resulting in urinary methamphetamine “positives;” an interim regulatory cut-off of 15 ng/mL for methamphetamine in post-race urine is proposed.

Influence Of Dietary Component Manipulation And Feed Management Strategies On Growth And Rumen Development Of Weaned Dairy Heifers, Tana Shea Dennis

Open Access Dissertations

Well-developed replacement heifers provide a central foundation for the continued success of the dairy industry. Emphasis on improving pre-weaned calf nutrition has predominated in the industry, but opportunities exist to improve post-weaning heifer nutrition and management. We aimed to evaluate common feed management strategies seen in the industry and their effects on growth, feed efficiency (G:F), and rumen development of calves from birth to 8 mo of age using pen- and individually-fed animal trials. Little information exists regarding post-weaning performance and rumen development of calves fed conventional or high planes of nutrition pre-weaning; therefore, we evaluated two milk replacer feeding …

Evaluating The Prevalence And Effectiveness Of Breed-Specific Legislation, Felicia E. Trembath

Open Access Dissertations

Dog bites pose a persistent public health problem, which some jurisdictions pass breed-specific legislation (BSL) to address. However, very little non-anecdotal evidence regarding the efficacy of BSL has been presented. Currently, BSL research is hampered by the absence of standard terminology, an established prevalence, or a scientific consensus on its effectiveness. The purpose of this study is to propose standardized terminology for BSL, establish the prevalence of each type of BSL in the USA, and conduct a systematic review of the effectiveness of BSL.

After review of terminology currently in use, as well as review of the regulatory actions of …

Thomas, Amanda Wilhelm, Benjamin R. Sessions, Brady A. Hicks, Donald H. Schlafer, Kenneth L. White, Christopher J. Davies

Animal, Dairy, and Veterinary Science Faculty Publications

Trophoblast cells from bovine somatic cell nuclear transfer (SCNT) conceptuses express major histocompatibility complex class I (MHC-I) proteins early in gestation, and this may be one cause of the significant first-trimester embryonic mortality observed in these pregnancies. MHC-I homozygous-compatible (n = 9), homozygous-incompatible (n = 8), and heterozygous-incompatible (n = 5) SCNT pregnancies were established. The control group consisted of eight pregnancies produced by artificial insemination. Uterine and placental samples were collected on Day 35 ± 1 of pregnancy, and expression of MHC-I, leukocyte markers, and cytokines were examined by immunohistochemistry. Trophoblast cells from all SCNT pregnancies expressed MHC-I, while …

Background: We recently reported the identification of Bacillus sp. NRRL B-14911 that induces heart autoimmunity by generating cardiac-reactive T cells through molecular mimicry. This marine bacterium was originally isolated from the Gulf of Mexico, but no associations with human diseases were reported. Therefore, to characterize its biological and medical significance, we sought to determine and analyze the complete genome sequence of Bacillus sp. NRRL B-14911.

Results: Based on the phylogenetic analysis of 16S ribosomal RNA (rRNA) genes, sequence analysis of the 16S-23S rDNA intergenic transcribed spacers, phenotypic microarray, and matrix-assisted laser desorption ionization time-offlight mass spectrometry, we propose that this …

Skeletal atavism in Shetland ponies is a heritable disorder characterized by abnormal growth of the ulna and fibula that extend the carpal and tarsal joints, respectively. This causes abnormal skeletal structure and impaired movements, and affected foals are usually killed. In order to identify the causal mutation we subjected six confirmed Swedish cases and a DNA pool consisting of 21 control individuals to whole genome resequencing. We screened for polymorphisms where the cases and the control pool were fixed for opposite alleles and observed this signature for only 25 SNPs, most of which were scattered on genome assembly unassigned scaffolds. …
