The Effect Of The Nematode Trapping Fungus Duddingtonia Flagrans Against Gastronintestinal Nematodes Of Exotic Ruminant Hoofstock At Disney's(R) Animal Kingdom Lodge, 2018 Louisiana State University and Agricultural and Mechanical College
The Effect Of The Nematode Trapping Fungus Duddingtonia Flagrans Against Gastronintestinal Nematodes Of Exotic Ruminant Hoofstock At Disney's(R) Animal Kingdom Lodge, Kristen Renee Young
LSU Master's Theses
Gastrointestinal nematodes (GIN) can severely affect the performance of ruminant animals and may lead to an animal’s death in a severe, untreated infection. Zoological parks, which have used anthelmintic drugs for treatment of GIN, are now seeing evidence of drug resistant parasites (Garretson et al., 2009). Duddingtonia flagrans, a nematophagous fungus, has shown a reduction in larvae of coprocultures of exotic ruminants through feed administration at Disney's® Animal Kingdom Lodge (DAKL) and has potential to biologically control forage larvae (Terry, 2013). This study evaluated the effectiveness of Duddingtonia flagrans, administered to exotic ruminant hoofstock at a daily dose ...

Zika virus (ZIKV) causes no-to-mild symptoms or severe neurological disorders. To investigate the importance of viral and host genetic variations in determining ZIKV infection outcomes, we created three full-length infectious cDNA clones as bacterial artificial chromosomes for each of three spatiotemporally distinct and genetically divergent ZIKVs: MR-766 (Uganda, 1947), P6-740 (Malaysia, 1966), and PRVABC-59 (Puerto Rico, 2015). Using the three molecularly cloned ZIKVs, together with 13 ZIKV region-specific polyclonal antibodies covering nearly the entire viral protein-coding region, we made three conceptual advances: (i) We created a comprehensive genome-wide portrait of ZIKV gene products and their related species, with several previously ...

Type 2 Bovine Viral Diarrhea Virus NPro Suppresses Type I Interferon Pathway Signaling In Bovine Cells And Augments Bovine Respiratory Syncytial Virus Replication, Abdulrahman Abdulaziz A. Alkheraif
Dissertations & Theses in Veterinary and Biomedical Science
Bovine viral diarrhea virus (BVDV) and bovine respiratory syncytial virus (BRSV) infections contribute to the bovine respiratory disease complex (BRDC), which is a multi-factorial disorder involving co-infections of viruses and bacteria including mycoplasma. BRDC causes great economic losses to the United States feedlot industry. BVDV infection induces immunosuppression in infected animals. BVDV Npro binds and degrades the transcription factor interferon regulatory factor-3 (IRF-3) and effectively blocks type I interferon (type I IFN) expression in host cells. BRSV nonstructural proteins, NS1 and NS2, block activation of IRF-3. In calves, concurrent infection with BVDV and BRSV resulted in more severe clinical signs ...

Data was split into pre- and post-regulation changes, and then divided further into ...
Improving Techniques To Study Equine Cervical Mucociliary Clearance, 2018 University of Maine
Improving Techniques To Study Equine Cervical Mucociliary Clearance, Melissa A. Hawkes
Electronic Theses and Dissertations
Bacterial uterine infections inflict major losses on the equine breeding industry. These infections usually arise from bacteria introduced at breeding. Micro-currents propelled by ciliated cells between the folds of the uterus and cervix have been proposed as a means by which contaminants are expelled. Previous data have shown possible ciliary micro-currents propelling carbon particles, occasionally rotating, through cervical folds. However, adherence to the epithelium may have interfered with movement of carbon in these studies. Therefore, we tested potentially non-adherent substances to reveal ciliary micro-currents on the equine cervix under high magnification video-endoscopy. We hypothesized that polyethylene green microspheres 1 - 5 ...
The Effect Of High Maternal Milk Production During Pregnancy On Neonatal Health And Metabolism, 2018 University of Rhode Island
The Effect Of High Maternal Milk Production During Pregnancy On Neonatal Health And Metabolism, Katelynn Cameron, Maria L. Hoffman Phd
Senior Honors Projects
The efficiency of the dairy industry relies heavily on the production of healthy calves. However, dairy operations experience high rates of calf mortality due to digestive and respiratory issues. One factor that could predispose calves to disease is the effects of maternal programming caused by high maternal milk production during pregnancy. We hypothesized that calves born to high producing dams will exhibit increased oxidative stress as well as increased circulating triglyceride and total cholesterol concentrations. Cows (n = 17) that produced ≥ 14,865 kg of milk during their lactations were classified as high producers. Alternately, cows (n = 18) that produced ≤ 10 ...
A Characterization Of Poultry Flocks And Poultry Producers In Maine, 2018 University of Maine
A Characterization Of Poultry Flocks And Poultry Producers In Maine, Alice Gluchanicz
This study sought to characterize backyard poultry flocks and poultry producers’ knowledge of poultry husbandry in Maine. A survey on poultry flock characterization, management, and health was sent to poultry producers living in Maine. Based on the survey, most backyard poultry flocks contained 7-20 birds. Chickens were the predominant poultry species in Maine. Flocks were used primarily for egg production and companionship. Management practices varied greatly among producers, indicating a need for more flock management education. Mites and coccidiosis were the most commonly reported causes of illness by producers, but several diseases affected poultry in Maine. Producers cited the internet ...

Effects Of Fescue Toxicosis On Whole Blood Gene Expression In Beef Cattle, Julie Atchley
Animal Science Undergraduate Honors Theses
Effects of Fescue Toxicosis on Whole Blood Gene Expression in Beef Cattle
The consumption of endophyte-infected tall fescue causes negative effects on the growth, reproduction, longevity, and overall health of beef cattle; this condition, termed fescue toxicosis by researchers and producers today, costs the United States over $1 billion in losses each year. To mitigate these production losses, it is important for producers to understand how fescue toxicosis affects gene expression and physiological pathways in beef cattle. This study examined the whole blood gene expression and affected pathways in beef cows grazing both endophyte-infected (toxic) tall fescue and (non-toxic) tall ...
