Bacterial Chondronecrosis With Osteomyelitis In Broilers: Genomics, Phylogenomics, And Methods To Detect Specific Pathogens During Outbreaks., Abdulkarim Abdulaziz A. Shwani

Graduate Theses and Dissertations

Lameness is a major issue in animal welfare and the broiler industry. Bacterial chondronecrosis with osteomyelitis (BCO) is one of the main causes of lameness. Many staphylococcal species, including Staphylococcus agnetis isolate 908, have been isolated from the bones and blood of lame broilers at the University of Arkansas. Staphylococcus agnetis is a coagulase-variable, Gram-positive bacterial species that has been previously associated with subclinical or mild clinical cases of mastitis in dairy cattle. The annotated complete genome of hypervirulent strain 908 was published at NCBI. In this study, it has been compared to nine genomes we assembled for hypervirulent isolates …

Impact Of Fatty Acid On Markers Of Exocrine Pancreatic Stimulation, Yunyi Zhang

Masters Theses

Chronic pancreatitis in dogs is typically managed with a low-fat diet. Human research suggests consuming medium-chain triglycerides (MCT) may lower pancreatic enzyme release compared to consuming long chain fatty acids (LCFA). Twelve healthy adult colony dogs were fed a meal of cod and rice with either 3% metabolizable energy (ME) fat (control), high MCT (25% ME MCT oil, 25% ME butter), high saturated LCFA (50% ME butter), or high unsaturated LCFA (50% ME canola oil) in a 4-period by 4-treatment crossover design. Serum concentrations of canine pancreatic lipase immunoreactivity, gastrin, amylase, cholecystokinin (CCK), cholesterol, triglycerides and serum activities of DGGR …

Optimising Response To An Introduction Of African Swine Fever In Wild Pigs, Kim M. Pepin, Vienna R. Brown, Anni Yang, James C. Beasley, Raoul Boughton, Kurt C. Vercauteren, Ryan S. Miller, Sarah N. Bevins

USDA Wildlife Services: Staff Publications

African swine fever virus (ASFv) is a virulent pathogen that threatens domestic swine industries globally and persists in wild boar populations in some countries. Persistence in wild boar can challenge elimination and prevent disease-free status, making it necessary to address wild swine in proactive response plans. In the United States, invasive wild pigs are abundant and found across a wide range of ecological conditions that could drive different epidemiological dynamics among populations. Information on the size of the control areas required to rapidly eliminate the ASFv in wild pigs and how this area should change with management constraints and local …

Amplification Of Black Vulture (Coragyps Atratus) Dna From Regurgitated Food Pellets, Daniel R. Taylor, Bryan M. Kluever, John S. Humphrey, Iona M. Hennessy, Amber Sutton, William E. Bruce, Antoinette J. Piaggio

USDA Wildlife Services: Staff Publications

Studies that rely on noninvasive collection of DNA for birds often use feces or feathers. Some birds, such as vultures, regurgitate undigested matter in the form of pellets that are commonly found under roost sites. Our research demonstrates that regurgitated pellets are a viable, noninvasive source of DNA for molecular ecology studies of vultures. Our objectives were to amplify 5 microsatellite loci designed for distinguishing Turkey Vultures (Cathartes aura) and Black Vultures (Coragyps atratus) in a single, multiplexed PCR, and to determine how long the target nuclear DNA persists after a vulture pellet is regurgitated and …

Evaluation Of Residual Antibacterial Effects On Canine Skin Surface And Hairs Following Treatment With Five Commercial Mousse Products Against Staphylococcus Pseudintermedius In Vitro, Chi-Yen Wu

LSU Master's Theses

Topical products are essential treatments for canine superficial bacterial folliculitis. However, studies for commercial products typically evaluate antibacterial effects on hairs rather than the skin surface. In addition, the interference from the hair length has not been evaluated in these studies. Therefore, the study objective for this study was to evaluate the residual antibacterial effects of five mousse products, (1) 2% chlorhexidine and 2% miconazole, (2) 0.05% phytosphingosine, (3) 2% salicylic acid and 10% ethyl lactate, (4) 3% chlorhexidine and 0.5% climbazole, and (5) 2% chlorhexidine and 1% ketoconazole on both the skin surface and hairs in both short- and …

Seasonal Climatic Niche And Migration Movements Of Double-Crested Cormorants, D. Tommy King, Guiming Wang, Fred L. Cunningham

USDA Wildlife Services: Staff Publications

Avian migrants are challenged by seasonal adverse climatic conditions and energetic costs of long-distance flying. Migratory birds may track or switch seasonal climatic niche between the breeding and non-breeding grounds. Satellite tracking enables avian ecologists to investigate seasonal climatic niche and circannual movement patterns of migratory birds. The Double-crested Cormorant (Nannopterum auritum, hereafter cormorant) wintering in the Gulf of Mexico (GOM) migrates to the Northern Great Plains and Great Lakes and is of economic importance because of its impacts on aquaculture. We tested the climatic niche switching hypothesis that cormorants would switch climatic niche between summer and winter …

Understanding How High Levels Of Noise Affect The Equine Auditory System, Shelby Brown

Ursidae: The Undergraduate Research Journal at the University of Northern Colorado

Abstract

Mounted shooting is becoming a very popular sport within the equestrian community, exposing many horses to extreme levels of noise that the animals would not be exposed to otherwise. I selected this project because it is important for me to know how this hobby that I personally enjoy is impacting the health and well-being of my equine partners. Veterinarians can provide an elementary answer by clapping and checking for a physical reaction. However, that does not tell the client much other than the animal responded to one auditory cue.

It is important to understand how firearm exposure could affect …

Tropical forest understory regeneration occurs rapidly after disturbance with compositional trajectories that depend on species availability and environmental conditions. To predict future tropical forest regeneration dynamics, we need a deeper understanding of how pulse disturbance events, like hurricanes, interact with environmental variability to affect understory demography and composition. We examined fern and sapling mortality, recruitment, and community composition in relation to solar radiation and soil moisture using 17 years of forest dynamics data (2003–2019) from the Canopy Trimming Experiment in the Luquillo Experimental Forest, Puerto Rico. Solar radiation increased 150% and soil moisture increased 40% following canopy trimming of experimental …

Jeffrey Root

USDA Wildlife Services: Staff Publications

Rabbit haemorrhagic disease virus (RHDV) is associated with high morbidity and mortality in the European rabbit (Oryctolagus cuniculus). In 2010, a genetically distinct RHDV named RHDV2 emerged in Europe and spread to many other regions, including North America in 2016. Prior to this study it was unknown if eastern cottontails (ECT(s); Sylvilagus floridanus), one of the most common wild lagomorphs in the United States, were susceptible to RHDV2. In this study, 10 wild-caught ECTs and 10 New Zealand white rabbits (NZWR(s); O. cuniculus) were each inoculated orally with either RHDV (RHDVa/GI.1a; n = 5 per species) or RHDV2 (a recombinant …

Genomic Tools Reveal Complex Social Organization Of An Invasive Large Mammal (Sus Scrofa), Chelsea L. Titus, Courtney F. Bowden, Timothy J. Smyser, Stephen L. Webb, James C. Beasley

USDA Wildlife Services: Staff Publications

A comprehensive understanding of sociality in wildlife is vital to optimizing conservation and management efforts. However, sociality is complicated, especially for widely distributed species that exhibit substantive behavioral plasticity. Invasive wild pigs (Sus scrofa), often representing hybrids of European wild boar and domestic pigs, are among the most adaptable and widely distributed large mammals. The social structure of wild pigs is believed to be similar to European wild boar, consisting of matriarchal groups (sounders) and solitary males. However, wild pig social structure is understudied and largely limited to visual observations. Using a hierarchical approach, we incorporated genomic tools …

Diagnostic Imaging And Hematological And Cytological Analyses Play A Vital Role In Clinical Investigation And Selection Of Therapeutic Approaches In A Polo Pony With Septic Olecranon Bursitis, Rungrueang Yodsheewan, Ravisara Limsripan, Metha Chanda

The Thai Journal of Veterinary Medicine

A 19-year-old gelding polo pony was presented with a prominent protuberance at the tip of the right elbow and five days later, developed a marked swelling on the entire right foreleg with a high fever. Ultrasonography, performed on the caudal elbow region, demonstrated heterogeneous echogenic materials encapsulated in the fibrous capsule. The initial hematological analysis revealed anemia and a normal white blood count (WBC). Hyperbilirubinemia was detected biochemically. Pale yellow/turbid fluid was aspirated from the protuberance area, which showed septic exudate characteristics and contained Streptococcus spp. The pony was diagnosed with septic olecranon bursitis associated with streptococcal infection. The fluid-filled …
