Surveillance Of A Novel Vesivirus Discovered In An Urban Mephitis Mephitis Population, Amanda E. Diggins
Surveillance Of A Novel Vesivirus Discovered In An Urban Mephitis Mephitis Population, Amanda E. Diggins
Honors Theses and Capstones
Caliciviridae is a family of non-enveloped, positive-sense, single stranded RNA viruses, including eleven defined genera that contain important pathogens of humans and animals. Within the Caliciviridae family, the genus Vesiviridae includes feline calicivirus, a leading cause of upper respiratory disease in cats, and vesicular exanthema of swine virus, a historical disease of domestic swine that has now been implicated in several marine mammal vesicular diseases, one of which has been confirmed zoonotic. Urban landscapes create a unique environment for rapid intra- and interspecies transmission of viruses. Clustered resources attract high-density populations of synanthropic wildlife species, increasing spatial overlap and heightening …
Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty
Anthelmintic Resistance In Sheep Across Ireland And The Uk: A Literature Review Of The In Vivo Versus In Vitro Methods, Megan Tumulty
SURE Journal: Science Undergraduate Research Experience Journal
Background: The animal welfare and production consequences of gastrointestinal nematode infections, namely Nematodirus battus, on sheep are compelling. The control of gastrointestinal infections has been heavily reliant on the administration of anthelmintics since their introduction into mainstream use in 1960. However, their frequent and often excessive use has resulted in anthelmintic resistance being reported extensively in several gastrointestinal nematode species. The prevalence of anthelmintic resistance as well as the increase in the number of cases of multiple-drug resistance in nematode populations now poses substantial hindrance on the viability of sheep production systems. However, despite the threat N. battus poses …
Dirofilaria Immitis Prevalence In Canis Latrans In Kentucky, Melanie Ann Brandon
Dirofilaria Immitis Prevalence In Canis Latrans In Kentucky, Melanie Ann Brandon
Murray State Theses and Dissertations
Dirofilaria immitis (canine heartworm) was found in forty-two (42) of the two hundred seventy-five (275) Canis latrans (coyote) necropsied in the state of Kentucky from November 27, 2019 through March 3, 2021. Thirty-five (35) of the positive cases were from western Kentucky region with the other seven spread across the state. With this group of coyotes, one hundred fifty-eight (158) were male and the other one hundred six-teen (116) were female. The estimated age ranged from a pup to senior dogs. A little over forty percent of the dogs were obtained through coyote/predator tournaments; the remaining were acquired from pest …
Occurrence Of Pulmonary Arteritis With Lungworm Infections In Gray Seals From New England, 2013-2020, Jillian R. Broadhurst, Inga Sidor Dvm, Ms, Dacvp
Occurrence Of Pulmonary Arteritis With Lungworm Infections In Gray Seals From New England, 2013-2020, Jillian R. Broadhurst, Inga Sidor Dvm, Ms, Dacvp
Honors Theses and Capstones
Gray seals (Halichoerus grypus) are a common pinniped species in New England coastal waters. Parasitic infection is an important cause of mortality for this species, and lungworm species are frequently implicated in cases of respiratory infection, especially in pups and weanling seals. The most common of these is Otostrongylus circumlitus, a large nematode found in the bronchi and bronchioles of affected seals. The full life cycle is unknown but its presence in lungs and sometimes pulmonary arteries suggests that migration via arterial circulation occurs. Signs and microscopic findings are widely variable; our cases included dyspnea, bloody mucoid …
Cellular And Molecular Basis Of Equine Arteritis Virus Persistent Infection In The Stallion Reproductive Tract: Characterization Of Local Host-Pathogen Interactions Mediating Long-Term Viral Persistence, Mariano Carossino
Theses and Dissertations--Veterinary Science
Equine arteritis virus (EAV) has a global impact on the equine industry being the causative agent of equine viral arteritis (EVA), a reproductive, respiratory, and systemic disease of equids. A distinctive feature of EAV infection is that it establishes long-term persistent infection in the reproductive tract of stallions and is continuously shed in the semen (carrier state). Recent studies showed that long-term persistence is associated with a specific allele of the CXCL16 gene (CXCL16S). However, the cellular and molecular mechanisms underlying the establishment and maintenance of persistent infection are yet to be determined. The studies were undertaken herein …

Avian influenza viruses (AIVs) continue to pose a global threat. Waterfowl are the main reservoir and are responsible for the spillover of AIVs to other hosts. This study was conducted as part of routine surveillance activities in Bangladesh and it reports on the serological and molecular detection of H5N1 AIV subtype. A total of 2169 cloacal and 2191 oropharyngeal swabs as well as 1725 sera samples were collected from live birds including duck and chicken in different locations in Bangladesh between the years of 2013 and 2014. Samples were tested using virus isolation, serological tests and molecular methods of RT-PCR. …

Carbon metabolism and virulence determinant production are often linked in pathogenic bacteria, and several regulatory elements have been reported to mediate this linkage in Staphylococcus aureus. Previously, we described a novel protein, catabolite control protein E (CcpE) that functions as a regulator of the tricarboxylic acid cycle. Here we demonstrate that CcpE also regulates virulence determinant biosynthesis and pathogenesis. Specifically, deletion of ccpE in S. aureus strain Newman revealed that CcpE affects transcription of virulence factors such as capA, the first gene in the capsule biosynthetic operon; hla, encoding α-toxin; and psmα, encoding the phenol-soluble modulin cluster α. Electrophoretic mobility …
Evaluating The Formation Of Bacterial Chondronecrosis With Osteomyelitis In Broilers Raised On Portable Wire Floor Models, Alex David Gilley
Evaluating The Formation Of Bacterial Chondronecrosis With Osteomyelitis In Broilers Raised On Portable Wire Floor Models, Alex David Gilley
Graduate Theses and Dissertations
Rearing birds on wire flooring has proven to be an effective method for consistently triggering significant levels of lameness in broilers, and while the wire flooring model has been proven effective, more mobile wire floor models have been developed to compliment the facility management conditions within commercial genetic selection programs. The mobile wire floor models have been titled "speed bumps", and through previous evaluation have resulted in significantly higher levels of lameness in broilers compared to litter floor shavings. The current experiment contains two studies (studies 1 and 2). Both studies involved comparing leg weakness between broiler strains; while in …

Of the Orthomyxoviridae family of viruses, only influenza A viruses are thought to exist as multiple subtypes and has nonhuman maintenance hosts. In April 2011, nasal swabs were collected for virus isolation from pigs exhibiting influenza-like illness. Subsequent electron microscopic, biochemical, and genetic studies identified an orthomyxovirus with seven RNA segments exhibiting approximately 50% overall amino acid identity to human influenza C virus. Based on its genetic organizational similarities to influenza C viruses this virus has been provisionally designated C/Oklahoma/1334/2011 (C/OK). Phylogenetic analysis of the predicted viral proteins found that the divergence between C/OK and human influenza C viruses was …

Female B10.S mice are highly resistant to proteolipid protein (PLP) 139–151-induced experimental autoimmune encephalomyelitis (EAE) and depletion of PLP 139–151- reactive CD4+CD25+regulatory T (Treg) cells can slightly increase their EAE susceptibility. Although male B10.S mice are moderately susceptible to EAE, we report that depletion of Treg cells in male B10.S mice before immunization with PLP 139–151 renders them highly susceptible to severe EAE with more CNS neutrophil infiltrates than nondepleted controls. Increased susceptibility is associated with an enhanced PLP 139–151-specific T cell response and greater production of IFN-γ, IL-6, and IL-17. Male CD4+CD25+ effector cells depleted of Treg cells proliferate …

The Pathophysiology Of Acute Venous Occlusion, Lewis H. Curd Jr.
Biological Sciences Theses & Dissertations
Large artery, pedal small vein, femoral vein and central venous pressures and extremity volume changes were recorded in mongrel dogs in which the hindlimb was perfused at a constant flow. Arterial, pedal venous and femoral venous blood gases were drawn and analyzed for measurements of arterio-venous O2 and CO2 differences. Paw and thigh resistances were calculated. Measurements were repeated following ligation of the iliac and femoral veins, alpha receptor blockade (dibenzyline), and dilation with Vasodilan. Results indicate that ligation of extremity veins results in an active ·increase in total limb resistance below the ligation, an increase in the …
