Production, Characterization, And Diagnostic Application Of Monoclonal Antibodies Against The N-Protein Of Avian Metapneumovirus Subgroup B, Ravi Gupta

Electronic Theses and Dissertations

Avian metapneumovirus (aMPV) is a respiratory pathogen that causes Turkey Rhinotracheitis (TRT) in turkeys and Swollen Head Syndrome (SHS) in chickens. The infection leads to facial swelling, nasal discharge, reduced egg production, and poor growth. This virus is classified into four subgroups: aMPV-A, B, C, and D, with two other novel subgroups, in which aMPV-A, B, and C are most prevalent in the commercial flocks. In early 2024, aMPV-A and B outbreaks have been reported in the US, resulting in severe economic losses. An economic assessment estimates around $112 million in losses in Minnesota and up to $434 million in …

Impacts Of Early/Mid-Gestation Shearing On Umbilical Blood Flow And Lamb Birth Weight, Mara Johnson

Electronic Theses and Dissertations

Studies outside the USA have reported that shearing pregnant ewes during mid to late gestation increases lamb birth weight. Our hypothesis was that shearing pregnant ewes on day 50 of gestation would increase umbilical blood flow (UBF), fetal size, lambing and placental weights. Twenty-eight Polypay ewes were randomly assigned to two treatments: shorn (S) and sham-shorn (Control, CON) and divided in singleton (S: n=4; CON: n=4), twins (S: n=5; CON: n=5) and triplets (S: n=5; CON: n=5). Umbilical BF and fetal and placental measurements were obtained via ultrasonography every 10 days from day 50 to 110 of gestation. Lamb birth …

Isolation, Molecular Characterization, And Epidemiological Analysis Of An Emerging Avian Metapneumovirus Subgroup B In Us Poultry, Sumit Jangra

Electronic Theses and Dissertations

Avian metapneumovirus (aMPV) is one the most economically important poultry respiratory pathogens belonging to the family Pneumoviridae and genus Metapneumovirus, which can affect both domestic and wild birds. aMPVs are classified into four subgroups (A, B, C, and D) based on the level of genetic variations and antigenic differences. aMPV causes turkey rhinotracheitis (TRT) and swollen head syndrome (SHS) in turkeys and chickens respectively. Recently, outbreaks of respiratory disease in meat-type birds and a significant decline in egg production with respiratory signs in breeders were reported from different states in the USA. Isolating aMPV is challenging as it is a …

Abelson (Abl) Tyrosine Kinase Inhibitors Reduce Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Replication In Vitro, Jenna Parliament

Electronic Theses and Dissertations

Porcine reproductive and respiratory syndrome virus (PRRSV) is an enveloped, positive-sense, single-stranded RNA virus from the Arteriviridae family. PRRSV causes respiratory illness and reproductive failure in infected pigs. Outbreaks occurring in the United States and worldwide cause significant economic losses annually. Abelson (Abl) tyrosine kinase is a non-receptor tyrosine kinase, which plays a central role in regulating many cellular processes such as actin reorganization, cell proliferation and differentiation by transducing extracellular and intracellular signals. Abl inhibitors have been shown to restrict the entry of membrane fusion of enveloped viruses, such as severe acute respiratory syndrome coronavirus, Middle Eastern respiratory syndrome …

Whole Genome Sequencing For Identification Of Putative Causative Alleles For Hemochromatosis In Horses, Anna M. Rauber-Ramos

Schultz-Werth Award Papers

Hemochromatosis is liver disorder in which excess iron is stored in the liver, leading to iron overload and extensive liver damage that can prove fatal. Based on human precedence, a genetic cause for idiopathic hemochromatosis in horses is suspected. Two horses with hemochromatosis were whole genome sequenced, with variants in candidate genes prioritized in analyses of potential pathogenicity. No clear putative variants were found to be present in both horses, suggesting an etiology more complex than the initially suspected Mendelian inheritance. A heterozygous nonsense mutation in STEAP3 metalloreductase (STEAP3) was identified as a potential contributor to hemochromatosis in one of …

Mastitis is a significant problem in the dairy industry, posing numerous challenges for dairy farmers worldwide. Mastitis refers to the inflammation of the mammary gland, primarily caused by bacterial infections. This condition affects the health and well-being of dairy cows and has severe economic implications for farmers and overall dairy production. The prevalence of mastitis substantially threatens milk quality, productivity, and profitability, making it a top concern in the dairy industry. Preventing mastitis in cows is crucial for maintaining the herd's health and ensuring highquality milk production. Nutritional strategies have recently gained greater attention due to a direct impact on …

A Comparison Of Mini-Flotac And Mcmaster Techniques, Overdispersion And Prevalence Of Parasites In Naturally Infected North American Bison (Bison Bison) In The Usa, Wiliam L. Johnson, Samantha Reynolds, Colton L. Adkins, Bradly Wehus-Tow, Jameson R. Brennan, Catherine B. Krus, Danielle Buttke, Jeff M. Martin, Jeba R.J. Jesudoss Chelladurai

Natural Resource Management Faculty Publications

Several quantitative diagnostic techniques are available to estimate gastrointestinal parasite counts in the feces of ruminants. Comparing egg and oocyst magnitudes in naturally infected samples has been a recommended approach to rank fecal techniques. In this study, we compared the Mini-FLOTAC (sensitivity of 5 eggs per gram (EPG)/oocysts per gram (OPG)) and different averaged replicates of the modified McMaster techniques (sensitivity of 33.33 EPG/OPG) in 387 fecal samples from 10 herds of naturally infected North American bison in the Central Great Plains region of the USA. Both techniques were performed with fecal slurries homogenized in a fill-FLOTAC device. In the …

Genistein-Enriched Pig Gut Microbiota Library As A Potential Probiotic Consortium, Theresah Amponsah

Electronic Theses and Dissertations

Plant-based diets contain numerous flavonoid compounds that produce antibacterial effects and gut health improvement. Genistein is among the most abundant isoflavones present in a plant-based diet and can be found in high amounts in soy products (up to 1g Kg-1). We describe here a robust method to identify genistein tolerant and metabolizing bacteria in swine gut microbiota and to screen the strains that have antibacterial and immunestimulatory properties. Such strains could be developed as non-antibiotic alternatives to prevent enteric infections in pigs and improve gut immunity. To this end, a mini bioreactorbased system was used to enrich genistein metabolizing bacteria …

Emerging Respiratory Viral Pathogens, April Nelsen

Electronic Theses and Dissertations

Respiratory disease is arguably the most important health concern for the production animal industry [1-3]. Respiratory problems accounted for the highest mortality both in the swine and beef industries [1, 4]. Respiratory pathogens remain the most vital for swine and bovine research and disease monitoring [2, 5-7]. As pathogens, in particular viral pathogens, mutate, novel disease-causing viruses emerge, and there becomes an increasing concern and need for identification with control perimeters. One frequently identified disease syndrome is Porcine Respiratory Disease Complex (PRDC). PRDC is characterized by pneumonia of mixed respiratory infections with contributions from the environment and management practices. The …

Role Of Host Restriction Factors On Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Replication, Pratik Katwal

Electronic Theses and Dissertations

In this study, the role of IFITM3 on PRRSV replication was studied in vitro by expressing exogenous IFITM3 in MARC-145 cells. An average of 31% reduction in PRRSV N protein expression and an average of 5.4 fold decrease in virus titer in the supernatant were observed in IFITM3 overexpressing cells as compared to vector control cells at 24 hours post infection (hpi). Moreover, there was a positive correlation between interferon- induced IFITM3 up-regulation and reduced PRRSV replication. To determine the role of endogenous IFITM3 in PRRSV replication, siRNA induced knockdown of IFITM3 was employed. RT-PCR validated the successful silencing of …

Production Of Monoclonal And Polyclonal Antibodies Against Prrsv Mlvd23-S Tag Peptide Sequence, Katelyn Bettin

Schultz-Werth Award Papers

Porcine reproductive and respiratory syndrome virus (PRRSV) is an RNA virus which belongs to the family Arteriviridae. Since its emergence in the late 1980’s and early 1990’s, PRRSV has had a major economic effect on the swine industry. The most notable effects of this disease are respiratory distress in piglets and late-term pregnancy failures in sows. To track and control spread of this disease, the industry must be able determine which animals have been naturally infected with PRRSV as this contributes to major disease outbreaks and localized pandemics. While vaccines help control the spread of a disease, they also …

Viral And Immune Studies On Bovine Viral Diarrhea Virus (Bvdv) In Bovine Species, Karim Abdelsalam

Electronic Theses and Dissertations

BVDV is a major pathogen of ruminants that causes immune dysfunction and lead to secondary bacterial infection. The underlying mechanism of this dysfunction is not well understood. Based on previous results, we believe that macrophages play a central role in BVDV-associated immune dysfunction. Previously, we have shown that the infected monocyte-derived macrophage (MDM) supernatant of the high virulent strains of BVDV significantly induced lymphocyte apoptosis. In the current study, we performed experiments to identify the apoptotic factors in the infected MDM supernatants in vitro. Also, we have extended our investigation to include testing the impact of infected macrophages on neutrophil …

Cortisol In Hair As A Measure Of Chronic Stress During Sow Gestation And The Pattern Of Cortisol In Blood During Parturition In Sows, Talia Everding

Electronic Theses and Dissertations

Cortisol is known as the stress hormone, as it influences many metabolic processes to maintain glucose homeostasis during stressful experiences, including physical and psychological stress. It can be detected in biological matrices such as blood and hair and is released rapidly during sudden stressors and continuously during longterm stress. Blood cortisol fluctuates rapidly in response to acute stressors like pain, exertion, and fear; in hair cortisol accumulates steadily over the period of hair growth and may be useful for detecting chronically elevated cortisol resulting from long-term stress. The objective of this research was to, 1) determine the influence of a …
