Relative Hepatotoxocity, Carcinogenicity, And Toxicogenomics Of Select Dehydropyrrolizidine Alkaloids In Mice, Michael J. Clayton Dec 2023

Relative Hepatotoxocity, Carcinogenicity, And Toxicogenomics Of Select Dehydropyrrolizidine Alkaloids In Mice, Michael J. Clayton

All Graduate Theses and Dissertations, Fall 2023 to Present

Dehydropyrrolizidine alkaloids are arguably the most important plant derived toxins in terms of impact on human and animal health. Dehydropyrrolizidine alkaloids are a large group of chemically related compounds found in 3% of flowering plants worldwide. Human exposure occurs from ingestion of herbal products including teas supplements or contaminated grain. Animals are exposed through contaminated feed or grazing. There are at least 350 identified toxic PAs, from more than 6,000 plants. The toxins primarily cause liver damage, but some are proven to cause cancer. Indidvidual dehydropyrrolizidine alkaloids vary in their toxic effects. Riddelliine is the only dehydropyrrolizidine alkaloid with extensive …

Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody Dec 2021

Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Avian species are highly susceptible to the hepatotoxic mycotoxin aflatoxin B1 (AFB1). Domesticated turkeys are exquisitely sensitive, due to a combination of highly-efficient hepatic cytochrome P450 (CYP)-mediated bioactivation, and to dysfunctional alpha-class glutathione S-transferases (GSTAs) which typically detoxify the bioactivated electrophilic metabolite exo-AFB1-8,9-epoxide (AFBO). Wild turkeys are relatively resistant to AFB1 in large part due to expression of functional GSTAs. Quail, a related Galliforme, are slightly less sensitive in vivo to AFB1, but whether this is related to the hepatic metabolic profiles of these two critical enzymes has not been rigorously evaluated. …

Control Efforts And Serologic Survey Of Pseudorabies And Brucellosis In Wild Pigs Of Tennessee, Lisa I. Muller, Neelam C. Poudyal, Roger Applegate, Chuck Yoest Jan 2019

Control Efforts And Serologic Survey Of Pseudorabies And Brucellosis In Wild Pigs Of Tennessee, Lisa I. Muller, Neelam C. Poudyal, Roger Applegate, Chuck Yoest

Human–Wildlife Interactions

European wild pigs (Sus scrofa) are an introduced invasive species that now constitute a major threat to agriculture and the natural ecology of the environments they now inhabit. Wild pigs also carry many diseases known to infect wildlife, humans, and livestock. Two of these diseases, pseudorabies (PRV) and brucellosis, constitute major diseases in the United States. Better data are needed regarding the prevalence of these diseases in wild pigs to understand and manage the potential risks to wildlife, humans, and livestock. From July 1, 2011 to June 30, 2017, Tennessee Wildlife Resources Agency personnel trapped and euthanized 4,727 …

Hidden Cost Of Disease In A Free-Ranging Ungulate: Brucellosis Reduces Mid-Winter Pregnancy In Elk, Gavin C. Cotterill, Paul C. Cross, Arthur D. Middleton, Jared D. Rogerson, Brandon M. Scurlock, Johan T. Du Toit Oct 2018

Hidden Cost Of Disease In A Free-Ranging Ungulate: Brucellosis Reduces Mid-Winter Pregnancy In Elk, Gavin C. Cotterill, Paul C. Cross, Arthur D. Middleton, Jared D. Rogerson, Brandon M. Scurlock, Johan T. Du Toit

Wildland Resources Faculty Publications

Demonstrating disease impacts on the vital rates of free‐ranging mammalian hosts typically requires intensive, long‐term study. Evidence for chronic pathogens affecting reproduction but not survival is rare, but has the potential for wide‐ranging effects. Accurately quantifying disease‐associated reductions in fecundity is important for advancing theory, generating accurate predictive models, and achieving effective management. We investigated the impacts of brucellosis (Brucella abortus) on elk (Cervus canadensis) productivity using serological data from over 6,000 captures since 1990 in the Greater Yellowstone Ecosystem, USA. Over 1,000 of these records included known age and pregnancy status. Using Bayesian multilevel models, …

Comparison Of Chikungunya Virus Strains In Disease Severity And Susceptibility To T-705 (Favipiravir), In Vitro And In Vivo, Makda Gebre Aug 2017

Comparison Of Chikungunya Virus Strains In Disease Severity And Susceptibility To T-705 (Favipiravir), In Vitro And In Vivo, Makda Gebre

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Chikungunya is a mosquito-transmitted disease caused by Chikungunya virus (CHIKV). Symptoms of Chikungunya include debilitating joint pain and swelling, fever and rash. CHIKV was first discovered in 1953 in Tanzania, and has since caused periodic outbreaks of disease. The virus reemerged recently in 2004 and has since spread around the world affecting more than 3 million people. The different strains of CHIKV have been grouped into three phylogenetic clades: West African, Asian and East/Central/South African (ECSA). There are no FDA approved medicines or vaccines used to treat or prevent CHIKV infection. The antiviral drug, T-705 (commercially known as Favipiravir), has …
