Veterinary Science Faculty Publications

Rotaviral diarrhea in foals is caused by two dominant G3P[12] and G14P[12] genotypes of equine rotavirus A (ERVA). Protection of foals against ERVA infection and disease is achievable by passive antibody transfer through colostrum from mares receiving inactivated monovalent G3P[12] vaccine. Simian rotavirus SA11 G3P[2] is also included in ERVA vaccines to protect foals. Here, we characterized cross-neutralization and protection among three distinctive rotaviruses carrying the same or different G (defined by VP7) or P (defined by VP4) genotype by using a rabbit and equine monospecific antisera panel coupled with structural and computational analyses of viral epitopes. Data from these …

Maxwell H. Gluck Equine Research Center Faculty Publications

Dextrorphan is a Phase I equine metabolite of dextromethorphan, a widely used anti-tussive / cough suppressant medication marketed and available in numerous over-the-counter formulations in the United States. Dextromethorphan is an Association of Racing Commissioners International (ARCI) drug class 4 penalty class B substance and a Horseracing Integrity and Welfare Authority (HIWU) CONTROLLED S7 B substance and is regulated as such in horse racing. In horses, dextromethorphan is metabolized to its Phase I metabolite, dextrorphan, which is next glucuronidated and the resultant dextrorphan-glucuronide conjugate then excreted at remarkably high concentrations in equine urine. Dextrorphan is therefore at times identified in …

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 …

Expression Pattern Of The Hifα-Family In Equine Chorioallantois During Pregnancy And Placental Pathology, Yatta Boakari, Hossam El-Sheikh Ali, Gustavo Henrique Doná Rodrigues Almeida, Kirsten E. Scoggin, Claudia Barbosa Fernandes, Sophia Panelli Marchio, Mats H. T. Troedsson, Ana Claudia Oliveira Carreira

Maxwell H. Gluck Equine Research Center Faculty Publications

Equine placental dysfunction impairs fetal growth and disrupts pregnancy outcomes. Despite many advances in diagnosis, the molecular pathophysiology of equine placentitis and premature placental separation remains poorly understood. However, the hypoxia-inducible factor (HIF-α) pathway is related to placental hypoxia, and its modulation in placental diseases has been shown in other species. Therefore, we hypothesized that in conditions marked by equine placental dysfunction, oxygen deprivation in the chorioallantois membrane triggers the activation of the HIF-α pathway, which is related to molecular alterations associated with placental insufficiency. Accordingly, we compared the expression of HIF1A, HIF2A, HIF3A, and HIF1AN genes in equine chorioallantois …

Investigating The Potential Role Of Toxoplasma Gondii In The Development Of Equine Protozoal Myeloencephalitis, Brooklyn Nicole Shirah

Theses and Dissertations--Veterinary Science

Equine protozoal myeloencephalitis (EPM) is a neurologic disease of horses prevalent in the Americas, caused by the coccidian parasites Sarcocystis neurona and Neospora hughesi. Toxoplasma gondii is a related parasite that infects nearly all warm-blooded animals, including horses. Prior studies show conflicting results on whether T. gondii contributes to EPM, in part because no validated T. gondii serologic assay exists in horses. This study developed a recombinant TgSAG1 ELISA and confirmatory Western blot. These assays evaluated T. gondii seropositivity in 789 serum samples from healthy and neurologic horses across multiple geographic regions and examined 31 paired serum:CSF samples for …

Environmental Detection And Quantification Of Equid Alphaherpesviruses In Equine Facilities Using Air Sampling, Emma E. Hyde

Theses and Dissertations--Veterinary Science

Equid alphaherpesvirus 1 and 4 (EHV-1/-4) circulate at equestrian facilities, contributing to outbreaks. Due to the complexities of the pathogen, including the limited predictability of reactivation from latency and the effects associated with secondary sites of viral replication, abortion, and neurologic disease, EHV infections are of utmost concern to the equine industry. Recent studies have highlighted the prevalence of the viruses in stabling areas at competitions, though little is known about this phenomenon in other high-traffic equine environments. This thesis presents two studies using air sampling surveillance methods to further explore the viral detection in other equine environments (veterinary facility …

Comparison Of Spayed Heifer Performance To Intact Heifers Fed Melengestrol Acetate On Feedlot Performance And Carcass Characteristics, Tate S. Johnson, Rebecca L. Mcdermott, Halden J. Clark, Jim C. Macdonald, Jessica L. Sperber

Nebraska Beef Cattle Reports

Summary with Implications

Pregnancy and estrous cycle management are critical considerations when feeding intact heifers in the feedyard. Alternatively, producers can opt to spay heifers, which eliminates hormonal fluctuations associated with the estrous cycle. A proportion of U.S. feedlots have spayed heifers on feed, although there is limited data comparing the performance of spayed heifers to intact heifers. A commercial feedlot experiment was conducted to compare performance between spayed and intact heifers fed melengestrol acetate. Intact heifers had greater ADG and tended to have greater DMI compared to spayed heifers, although no difference in feed conversion was observed. Carcass weight …

Abca12 Frameshift Deletion In Domestic Cats With Ichthyosis Fetalis, Jeanna M. Blake, Melissa P. Swan, Kari J. Ekenstedt

Veterinary Science Faculty Publications

Background: Ichthyosis fetalis (IF), also known as harlequin ichthyosis, is a rare and often fatal autosomal recessive congenital skin disorder. It is characterized by thickened, hard skin plaques and deep skin fissures that limit mobility and cause malformations of the eyes, lips and ears. Affected individuals are highly susceptible to life-threatening infections due to the disruption of the skin's protective barrier. To date, IF and its genetic basis have not been described in domestic cats.

Objectives: To characterize the gross clinical, histopathological and genetic features of IF in two stray, random-bred domestic short-hair (DSH) littermates.

Animals: Two deceased female neonatal …

Estrogen Deprivation During Primate (Papio Anubis) Pregnancy: Impact On Systemic Microvascular Flow And Cardiovascular Development And Function After Birth In Offspring, Sifa Turan, Jeffery S. Babischkin, Graham W. Aberdeen, Gerald J. Pepe, Eugene D. Albrecht

Department of Biomedical and Translational Sciences Faculty Publications

Background

Suppressing estradiol (E₂) during baboon pregnancy lowers offspring skeletal muscle capillary density, vital for insulin-mediated glucose uptake, and induces insulin resistance. We examined whether E₂ deprivation also impairs microvascular flow and cardiac function.

Methods

Offspring of untreated baboons, letrozole-treated baboons, or letrozole plus E₂ (maternal s.c. injections during the second half of gestation) underwent contrast-enhanced microbubble ultrasonography to quantify microvessel flow and echocardiography to assess cardiac performance.

Results

Letrozole reduced maternal serum E₂ by 95% (p <  0.01). In letrozole offspring, microbubble flux rate (β) fell 55% (p <  0.02), replenishment was 5 s slower (p <  0.03), and microvessel flow declined 40% (p = 0.05); all were restored by added E₂. Indices of systolic (isovolumic contraction), diastolic (isovolumic relaxation), global performance (Tei index), and cardiac output were unchanged.

Conclusion

Prolonged gestational E₂ deprivation programs a reduction in microvascular flow without altering cardiac function; maternal E₂ prevents this, supporting E₂'s role in …

Partial Post-Exposure Protection By Topical Inserts Containing Tenofovir Alafenamide Fumarate/Elvitegravir In A Macaque Model Of Rectal Simian Hiv (Shiv) Infection, Natalia Makarova, Tyana Singletary, M. Melissa Peet, Kristen Kelley, Ryan Johnson, Vivek Agrahari, Maria Mendoza, Yi Pan, Walid Heneine, Meredith R. Clark, J. Gerardo García Lerma, Gustavo F. Doncel, James W. Smith

CONRAD Publications

On-demand topical inserts for HIV prevention may be a good option for people who have a low frequency of sexual activity. We recently demonstrated in a preclinical macaque model that rectal application of inserts containing tenofovir alafenamide fumarate (TAF) and elvitegravir (EVG) conferred protection against SHIV infection (93% efficacy) when applied as pre-exposure prophylaxis 4 hours before SHIV exposure. Here, we show that the same inserts provide significant postexposure protection (82.9% efficacy) when applied 4 hours after SHIV exposure. Our findings further support the ongoing clinical development of TAF/EVG inserts for on-demand HIV prevention.

The Impact Of A Nf-Κb Signaling Inhibitor On The Antibacterial Activity Immune Response In The Cat Flea (Ctenocephalides Felis), Caroline M. Singer

College of Graduate Studies: Theses & Dissertations

Ctenocephalides felis are vectors of several bacterial pathogens that cause disease in humans and animals, including Bartonella henselae and Rickettsia felis. Successful pathogen transmission requires that microbes survive the immune defenses of the flea digestive tract following blood feeding. In insects, humoral immune responses are regulated primarily by the Toll and immune deficiency (IMD) signaling pathways, with the IMD pathway serving as the principal defense against Gram-negative bacteria. Although genomic and transcriptional evidence indicate that cat fleas encode and express components of the IMD signaling pathway, the functional roles of individual pathway components within the flea digestive tract remain …

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 …

Skeletal Muscle Myofiber Development In Non-Human Primate Offspring Deprived Of Estrogen In Utero, Phillip J. Gauronskas, Terrie J. Lynch, Eugene D. Albrecht, Gerald J. Pepe

Department of Biomedical and Translational Sciences Faculty Publications

Introduction: We previously showed that baboon offspring born to mothers deprived of estrogen during the second half of gestation exhibited insulin resistance prior to and after the onset of puberty. Moreover, the size of skeletal muscle myofibers and the number of microvessels important for delivery of insulin/glucose to myofibers were lower in near-term fetuses deprived of estrogen during pregnancy, and myofiber capillarization remained reduced in post-pubertal offspring deprived of estrogen in utero. However, it remains to be determined whether skeletal muscle size is restored to normal in animals deprived of estrogen in utero after the onset of puberty/gonadal estrogen production. …

The Environmental Impact On The Development Of Equine Degenerative Myeloencephalopathy, Victoria C. Reynolds

Honors Undergraduate Theses

The objective of this study was to examine potential associations between environmental factors and the progression of Equine Degenerative Myeloencephalopathy (EDM). While environmental contributions to neurodegenerative diseases are increasingly recognized in human patients, little is known about their role in EDM. A comprehensive literature review highlighted the lack of research in this area. Data for this study were collected by Dr. Amy Johnson at the University of Pennsylvania's New Bolton Center. The two main areas studied were a horse’s lifestyle (specifically turnout conditions) and their geographical proximity to chemicals (pesticides, airborne neurotoxins, and water contaminants). Statistical analysis revealed there was …

Application Of Flexible Endoscopy For Gastrointestinal Foreign Body Removal In A Leopard Gecko (Eublepharis Macularius), Jang-Hee Han, Seung Yoon Ahn, Do Na Lee, Seong Chan Yeon

The Thai Journal of Veterinary Medicine

A male captive-bred leopard gecko (Eublepharis macularius) presented with a history of inadvertent ingestion of a rubber tip from forceps during feeding. The foreign body was impalpable on physical examination, while radiographic evaluation confirmed its presence in the stomach. Considering the procedural risks associated with invasive surgical interventions, endoscopic retrieval under general anesthesia was pursued. An initial attempt using a 2.8 mm superfine flexible endoscope with 0.8 mm forceps was unsuccessful due to insufficient stability, which hindered effective navigation to the foreign body. In contrast, a second attempt using a larger 9.2 mm flexible endoscope with 2.3 mm …
