Toxoplasma gondii is among the most prevalent parasites worldwide, infecting many wild and domestic animals and causing zoonotic infections in humans. T. gondii differs substantially in its broad distribution from closely related parasites that typically have narrow, specialized host ranges. To elucidate the genetic basis for these differences, we compared the genomes of 62 globally distributed T. gondii isolates to several closely related coccidian parasites. Our findings reveal that tandem amplification and diversification of secretory pathogenesis determinants is the primary feature that distinguishes the closely related genomes of these biologically diverse parasites. We further show that the unusual population structure …

Noninvasive Assessment Of Cardiac Abnormalities In Experimental Autoimmune Myocarditis By Magnetic Resonance Microscopy Imaging In The Mouse, Chandirasegaran Massilamany, Vahid Khalilzad-Sharghi, Arunakumar Gangaplara, David Steffen, Shadi F. Othman, Jay Reddy

Jay Reddy Publications

Myocarditis is an inflammation of the myocardium, but only ~10% of those affected show clinical manifestations of the disease. To study the immune events of myocardial injuries, various mouse models of myocarditis have been widely used. This study involved experimental autoimmune myocarditis (EAM) induced with cardiac myosin heavy chain (Myhc)-α 334-352 in A/J mice; the affected animals develop lymphocytic myocarditis but with no apparent clinical signs. In this model, the utility of magnetic resonance microscopy (MRM) as a non-invasive modality to determine the cardiac structural and functional changes in animals immunized with Myhc-α 334-352 is shown. EAM and healthy mice …

Physiology Collection

Recent studies demonstrating a higher incidence of metabolic disorders after calving have challenged the management practice of increasing dietary energy density during the last ~3 wk prepartum. Despite our knowledge at the whole-animal level, the tissue-level mechanisms that are altered in response to feeding management prepartum remain unclear. Our hypothesis was that prepartum body condition score (BCS), in combination with feeding management, plays a central role in the peripartum changes associated with energy balance and inflammatory state. Twenty-eight mid-lactation grazing dairy cows of mixed age and breed were randomly allocated to 1 of 4 treatment groups in a 2 × …

Cobalt Use And Regulation In Horseracing: A Review, K. Brewer, G. Maylin, C. K. Fenger, Thomas Tobin

Veterinary Science Faculty Publications

Cobalt, atomic weight 58.9, is a metallic element and environmental substance found in the animal in microgram quantities, predominantly as vitamin B12, but is also a component of at least one mammalian enzyme unassociated with B12. Cobalt is a required trace mineral and has long been administered as a dietary supplement to humans and animals. Cobalt deficiency outside of its requirement in vitamin B12 has not been reported in humans. The administration of cobalt salts was once standard treatment for anaemia in humans, owing to its ability to stimulate red blood cell synthesis. Elemental cobalt acts by stabilising hypoxia inducible …

Development And Characterization Of A Recombinant Orf Virus Vector Expressing The Spike Protein Of Porcine Epidemic Diarrhea Virus, Kyle Hain

Electronic Theses and Dissertations

Orf virus (ORFV), the type member of the genus Parapoxvirus of the family Poxviridae, causes orf or cutaneous pustular dermatitis in sheep and goats. ORFV is a ubiquitous virus capable of re-infecting its hosts multiple times over time. ORFV causes a non-systemic, self-limiting disease which is usually restricted to the skin surrounding the virus entry sites. ORFV has evolved several immunomodulatory proteins (IMPs) that evade and/or modulate host immune responses to infection and contribute to virus virulence and disease pathogenesis. Given biological properties and unique immunomodula tor y properties, ORFV has gained significant attention in recent years for its …

Chitko-Mckown, Michael L. Clawson

School of Veterinary and Biomedical Sciences: Faculty Publications

Moraxella bovoculi is a recently described bacterium that is associated with infectious bovine keratoconjunctivitis (IBK) or “pinkeye” in cattle. In this study, closed circularized genomes were generated for seven M. bovoculi isolates: three that originated from the eyes of clinical IBK bovine cases and four from the deep nasopharynx of asymptomatic cattle. Isolates that originated from the eyes of IBK cases profoundly differed from those that originated from the nasopharynx of asymptomatic cattle in genome structure, gene content and polymorphism diversity and consequently placed into two distinct phylogenetic groups. These results suggest that there are genetically distinct strains of M. …

The Impact Of Endocrine-Disrupting Chemicals On Wildlife Conservation, Eda Reed

Honors Theses

Endocrine-disrupting chemicals (EDCs), such as those from plastics and pesticides, have been hypothesized to affect wildlife populations. According to the U.S. National Institute of Environmental Health Sciences, EDCs ‘are chemicals that may interfere with the body’s endocrine system and produce adverse developmental, reproductive, neurological, and immune effects in both humans and wildlife.’ A growing number of studies suggest wildlife are being exposed to EDCs, but how EDCs affect wildlife health and wildlife conservation is less well-understood. Through scientific literature analysis and a survey of wildlife conservationists and practitioners, this study aims to determine the current state of knowledge and data …

Poor Placental Traits Reduce Kid Birth Weight In Young Saanen Dams In The First Parity, Uğur Şen, Hasan Önder

Turkish Journal of Veterinary & Animal Sciences

Placental characteristics are the most important indicators of fetal growth and development that influence kid vitality. The aim of this study was to examine the effect of maternal parity on placental characteristics and birth-related traits in Saanen goats. The experiments were conducted on 41 singleton-bearing Saanen does, ranging from 1 to 4 years of age and classified according to first, second, and third parities. Birth weight, placental weight, placental efficiency, and cotyledon density were influenced by parity (P < 0.05). First-parity does had kids with significantly (P < 0.05) lower birth and placental weights than does of other parities, while they had significantly higher (P < 0.05) placental efficiency and cotyledon density. First-parity does had fewer (P < 0.05) large and total cotyledons than third-parity does. Cotyledon dimensions varied among parities (P < 0.05), while average cotyledon surface area and cotyledon efficiency were the lowest in the first-parity does (P < 0.05). The results suggest that younger dams in the first parity may alter placental characteristics and fetal development, resulting in a reduced birth weight from singleton gestations.

Comparison Of Foetal Growth In Singleton And Twin Pregnancies Byb-Mode And Doppler Ultrasonography In Karya Ewes, Güneş Erdoğan, Hayretti̇n Çeti̇n, Ahmet Ceylan, İlker Seri̇n, Hakki Bülent Beceri̇kli̇soy

Turkish Journal of Veterinary & Animal Sciences

Foetal growth and haemodynamic features were investigated in singleton and twin pregnancies in Karya ewes with B-mode/Doppler ultrasonography. Nineteen healthy singleton (n = 9) and twin (n = 10) pregnant Karya ewes were used. Foetal biometric and haemodynamic measurements were made at 15-day intervals on the 29 foetuses during pregnancy. Biparietal head diameter (BPD), thoracic diameter (TD), umbilical cord diameter (UCD), foetal heart rate (FHR), peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI), and resistance index (RI) were recorded. The BPD was higher in twins on days 55 and 130 of pregnancy (P < 0.05), and the TD was higher in singletons on day 115 of pregnancy (P < 0.01). UCD was higher in twins on day 55 of pregnancy (P < 0.01). On day 130 of pregnancy, PSV and EDV were higher in twin foetuses (P < 0.05). PI and RI were lower in twins on day 40 of pregnancy (P < 0.05). Foetal growth and umbilical artery blood flow show some differences depending on the numbers of foetuses and the gestational stage. Additionally, BPD, TD, and FHR were reliable for estimation of gestational age during twin pregnancies.
