Evaluation Of Ocelot And Bobcat General And Reproductive Health In South Texas And Assessment Of Assisted Reproductive Techniques For Wild Felid Conservation, Ashley Reeves

Doctoral Dissertations

Recent studies of wild felid populations in southern Texas have shown loss of genetic variability and inbreeding depression over time, increasing the risk of reduced reproductive and immune fitness leading to an overall decrease in reproductive success, increase in disease susceptibility, and further population demise. Assessment of general health, pathogen exposure, and reproductive health can provide documentation of the possible effects of inbreeding and inform the development of conservation strategies. Assisted reproductive technologies have been used in many other species and can address behavioral or physical incompatibilities among breeding pairs, connect distant populations by transporting frozen gametes, preserve genetic diversity …

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 …

Diversidad Y Distribución De Mamíferos Voladores En El Corregimiento De Punto Nuevo Municipio De Yopal, Casanare Y Su Impacto En La Comunidad, Karen Lorena Navarro Leal

Biología

Los llanos Orientales se distinguen por su variedad de ecosistemas, los cuales albergan una gran diversidad de especies de mamíferos arborícolas, terrestres, voladores, acuáticos y semiacuáticos, encontrándose allí ´´especies clave´´ con mayor importancia ecológica, ya que su deterioro o desaparición podría ocasionar daños irreversibles en el ecosistema. Por su parte, los murciélagos actúan como agentes de control biológico, hacen posible la polinización y están implicados en procesos de dispersión de semillas, siendo estos, ´´especies clave´´ en el equilibrio ecosistémico preservando la biodiversidad de un bosque. Sin embargo, a pesar de su gran valor ecológico se encuentran sujetos a innumerables conflictos …

Equine Arteritis Virus Has Specific Tropism For Stromal Cells And Cd8+ T And Cd21+ B Lymphocytes But Not For Glandular Epithelium At The Primary Site Of Persistent Infection In The Stallion Reproductive Tract, Mariano Carossino, Alan T.

Equine arteritis virus (EAV) has a global impact on the equine industry as the causative agent of equine viral arteritis (EVA), a respiratory, systemic, and reproductive disease of equids. A distinctive feature of EAV infection is that it establishes long-term persistent infection in 10 to 70% of infected stallions (carriers). In these stallions, EAV is detectable only in the reproductive tract, and viral persistence occurs despite the presence of high serum neutralizing antibody titers. Carrier stallions constitute the natural reservoir of the virus as they continuously shed EAV in their semen. Although the accessory sex glands have been implicated as …

Whole Genomic Sequence Analysis Of Bacillus Infantis: Defining The Genetic Blueprint Of Strain Nrrl B-14911, An Emerging Cardiopathogenic Microbe, Chandirasegara Massilamany, Akram Mohammed, John Dustin Loy, Tanya Purvis, Bharathi Krishnan, Rakesh H.

Background: We recently reported the identification of Bacillus sp. NRRL B-14911 that induces heart autoimmunity by generating cardiac-reactive T cells through molecular mimicry. This marine bacterium was originally isolated from the Gulf of Mexico, but no associations with human diseases were reported. Therefore, to characterize its biological and medical significance, we sought to determine and analyze the complete genome sequence of Bacillus sp. NRRL B-14911.

Results: Based on the phylogenetic analysis of 16S ribosomal RNA (rRNA) genes, sequence analysis of the 16S-23S rDNA intergenic transcribed spacers, phenotypic microarray, and matrix-assisted laser desorption ionization time-offlight mass spectrometry, we propose that this …

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 …

Gender Differences In Cns Autoimmunity Induced By Mimicry Epitope For Plp 139–151 In Sjl Mice, Chandirasegara Massilamany, Sivasubramani Thulasingam, David Steffen, Jay Reddy

Jay Reddy Publications

Development of multiple sclerosis (MS) is more prevalent in females than in males, but the underlying mechanisms are not clear. Microbial infections have been suspected as triggers of MS and it is not known whether gender differences in reactivity to environmental antigens contribute to the disease pathogenesis. We demonstrated that ACA 83–95, a mimicry epitope from Acanthamoeba castellanii for proteolipid protein (PLP) 139–151, induces clinical signs of encephalomyelitis in both male and female SJL mice. Conversely ACA 83–95-induced effector cells from males fail to induce disease in female mice. Although we found no gender differences in the frequencies of antigen-specific …

Two Causes Of Reduced Profit From Pigs, G A L Ward

Journal of the Department of Agriculture, Western Australia, Series 4

LOSS of condition in a pig affects profits more severely than slow rate of growth.

Two common symptoms, scouring and itching, cause weight loss and are followed by a period of reduced weight gain.

FACTORS other than physical faults often cause infertility of rams.

Obviously, it is important to distinguish between temporary and permanent infertility to apply the proper remedy.
