The Role Of Herpes Simplex Virus Type 1 Glycoprotein K In Neuroinvasion And Immunopathogenesis Of Herpes Keratitis, Ahmad Saied Jan 2015

The Role Of Herpes Simplex Virus Type 1 Glycoprotein K In Neuroinvasion And Immunopathogenesis Of Herpes Keratitis, Ahmad Saied

LSU Doctoral Dissertations

ABSTRACT Herpes simplex virus type 1 is a common neurotropic pathogen responsible for a multitude of human diseases ranging from mucocutaneous lesions, keratitis to life-threatening encephalitis. The hallmark of the HSV-1 life cycle is infection of sensory neurons, where the virus establishes a latent infection for the life of the host. Viral envelope glycoproteins play important roles in viral life cycle and virus-host interaction. Viral glycoproteins gK, gM, gE and the membrane protein UL11 have been shown to be important for virus assembly, egress and virus spread. To investigate the relative importance of each of gK, gM, gE and UL11 …

The Use Of Geographic Information Systems And Ecological Niche Modeling To Map Transmission Risk For Visceral Leishmaniasis In Bahia, Brazil, Moara De Santana Martins Jan 2015

The Use Of Geographic Information Systems And Ecological Niche Modeling To Map Transmission Risk For Visceral Leishmaniasis In Bahia, Brazil, Moara De Santana Martins

LSU Doctoral Dissertations

Leishmaniasis is a public health problem in Brazil, and despite the control programs in place, Bahia remains one of the states with the highest incidence rates of cutaneous leishmaniasis (CL) and visceral leishmaniasis (VL). This study proposed to develop and evaluate the applicability of ecological niche models (ENM) for leishmaniasis, to determine the influence of environmental and socioeconomic factors on the incidence of these diseases at three geographic scales: national, statewide and community. Water availability, garbage collection, precipitation and temperature were the most important variables in predicting areas suitable for VL and CL in the country. The extensive geography of …

Comparative Genomic Studies Of Catfish And Zebrafish Strains Of Edwardsiella Ictaluri, Rui Wang Jan 2015

Comparative Genomic Studies Of Catfish And Zebrafish Strains Of Edwardsiella Ictaluri, Rui Wang

LSU Doctoral Dissertations

Edwardsiella ictaluri is a gram negative bacterium that is the causative agent of enteric septicemia of catfish. In 2011, this bacterium was identified as the causative agent of massive death in zebrafish populations in U.S. In this project, we found that isolates of E. ictaluri from zebrafish comprise a unique strain that differs from the type strain of E. ictaluri phenotypically as well as genetically. Also, strains of E. ictaluri from zebrafish are non-infectious in channel catfish Ictalurus punctatus by immersion. Here we sequenced the zebrafish strains of E. ictaluri LADL11-100 and LADL11-194 and compared the potential virulence genes in …

Development And Characterization Of A Live-Attenuated Vaccine To Combat Equine Herpesvirus Type-1 Infections, Shiliang Anthony Liu Jan 2015

Development And Characterization Of A Live-Attenuated Vaccine To Combat Equine Herpesvirus Type-1 Infections, Shiliang Anthony Liu

LSU Doctoral Dissertations

Equine Herpesvirus 1 (EHV-1) is an important ubiquitous enzootic equine pathogen and one of the most common pathogens of the horse, causing, respiratory disease, epidemic abortion, occasionally neurological disease in horses, which leads to significant economic losses to the horse industry. EHV-1 induces several clinical signs of disease ranging in severity, from mild respiratory disease to abortion in pregnant mares, neonatal foal death and neuropathogenic disorders. Natural EHV-1 infection stimulated short lived protective immunity and had both humoral and cellular immune responses. Currently vaccination remains the best option to prevent EHV-1 infection and different applications of vaccination have been investigated …

The Effects Of Prostatic Fluid On Functional Characteristics Of Cooled Canine Semen, Reto Fritsche Jan 2015

The Effects Of Prostatic Fluid On Functional Characteristics Of Cooled Canine Semen, Reto Fritsche

LSU Master's Theses

The objectives of this study were to investigate concentration dependent effects of canine prostatic fluid (PF) on in vitro seminal parameters of cooled canine semen. Sperm motility parameters, plasma membrane integrity and stability, acrosome integrity and DNA fragmentation were measured after the addition of 0%, 10%, 25%, or 50% PF to extended semen of fertile dogs. Assessments were made at 0 h pre-cooling, at 24, and 48 h of cooled storage (4 °C), and after freezing and thawing followed by incubation (37 °C) at 0, 4 and 24 h. Our hypothesis was that lower dilutions of canine semen with PF …

Correlation Of Ultrasonographic Small Intestinal Wall Layering With Histology In Normal Dogs, Alexandre Benjamin Le Roux Jan 2015

Correlation Of Ultrasonographic Small Intestinal Wall Layering With Histology In Normal Dogs, Alexandre Benjamin Le Roux

LSU Master's Theses

Five intestinal layers are commonly described ultrasonographically in dogs. However, current high-frequency endosonography allows the identification of 9 layers in people. The aim of this study was to describe ex vivo small intestinal layering in dogs and correlate ultrasonographic layering with histological layers. Our hypothesis was that, similar to findings in humans, discrepancies exist in thickness and visibility of intestinal layers between histology and ultrasound in dogs. Twelve adult dogs were included in the study. They were euthanized for reasons unrelated to gastrointestinal disease, but extensive medical history was unavailable. Duodenum, jejunum and ileum samples were resected immediately after euthanasia. …
