Equine Immunity To Cyathostome Infections, Marie Alexandra Baudena Jan 2003

Equine Immunity To Cyathostome Infections, Marie Alexandra Baudena

LSU Doctoral Dissertations

To study the protective responses of cyathostome-infected ponies, two challenges were performed employing animals with different histories of exposure to these parasites. The hypothesis developed and to be tested in these experiments was that ponies that had longer exposure to cyathostome contaminated pastures would express acquired resistance to infection. The assumption behind this hypothesis was that helminth-naïve ponies infected with cyathostomes would eliminate the infection using only innate immune responses. Whereas previously exposed ponies would eliminate the infection with acquired immune responses, and these would be more effective in ponies with longer exposure to cyathostomes. Thus, helminth-naïve animals would acquire …

Immunological, Hematological, And Serum Biochemical Effects Of High Level Dietary Fish Oil And Vitamin E Supplementation In The Dog, Casey J. Leblanc Jan 2003

Immunological, Hematological, And Serum Biochemical Effects Of High Level Dietary Fish Oil And Vitamin E Supplementation In The Dog, Casey J. Leblanc

LSU Doctoral Dissertations

Inflammation is a component of the innate immune response. However, severe or prolonged inflammation can be detrimental. Dietary n-3 fatty acid supplementation has proven clinical benefits in chronic inflammatory diseases, most likely due to reduced synthesis of inflammatory mediators and inhibition of lymphocyte proliferation and function. The purposes of this study were to characterize alterations in inflammatory mediator production, and lymphocyte proliferation, in dogs fed a diet consisting of 0.65% n-3 fatty acids (DMB) with an n-6:n-3 fatty acid ratio of 3.4:1. Fifteen dogs were randomly assigned to one of three dietary groups for twelve weeks. Group Sunflower oil received …

Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins Jan 2003

Effectiveness Of Copper-Oxide Wire Particles On The Control Of Haemonchus Contortus In Sheep, Ariane Diane Watkins

LSU Master's Theses

Among the gastrointestinal nematode parasites that cause the most problems to small ruminants, Haemonchus contortus is one of major concern. Currently, the control of H. contortus and others is almost entirely based on the use of anthelmintics. Consequently, anthelmintic resistance has developed worldwide and this has become a serious problem in small ruminant nematode parasite control programs. In view of this, there is a need for alternative control methods. The use of Copper-Oxide Wire Particles (COWP) to help reduce parasite burden is one such alternative. Three trials were conducted to determine the effect of COWP on the reduction of H. …

Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary Jan 2003

Optimal Age At Fostering For The Derivation Of Helicobacter Hepaticus-Free Mice, Kem Boullion Singletary

LSU Master's Theses

Helicobacter hepaticus is well established as an unwanted variable in laboratory rodent colonies. Historically, caesarean section and embryo transfer have been used to derive Helicobacter-free mouse colonies. Neonatal transfer of newborn mice onto Helicobacter-free foster dams was recently reported as an alternative method of deriving Helicobacter-free mice, but until now, the age by which pups must be fostered to remain Helicobacter-free was unknown. The purpose of this study was to determine the age by which mouse pups must be fostered to remain H. hepaticus-free. Beginning on the day of birth, 20 C57BL/6 mice were fostered from H. hepaticus-positive parents onto …

Susceptibility Of Bacillus Anthracis To Gamma And Cherry Bacteriophage, Preston A. Fulmer Jan 2003

Susceptibility Of Bacillus Anthracis To Gamma And Cherry Bacteriophage, Preston A. Fulmer

LSU Master's Theses

Bacillus anthracis is a bacterium that causes severe disease mainly in ruminants, but can affect any mammal, including humans. A popular method for the detection of this organism is susceptibility of the bacterial isolate to g bacteriophage. However, to date no study on the resistance of a wide variety of B. anthracis isolates has been conducted. The following study examines the rate of resistance of a wide range of B. anthracis isolates to g phage as well as another phage specific for B. anthracis known as Cherry phage. We also compared susceptibility to phage with another detection method, susceptibility to …

Occupational Hazards And Radiation Safety In Veterinary Practice Including Zoo Veterinary Practice In Australia, Joseph S. Jeyaretnam Jan 2003

Occupational Hazards And Radiation Safety In Veterinary Practice Including Zoo Veterinary Practice In Australia, Joseph S. Jeyaretnam

Theses: Doctorates and Masters

This thesis contains reviews and research on the occupational hazards of zoo veterinary practitioners in Australia. Although occupational hazards have long been recognised in the veterinary profession, little information is available on the number and magnitude of injuries to veterinarians in Australia, the United Kingdom or the United States. Apart from anecdotal accounts and some limited data, most of the available information is on occupational zoonoses, generally well recognized by veterinarians. Other occupational hazards to which veterinarians are exposed have received scant attention. The veterinary practitioner in a zoo environment has to treat a range of captive wild species which …

Role Of Endothelin-1 In The Gastrointestinal Tract Of Horses In Health And Disease, Ramaswamy Monickarasi Chidambaram Jan 2003

Role Of Endothelin-1 In The Gastrointestinal Tract Of Horses In Health And Disease, Ramaswamy Monickarasi Chidambaram

LSU Doctoral Dissertations

Gastrointestinal tract disease is the leading natural cause of death in horses and horses with ischemic intestinal disease have the greatest mortality. We hypothesized there is basal synthesis of endothelin-1 (ET-1) in the intestinal tract of healthy horses that is likely involved in regulating vasomotor tone, secretion and motility and that ET-1 synthesis increases with gastrointestinal tract disease, which may be involved in the pathophysiology of these disorders. Plasma ET-like immunoreactivity was increased in horses with naturally-acquired gastrointestinal disease, compared with normal horses; values were greatest in horses with large intestinal strangulation obstruction, enterocolitis and peritonitis. There was an association …

Development Of The Neonatal Rat As A Model For Sudden Infant Death Syndrome: Cardiorespiratory Effects Of Ethanol, Rhett Whitman Stout

LSU Doctoral Dissertations

The current pathogenesis of Sudden Infant Death Syndrome (SIDS) is unknown. Elevated endogenous ethanol production by gastrointestinal yeast has been proposed as a possible mechanism for SIDS. To investigate the role of ethanol in SIDS, three studies were undertaken. In the first study, transcutaneous blood gas technology was evaluated for repeated monitoring of arterial blood gases. The second study identified the cardiorespiratory responses to inhaled CO2 challenge in juvenile rats, to determine the age corresponding to the age range of peak incidence of SIDS in human infants. Finally, utilizing the optimized juvenile rat model, the cardiorespiratory responses to ethanol and …

Osmosensitive Taurine Release: Does Taurine Share The Same Efflux Pathway With Chloride And Other Amino Acid Osmolytes?, Rodrigo Franco Jan 2003

Osmosensitive Taurine Release: Does Taurine Share The Same Efflux Pathway With Chloride And Other Amino Acid Osmolytes?, Rodrigo Franco

School of Veterinary and Biomedical Sciences: Faculty Publications

Swelling subsequent to hyposmotic conditions activates a process of volume regulation present in most cell types. This volume adjustment is accomplished by osmolyte translocation toward the extracellular space to reach a new osmotic equilibrium. Molecules involved in this homeostatic mechanism have been broadly classified into two categories: organic and inorganic osmolytes. Inorganic osmolytes comprise mainly the intracellular ions K+ and Cl–. Cell swelling–induced activation of separate K+ and Cl– channels has been described in most preparations. Organic osmolytes are grouped in three categories: amino acids, polyalcohols, and methylamines. These osmolytes, particularly taurine, are present in …

Role Of Activator Protein-1 In The Down-Regulation Of The Human Cyp2j2 Gene In Hypoxia, Nicole Y. Marden, Eva Fiala-Beer, Shi-Hua Xiang, Michael Murray

School of Veterinary and Biomedical Sciences: Faculty Publications

The cytochrome P450 (CYP) 2J2 arachidonic acid epoxygenase gene was down-regulated at a pre-translational level in human hepatoma-derived HepG2 cells incubated in a hypoxic environment; under these conditions, the expression of c-Jun and c-Fos mRNA and protein was increased. The 5′-upstream region of the CYP2J2 gene was isolated by amplification of a 2341 bp fragment and putative regulatory elements that resembled activator protein-1 (AP-1)-like sequences were identified. From transient transfection analysis, c-Jun was found to strongly activate a CYP2J2–luciferase reporter construct, but co-transfection with plasmids encoding c-Fos or c-Fos-related antigens, Fra-1 and -2, abrogated reporter activity. Using a series …

School of Veterinary and Biomedical Sciences: Faculty Publications

Nearly all human immunodeficiency virus (HIV) infections are acquired mucosally, and the gut-associated lymphoid tissues are important sites for early virus replication. Thus, vaccine strategies designed to prime virus-specific cytotoxic T lymphocyte (CTL) responses that home to mucosal compartments may be particularly effective at preventing or containing HIV infection. The Salmonella type III secretion system has been shown to be an effective approach for stimulating mucosal CTL responses in mice. We therefore tested ∆phoP-phoQ attenuated strains of Salmonella enterica serovar Typhimurium and S. enterica serovar Typhi expressing fragments of the simian immunodeficiency virus (SIV) Gag protein fused to the …

Roles Of Mycobacterium Smegmatis D-Alanine:D-Alanine Ligase And D-Alanine Racemase In The Mechanisms Of Action Of And Resistance To The Peptidoglycan Inhibitor D-Cycloserine, Zhengyu Feng, Raul G. Barletta

School of Veterinary and Biomedical Sciences: Faculty Publications

D-Cycloserine (DCS) targets the peptidoglycan biosynthetic enzymes D-alanine racemase (Alr) and Dalanine: D-alanine ligase (Ddl). Previously, we demonstrated that the overproduction of Alr in Mycobacterium smegmatis determines a DCS resistance phenotype. In this study, we investigated the roles of both Alr and Ddl in the mechanisms of action of and resistance to DCS in M. smegmatis. We found that the overexpression of either the M. smegmatis or the Mycobacterium tuberculosis ddl gene in M. smegmatis confers resistance to DCS, but at lower levels than the overexpression of the alr gene. Furthermore, a strain overexpressing both the alr and ddl …

Herpes Simplex Virus Type 1 And Bovine Herpesvirus 1 Latency, Clinton J. Jones

School of Veterinary and Biomedical Sciences: Faculty Publications

A high percentage of the world’s population are infected with herpes simplex virus type 1 (HSV-1), and infection can cause a variety of disorders (35, 187). Recurrent ocular HSV-1 is the leading cause of infectious corneal blindness in industrialized nations (190). In a murine model, ocular infection induces autoimmune disorders, leading to corneal antigen destruction and stromal keratitis (275). HSV-1 infections also cause gastrointestinal disorders, esophageal disorders, and approximately 25% of the genital herpes infections (67, 158). HSV-1 infections can cause sporadic encephalitis, but this is relatively rare compared to other diseases resulting from infection. Further evidence for its involvement …

Characterization Of Protein Secretion In Mycobacterium Leprae Using Phoa Fusions In Escherichia Coli And Mycobacterium Smegmatis, Marina Noemi Torrero Jan 2003

Characterization Of Protein Secretion In Mycobacterium Leprae Using Phoa Fusions In Escherichia Coli And Mycobacterium Smegmatis, Marina Noemi Torrero

LSU Doctoral Dissertations

Complete sequencing and annotation of the M. leprae genome has provided new information related to proteins constituting its hypothetical proteome. Since M. leprae can not be grown in vitro, novel approaches are needed to determine which proteins are expressed during infection and whether these proteins are related to pathogenesis. Secreted proteins represent a distinct group of protein with respect to their structure and function, contribution to virulence and are of particular importance for vaccine development because they are often immunogenic and have the potential to be recognized early in infection. The objectives of this study were: 1) to identify putatively …
