Lack Of Delayed-Type Hypersensitivity In Striped Bass (Morone Saxatilis), Jessica Shannon Miller
Lack Of Delayed-Type Hypersensitivity In Striped Bass (Morone Saxatilis), Jessica Shannon Miller
Biological Sciences Theses & Dissertations
Mycobacteriosis is a fatal disease in fishes caused by acid-fast bacteria in the genus Mycobacterium. This disease impacts aquaculture, aquariums, and wild fishes. Unfortunately, there are currently no non-lethal diagnostic tests for mycobacterial infection in fishes. Type IV delayed type hypersensitivity (DTH) responses in vivo and in vitro are currently used for the non-lethal detection of mycobacterial infections in humans and in animals; however, there is little information available on DTH responses in fishes. In this work, we examine in vivo DTH response in Striped Bass (Morone saxatilis), an important U.S. Eastern seaboard fish species, experimentally …
Evidence For Disease Mediated Extinction: Correlation Between An Introduced Pathogen And Extinction Of Rattus Macleari On Christmas Island, Kelly B. Wyatt
Evidence For Disease Mediated Extinction: Correlation Between An Introduced Pathogen And Extinction Of Rattus Macleari On Christmas Island, Kelly B. Wyatt
Biological Sciences Theses & Dissertations
The Durham Collection and the Cambridge and Oxford University Museums provided the materials to investigate the possibility that the extinction of indigenous rats of Christmas Island was a result of disease introduced by infected ship rats (R. rattus) in 1899. The collections of H.E. Durham in 1901-1902 reveal that R. macleari was present on Christmas Island up to then and includes specimens of R. rattus together with specimens that exhibit characteristics of both R. rattus and R. macleari. Durham's notes indicate both R. rattus and R. macleari specimens were heavily infected with trypanosomes at the time of collection. In …
The Ecological Ramifications Of Disease And Density In The Caribbean Spiny Lobster, Panulirus Argus, Donald C. Behringer Jr.
The Ecological Ramifications Of Disease And Density In The Caribbean Spiny Lobster, Panulirus Argus, Donald C. Behringer Jr.
Biological Sciences Theses & Dissertations
In 1999, I discovered the first virus known to be pathogenic to any species of lobster. HLV-PA is a pathogenic herpes-like virus that infects juvenile Caribbean spiny lobster, Panulirus argus, in the waters off south Florida (USA), and it alters the behavior and ecology of this species in fundamental ways. Gross signs of HLV-PA infection are lethargy, morbidity, cessation of molting, and discolored, “milky” hemolymph that does not clot. HLV-PA infects the hemocytes of host lobsters, specifically the hyalinocytes and semi-granulocytes, but not the granulocytes. When hemolymph from infected donors was injected into healthy juvenile lobsters, 90% of the …
Enzyme Linked Immunosorbent Assay For Anatid Herpesvirus, Margaret Anne Lewis
Enzyme Linked Immunosorbent Assay For Anatid Herpesvirus, Margaret Anne Lewis
Biological Sciences Theses & Dissertations
Duck plague virus causes a hemorrhagic disease affecting the family Anatidae, resulting in 60-80% mortality in captive flocks. Plaque and neutralization assays for Anatid herpesvirus (AHV) require 5-10 days for completion and are restricted by the seasonal availability of fertile duck eggs. The enzyme linked innnunosorbent assay (ELISA) is rapid and specific and avoids the use of living cells. The Holland strain of AHV was grown on duck embryo fibroblasts and purified by banding on CsCl gradients. The resulting virus was used to raise antisera in prebled New Zealand white male rabbits. Antibody production was confirmed in double diffusion plates …
Duck Plague Virus An Investigation Of Cytopathic Effects, In-Vitro Host Range, And Inhibition By Phosphonoacetic Acid, Ronald Attanasio
Duck Plague Virus An Investigation Of Cytopathic Effects, In-Vitro Host Range, And Inhibition By Phosphonoacetic Acid, Ronald Attanasio
Biological Sciences Theses & Dissertations
Duck plague is a hemorrhagic, necrotic disease found exclusively in the order Anseriformes, family Anatidae (ducks, geese, swans). The etiologic agent has been reported to be a herpes-like virus. The Holland strain of duck plague was found to induce cytopathic effects in cell culture (perinuclear vacuolation followed by lysis). A simple reproducible plaque assay for quantitating the virus was developed. Under conditions of the plaque assay, one-hit kinetics were observed. The host range of duck plague virus in cell culture was found to include the order Galliformes, family Phasianidae (pheasants, quails and partridges). Duck plague virus-induced cell culture cytopathic effects …
The Pathophysiology Of Acute Venous Occlusion, Lewis H. Curd Jr.
The Pathophysiology Of Acute Venous Occlusion, Lewis H. Curd Jr.
Biological Sciences Theses & Dissertations
Large artery, pedal small vein, femoral vein and central venous pressures and extremity volume changes were recorded in mongrel dogs in which the hindlimb was perfused at a constant flow. Arterial, pedal venous and femoral venous blood gases were drawn and analyzed for measurements of arterio-venous O2 and CO2 differences. Paw and thigh resistances were calculated. Measurements were repeated following ligation of the iliac and femoral veins, alpha receptor blockade (dibenzyline), and dilation with Vasodilan. Results indicate that ligation of extremity veins results in an active ·increase in total limb resistance below the ligation, an increase in the …
