Brugia Phangi: Effects Of Third Stage Larvae Es Immunization On Early Migration And Parasite Establishment In Mongolian Gerbils (Meriones Unguiculatus), Ginger Ann Robertson
LSU Master's Theses
Brugia infections occur via the bite of an infected mosquito. Third stage infective larvae (L3) deposited on the skin during feeding migrate into the bite wound, through skin and into the lymphatic system. It is hypothesized that L3 excretory/secretory products (ES) are important in this initial phase of the infection. A model for these early migrations has been established by inoculating L3s into the dermis (ID) of the permissive gerbil host. In this model, most L3s injected ID in the louer hind limb travel to the popliteal lymph node by 3 days post infection. Adult parasites are located primarily in …
Effect Of Vaccination Of Goats With H-Gal-Gp And H11 Antigens From Intestinal Membrane Cells Of Haemonchus Contortus, Donya Dupree Olcott
Effect Of Vaccination Of Goats With H-Gal-Gp And H11 Antigens From Intestinal Membrane Cells Of Haemonchus Contortus, Donya Dupree Olcott
LSU Master's Theses
Extracts of adult Haemonchus contortus were purified and used as a vaccine against the blood feeding parasite in goats as previously studied in sheep. The proteins used were H11 and H-gal-GP, hidden gut antigens from the microvillar membrane of the gut of the worm and combined with Quil A as adjuvant, then administered to a group of goats kept on concrete then artificially infected with H. contortus. The control group received Quil A injections and also infected. This study was performed to analyze the effects of the H11/H-gal-GP vaccine when given to goats as compared to sheep. The trial showed …
Characterizing Salmonella Fecal Shedding Among Racehorses In Louisiana, Anna Marie Chapman
Characterizing Salmonella Fecal Shedding Among Racehorses In Louisiana, Anna Marie Chapman
LSU Master's Theses
Salmonella is an important intestinal pathogen in horses capable of infecting populations without demonstrating clinical illness. This study was performed to determine the prevalence of Salmonella fecal shedding among racehorses in Louisiana. Three serial fecal samples were collected from 429 Thoroughbred horses housed at four racetracks. Feces were tested for Salmonella by microbiologic culture with selective primary enrichment and delayed secondary enrichment (DSE). Samples were also evaluated for the presence of Salmonella by polymerase chain reaction (PCR) using genus-specific oligonucleotide primers. A total of 7 (1.6%) horses were positive for Salmonella by either primary bacterial culture or DSE and an …
