Testing The In Vitro Effectiveness Of Protease Inhibitors Against Histomonas Meleagridis, Evy Belle Hafer
Testing The In Vitro Effectiveness Of Protease Inhibitors Against Histomonas Meleagridis, Evy Belle Hafer
Animal Science Undergraduate Honors Theses
Histomonas meleagridis is a protozoal parasite able to exist in a flagellated or amoeboid form that infects gallinaceous birds, particularly turkeys, and causes significant mortality. There is currently no effective treatment for this disease. The purpose of this study was to assess the anti-histomonal activity of commercially available protease inhibitors, leupeptin, bestatin, and antipain, using an established in vitro model. Three protease inhibitors, leupeptin, bestatin, and antipain, were evaluated across five assays. Treatment groups included: 1) non-treated control, 2) leupeptin 100 µM, 3) bestatin hydrochloride 100 µM, and 4) antipain dihydrochloride 100 µM. Histomonads were enumerated using a hemocytometer after …
Determination Of Ownership Practices And Cytauxzoon Felis Prevalence In Domestic Felines Of Northwest Arkansas, Daniella M. Duran
Determination Of Ownership Practices And Cytauxzoon Felis Prevalence In Domestic Felines Of Northwest Arkansas, Daniella M. Duran
Animal Science Undergraduate Honors Theses
Cytauxzoon felis is a protozoan pathogen that causes the infectious disease, cytauxzoonosis in wild and domestic felines. The natural host of this pathogen is the bobcat (Lynx rufus), which is why this disease is also commonly referred to as “bobcat fever”. The C. felis pathogen infects wild and domestic cats upon transmission by infected ticks. Amblyomma americanum, also known as the Lone Star tick, the primary transmission vector for C. felis. This tick species is largely populated throughout the state of Arkansas, making C. felis a large threat to wild and domestic felines in these areas. Cytauxzoonosis is commonly thought …
The Efficacy Of Extended-Release Eprinomectin For The Reduction Of Horn Flies, Face Flies, And Fecal Egg Counts Of Parasitic Nematodes In Replacement Beef Heifers, Sophia F. Landers
The Efficacy Of Extended-Release Eprinomectin For The Reduction Of Horn Flies, Face Flies, And Fecal Egg Counts Of Parasitic Nematodes In Replacement Beef Heifers, Sophia F. Landers
Animal Science Undergraduate Honors Theses
The purpose of this study was to evaluate the efficacy of extended-release eprinomectin against horn flies, face flies, and fecal egg counts of parasitic nematodes in crossbreed replacement beef heifers. Fifty-four heifers were randomly placed into three treatment groups (N=18 heifers/treatment). Group 1 was administered the labeled dosage of extended-release eprinomectin on day 0. Group 2 acted as the negative control. Group 3 received the anthelmintic injection once a quarter of the heifers in the group reached the threshold treatment level for horn flies (N=200 flies/animal; day 41). Nematode infections were measured via fecal egg counts while horn and face …
Geospatial Analysis Of Rickettsial Species, Amy Frank
Geospatial Analysis Of Rickettsial Species, Amy Frank
Animal Science Undergraduate Honors Theses
Rickettsia species are obligate intracellular, arthropod-borne bacteria with a potential to cause multiple diseases including Rocky Mountain spotted fever (RMSF). Fleas, mites, and ticks serve as vectors for Rickettsia, but ticks are the primary vector of interest. RMSF and other rickettsial diseases have continued to gain importance in both human and veterinary medicine as RMSF is the most common tick-borne disease within the United States according to the Lyme and Tick-Borne Disease Research Center. A statewide citizen science project was utilized to determine the prevalence of Spotted Fever Group (SFG) Rickettsia in Arkansas. This project yielded results in 64 …
