Clinical And Subclinical Mastitis Causing Pathogens In Tennessee Dairy Cattle, Michelle Marie Untch
Clinical And Subclinical Mastitis Causing Pathogens In Tennessee Dairy Cattle, Michelle Marie Untch
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
Milk quality impacts the producers and consumers. Higher milk quality leads to a longer shelf life, improved cheese making ability, and improved taste. Milk quality can be severely impacted by intramammary infections which can result in mastitis. Identifying the common mastitis causing pathogens in milk samples collected from subclinical and clinical mastitis cases can assist the producer in managing mastitis. This can lead to improved milk quality, improved cow health, and reduced need for antibiotics to treat mastitis. This study investigates the prevalence of bacteria causing intramammary infection in dairy cattle of Tennessee. Milk samples were collected from 9 farms …

Histomonas meleagridis is a protozoan parasite of avians and is the causative agent in Histomonosis, commonly known as Blackhead Disease. Current methods for diagnosing the presence of H. meleagridis are limited to parasite culture or Polymerase Chain Reaction (PCR) to amplify target DNA. This project aims to develop an enzyme-linked immunosorbent assay (ELISA) for faster and more sensitive diagnosis of Histomonas infections. Cultures of H. meleagridis parasites were purified, and surface antigens were extracted using a spectrum of chemical solutions. The various antigen solutions were subjected to an ELISA, with serum from birds immunized for H. meleagridis as positive controls. …

The U.S. organic dairy industry has experienced significant growth in recent years: over 10% growth annually since 2009 and 14.5% from 2010 to 2011; total market share is approximately 5% in the United States. The USDA places certain requirements on diary products that are certified organic, some of which are aimed at grazing practices. One challenge farmers must overcome to comply is keeping the cows in optimum conditions in a free-range grazing scenario; poor conditions such as excessive heat can decrease milk production and pose an economic burden on the dairy. The proposed system intends to control environmental conditions for …
Design Of An Underwater Video And Gps Mapping System For The Exploration Of Streambed Aquatic Populations, William Barbour
Design Of An Underwater Video And Gps Mapping System For The Exploration Of Streambed Aquatic Populations, William Barbour
EURēCA: Exhibition of Undergraduate Research and Creative Achievement
This design project was initiated due to the need for an underwater video mapping system optimized for exploration along the streambed or riverbed and under rocks. Such a system would be used for population mapping of fish and other aquatic species. The system also needed to incorporate global positioning system data with the visual data. The current prototype successfully fulfills the requirements for underwater practicality and visual and GPS data collection. It incorporates a compact waterproof camera with Sony lens, two Fenix high-intensity waterproof flashlights for illumination, a handheld DVR for recording video, and a Garmin 60CSx GPS unit. The …
