Highly-pathogenic avian influenza virus (HPAIV H5N1) poses risks to wild birds, poultry, and humans. Personnel with the United States Department of Agriculture-Animal Plant Health Inspection Service-Wildlife Services, state, and tribal wildlife agencies collected 168,940 samples from migratory birds from 2007 to 2009 to test for presence of HPAIV H5N1. No HPAIV was found, but other subtypes were discovered, including H5 and H7. I estimated prevalence of avian influenza virus by flyway and found prevalence was lowest each year in the Atlantic Flyway (6.7%–8.3%), highest in the Pacific Flyway in 2007 (13.3%) and 2008 (13.4%), and highest in the Mississippi Flyway …

Analysis And Interpretation Of Factors Leading To Increased Aids Prevalence In Sub-Saharan Africa, William Kalhorn
Department of Environmental Studies: Undergraduate Student Theses
My thesis research project focuses on the major factors that are contributing to the worst disease epidemic on the planet today. I have aimed to determine what may be some of the most important factors contributing to highly variable difference in HIV/AIDS prevalence rates are among the regions of East, West, and South Africa. The HIV/AIDS epidemic has been growing and expanding to new areas of the world since the first case arose in 1959 in what is now called Kinshasa, Congo (Avert, 2011). The AIDS/HIV epidemic is believed to have originated on the African continent, and this is where …

Inactivation of the Staphylococcus aureus tricarboxylic acid (TCA) cycle delays the resolution of cutaneous ulcers in a mouse soft tissue infection model. In this study, it was observed that cutaneous lesions in mice infected with wild-type or isogenic aconitase mutant S. aureus strains contained comparable inflammatory infiltrates, suggesting the delayed resolution was independent of the recruitment of immune cells. These observations led us to hypothesize that staphylococcal metabolism can modulate the host immune response. Using an in vitro model system involving RAW 264.7 cells, the authors observed that cells cultured with S. aureus aconitase mutant strains produced significantly lower amounts …
