Genotypes And Phenotypes Of Staphylococci On Selected Dairy Farms In Vermont, Robert Mugabi
Genotypes And Phenotypes Of Staphylococci On Selected Dairy Farms In Vermont, Robert Mugabi
Graduate College Dissertations and Theses
The genus Staphylococcus contains at least 47 species and 23 subspecies. Bacteria in this genus are ubiquitous; many are commensals on human and animal skin and can be opportunistic pathogens. In dairy cattle, staphylococci are the leading cause of intramammary infections (IMI) and mastitis. Mastitis is the inflammation of the mammary gland, and is one of the leading infectious diseases causing production losses in the dairy industry. Based on the ability to clot blood plasma in vitro, members of the genus can be divided into two groups: coagulase positive staphylococci (CPS) and coagulase negative staphylococci (CNS). In the dairy industry, …
Methylation Controlled J Protein Is A Master Regulator Of Mitochondrial Metabolism, Devin Pierre Champagne
Methylation Controlled J Protein Is A Master Regulator Of Mitochondrial Metabolism, Devin Pierre Champagne
Graduate College Dissertations and Theses
Methylation controlled J protein (MCJ) is a negative regulator of mitochondrial metabolism that has a substantial impact on overall cell metabolism and function. MCJ is highly expressed by naïve CD8+ T cells, however its role in their immune effector functions was unknown. In this dissertation, it will be demonstrated that MCJ restricts the mitochondrial metabolism of CD8+ T cells, in part by reducing respiratory supercomplex formation. MCJ deficiency enhances the immune effector functions and memory responses of CD8+ T cells in a mitochondrial ATP dependent manner. As a consequence, protection to influenza virus infection is substantially improved. Reduced expression of …
21st Century Approaches To Addressing Childhood Diarrhea In Low And Middle-Income Countries: Zinc As A Cornerstone Of New Prevention Strategies, Elizabeth Ross Colgate
21st Century Approaches To Addressing Childhood Diarrhea In Low And Middle-Income Countries: Zinc As A Cornerstone Of New Prevention Strategies, Elizabeth Ross Colgate
Graduate College Dissertations and Theses
During the 20th century, significant strides were made in curtailing the burden of childhood diarrhea, including advances in vaccine research, the advent of antibiotics, improved water and sanitation, and expanded access to health information across the globe. Despite this progress, today diarrhea ranks second only to pneumonia as a leading cause of mortality in children under five years, with a disproportionate burden of 90% of diarrheal deaths in South Asia and Sub-Saharan Africa. Additionally, substantial morbidity due to diarrhea persists in young children, with more than 45 million disability-adjusted life years (DALYs) lost due to diarrhea in 2015. Long-term consequences …
Methods To Identify And Develop Drugs For Cryptosporidiosis, Rajiv Satish Jumani
Methods To Identify And Develop Drugs For Cryptosporidiosis, Rajiv Satish Jumani
Graduate College Dissertations and Theses
Cryptosporidiosis is a common diarrheal disease caused by intestinal infection with the apicomplexan parasite Cryptosporidium, in humans usually either with C. hominis or C. parvum. Unfortunately, given a large burden of disease in children and immunocompromised people like AIDS patients, the only currently approved treatment, nitazoxanide, is unreliable for these patient populations. To address the urgent need for new drugs for the most vulnerable populations, large phenotypic screening efforts have been established to identify anti-Cryptosporidium growth inhibitors in vitro (hits). However, in the absence of a gold standard drug, the in vitro and in vivo characteristics that should be used …
