Identification Of Genes That Determine Fitness, Virulence, And Disease Outcomes In Mastitis Associated Eschericia Coli, Michael Andrew Olson Dec 2020

Identification Of Genes That Determine Fitness, Virulence, And Disease Outcomes In Mastitis Associated Eschericia Coli, Michael Andrew Olson

Theses and Dissertations

Escherichia coli is an incredibly diverse group of bacteria that consist of both commensal and pathogenic strains that cause disease in a wide variety of tissues in many different animals. The current dogma, based on years of extensive molecular and genetic studies, is that individual strains have adapted to specific environments through acquisition of specific genes or come from lineages that are particularly suited to a unique tissue or host. However, mastitis-associated E. coli (MAEC) have thus far resisted such descriptions. The fitness and virulence factors of MAEC are poorly understood and molecular tools are rarely applied. This dissertation reports …


Staphylococcus Aureus Metal Acquisition In Milk And Mammary Gland Tissue, Shalee Killpack Carlson Mar 2020

Staphylococcus Aureus Metal Acquisition In Milk And Mammary Gland Tissue, Shalee Killpack Carlson

Theses and Dissertations

Mastitis resulting from mammary gland infection is a common and painful disease associated with lactation. In addition to the impact on human and animal health, mastitis causes substantial economic losses in the dairy industry. Staphylococcus aureus is a frequent cause of mastitis worldwide. Despite significant progress in understanding S. aureus pathogenesis in general, much remains to be learned regarding virulence factors relevant in the context of mastitis. In mammary gland infections, it is not fully understood which metal acquisition systems are required for S. aureus survival. To help understand molecular mechanisms by which S. aureus might acquire essential metals, such …
