The Role Of Manganese In Streptococcus Sanguinis, Tanya M. Puccio
The Role Of Manganese In Streptococcus Sanguinis, Tanya M. Puccio
Theses and Dissertations
Streptococcus sanguinis is primarily associated with oral health as a commensal bacterium. As an opportunistic pathogen, S. sanguinis is capable of colonizing heart valve vegetations, leading to the disease infective endocarditis. Previous studies from our lab have identified the high-affinity manganese transporter SsaACB as important for endocarditis virulence. The impact that manganese depletion has on S. sanguinis had never been evaluated and a secondary manganese transporter has not been identified. Thus, we employed the use of a fermentor to control large-scale growth over time and depleted manganese in an ΔssaACB mutant using a metal chelator, EDTA. The changes in …

Development Of A Screening Assay For Type Iii Secretion System Inhibitors And High Throughput Screening Campaign Of Inhibitors Of Prp Of Staphylococcus Aureus, Heather A. Pendergrass
Theses and Dissertations
Antibiotics inhibit the growth or survival of bacteria by targeting their essential functions.1 Due to weaknesses in traditional antibiotics and the increasing prevalence of antibiotic resistance genes, virulence factors are being targeted for therapeutic treatment of bacterial infection.2 We have developed an assay to quantify and observe type III secretion system (T3SS) activity. The type III secretion system (T3SS) is a virulence factor present in some Gram-negative pathogens including enteropathogenic and enterohemorrhagic E. coli (EPEC and EHEC, respectively),3 and others.4–9 The T3SS between EPEC and EHEC are highly conserved and share over 90% sequence identity with …
