Epithelial Responses To Porphyromonas Gingivalis In The Community Context., Zackary Ray Fitzsimonds 2020 University of Louisville

Epithelial Responses To Porphyromonas Gingivalis In The Community Context., Zackary Ray Fitzsimonds

Electronic Theses and Dissertations

Porphyromonas gingivalis, a keystone pathogen for periodontal disease, initiates a complex molecular dialogue with gingival epithelial cells, leading ultimately to disruption of host signaling pathways. Dysbiotic host responses are also thought to contribute to the initiation and progression of oral squamous cell carcinomas. Recently, the homeostatic commensal Streptococcus gordonii has been shown to antagonize P. gingivalis-induced epithelial cell signaling events in host cells, such as proliferation and migration. The aim of this study was to characterize pathways that P. gingivalis targets to disturb host signaling, with a specific focus on pathways that S. gordonii can restore to homeostatic …

The Emerging Oral Pathogen, Filifactor Alocis, Disrupts Neutrophil Functions To Enhance Survival And Dysregulate Inflammation., Irina Miralda Molina

Electronic Theses and Dissertations

Periodontitis is an irreversible, chronic inflammatory disease where pathogenic microbial communities accumulate in the gingival crevice. Advances in culture-independent techniques have facilitated the identification of new bacterial species in periodontal lesions, such as the Gram-positive anaerobe, Filifactor alocis. Neutrophils are a major component of the innate host response, and the outcome of their interaction with F. alocis may be a determinant of oral health status. While neutrophil functions typically protect the host against periodontal disease, oral pathogens have adapted to evade or disarm neutrophil microbicidal functions while promoting mechanisms that drive inflammation, which also provides a source of nutrients …

Oral streptococci are major residents in the oral cavity, with S. mutans the primary cause of dental caries. Growth and biofilm formation have been shown to be enhanced upon exposure to traditional cigarette smoke in vitro. In this study, we analyzed the effects of e-cig vapor on growth …


The Role Of Manganese In Streptococcus Sanguinis, Tanya M. Puccio 2020 Virginia Commonwealth University

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 …
