Assessment And Prevention Of Bacterial Regrowth In Stored Household Water In Eastern Coastal Madagascar, Lauren Judah
Assessment And Prevention Of Bacterial Regrowth In Stored Household Water In Eastern Coastal Madagascar, Lauren Judah
USF Tampa Graduate Theses and Dissertations
As of 2020, diarrheal diseases were the leading cause of death in Madagascar. A major cause of diarrheal illness is contaminated water, and one crucial aspect of preventing contaminated water is safe household storage. Bacterial regrowth between point-of-collection and household storage has been well established in literature. A frequently implicated source of regrowth is the storage container’s biofilm, which is a community of varying bacteria enclosed in a “slimy” extracellular polymeric substance that forms on surfaces in wet environments and anchors bacteria to those surfaces. The overall goal of this thesis was to quantify and control bacterial regrowth in household …
Identification Of Pneumococcal Membrane Proteins Involved In Colonization/Biofilm Formation And Cognate Host Cellular Receptors, Yoonsung Hu
Theses and Dissertations
Colonization is prerequisite for infection and transmission of Streptococcus pneumoniae, or pneumococcus. Currently available pneumococcal conjugate and pneumococcal polysaccharide vaccines can provide protection against a limited number of capsular serotypes. Implementation of vaccines has decreased the frequency of invasive pneumococcal disease and their colonization rates, but only in a serotype-dependent manner. This has led to serotype replacement in pneumococcal ecology and increased invasive disease caused by non-vaccine serotypes. Development of conserved protein-based vaccine that can provide protection against all pneumococcal serotypes is needed. Numerous surface proteins are conserved in all serotypes, and some are known to be involved in …

Development Of Zafirlukast Derivatives Active Against Porphyromonas Gingivalis, Kaitlind C. Howard
Theses and Dissertations--Pharmacy
Periodontal diseases are inflammatory diseases that can lead to damage of the soft tissue and bone supporting the teeth. Gingivitis is the reversible early stage of gum disease, which consist of gums that bleed when brushing or flossing teeth. When left untreated, the preventable but irreversible late stage of periodontal disease, periodontitis, can lead teeth to loosen or even fall out. Oral bacterial species, such as the Gram-negative anaerobic pathogen Porphyromonas gingivalis trigger these inflammatory diseases through oral dysbiosis. P. gingivalis is a keystone pathogen, meaning that the damage caused by P. gingivalis is not proportional to its abundance. Treatment …
