Factors Influencing Diarrheal Pathogen Presence In Tubewells Of Bangladesh, Kati Anne Ayers
Factors Influencing Diarrheal Pathogen Presence In Tubewells Of Bangladesh, Kati Anne Ayers
Masters Theses
Diarrheal disease pathogens remain a major concern in developing countries as rotavirus is the leading cause of hospitalization of young children worldwide. A recent study has shown shallow groundwater in rural Bangladesh to be contaminated with bacterial and viral pathogens, but found no correlation between rotavirus and any fecal indicator or environmental parameter during the monsoon season of July, 2009. The objectives of this thesis were to examine the non-relationship between pathogens and fecal indicators, as well as to improve the understanding of the seasonal transport of viral pathogens, especially rotavirus, in shallow, sandy aquifers of Bangladesh. This was achieved …

Doctoral Dissertations
The disseration presented below is the summation of research into the potential roles of microbial communities associated with aquifers of Bangladesh contaminated with naturally occuring arsenic. These investigations also included experimental microcosm experiments to assess the role of nutrients supplementation of complex carbon sources (molasses), and inorganic sulfate (MgSO4), on both the solubility of arsenic to determine the feasibility of this method for the goal of performing in situ bioremediation. Community structure and functional gene profiling was performed on all samples, as well as detection of community shifts following amendments predicted to encourage the growth of sulfate reducting microorganisms (SRM). …
