Investigation Into Bacterial Impairment Of Greene And Polk County Water Systems, John C. Kincaid
Investigation Into Bacterial Impairment Of Greene And Polk County Water Systems, John C. Kincaid
MSU Graduate Theses
Bacterial impairment of water systems is a major issue facing mankind. Bacteria that are introduced into a system have the potential to cause harmful diseases to wildlife and humans. In Greene and Polk counties, many water systems have become bacterially impaired over the years. Despite this, little is known about the contamination of known harmful bacteria in this region. To address this issue, I investigated the presence of known human pathogens across water systems in these two counties, many of which have displayed high levels of E. coli and fecal indicator microorganisms over many years. I used a high-throughput sequencing …
Molecular Detection Of Pathogenic Leptospira Throughout The Caribbean, Zamara R. Garcia Truitt
Molecular Detection Of Pathogenic Leptospira Throughout The Caribbean, Zamara R. Garcia Truitt
Biology Theses
Leptospirosis is a common widespread zoonotic disease found throughout the Caribbean. The infection is produced by a pathogenic Leptospira species found in tropical and subtropical regions. The severity of the disease ranges from a mild asymptomatic infection to death. Leptospirosis is a neglected tropical disease due to the lack of public awareness and health approaches. Therefore, misdiagnosis is common because the symptoms are similar to that of other tropical endemic diseases. The aim of the study was to determine the presence of pathogenic Leptospira in water samples collected from Puerto Rico and Trinidad. Sixty-four environmental water samples were collected throughout …
Improved Methods For The Quantification Of Viable Ascaris Suum And Application To Biosolids, Tanner Keyzers
Improved Methods For The Quantification Of Viable Ascaris Suum And Application To Biosolids, Tanner Keyzers
Dissertations, Master's Theses and Master's Reports
The current method for detection of Ascaris ova in biosolids and wastewater has several drawbacks including being labor and time intensive as well as being difficult to quantify viable ova that have larvated during treatment. The goal of this thesis was to improve several methods for the detection and quantification of Ascaris ova during long term-storage of biosolids including improvement of quantifying viable ova using a heat and bleach treatment to promote movement of larvae inside of ova, and comparison of the traditional microscopic method with qPCR and PMA-qPCR to prevent the false-positive results. Improved methods to promote movement of …
