Molecular Detection Of Human And Dog Fecal Pollution In Pensacola, Florida, Logan Mccullers, Jodel Nicholas, Dave Bachoon Mar 2024

Molecular Detection Of Human And Dog Fecal Pollution In Pensacola, Florida, Logan Mccullers, Jodel Nicholas, Dave Bachoon

Graduate Research Showcase

Pensacola, Florida (USA), has a thriving coastal community that depends on its coastal areas for recreation, shellfish harvesting, and fisheries. However, increasing levels of fecal pollution pose a potential threat to the water quality of these coastal systems. Identifying the source and abundance of contaminants in these environments is critical to controlling fecal pollution in these areas. This study aimed to use Microbial Source Tracking techniques to determine the source of pollution in five sites (Bayou Texar Lower, Willard Norris Road Creek, Clear Creek Boat Ramp @ 87, Quinette River Boat Ramp and Pensacola Bay Bridge) in the Pensacola area. …

The Influence Of Environmental Parameters On Gordonia Terrae - Specific Bacteriophage Abundance And Diversity, Gt M. Moore, Uqueen C. Wheeler, Indiren Pillay Jan 2024

The Influence Of Environmental Parameters On Gordonia Terrae - Specific Bacteriophage Abundance And Diversity, Gt M. Moore, Uqueen C. Wheeler, Indiren Pillay

Graduate Research Showcase

Bacteriophages are viruses that infect a wide variety of host bacteria with some strains having medical and industrial significance. These highly abundant and genetically bacterial viruses constitute a large amount of unexplored genetic information. Because bacteriophages are highly specific, they can be used therapeutically to combat bacterial infections by selecting a phage to target and kill harmful bacteria. Thus, phage therapy is currently being explored to aid in the fight against antibiotic resistance. Actinobacteriophages are viruses that specifically infect Phylum Actinobacteria hosts including the environmentally abundant Gordonia terrae. Some species of Gordonia, including G. terrae, have also …


The Presence Of Pathogenic Leptospira In San Juan Bay Estuaries And Its Relationship To Fecal Pollution Sources, Jodel M. Nicholas, Dave Bachoon Dr. Jan 2024

The Presence Of Pathogenic Leptospira In San Juan Bay Estuaries And Its Relationship To Fecal Pollution Sources, Jodel M. Nicholas, Dave Bachoon Dr.

Graduate Research Showcase

The northern coastal zones of Puerto Rico, including the San Juan Bay and Rio Grande de Loiza watersheds, are increasingly becoming focal points of environmental concern due to wastewater originating from human activity. This runoff, which consists of effluents from sewage treatment, septic tanks, and animal husbandry, enters coastal lagoons and estuaries, posing critical threats to these vital ecosystems. This study aims to determine the presence of Leptospira in over 100 samples from 16 sub-basins over 2 years as well as identify the major sources of fecal pollution using molecular source tracking techniques. End point PCR assays for Leptospira (LipL32), …
