Item Associations Between Vibrio and the Planktonic Community Throughout Tampa Bay(Department of Biology, College of Natural and Health Sciences, The University of Tampa, 2019) Johnson, Heather; Dr. Bridgette Froeschke; Dr. Rebecca WaggettVibrio is a genus of bacteria whose species naturally inhabit warm, marine waters throughout the world. Many of these species are pathogenic to humans, which makes predicting outbreaks of vital importance. Considerable information is still being discovered about Vibrio ecology, therefore additional studies of Vibrio in the marine environment are necessary. Previous relationships between Vibrio species, the planktonic community, and environmental factors have been described, but these relationships have not been explored in Tampa Bay. Zooplankton tows were performed at six different locations in Tampa Bay. Three sites were located in the inner bay, while three were closer to the Gulf of Mexico. Whole water samples and environmental parameters were also collected from each site. Zooplankton samples were separated into two classes: copepods and copepod nauplii and resuspended in sterile saline. Whole water samples were diluted to 101, 10mL, and 20mL. Zooplankton and water samples were vacuum filtered, and the filter paper plated on Thiosulfate-Citrate-Bile-Sucrose (TCBS) agar plates. The plates were incubated at 37 C for 24 hours and assessed for growth. Associations between Vibrio and the planktonic community, as well as patterns in environmental factors provide valuable insight to the bacterial community of Tampa Bay.Item Comparison of Antibiotic Susceptibility of Bacterial Communities on Cell Phones Belonging to Health Care Workers and Non-Health Care Workers(College of Natural and Health Sciences, The University of Tampa, 2016) Matt Guillemette, Zachary Rivera; Eric FreundtThe frequent use of cell phones inside of health care facilities produces a risk of contamination of the phones with potentially pathogenic bacteria. The elevated use of antibiotics within these health care facilities may also contribute to heightened levels of antibiotic resistant strains on these devices. To assess this, bacterial samples were collected from health care workers’ and non-health care workers’ cell phones. The bacterial isolates were assessed for antibiotic resistance via the Kirby-Bauer method. Eleven out of nineteen of the bacterial isolates from the health care workers cell phones displayed resistance to at least one antibiotic. According to our study, the lower amount of resistance of the bacteria isolated from the health care worker samples compared to the non-health care worker samples leads us to conclude that there is not a higher prevalence of antibiotic resistant bacteria on health care workers’ phones.
