Abstract/Description
Vibrio vulnificus is a marine pathogen of human health concern, capable of causing potentially fatal wound infections in a select group of the population. Previous studies have indicated this species’ strong negative correlation with salinity, not typically found above 30 ppt. This study assessed the ability of V. vulnificus to become Viable But Nonculturable in response to elevated salinity (35 ppt) as well as investigated novel methods for confirming their entrance into this state.

Show moreVibrio vulnificus is a marine pathogen of human health concern, capable of causing potentially fatal wound infections in a select group of the population. Previous studies have indicated this species’ strong negative correlation with salinity, not typically found above 30 ppt. This study assessed the ability of V. vulnificus to become Viable But Nonculturable in response to elevated salinity (35 ppt) as well as investigated novel methods for confirming their entrance into this state. Results showed a complete loss of culturability in both Environmental and Clinical strains of this bacterium by 9 days after inoculation. Using a High Content Imager, it was determined that these pathogens were not dying (< 10%) in response to the treatment and were partially becoming cocci (≈35%). This study indicates the importance of understanding the impact environmental parameters have on this human pathogen, and what it means for reliably detecting them.

Does Water Hyacinth (Eichornia Crassipes) Compensate to Defoliation? Implications for Effective Biocontrol
Title
Does Water Hyacinth (Eichornia Crassipes) Compensate to Defoliation? Implications for Effective Biocontrol.
Creator
Soti, Pushpa G., Volin, John C., Florida Atlantic University
Abstract/Description
The aim of this study was to determine the effects of nutrient supply and artificial defoliation on the growth rate of water hyacinth. The plants were subjected to two levels of nutrient (high and low) and three levels (0%, 10% and 80%) of defoliation treatment. The effect of the nutrient and repeated defoliation treatments was detem1ined after six weeks. Ten percent defoliation did not show any significant difference from control plants in biomass allocation or relative growth rate (RGR) in...
Show moreThe aim of this study was to determine the effects of nutrient supply and artificial defoliation on the growth rate of water hyacinth. The plants were subjected to two levels of nutrient (high and low) and three levels (0%, 10% and 80%) of defoliation treatment. The effect of the nutrient and repeated defoliation treatments was detem1ined after six weeks. Ten percent defoliation did not show any significant difference from control plants in biomass allocation or relative growth rate (RGR) in either nutrient concentration, while 80% defoliation caused a significant decrease in the final RGR under high and low nutrient treatments. High nutrient treatment resulted in higher RGR and allocation to asexual reproduction, resulting in higher biomass accumulation compared to the low nutrient treatment, which had higher root growth and allocation to sexual reproduction. My data provide evidence that water hyacinth can fully compensate to low levels of defoliation.

Abstract/Description
Vibrio bacteria are emerging pathogens responsible for 80,000 illnesses and 100 deaths in the United States each year. Infections are directly linked to the marine environment and are acquired by consuming contaminated seafood or exposing wounds during aquatic activities. Florida has the highest national incidence of vibriosis, with 20% of its cases reported from the Indian River Lagoon region, a popular recreation destination.

Show moreVibrio bacteria are emerging pathogens responsible for 80,000 illnesses and 100 deaths in the United States each year. Infections are directly linked to the marine environment and are acquired by consuming contaminated seafood or exposing wounds during aquatic activities. Florida has the highest national incidence of vibriosis, with 20% of its cases reported from the Indian River Lagoon region, a popular recreation destination. This study utilized a combination of cultivation and molecular techniques to investigate the local distribution of V. vulnificus, V. parahaemolyticus and V. cholerae in this local waterway. The targeted species were found in an array of samples which may facilitate their transmission to humans. Overall, these bacteria were abundant in estuarine sediments (Vp: 2,439 CFU/g, Vv: 303 CFU/g, Vc: 176 CFU/g), on the sharp edges of oyster shells (Vp: 82 CFU/cm, Vv: 102 CFU/cm, Vc: 41 CFU/cm), and in the water column (Vp: 3.78 CFU/ml, Vv: 5.51 CFU/ml, Vc: 2.46 CFU/ml). Vibrio also pose a hazard to recreational anglers as they were recovered from fish (Vp: 61%, Vv: 55%, Vc: 30%), live bait shrimp (Vp: 80%, Vv: 37%, Vc: 0%) and hooks (Vp: 32%, Vv: 18%, Vc: 0%). Additionally, a molecular analysis of the V. vulnificus virulence revealed that the local population was dominated by disease-causing (vcgC) strains, which may explain why wound-related infections are common in this region. Vibrio occurrence varied both spatially and temporally due to their relationship with salinity and temperature. These bacteria exhibited a strong negative correlation with salinity, being particularly abundant near freshwater discharge locations. Due to Florida’s year-round warm climate, these species were found to be permanent members of the local microbial community. Seasonal peaks in abundance occurred between August and October, a period which corresponds with the warmest water temperatures as well as frequent rainfall. Predictive models were constructed based on these parameters to provide a better understanding of how, when and where Vibrio spp. may be encountered by humans. This information is important for both water management and healthcare initiatives, with an overall goal of improving local recreational safety.

The correlations between OSTDS sites and the pollution of the surface water bodies in Broward County.
Creator
Rocher, Yvel, Bloetscher, Frederick, Florida Atlantic University, College of Engineering and Computer Science, Department of Civil, Environmental and Geomatics Engineering
Abstract/Description
Sampling data of many surface water bodies in Broward County tend to reveal abnormal levels of bacterial concentrations for total coliform, Escherichia coli and Enterococcus. Given the presence of septic systems in geohydrologically sensitive areas throughout the County, several studies (Morin 2005 and Bocca 2007) suggested a correlation in the high bacterial densities and the septic sites.

Abstract/Description
Fecal samples were obtained from guenons in Gombe National Park utilizing noninvasive, opportunistic sampling techniques. Samples were then examined for the presence of gastrointestinal parasites using chlorazol black stain, Lugol’s iodine staining, as well as concentration via fecal flotation with Sheather’s sugar solution. Results were analyzed using SPSS (IBM corp), and compared to other forested regions in Africa to determine whether hybridization influences parasite prevalence of these...
Show moreFecal samples were obtained from guenons in Gombe National Park utilizing noninvasive, opportunistic sampling techniques. Samples were then examined for the presence of gastrointestinal parasites using chlorazol black stain, Lugol’s iodine staining, as well as concentration via fecal flotation with Sheather’s sugar solution. Results were analyzed using SPSS (IBM corp), and compared to other forested regions in Africa to determine whether hybridization influences parasite prevalence of these guenons living in Gombe; and if these guenons differ from similar guenons in other regions of Africa. The null hypothesis was unable to be rejected in all cases; hybridization could not be stated as a contributing factor for differences found in parasitic prevalence rates. Furthermore, no statistical difference was found between Gombe’s guenons, and those living in other regions of Africa in most cases. The author suspects that the abundance of parasitic generalists discovered, small sample size, and opportunistic sampling protocol contribute to these finding.
