The significance of the transmission of animal viruses in sewage polluted fresh and marine waters becomes an increasingly important factor as more and more evidence is presented to support the fact that in the case of many viral types one virus particle constitutes an infective dose. Therefore it is very important that a method of determining the extent of viral pollution in sewage polluted bodies of marine and fresh water be found.

Show moreThe significance of the transmission of animal viruses in sewage polluted fresh and marine waters becomes an increasingly important factor as more and more evidence is presented to support the fact that in the case of many viral types one virus particle constitutes an infective dose. Therefore it is very important that a method of determining the extent of viral pollution in sewage polluted bodies of marine and fresh water be found. The longevity of f2 bacteriophage in both marine and fresh water sewage polluted samples was determined, and shown to be 3 to 4 days for marine water and 8 days for fresh water. It was also shown that the culture medium in which the f2 phage was produced, and the larger macromolecular polymers commonly found associated with sewage had a favorable affect in increasing the longevity of f2 phage. It was shown that f2 bacteriophage could be used to follow the initial dispersion of the sewage boil arising from an ocean outfall sewerage system. From these results it was concluded that f2 bacteriophage could be used for more detailed studies concerned with the transmission of viruses in sewage polluted waters.

This study was undertaken to determine the distribution and possible source of Staphylococcus aureus, s. epidermidis, other Micrococcaceae , and enterococci recovered from samples of water collected at the following locations: the Pompano Beach sewage outfall, the Intracoastal Waterway, 5 miles due east of the Boca Raton Inlet, over the 65 ft Boca Raton reef, and in 5 ft of water along the Boca Raton beach.

Show moreThis study was undertaken to determine the distribution and possible source of Staphylococcus aureus, s. epidermidis, other Micrococcaceae , and enterococci recovered from samples of water collected at the following locations: the Pompano Beach sewage outfall, the Intracoastal Waterway, 5 miles due east of the Boca Raton Inlet, over the 65 ft Boca Raton reef, and in 5 ft of water along the Boca Raton beach. It was also of interest to study the feasibility of employing s. aureus as an indicator of fecal pollution in the marine environment. Neither staphylococci nor enterococci were recovered from 5 samples of beach sand collected from the high tide line to the low tide line. Only low concentrations of staphylococci were recovered from samples collected from the Intracoastal Waterway. The staphylococci recovered from the marine locations do not appear to be true marine bacteria. They do not appear to be originating from bathers, beach washings or the Intracoastal Waterway. Sampling was inadequate to reach definite conclusions on the origin of the Micrococcaceae recovered in the ocean. However, these data indicate the staphylococci originate from the Pompano Beach sewage outfall. Staphylococcus aureus appears to be more resistant to the conditions of the marine environment than the other Micrococcaceae, enterococci or other sewage bacteria recovered on Mannitol Salt Agar and m-Enterococcus Agar. The mean per cent recovery of S. aureus increases with increased distances downstream from the outfall to the 65 ft reef and sampling site 5 miles offshore. ~· aureus appears to be a good indicator of fecal pollution in the marine environment. Survival studies of washed cells of a coagulase positive Staphylococcus aureus run in autoclaved sea water and autoclaved Intracoastal water gave mean decimal reduction times of 16.6 hr and 11.4 hr, respectively. Staphylococci were not recovered from Bryothamnion triguetrum,Caulerpa sertularioides f. brevipes, Dasycladus vermicularis or Padina sanctae-crucis. Ten Micrococcaceae recovered from the ocean were not inhibited by extracts prepared from these algae. Intact segments of these algae possessed antibacterial activity against most, if not all of these Micrococcaceae.

Two methods, a membrane filter-fluorescent antibody technique for detection of Staphylococcus aureus, and isotopic determination of relative heterotrophic activity, were compared with a standard technique based on the recovery of coliform organisms for evaluation as indices of marine pollution. Water samples were collected from coastal areas of Pompano Beach and Boca Raton, Florida. Coliform and staphylococci survival in seawater was studied under laboratory conditions.

Show moreTwo methods, a membrane filter-fluorescent antibody technique for detection of Staphylococcus aureus, and isotopic determination of relative heterotrophic activity, were compared with a standard technique based on the recovery of coliform organisms for evaluation as indices of marine pollution. Water samples were collected from coastal areas of Pompano Beach and Boca Raton, Florida. Coliform and staphylococci survival in seawater was studied under laboratory conditions. The effect of exposure to seawater on substrate uptake by coliforms and other sewage microorganisms was studied using isotopic methods. The results of these studies support the feasibility of using S· aureus as a long-range indicator of marine pollution. Under natural conditions, S· aureus appears more resistant to seawater than coliform organisms, although the reverse was found under laboratory conditions. Seawater inhibited uptake of glucose and lactose by Escherichia coli and other sewage organisms. Relative heterotrophic potentials in terms of glucose and lactose uptake velocities were not significantly affected in coastal waters by the influx of bacteria and nutrients in sewage outfall effluent.

A brown tide bloom of the pelagophyte Aureoumbra lagunensis caused significant impacts to north Indian River Lagoon (IRL) in 2012-2013, including seagrass die-offs, fish kills, and reduced growth and grazing of ecologically important bivalves. There is potential for another pelagophyte, Aureococcus anophagefferens, to expand into this system. Filtration rates (FR) of the pleated tunicate Styela plicata exposed to Aureoumbra lagunensis and Aureococcus anophagefferens were measured against...
Show moreA brown tide bloom of the pelagophyte Aureoumbra lagunensis caused significant impacts to north Indian River Lagoon (IRL) in 2012-2013, including seagrass die-offs, fish kills, and reduced growth and grazing of ecologically important bivalves. There is potential for another pelagophyte, Aureococcus anophagefferens, to expand into this system. Filtration rates (FR) of the pleated tunicate Styela plicata exposed to Aureoumbra lagunensis and Aureococcus anophagefferens were measured against exposure to a control alga (Tisochrysis lutea) in order to determine its potential use as a bioremediator against these harmful algal blooms (HABs). In addition, whether S. plicata might serve as a vector of HABs was studied by culturing fecal deposits. Short-term exposure to HABs significantly reduced FR, whereas long-term exposure indicates comparable cell removal compared to the control. Vector potential of S. plicata was inconclusive. Results warrant further research to determine whether S. plicata can acclimate or respond to HAB conditions over time.

Recently, there has been an increase in marine mammal mortalities, most commonly Atlantic bottlenose dolphins, Tursiops truncatus, which is an alarming indication of the health status of the marine ecosystem. Studies have demonstrated that some free-ranging dolphins exhibit a suppressed immune system possibly because of exposure to contaminants or infectious microorganisms.

Show moreRecently, there has been an increase in marine mammal mortalities, most commonly Atlantic bottlenose dolphins, Tursiops truncatus, which is an alarming indication of the health status of the marine ecosystem. Studies have demonstrated that some free-ranging dolphins exhibit a suppressed immune system possibly because of exposure to contaminants or infectious microorganisms. However, this research has been limited due to a lack of commercially available marine-specific antibodies. Therefore, the first chapter of this thesis aims to identify cross-reactive terrestrial-specific antibodies that could be used to phenotype and compare the immune cell populations of dolphins under human care and free-ranging dolphins. The second chapter aims to utilize terrestrial-specific growth factors and dendritic cell (DC) surface markers to generate, characterize, and compare ex vivo DCs from peripheral blood mononuclear cells (PBMCs) of dolphins under human care and free-ranging dolphins. In summary, I have identified differences within the PBMCs and ex vivo generated DCs of dolphins under human care and free-ranging dolphins that could potentially shed light on the impact of environmental contaminants and infectious microorganisms on immune cells which could lead to increased morbidity and mortality.
