What are the Health Risks from Marine Vibrios? • Vibrio cholerae • Cholera • Wound infections • Gastroenteritis • Vibrio vulnificus • Primary septicemiaa • Wound infectionsb • Gastroenteritis?? • Vibrio parahaemolyticus • Gastroenteritis • Wound infections • And there are other Vibrio agents of risk a b
Satellite-based Remote Sensing • Satellites can now detect many physical and chemical signals from the ocean • Emitted signals, e.g., sea surface temperature (SST), are the most dependable • Shallow coastal areas, cloud cover, haze, and storms present problems to accurate RS • Many RS signals correlate well with real-time or in situ measurements • A major current problem is that many satellites have reached the end of their useful life
OHHI Objective 2 Results: Predicted Vp vs. observed Vp correlated Mean log10V. parahaemolyticus/g = -0.84 + 0.11 x SST r = 0.692 for IS and r = 0.673 for RS (Phillips et al., 2007, J. Food Prot. 70:879-884, Figure 1)
OHHI Objective 2 Results: Relationship between total Vp (tlh) and salinity (Zimmerman et al., Appl. Environ. Microbiol., 73:7589-7596 , Figure 4.A.)
This is where we’re at Vibrio Remote Sensing Report http://www.eol.ucar.edu/projects/ohhi/vibrio/
Recent Maps that Include Salinity average log(Vp/g) = -2.05 + 0.097*TWATER + 0.2*SAL - 0.0055*SAL2
Next: Nowcasting to Forecasting • V. parahaemolyticus in molluscan shellfish • V. vulnificus in molluscan shellfish • Vibrios in coastal water at bathing beaches 10,000 Vp/g at 30o15’52”N, 89o06’48”W SST from MODIS Precise data from a “Tricorder”
