  1. ROLE OF REMOTE SENSING FOR THE SURVEILLENCE OF VIBRIOS IN THE ENVIRONMENT D. Jay Grimes The University of Southern Mississippi Gulf Coast Research Laboratory Ocean Springs, MS 39564 Vibrios in the Environment 2010 Beau Rivage Resort and Casino Biloxi, MS

  2. 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

  3. 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

  4. 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)

  5. OHHI Objective 2 Results: Relationship between total Vp (tlh) and salinity (Zimmerman et al., Appl. Environ. Microbiol., 73:7589-7596 , Figure 4.A.)

  6. This is where we’re at Vibrio Remote Sensing Report http://www.eol.ucar.edu/projects/ohhi/vibrio/

  7. Recent Maps that Include Salinity average log(Vp/g) = -2.05 + 0.097*TWATER + 0.2*SAL - 0.0055*SAL2

  8. 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”
