Marine Microbiology

Research in my Marine Microbiology laboratory is primarily focused on the Vibrios.
The genus Vibrio now includes over 100 species and is considered by most marine microbiologists to comprise the dominant culturable bacteria in the ocean. Much of my research has focused on V. parahaemolyticus and V. vulnificus, although we have recently looked at the abundance and distribution of V. cholerae in the Northern Gulf of Mexico. We are especially interested in the ecology of these indigenous marine bacteria and the factors that allow them to survive in the environment, to cause disease in humans and other animals. Current research projects include: forecasting the abundance and distribution of V. parahaemolyticus and V. vulnificus in coastal waters by using satellite remote sensing; examining the abundance and distribution of virulent strains of V. parahaemolyticus in the Northern Gulf of Mexico; viable but nonculturable Vibrios; V. vulnificus and nerotizing fasciitis; naturally occurring Vibrios and other bacteria in elasmobranch fishes; examining the distribution and function of the enzyme urease in V. parahaemolyticus strains and understanding the role of Vibrios in biodegradation of wastes, including petroleum, in the ocean. Finally, because the GCRL has a large research and development program in marine fish aquaculture, the Marine Microbiology laboratory works with the GCRL marine aquaculture team to study and find cures for bacterial diseases, especially vibriosis.

Dr. Grimes will teach COA in Fall 2016.
