Marine Microbiology

Research in the 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 the research has focused on V. parahaemolyticus and V. vulnificus, although we have recently started looking 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 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; 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 bacterial diseases, especially vibriosis.

Dr. Grimes will teach "Oceans and Human Health” in the fall 2014 semester, Monday and Wednesday, 10:30 – 11:45 a.m.
