The Fish Disease Laboratory at CSUH is primarily involved with research on bacterial and protozoan pathogens of fish, shrimp, and corals. My research over the past years has centered on isolation and idenficiation of bacterial pathogens with particular interest in antibiotic resistance. Undergraduate and graduate students working in the lab have identified antibiotic resistant bacterial strains of Aeromonas, Citrobacter, Edwardsiella, and Mycobacterium from cultured ornamental fish, as well as restistant strains of Vibrio from tropical marine fish, penaeid shrimp, and corals. To address the problem of drug resistance research projects, in collaboration with the private sector of the aquaculture industry, have focused on the development of new techniques for more efficient delivery of antiobiotics and immunostimulants to fish and shrimp. Environmental studies have focused on monitoring the re-emergence of antibiotic resistant bacteria in freshwater and marine sediments. The laboratory is equipped with a Bactron II Anaerobe Chamber for conducting research on anaerobic bacterial diseases of fish, and the identification of the normal anaerobic intestinal flora of fish.
