In 1965, a group of CDC researchers described a species of gram-negative, facultatively anaerobic bacteria in the family Enterobacteriaceae, which they named Edwardsiella (for CDC microbiologist Philip R.

These organisms infect a variety of fish, reptiles, and amphibians and are opportunistic pathogens for humans.
