Ewingella americana

Ewingella americana is a Gram-negative rod, and the only species in the genus Ewingella. It was first identified and characterized in 1983. Ewingella is in the family Yersiniaceae. The organism is rarely reported as a human pathogen, though it has been isolated from a variety of clinical specimens, including wounds, sputum, urine, stool, blood, synovial fluid, conjunctiva, and peritoneal dialysate. The bacterium is named in honor of William H. Ewing, an American biologist who contributed to modern taxonomy.
