A Case Report of Osteomyelitis Caused by Ewingella

Mazin Barry,Almughaiseeb 

Ewingella americana is a rare gram negative, facultative anaerobic bacillus. It was first discovered in 1983, as a novel species of Enterobacteriaceae. Its origin is unknown, but it was first recognized from a clinical specimen in the Americas. It is composed of a single DNA that is similar to other Enterobacteriaceae groups by 79% [1]. It has rarely been identified as a cause of infection in people, although it has been isolated from diverse clinical samples around the world. Нe specimens were collected from diوٴerent body fluids including sputum [2], blood [3-6], wound [7], and peritoneal fluid [8]. Nonhuman sources have been identified as well: mushrooms [9], packaged meat [10], and the intestinal contents of snails [11]. A cross-sectional study was published in 2018 Dіer the research was done among five hospitals in South Africa in order to identify hospital pathogens. In addition, E. americana was found in one of these samples [12]. We present a case of osteomyelitis of the hand precipitated by Raynaud’s phenomenon.
