Ewingella americana: an emerging bacterial pathogen from diarrhea at China and Guinea friendship hospital of Kipé/Conakry

Abstract

Ewingella americana (E. americana) is the only species of the genus of Ewingella in the familly Enterobacteriaceae. It is becoming reported in various human infections. The aim of this paper was to describe E. americana strain isolated from human diarrhea at China and Guinea friendship hospital of Kipé/Conakry. A sample of diarrheal stools from 18-Years old patient was studied. After 24 hours coprocultures at 37°C, the bacterial identification and antibiogram were processed on Vitek 2 Compact 15 (Biomérieux, Marcy l'Etoile, France). The bacterial isolate was identified as E. americana. This isolate was susceptible to majority (12/18) of antibiotics tested, but it was resistant to cefoxitin, amikacin and nalidixic acid, and showed intermediate sensitivity to cefalothin, gentamicin and tobramycin. We report here, to our knowledge the first case of E. americana isolated from human diarrhea, with multi-drug resistance.
