CASE REPORT Open Access Necrotizing fasciitis involving the chest and abdominal wall caused by Raoultella planticola

Background: Raoultella planticola was originally considered to be a member of environmental Klebsiella. The clinical significance of R. planticola is still not well known. Case presentation: We describe the first case of necrotizing fasciitis involving the chest and abdominal wall caused by R. planticola. The identity of the organism was confirmed using 16S rRNA sequencing. The patient was successfully treated with the appropriate antibiotics combined with operative drainage and debridement. Conclusions: R. planticola had been described as environmental species, but should be suspected in extensive necrotizing fasciitis after minor trauma in mild to moderate immunocompromised patients. Background Raoultella planticola is a Gram-negative, aerobic, non-motile, encapsulated rod bacterium [1]. Because these organisms are closely related to Klebsiella species, they can be easily misidentified as Klebsiella pneumoniae or Klebsiella oxytoca [2,3]. R. planticola is found in water, soil, and fish and was also isolated from clinical specimen
