Weissella confusa Bacteremia in an Immune-Competent Patient with Underlying Intramural Hematomas of the Aorta

Weissella confusa is a catalase-negative and gram-positive coccobacillus that is intrinsically resistant to vancomycin [1]. This species can cause infections, such as bacteremia, endocarditis, and abscess in immunocompromised patients [2-7]. Until now, reports on infections caused by W. confusa have been limited as this species has been frequently misidentified as Lactobacillus or Leuconostoc when identified using commercial kits [8]. Herein, we report the second case of W. confusa bacteremia in an immunocompetent patient from Korea, who had intramural hematomas of the aorta.
