Leuconostoc mesenteroidesbacteremia in a patient with exposure to unpasteurised raw milk

Abstract

Leuconostocspp are lactic acid-producing bacteria closely related to theStreptococcusfamily. While usually associated with the fermentation of dairy products and sauerkraut, they are rarely associated with human infections. This is a case report of an immunocompetent patient found to haveL. mesenteroidesbacteremia associated with raw milk and poor dentition as the likely source of infection, which was treated successfully with daptomycin as this genus is intrinsically resistant to vancomycin.
