Burkholderia cocovenenansproduces a lethal toxin (Bongkrekic acid) that leads to high fatality in food poisoning cases. However, B. cocovenenanswas combined in Burkholderia gladioliin 1999. B. gladioliwas originally described as a phytopathogenic bacteria that sometimes causes pneumonia in humans and that acts as an opportunistic pathogen. We thought that it was clinically dangerous to describe these two species without considering their pathogenicities. From our data of 16S rRNA sequence analysis, DNA‐DNA hybridization, and fatty acid analysis, we could confirm that B. cocovenenansand B. gladiolishould be categorized as a single species. However the species really weaved lethal toxin‐producing strains with non‐lethal strains. To emphasize that B. gladiolicontains two different pathogens, we describe a new pathovar, B. gladiolipathovar cocovenenans, for the lethal toxin‐producing strains. We provide characteristics that differentiate this lethal toxin‐producing pathovar from other phytopathogenic pathovars within B. gladioli, together with an emended description of B. gladioli. |
