Hypervirulent Klebsiella pneumoniae capsular genotypes K1 and K2 are common pathogens responsible for community-acquired liver abscesses and invasive infections especially in East Asia. We report a Japanese man with diabetes mellitus who rapidly developed emphysematous cholecystitis and fulminant disseminated infection with life-threatening multiple organ-system failure due to K. pneumoniae K2 strains belonging to sequence type 65. In East Asia, clinicians should be aware of fulminant infections caused by hypervirulent K2 strains in patients with community-acquired K. pneumoniae infections. Further epidemiological studies are warranted to elucidate the clinical features associated with the virulence K. pneumoniae K2 strains.
