Research in mice offers clues for vaccinating against deadly bacteria

In the U.S., the bacterium Klebsiella pneumoniae is a common cause of urinary tract infection, bloodstream infection and pneumonia. While infections with the bacterium can be easily treated in some, Klebsiella has a dangerous flip side: It also is frequently resistant to antibiotics, making it extraordinarily difficult to treat in others. About half of people infected with a hypervirulent, drug-resistant strain of the bacterium die.
