Klebsiella is a type of bacteria commonly found in nature. In humans, the bacteria are often present in parts of the digestive tract where they do not generally cause problems. In the United States, Klebsiella pneumoniae and Klebsiella oxytoca are the two strains responsible for most human illnesses. Many Klebsiella infections are acquired in the hospital setting or in long-term care facilities. In fact, Klebsiellae account for up to 8% of all hospital-acquired infections. People with a compromised immune system and/or people who have an implanted medical device (such as a urinary catheter or airway tube) are more at risk for Klebsiella infections. Extensive use of antibiotics has resulted in the development of antibiotic-resistant strains of Klebsiella. These infections can be more aggressive and difficult to treat.
