Klebsiella pneumoniae is a type of bacteria that can cause a range of infections. These usually develop in hospital settings.
People have K. pneumoniae in their digestive tracts. When the bacteria spread to other parts of the body, they can cause a variety of infections, including:
- urinary tract infections
- skin and wound infections
- liver abscesses
- blood infections

There are many types of K. pneumoniae bacteria. Some have capsules surrounding their cells, and others do not.
Researchers have currently identified
Humans are the
In some populations, the disease is more likely to cause certain infections. K. pneumoniae are the
Meanwhile, in Western regions, Klebsiella rarely causes meningitis. However, in Taiwan, K. pneumoniae infection is a leading cause, responsible for about
Some people develop K. pneumoniae meningitis from liver abscesses. The bacteria from the abscess can travel from the liver to the central nervous system.
In addition, catheters and tools in medical procedures can transmit K. pneumoniae into the urinary tract, the bloodstream, and wounds.
Different types of infection with K. pneumoniae can cause different symptoms, which may resemble those of other bacterial infections.
If a doctor notices that a bacterial infection persists after the initial treatment, they may order tests to identify the specific bacteria responsible. The results help them choose the most appropriate antibiotic treatment.
Anyone who suspects that they have a urinary tract infection, pneumonia, meningitis, or cellulitis — all of which can result from K. pneumoniae — should consult a doctor right away.
The table below lists common symptoms of these conditions.
shortness of breath
neck stiffness or pain
sensitivity to light
pain beneath the pubic bone
blood in the urine
Doctors treat K. pneumoniae infections with antibiotics. When an infection is hospital-associated, doctors use a class of antibiotics called carbapenems until results of sensitivity testing are available.
If a doctor suspects that the bacteria have developed antibiotic resistance, they can order tests to determine how sensitive the bacteria are to specific antibiotics, before selecting the most effective option.
It may be challenging for doctors to treat K. pneumoniae infections because increasingly fewer antibiotics are effective. Most recently, for example, some K. pneumoniae have
A doctor may prescribe a combination of antibiotics. One
When a person develops pneumonia from K. pneumoniae, doctors
People who are allergic to penicillin require a course of aztreonam or a quinolone.
Doctors usually diagnose Klebsiella infections by examining either a sample of infected tissue or a sample of:
Sometimes doctors order medical imaging tests, including:
- CT scans
Once the doctor confirms the diagnosis, they may run sensitivity tests to determine which antibiotic will most effectively treat the infection.
Anyone who suspects that they have a K. pneumoniae infection should seek medical attention right away.
If any infection persists after home care or an initial course of antibiotics, it is important to seek medical attention. The doctor may ask for additional testing to check the susceptibility of the bacteria to antibiotics.
K. pneumoniae infection is
In hospitals, K. pneumoniae can spread through person-to-person contact. People may also come into contact with the bacteria through environmental exposure, though this occurs less often.
An individual may come into contact with this type of bacteria through:
- ventilators, or breathing machines
- intravenous catheters
- urinary catheters
- open wounds
Healthy family members of people with K. pneumoniae infections have a low risk of acquiring the infection.
However, taking every hygiene precaution is essential. Hand hygiene remains the best defense against K. pneumoniae infection.
When doctors identify K. pneumoniae in samples quickly and prescribe the appropriate antibiotics right away, the prognosis improves. However, delays in diagnosis and testing are common, and this can lead to a less favorable
The prognosis for people with pneumonia from K. pneumoniae is often poor. Even when doctors choose the appropriate antibiotic therapy, mortality rates are
People with other diseases, such as diabetes, older adults, and people with compromised immune systems have the highest risks of mortality.
In people with pneumonia from these bacteria, the infection may impede lung function in the long term, possibly for months.
K. pneumoniae infections typically develop in hospital settings. People with weakened immune systems and chronic conditions have the highest risk.
K. pneumoniae have developed resistance to many antibiotics, and doctors may find it challenging to treat K. pneumoniae infections. However, testing the sensitivity of the bacteria in blood or tissue samples can help them identify the most effective course of treatment.
People with K. pneumoniae infections may transmit the bacteria to others. Taking every hygiene precaution, especially hand washing, is the best way to prevent K. pneumoniae infections from spreading.
