Klebsiella pneumoniae
Klebsiella infections and resistant strains
The short answer
Klebsiella bacteria can inhabit the gut. Klebsiella pneumoniae can cause lung, blood and wound infections, particularly in healthcare settings.
Transmission and timing
Hands, contaminated equipment and direct contact matter in healthcare settings. Airborne spread is not the usual route; contact precautions are part of care.
CDC ↗Symptoms and risk groups
Symptoms vary by infected organ. The bacterium’s name on a laboratory report alone does not establish the site or severity of disease; clinical findings matter.
CDC ↗When to seek help
Seek emergency help for suspected infection with altered consciousness, severe breathing difficulty or rapid deterioration. Do not wait for a culture result.
NHS ↗For life-threatening symptoms, severe breathing difficulty or altered consciousness, call your local emergency number (112 in Türkiye).
What does the test show?
Culture and antimicrobial susceptibility help assess suspected infection. Interpret specimen type alongside symptoms; colonization alone is not disease.
CDC ↗Care and treatment approach
Antibiotic choice depends on susceptibility and clinical condition. Carbapenem resistance limits options but does not automatically mean no treatment is available.
CDC ↗Prevention and everyday life
Hand hygiene and adherence to healthcare contact precautions matter. Communicate known resistance or carriage when transferring between care facilities.
CDC ↗Special situations and risk groups
Intensive care, invasive devices and prolonged antibiotic exposure can affect resistant-infection risk. The team should regularly review device and antibiotic needs.
CDC ↗A common misunderstanding
CRE means carbapenem-resistant Enterobacterales, not Klebsiella alone. People carrying a resistant organism are not necessarily ill, and colonization usually does not require treatment.
CDC ↗Clinical assessment note
Document colonization, infection and infection-control needs separately. Include resistance information in transfer records and coordinate with the local infection-control team.
CDC ↗Bring a question to your appointment
Does this result require treatment, contact precautions or both, and what information should I share at another facility?
International evidence, local decisions
Each source’s country is identified. Vaccine access, reimbursement, isolation and reporting rules vary. Use current guidance and your clinician’s advice in your country; English does not imply UK or US eligibility.
