growth of Klebsiella pneumoniae on a growth medium of MacConkey agar.

Klebsiella pneumoniae is a type of Gram-negative bacteria that can cause different types of healthcare-associated
infections, including pneumonia, bloodstream infections, wound or surgical site infections, and meningitis. Increasingly,
Klebsiella bacteria have developed antimicrobial resistance, most recently to the class of antibiotics known as carbapenems.
Klebsiella bacteria are normally found in the human intestines (where they do not cause disease). They are also found in human
stool (feces). In healthcare settings, Klebsiella infections commonly occur among sick patients who are receiving treatment for other
conditions. Patients whose care requires devices like ventilators (breathing machines) or intravenous (vein) catheters, and patients who
are taking long courses of certain antibiotics are most at risk for Klebsiella infections. Healthy people usually do not get
Klebsiella infections.
