Klebsiella and Proteus are bacteria that can cause urinary tract infections, and in some cases, bloodstream infections and pneumonia.
It is an organism with a capsule, which is a special structure morphology.

Klebsiella is a genus of bacteria commonly found in the environment and the gastrointestinal tract of humans and animals. Some species of Klebsiella can cause infections in humans, particularly in healthcare settings. Klebsiella pneumoniae is a notable pathogenic species that can cause pneumonia, urinary tract infections, and bloodstream infections.
Klebsiella pneumoniae can cause infections such as pneumonia, urinary tract infections, bloodstream infections, and wound infections. It can be particularly dangerous in healthcare settings due to its ability to develop antibiotic resistance.
Klebsiella pneumonia is a type of bacterial pneumonia caused by infection with the Klebsiella pneumoniae bacterium, a gram-negative bacteria which is typically carried in fecal material and ingested through accidental aspiration or exposure to contaminated medical instruments. This bacterial infection is usually opportunistic, meaning that it appears in patients who are already battling an existing medical problem or infection, and it can be very dangerous for some patients.
Klebsiella pneumoniae is a rod-shaped bacterium that typically forms pairs or chains of cells. This arrangement is referred to as a diplococci or streptococci arrangement. The cells are encapsulated, giving them a robust structure.
Biochemical tests such as indole test and citrate utilization can help differentiate between Klebsiella pneumoniae and Citrobacter freundii. Klebsiella pneumoniae is indole negative and citrate positive, while Citrobacter freundii is indole positive and citrate negative. Additional tests like urease and motility can also aid in differentiation.
Pneumonia can be caused by different types of bacteria, so the Gram stain result can vary. Common bacteria causing pneumonia like Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are Gram-positive, while others like Klebsiella pneumoniae and Pseudomonas aeruginosa are Gram-negative. Gram staining is just one method used in identifying bacteria causing pneumonia, and further tests are often required for accurate diagnosis and treatment.
On MacConkey's agar, Klebsiella pneumoniae appears as pink or mauve mucoid colonies with a metallic sheen. On nutrient agar, it appears as smooth, round, and convex colonies with a pale white or cream color.
