What is the Difference Between Klebsiella and Pseudomonas?

Klebsiella and Pseudomonas are both gram-negative bacteria belonging to the class Gammaproteobacteria, but they differ in several aspects:

• Family: Klebsiella belongs to the family Enterobacteriaceae, while Pseudomonas belongs to the family Pseudomonadaceae.
• Motility: Members of the genus Klebsiella are non-motile, whereas members of Pseudomonas are motile.
• Shape: Klebsiella pneumoniae is a rod-shaped, non-motile, facultative anaerobic bacterium with a prominent polysaccharide capsule. Pseudomonas aeruginosa, on the other hand, is a gram-negative, rod-shaped bacterium that is motile.

Both Klebsiella and Pseudomonas are opportunistic pathogens that can cause various infections, especially in immunocompromised patients, such as those with burns or ventilator-associated pneumonia. They are also known to form biofilms, which contribute to their survival and persistence in various environments, including chronic wounds.

Comparative Table: Klebsiella vs Pseudomonas

Here is a table comparing the differences between Klebsiella and Pseudomonas:

Klebsiella and Pseudomonas are both Gram-negative bacteria belonging to the Gammaproteobacteria class, but they differ in their family and motility. Klebsiella belongs to the family Enterobacteriaceae and is non-motile, while Pseudomonas belongs to the family Pseudomonadaceae and is motile. In terms of antibiotic resistance, Klebsiella is more resistant to Tetracycline, Gentamycin, Ciprofloxacin, and Sulfamethoxazole, while Pseudomonas is more resistant to other antibiotics.
