January 04, 2024Posted: January 04, 2024Read MoreCarbapenem-resistant Enterobacterales or CRE, are a group of gram-negative bacteria that are resistant to “last line” antibiotics and are very challenging to treat. These microorganisms may confer their resistance via the production of a carbapenemase, an enzyme that inactivates carbapenem antibiotics.
The five most common types of carbapenemases are KPC, OXA-48-like, VIM, IMP, and NDM.
Knowing the type of carbapenemase is crucial for therapeutic purposes, infection control, and for preventing outbreaks.

Gram staining does not only detect bacteria, it differentiates between gram-positive and gram-negative.
Although there are automated systems, manual Gram staining is still a widely used method. This is because of it's innate accuracy.
