Gram staining, also called Gram's method, is a method of differentiating bacterial species into two large groups (Gram-positive and Gram-negative).

Hand of doctor or researcher holding a plate of microbiological cultures with colored bacteria. Concept of antibiotic resistance
Life-threatening infections are on the rise due to drug-resistant bacteria. Carbapenemase-producing organisms (CPO) are bacteria that have become resistant to a group of antibiotics known as carbapenems. CPO are emerging pathogens world wide.

Group of petri dishes with different culture media and micro organisms grown. They show biodiversity in microbiology. Isolated on white background.
Gram stain of the bacterium, Staphylococcus aureus. This bacteria is gram positive, as such it appears purple after staining due to the thick peptidoglycan. The round cells are also seen in clusters.
