What Are Gram Negative Antibiotics?

Gram-negative bacteria generally refer to bacteria with a red Gram stain. In the Gram staining experiment, crystal violet was first added, and then another counterstaining dye (usually safranin or fuchsine was used), so that all the Grams were added. Negative bacteria are stained red or pink. With this test we can distinguish between two bacteria with different cell wall structures. Gram-positive bacteria will show the color of gentian violet in the decolorization solution after the reaction.

Gram-negative bacteria, represented by E. coli. E. coli is a facultative species and generally lives in the intestine and in anaerobic environments. Gram-negative cell walls are characterized by a layer of outer memberane that is different from the positive species. As of 2011, there have been many studies on E. coli. In addition to whether it is an indicator of contamination in general foods, many molecular biology studies need to use E. coli as an experimental host.

In addition to E. coli, Proteus, Shigella, Pneumoniae, Brucella, Influenza (Hemophilus), Parainfluenza (Hemophilus), Kata (Morella), Acinetobacter, Yersinia Genus, Legionella pneumophila, Pertussis, Parapertussis, Shigella, Pasteurella, Vibrio cholerae, Parahaemolyticus, Pseudomonas Shigella, etc. are also Gram-negative bacteria.
