Gram negative bacteria infection symptoms?

First, Gram staining reaction is an important characteristic of bacterial classification and identification. It was founded in 1884 by gram, a Danish physician. Gram stain can not only observe the morphology of bacteria, but also divide all bacteria into two categories: those with blue purple staining reaction are called Gram-positive bacteria, which are expressed by G +; Gram negative bacteria with red staining reaction (polychromatic color) are called gram negative bacteria, which are represented by G -.

Second, the different reactions of bacteria to Gram staining are caused by the different composition and structure of their cell walls. The cell wall of Gram-positive bacteria is thick (20-80nm), mainly composed of peptidoglycan and teichoic acid, with only one layer structure. The main component is peptidoglycan, accounting for 50% - 90% of the dry weight of cell wall. In the dyeing process, when treated with ethanol, the pore size of the reticular structure becomes smaller and the permeability decreases due to dehydration, which makes the crystal violet iodine complex remain in the cells and is not easy to decolorize; The content of peptidoglycan in the cell wall of gram negative bacteria is low, but the content of lipid is high. When treated with ethanol, the lipid dissolves and the permeability of cell wall increases, which makes the crystal violet iodine complex easy to be extracted by ethanol and decolorized, and then dyed with the color of complex dye (carmine), so it appears red.

Third: mainly a variety of antibiotics. However, due to the increasingly serious drug resistance, many antibiotics have lost their glory in the past, such as penicillin. Many doctors are also using antibiotics indiscriminately. They should seek responsible doctors for treatment. Experienced doctors use narrow-spectrum antibiotics, which is less resistant than broad-spectrum antibiotics.

matters needing attention
