Difference Between Gram Positive and Gram Negative Bacteria

Difference Between Gram Positive and Gram Negative Bacteria


Difference Between Gram Positive and Gram Negative Bacteria A microorganism could be a massive cluster of minute, animate thing, and microscopic organisms. These are additional classified as being cells as a result of they’re lacking verity nucleus. These varieties of microscopic organisms comprise of an easy organic structure. Their structure includes the plasma membrane, capsule, DNA, pili, flagellum, cytoplasm, and ribosomes. microorganism is classified as gram-positive or gram-negative. This classification depends upon the staining ways. The Danish life scientist J.M.C. Gram has devised a way of staining microorganism. He used a dye known as crystal or antimycotic agent. His methodology helps to tell apart between differing types of microorganism. The gram-staining characteristics of microorganism ar known as positive or negative. And it depends upon whether or not the microorganism take up and retain the helminthic stain or not. allow us to have a close verify these 2. Also, distinction between gram positive and gram negative microorganism are well bestowed here.

Difference Between Gram Positive and Gram Negative Bacteria

Gram positive bacteria:

Gram-positive bacterium retain the colour of the fungicide stain within the staining. Such bacterium embody staphylococci, streptococci, pneumococci. Also, some others area unit the microorganism that causes contagious disease and anthrax. gram-positive bacterium show the visible violet color upon the applying of mordant means that iodine and fermentation alcohol. gram-positive bacterium represent a semi-permeable membrane consisting of multiple layers of peptidoglycan. It forms a rigid and thick structure. Its cell walls to boot having teichoic acids and phosphate. The teichoic acids area unit of 2 varieties, one is lipoteichoic acid and therefore the different is that the teichoic wall acid.

Gram negative bacteria:

Gram-negative microorganism don’t retain the vermifuge stain and additional, it takes the colour of the red stain in Gram’s technique of staining. this can be the main characteristic of microorganism that have a semi-permeable membrane composed of a skinny layer of peptidoglycan. principally these microorganism embody most of the microorganism unremarkably found within the GI tract. Some ar gonococci inflicting Cupid’s disease and meningococci inflicting microorganism infectious disease.

Key points of gram positive and gram negative:

          The cytomembrane of gram-positive bacterium is consisting of thick layers of peptidoglycan. Whereas the cytomembrane of gram-negative bacterium is consisting of skinny layers of peptidoglycan.

During the gram staining procedure, a gram-positive cell retains the purple-colored stain. however don’t retain the purple coloured stain.

Gram-positive bacterium manufacture exotoxins, whereas gram-negative bacterium manufacture endotoxins.

Gram-negative bacterium cause several infections in humans. Some common health problem is stomach upset, unwellness, pneumonia, meningitis, etc. another infections additionally happen within the blood cells, blood, wound infections, etc. thanks to these bacterium.
