They are the following:Picture 2: A gram stain procedure showed gram positive bacteria on the left and gram negative bacteria on the right. Learn what it involves and when your doctor might order it. Gram stain or Gram staining, also called Gram's method, is a method of staining used to distinguish and classify bacterial species into two large groups: gram-positive bacteria and gram-negative bacteria. (gram stain procedure gran negative positive bacteria)Photo 3: Gram positive bacteria remain purple in color while gram negative bacteria turn pink.

Gram staining is a microbiologic procedure used to differentiate Gram-negative from Gram-positive bacteria. Bacteria that stain purple are considered Gram-positive, and those that stain pink, Gram-negative. If your doctor suspects you have an infection, they may order a culture and gram stain to check for bacteria. These types of infections are typically treated differently. They may also order other tests to help diagnose your illness.In order to perform a gram stain, your doctor will need to collect a sample of body fluid or tissue for analysis. If your doctor orders a gram stain on a sample of blood or tissue, some risks are involved in collecting the sample.

It gives relatively quick results as to whether bacteria or fungi are present and, if so, the general type (s).
It was developed by Hans Christian Gram; a Danish physician, in 1884.
This can help your doctor determine an effective treatment plan. Your treatment plan and outlook will vary depending on your diagnosis. Gram staining is a microbiologic procedure used to differentiate Gram-negative from Gram-positive bacteria.It was developed by Hans Christian Gram; a Danish physician, in 1884. If they’re positive, it means bacteria were present. If bacteria are present, this test can also help your doctor learn if the bacteria are gram negative or gram positive. If your gram stain is negative for disease-causing bacteria, your doctor may order other tests to learn what’s causing your symptoms.
For example, to collect a sample of sputum, they may ask you to cough some into a specimen container. The cells are colored red or violet so as to distinguish its group.

The main benefit of a gram stain is that it helps your doctor learn if you have a bacterial infection, and it determines what type of bacteria are causing it. After they have collected the sample, they will send it to a laboratory for testing. Its primary purpose is to differentiate gram-positive from gram-negative bacteria.Identifying and classifying bacteria are important as they help in the presumptive diagnosis of various types of diseases.It also helps in understanding the chemical makeup of the cell wall of bacteria which is helpful in determining the course of treatment for a specific type of disease. The cells are colored red or violet so as to distinguish its group. A microorganism is gram-positive if the stain remains violet secondary to the presence of peptidoglycan in the cell wall. (how does gram positive and gram negative looks like)Picture 4 : Gram staining and the steps needed to complete the procedure.The composition of the cellular wall of gram-positive and gram-negative bacteria tells the gram staining differences. Gram stain testing is a method for classifying bacteria based on their cell wall. Different types of bacterial infections may also require different treatments. Your doctor can use a gram stain to learn if bacteria are responsible for your symptoms and what types of bacteria are present. The following principles apply:The gram-staining procedure is one of the most important procedures in microbiology. To collect a sample of blood, they may perform a blood draw. If you’re diagnosed with a bacterial infection, your doctor may prescribe antibiotics. Because of the staining technique used, gram-positive bacteria will appear purple under a microscope and gram-negative bacteria will appear pink. The shape, size, and quantity of bacteria present will also provide information about your infection.There are no known risks involved in performing a gram stain on a sample of urine, stool, or mucus. A microorganism is gram-positive if the stain remains violet secondary to the presence of peptidoglycan in the cell wall.On the other hand, a microorganism is gram-negative if the stain is red secondary to the thin peptidoglycan wall.There are three processes involved in gram staining.
