![]() Different types of reagents starting from crystal violet dye to safranine are used in this procedure. In his honor, the procedure was named “Gram stain”. In 1884, Hans Christian Gram developed a different type of staining process based on the reaction of the cell walls with certain chemicals or dyes for the characterization and identification of bacteria. On the basis of oxygen dependence, bacteria are of two types:Īnd on the basis of staining, they are of the following two types: They are:įigure: Types of bacteria based on the shape Bacteria are classified into five groups according to their basic shapes. As we know that bacteria are the most primitive type of organism possessing a primitive type of nucleus and are classified into various groups on the basis of staining, shape, and oxygen dependence. Gram positive and Gram negative bacteria are the two forms of bacteria based on the Gram’staining technique, developed by Hans Christian Grams for the identification of bacteria. The major difference between gram positive and gram negative bacteria are well described below: Why are gram positive bacteria easier to kill? Which cell is stronger, gram positive or gram negative ? What antibiotics are used for gram negative bacteria? How many basal rings are present in gram negative on their flagella? ![]() Which bacteria are more susceptible to antibiotics?
