Characteristics of Gram-Positive Bacteria
Gram-positive Bacteria FAQ
What is a Gram positive bacteria?
Gram-positive bacteria may be cocci or bacilli. (See figure How Bacteria Shape Up .) Some Gram-positive bacteria cause disease. Others normally occupy a particular site in the body, such as the skin. These bacteria, called resident flora , do not usually cause disease. Gram-positive bacilli cause certain infections, including the following:
What are Gram-positive bacteria?
Gram-positive bacteria are a type of bacteria that have a thick cell wall. This cell wall helps protect the bacteria from antibiotics and other substances that might damage them. Gram-positive bacteria can cause a range of infections, from food poisoning to serious respiratory diseases.
Are Gram positive organisms pathogenic?
In the classical sense, six gram-positive genera are typically pathogenic in humans. Two of these, Streptococcus and Staphylococcus, are cocci (sphere-shaped). The remaining organisms are bacilli (rod-shaped) and can be subdivided based on their ability to form spores.
How are Gram positive and Gram negative bacteria classified?
Gram-positive bacteria are classified by the color they turn after a chemical called Gram stain is applied to them. Gram-positive bacteria stain blue when this stain is applied to them. (Other bacteria stain red. They are called gram-negative.) Gram-positive and gram-negative bacteria stain differently because their cell walls are different.
