Diphtheria is caused by bacteria that adhere to the lining of your respiratory system and generate a toxin that damages your respiratory tissue cells. The pathogenesis of diphtheria is based upon two primary determinants: the ability of a given strain of C diphtheria to colonize in the nasopharyngeal cavity and/or on the skin, and its ability to produce diphtheria toxin. The organism produces a toxin that inhibits cellular protein synthesis and is responsible for local tissue destruction and formation of the pseudomembrane that is characteristic of this disease.
See lessDiphtheria is a serious infection caused by strains of bacteria called Corynebacterium diphtheriae that make a toxin (poison). It is the toxin that can cause people to get very sick.

See lessCorynebacterium diphtheriae is the pathogenic bacterium that causes diphtheria. It is also known as the Klebs–Löffler bacillus, because it was discovered in 1884 by German bacteriologists Edwin Klebs (1834–1912) and Friedrich Löffler (1852–1915).

See lessCorynebacterium is a genus of bacteria that are Gram-positive and most are aerobic. They are bacilli (rod-shaped), and in some phases of life they are, more specifically, club-shaped, which inspired the genus name (coryneform means "club-shaped").

In bacteriology, gram-positive bacteria are bacteria that give a positive result in the Gram stain test.
Gram-positive bacteria take up the crystal violet stain used in the test, and then appear to be purple-coloured when seen through an optical microscope. This is because the thick peptidoglycan layer in the bacterial cell wall retains the stain after it is washed away from the rest of the sample, in the decolorization stage of the test.
Atypical mycobacteria are mycobacteria that do not cause tuberculosis or leprosy. They are found in nature, such as in soil, water, and animals, and may colonize poorly sanitized medical equipment.

Atypical mycobacteria are mycobacteria that do not cause tuberculosis or leprosy. They are found in nature, such as in soil, water, and animals, and may colonize poorly sanitized medical equipment. They can cause various infections in humans, such as skin, soft tissue, lymph node, lung, and disseminated infections. Some of the most common species of atypical mycobacteria that cause human infections are:
1. Mycobacterium avium complex (MAC)
2. Mycobacterium kansasii
3. Mycobacterium marinum
4. Mycobacterium ulcerans
5. Mycobacterium abscessus complex
6. Mycobacterium chelonae, and
7. Mycobacterium fortuitum
Mycobacterium tuberculosis has many virulence factors, which can be divided across: 1. Lipid and fatty acid metabolism, 2. Cell envelope proteins, 3. Macrophage inhibitors, 4. Kinase proteins, 5. Proteases, 6. Metal-transporter proteins, and 7. Gene expression regulators. Some of the virulence factoRead more
