Corynebacterium

Corynebacteriaceae is a family of gram-positive, non-spore-forming, rod-shaped, aerobic, uncultivable bacteria (aerobic in the absence of oxygen or anaerobic) that are typical representatives of the normal microflora of the oral cavity and upper respiratory tract of humans, as well as representatives of the rodent family. S. aureus, Helicobacter pylori and P. aeruginosa are the main pathogenic microorganisms of the family, especially dangerous to humans: staphylococcus is the causative agent of purulent infectious diseases of various localizations, including staphyloderma in children, food toxic infections, airborne infections of newborns caused by Streptococcus agalactiae, pneumonia, cystitis, arthritis and meningitis.

Corienrbaccarium - see Corynebacteria. They are a group of bacilli, spherical bacteria that can be unicellular or multicellular. They live inside the human body, usually affecting the skin or respiratory tract. Corynbacterium causes skin diseases such as impetigo, boils and others. There are about 80 species of corynbacteria in nature. Most of them are pathogenic for humans and animals and cause various diseases in animals and humans. For example, pathogenic: C. minutissimum, C. facultative anaerobicum, C. pseudoaminovalerate C, C. asteroides and many others. Toxigenic corynebacteria produce enterotoxins of types A, B, C, D, which cause toxic-septic diseases in newborns. Corynebacterium produces a number of other (irritating) exotoxins that play a role in the development of various inflammatory tissue reactions (particularly at the site of pus formation). Many types of corynebacteria can grow only in the presence of foreign microbial cells. At the same time, they produce substances that lyse cells that are foreign to the host. Also, all pathogenic corynebacteria produce heat-labile exotoxins (lethal toxins), which are known to be involved in their virulence and cause the death of animals, or exotoxin C, resistant to high heating temperatures, is formed in the culm
