Bacteriocenosis - poisons bacteriathat cause hemolysis.
To bacteriopheophytin are some toxins staphylococci, streptococci, kolerovochny cholerae, Escherichia coli, pathogenic of anaerobic bacteria of the genus Clostridium, in particular pathogens gas gangrene. Cm. also Toxins.

Bacteriocenosis - specific products of vital activity of microorganisms that cause lysis of red blood cells of humans and animals. Bacteriocenosis characteristic of a pathogenic species of bacteria: Streptococcus, Staphylococcus, anaerobic bacteria of the genus Clostridium, most kolerovochny cholerae, Escherichia coli, pathogenic serological types of E. coli and other Bacteriocenosis are divided into several types: the first has the properties of exotoxins (fully neutralized antitoxic serum - staphylococcal alpha-toxin), the second is the ability to hemolysis at temperatures below 37 degrees (warm-cold" hemolysins: beta-toxin Staphylococcus, Cl. perfringens); the third type are the so-called On-labile bacteriocenosis, with activity only in the reduced state, podavlajushej cholesterol and serologically related (O-streptolysin hemolytic Streptococcus, D-toxin Cl. oedematiens, tetanolysin Cl. tetani, and others). To detect hemolytic activity of the studied bacteria most often used nutrient agar with 5% defibrinirovannaya blood horses, sheep or pig. Cm. also Toxins.
