Fecal Streptococcus

Streptococci, members of the genus Streptococcus, are gram-positive, facultatively anaerobic bacteria. The genus Streptococcus includes more than 20 species of microorganisms that can be pathogenic or opportunistic for humans.

Fecal streptococcus (lat. Streptococcus faecalis) is one of the representatives of the genus Streptococcus. This species is a conditionally pathogenic microflora of the intestines of humans and animals.

S. faecalis was first described in 1901, and its name comes from the Latin word “fecalis” (fecal), indicating its connection with the intestines.

The microorganism has a spherical shape and can range in size from 0.5 to 1.5 microns. It is highly resistant to various environmental factors such as temperature, pH and others. In addition, S. faecalis can survive in the acidic environment of the stomach and intestines, where it carries out its function.

In the human intestine, S. faecalis performs a number of functions, such as participation in digestion, maintenance of normal intestinal microflora, and protection against pathogenic microorganisms. It can also produce various enzymes, vitamins and amino acids, making it an important component of the intestinal microflora.

However, under certain conditions, S. faecalis can become pathogenic. For example, in people with weakened immune systems or in people taking antibiotics, this microorganism can cause various diseases such as urinary tract infections, abscesses, pneumonia, etc.

To prevent infections caused by S. faecalis, it is necessary to monitor hand hygiene, observe hygiene rules when using shared objects and tools, and also monitor your health.

Group d Streptococci are facultative anaerobic microorganisms. Family - enterococcaceae. Genus - Streptococcus. Species:

Streptococcus faecium is a microorganism with a protective capsule. The capsule consists of two types of polysaccharides. During the growth process, it is formed in the form of a chain - a ring in which the radial and middle walls intersect (form a diamond-shaped capsule). Found inside and outside the cell;

Streptococcus anginosus - in and around the cell (lipopolysaccharide). They can grow under anaerobic and aerobic conditions without the formation of pyocyanin or catalase. Green pigment and hemin breakdown products are often found. Proteus somatic O antigen is associated with a capsular polysaccharide. Some strains are sigmoids of the human flora. Group d differs from previous groups of embryos in both biochemical and antigenic properties.
