Streptococci are a genus of bacteria that includes many different species. They are gram-positive and nonmotile microorganisms that usually occur in long chains. Some types of streptococci can cause illness in humans, such as skin and soft tissue infections, urinary tract infections, and others.
Streptococci were discovered in 1881 by the German bacteriologist Robert Koch. He named them Streptococcus after the Greek word "streptos", which means "spiral". Currently, there are more than 200 species of streptococci, and they are widespread in nature.
Streptococcus bacteria are oval or round in shape and arranged in chains. They do not form spores and do not have flagella. Streptococci are anaerobic bacteria, meaning they cannot grow in the presence of oxygen.
Some types of streptococci are pathogenic for humans and cause various diseases. For example, Streptococcus pyogenes is the cause of many skin and soft tissue infections. Streptococcus pneumoniae causes respiratory tract infections such as pneumonia and sinusitis. Streptococcus agalactiae can cause infections in pregnant women and newborns.
Various methods are used to combat streptococci. For example, antibiotics are one of the most effective ways to treat streptococcal infections. Vaccines may also be used to prevent infections.
In general, streptococci are an important class of bacteria that can cause various diseases in humans. However, thanks to the development of science and medicine, we can fight these infections and keep people healthy.
Streptococci are a genus of bacteria in the Streptococcaceae family. Brief description Streptococci belong to the family of gram-positive, spherical, non-capsulated bacteria. Although all streptococci are monocultural in their biological properties, they can have different phenotypes and belong to
