Streptococci are a diverse group of bacteria that are commonly found in the human body and other animals. They are characterized by their ability to form small, rod-shaped cells, and they are responsible for causing a wide range of diseases in humans, including strep throat, scarlet fever, and skin infections.
Streptococci are found in the throat and nose of healthy individuals, but they can become pathogenic when they enter the bloodstream or other body cavities. This can happen due to a variety of factors, including poor hygiene, injury, or underlying health conditions.
Streptococci are divided into two main groups based on their susceptibility to antibiotics: penicillin-sensitive streptococci and penicillin-resistant streptococci. Penicillin-sensitive streptococci are the most common type of streptococcus, and they are typically caused by Streptococcus pyogenes, the bacterium responsible for strep throat. Penicillin-resistant streptococci are less common, but they are responsible for a significant portion of the cases of scarlet fever and skin infections
