strep

Strep, short for streptococcus, is a genus of gram-positive, spherical bacteria that are part of the normal flora of the human body. They are typically found in the throat, nose, and skin. Streptococcus bacteria can cause a variety of infections, both in humans and animals. The term "strep" is often used colloquially to refer to strep throat, a common bacterial infection caused by group A streptococcus (GAS). Symptoms of strep throat include sore throat, fever, headache, and swollen lymph nodes. It is typically treated with antibiotics, such as penicillin or amoxicillin.

Streptococcus bacteria can also cause other types of infections, including skin infections, pneumonia, and necrotizing fasciitis. In animals, strep infections can cause mastitis in dairy cows and canker in horses. The bacteria can be transmitted through direct contact with an infected person or animal, or through contaminated surfaces or objects.

Prevention of strep infections involves good hygiene practices, such as washing hands frequently and avoiding close contact with infected individuals. Vaccines are available for some types of strep infections, such as pneumococcal disease and meningitis. Early diagnosis and treatment of strep infections are important to prevent complications and reduce the risk of antibiotic resistance.
