Streptococcus Equi
Streptococcus equi is a species of gram-positive, facultative anaerobic, coccus-shaped bacteria in the genus Streptococcus. It is an important pathogen of horses and other equids, causing strangles, a contagious and often fatal disease. S. equi is also an opportunistic agent of human infection, including pneumonia, septicemia, and brain abscess. It is becoming increasingly important as a cause of endocarditis, as well as in other forms of infection, such as septic arthritis, bacteremia, and osteomyelitis. In animals, S. equi is highly contagious and can spread rapidly throughout a population by contact. Vaccines are available to reduce the risk of infection and limit its spread in susceptible hosts. In humans, the organism can be acquired through contact with infected animals, contaminated environments, and direct contact with infected humans or their secretions. Streptococcus equi can be detected in laboratory settings through culture, PCR testing, and a variety of other methods. Its detection and control is essential for the prevention of disease in horses and other equids, as well as humans.
