Streptococcus bovis is the normal flora in the digestive tract of herbivores, common in the gastrointestinal tract and feces of cattle. It’s also a common bacteria in the human gastrointestinal tract, and can be isolated from gastrointestinal, feces, and the food. So, people always think it is harmless to many animals and human body. But many reports say it is related with infective endocarditis, colon cancer and urinary disease. Here we report one case of peritonsillar abscess and deep neck abscess caused by Streptococcus bovis infection.This patient was older, healthy, with acute onset of symptoms, and the infection was difficult to be controlled. Streptococcus bovis infection with throat and tonsil abscess is rarely reported. Because the acute respiratory problems caused by throat and neck infections is always life-threatening the doctors should pay attention to the infection.
