Streptococcus anginosus group (SAG) organisms are common colonizers of the oropharyngeal, intestinal, and genitourinary mucosa, but are increasingly recognized as human pathogens. This part IIIa describes the epidemiology of SAG infections and the characteristics of those located in the head and neck. Its ability to form abscesses is widely known, particularly, in the head and neck area; odontogenic, periorbital and brain abscesses stand out. They also cause sinusitis, eye infections, epidural abscesses, Lemierre’s syndrome, subdural empyemas, and collections in the skin and soft tissues and bones of the skull. Its role in pharyngitis is controversial, although some of the subspecies could be involved in such infections. Its carcinogenic potential is also postulated given its association with oropharyngeal, gastric or esophageal carcinomas..
