A common etiology of diabetic ketoacidosis is severe infection [1], and hyperglycemia has been reported to be a possible risk factor for developing a liver abscess [2]. Streptococcus anginosus is a subgroup of streptococcus viridians, which commonly exists in normal oral and gastrointestinal flora. Streptococcus anginosus differs from other bacterial subgroups as Streptococcus anginosus may cau...

Based on a pair of primers developed initially for differentiating the anginosus group from other viridans streptococci, the PCR reported here can also differentiate between members of the anginosus group and Streptococcus dysgalactiae subsp. equisimilis among beta-hemolytic group C and G streptococci. The resulting 742-bp PCR product was specific for members of the anginosus group, although a ...

INTRODUCTION Bacterial infections may appear as sequelae of remote tuberculous infections, especially thoracic infections. The simultaneous appearance of tuberculosis and bacterial infection is not common, and, to our knowledge, the association of infection by Streptococcus anginosus and Mycobacterium tuberculosis has not been reported previously in the literature. CASE PRESENTATION We report...

Difficulties in distinguishing organisms of the "Streptococcus milleri group" (SMG; Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus), have caused ambiguity in determining their pathogenic potential. We reviewed 118 cases in which SMG isolates had been identified using 16S rDNA sequence. S. constellatus and S. anginosus were isolated far more frequently than wa...

conclusions it should be kept in mind that the oral flora bacterium s. anginosus may cause transient bacteremia and deep-seated organ abscesses in immunodeficient patients with poor oral hygiene. such patients with intra-abdominal abscesses should be treated with antibiotics and surgery. introduction the streptococcus anginosus group of bacteria are low-virulence bacteria existing as commensals...

OBJECTIVE To assess the significance of the Streptococcus anginosus group in intracranial complications of pediatric patients with rhinosinusitis. DESIGN Retrospective cohort study. SETTING Tertiary pediatric hospital. PATIENTS A 20-year review of medical records identified patients with intracranial complications resulting from rhinosinusitis. In the 50 cases identified, S anginosus was ...

A 35-year-old man was found to have a cerebral abscess secondary to a recurrent sigmoid diverticular abscess. Both cultures grew Streptococcus anginosus. Brain abscess is a rare but potential complication of sigmoid diverticulitis. Streptococcus anginosus, which is found in human gut flora, is a common cause of brain abscess.

We report a case of splenic abscess with multiple brain abscesses caused by Streptococcus intermedius in a healthy young man without any identifiable risk factors, which resolved with percutaneous drainage and antibiotics. Streptococcus intermedius, a member of the Streptococcus anginosus group, is a common commensal organism of the oral cavity and gastrointestinal tract, and it is a known caus...

Streptococcus anginosus is part of the normal flora of the human gastrointestinal tract. Their ability to cause abscesses is very unique and sets them apart from the rest of the streptococci groups. While an association of group D streptococcus bacteremia and endocarditis with colorectal carcinoma is well established, S. anginosus infections are rarely implicated with colonic malignancy. We pre...
