|Illustrated in the upper image are tiny pinpoint 24-hour colonies recovered from one of the splenic abscesses. The wide zones of beta hemolysis are better seen in the close-in view of the 36 hour culture shown in the lower image. Streptococcus anginosus ("milleri" ) can be suspected if one of the following odors is detected:||View Page|

Piscitelli SC., Shwed J., Schreckenberger P., Danziger LH. Streptococcus milleri group: renewed interest in an elusive pathogen. European Journal of Clinical Microbiology & Infectious Diseases.11:491-8, 1992 The following review examines the bacteriological characteristics, epidemiology, pathogenicity and antimicrobial susceptibility of the "Streptococcus milleri group". "Streptococcus milleri group" is a term for a large group of streptococci which includes Streptococcus intermedius, Streptococcus constellatus, and Streptococcus anginosus. Usually considered commensals, these organisms are often associated with various pyogenic infections including cardiac, intra-abdominal, subcutaneous and central nervous system infections, particularly with the formation of abscesses. Organisms of the "Streptococcus milleri group" are often unrecognized pathogens due to the lack of uniformity in classifications and difficulties in microbiological identification. Penicillin G, cephalosporins, clindamycin and vancomycin all possess activity against these streptococci. Use of agents with poor activity may promote infections with "Streptococcus milleri group" and allow it to exhibit its pathogenicity. An understanding of these organisms may aid in their recognition and proper treatment.
Gelfand MS. Bakhtian BJ. Simmons BP.: Spinal sepsis due to Streptococcus milleri (anginosus): two cases and review. Reviews of Infectious Diseases. 13:559-63, 1991 We have recently cared for two patients with spinal sepsis secondary to infection with Streptococcus milleri (anginosus). One patient had a spinal epidural abscess and the other had meningitis as well as a spinal subdural empyema. A review of the English-language literature revealed only two previously reported cases of spinal epidural abscess due to S. milleri (anginosus) and no cases of spinal subdural empyema due to S. milleri (anginosus). We report two cases of spinal sepsis due to S. milleri (anginosus) and discuss pertinent literature.
