| Illustrated in the upper photograph 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 photograph.
Streptococcus milleri (anginosus) can be suspected if one of the following odors is detected: | View Page |
| Most strains of S. milleri (anginosus) carry the F antigen (see photograph). Rare strains that carry the group A antigen can be differentiated from S. pyogenes by which of the following laboratory tests: | View Page |
| S. milleri CO2 Enhanced growth under CO2 incubation is an additional clue to the identification of S. milleri.Note in the photograph the increased growth of the colonies grown on the plate incubated under CO2, compared to those incubated in ambient air (O2). | View Page |
| S. milleri Biochemicals The combination of decarboxylation of arginine (red color in the 2nd tube from left compared to the yellow color of the control to its left), the hydrolysis of esculin (black pigment in the esculin agar tube) and the reduction of nitrates to nitrites (red color in last tube on the right) are biochemical characteristics confirmatory for S. milleri (anginosus). | View Page |
| Most infections caused by S. milleri (S. anginosus) can be effectively treated with penicillin or a first generation cephalosporin. | View Page |

Spinal sepsis due to Streptococcus milleri: two cases and review.
Reviews of Infectious Diseases. 13:559-63, 1991We have recently cared for two patients with spinal sepsis secondary to infection with Streptococcus milleri.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 and no cases of spinal subdural empyema due to S. milleri. We report two cases of spinal sepsis due to S. milleri and discuss pertinent literature. | View Page |
| The epidural and subdural abscesses in the two patients reported by Gelfand, et al, are clinical manifestations uncommon for S. milleri. | View Page |
