II. Pathophysiology
-
Streptococcus Viridans are a heterogeneous group
- Alpha-hemolytic Streptococcus (Gram Positive Cocci)
- Viridans is named for the greenish glow on Blood Culture media (alpha-hemolytic effects on RBCs)
- Subdivided into at least 4 sub groups (see below)
- Normal human colonization
- Gastrointestinal Tract
- Oropharynx
- Human Infections
- Subacute Bacterial Endocarditis
- Extracellular Dextran allows binding to Heart Valves (Streptococcus Viridans, Group D Strep, Enterococcus)
- Dental Infections (esp. Streptococcus Mutans)
- S. mutans binds teeth and ferments sugars to acids, leading to dental decay
- Abscesses
- Streptococcus Anginosus Group (intermedius) are normal, microaerophilic flora in the Gastrointestinal Tract
- Brain and Liver Abscesses
- Streptococcus Anginosus Group either alone or in mixed Bacterial Infections with Bacteroides
- Patients may present with Occult Bacteremia
- Subacute Bacterial Endocarditis
III. Types
- Streptococcus Mutans Group
- Streptococcus Mutans
- Streptococcus sobrinus
- Streptococcus criceti
- Streptococcus rattus
- Streptococcus downei
- Streptococcus macacae
- Streptococcus Mitis Group
- Streptococcus Mitis
- Streptococcus sanguis
- Streptococcus parasanguis
- Streptococcus gordonii
- Streptococcus crista
- Streptococcus infantis
- Streptococcus oralis
- Streptococcus peroris
- Streptococcus Salivarius Group
- Streptococcus Salivarius
- Streptococcus vestibularis
- Streptococcus thermophilus
- Streptococcus Anginosus Group (Streptococcus Milleri Group, Intermedius group)
- Streptococcus Anginosus
- StreptococcusConstellatus
- Streptococcus Intermedius

| Definition (NCI) | A species of facultatively anaerobic, Gram positive, cocci shaped bacteria in the phylum Firmicutes. This species is positive for arginine deamination, esculin hydrolysis and beta glucosidase and negative for urease, catalase, sialidase and hyaluronidase. It can ferment amygdalin, lactose, salicin, cellobiose, trehalose and raffinose but not arabinose, glycerol, inulin, sorbitol, mannitol or ribose. S. anginosis is found in normal human urogenital and gastrointestinal tracts and is involved in opportunistic infections of abscesses. |

| Definition (NCI_CDISC) | Any bacterial organism that can be assigned to the species Streptococcus intermedius. |
| Definition (NCI) | A species of facultatively anaerobic, Gram positive, cocci shaped bacteria in the phylum Firmicutes. This species is positive for arginine deaminase, esculin hydrolysis, hyaluronidase, sialidase, beta galactosidase and beta glucosidase and negative for urease and catalase. It can ferment lactose and trehalose but not arabinose, glycerol, inulin, sorbitol, raffinose or mannitol. S. intermedius is a commensal organism in humans that can be an opportunistic pathogen causing brain and liver abscesses, periodontitis and purulent infections. |
| Definition (MSH) | A species of gram-positive bacteria in the STREPTOCOCCUS MILLERI GROUP. It is commonly found in the oropharynx flora and has a proclivity for abscess formation, most characteristically in the CENTRAL NERVOUS SYSTEM and LIVER. |

| Definition (NCI) | A non taxonomic grouping of species within the Streptococcus genus that are alpha hemolytic and do not express Lancefield antigens. |
| Definition (MSH) | A large heterogeneous group of mostly alpha-hemolytic streptococci. They colonize the respiratory tract at birth and generally have a low degree of pathogenicity. This group of species includes STREPTOCOCCUS MITIS; STREPTOCOCCUS MUTANS; STREPTOCOCCUS ORALIS; STREPTOCOCCUS SANGUIS; STREPTOCOCCUS SOBRINUS; and the STREPTOCOCCUS MILLERI GROUP. The latter are often beta-hemolytic and commonly produce invasive pyogenic infections including brain and abdominal abscesses. |
