Only two patients had dental manipulation prior to the onset of sepsis, but each had received chemotherapy and 75% were granulocytopenic (PMN less than 500 … Alpha-hemolytic (viridans) streptococci are often isolated from cerebrospinal fluid (CSF); however, the significance of such isolates is poorly understood. In order to clarify the clinical significance of isolating these organisms from CSF, we did a retrospective analysis of 43 patients, from whom eight different species of alpha-hemolytic streptococci were recovered.

Alpha-hemolytic Streptococci (incomplete hemolysis or partial hemolysis) Alpha hemolytic streptococci are gram-positive, spherical, and non-motile organisms whose cells are organized in pairs or short chains. They are facultative anaerobes and form a characteristic α-hemolytic zone on blood agar plates.
