Alpha hemolytic streptococci

Viridans streptococci are a heterogeneous group of α-hemolytic and nonhemolytic streptococci that are constituents of the normal flora of the respiratory and gastrointestinal tracts of infants, children, and adults. From: Infectious Diseases of the Fetus and Newborn (Seventh Edition), 2011. Related terms: Penicillin Alpha Hemolytic Streptococcus. Viridans streptococci are part of a normal oral flora and generally gain access to the bloodstream through breaches in the oral mucosa (in dental surgical procedures, for example). The aerobic culture grew few alpha-hemolytic streptococci, occasional beta-hemolytic streptococci (not group A or B), rare Staphylococcus aureus, and rare Candida albicans. Bilateral peritonsillar abscesses: a challenging diagnosis (redirected from alpha-hemolytic Streptococcus) Also found in: Dictionary , Thesaurus . Related to alpha-hemolytic Streptococcus: Streptococcus viridans , beta-hemolytic streptococci Abstract After introduction of selective decontamination of the digestive tract (SDD), a change toward an increase of infections by Staphylococcus epidermidis and alpha-hemolytic Streptococci has been noticed in the predominant etiology of infections [ncbi.nlm.nih.gov] Alpha-hemolytic Streptococci.

The viridans streptococci are a large group of commensal bacteria that are either alpha-hemolytic, producing a green coloration on blood agar plates (hence the name "viridans", from Latin vĭrĭdis, green), or nonhemolytic. They possess no Lancefield antigens. Beta-hemolytic Tano and colleagues have shown that the alpha-hemolytic streptococci from children with RAOM are less effective at inhibiting middle ear pathogens than those from children without otitis media [37]. The Adenoid Microbiome in Recurrent Acute Otitis Media and Obstructive Sleep Apnea Alpha-hemolytic Streptococci Alpha-hemolysis (α-hemolysis) is a partial or “green” hemolysis associated with reduction of red cell hemoglobin.

The UniGoldTM Streptococcus pneumoniae urinary antigen

Streptococcus pneumoniae and a group of oral streptococci (Streptococcus viridans or viridans streptococci) display alpha-hemolysis. Alpha-hemolysis is also termed The alpha hemolytic strep group includes strains that cause many diseases of the mouth, ears, and respiratory system. Diseases ranging from tooth decay to ear infections to strep pneumonia and alpha-hemolysis (green) (Figure 1). The alpha-hemolytic property differentiates this organism from many species, but not from the commensal alpha-hemolytic (viridans) streptococci. Differentiating pneumococci from viridans streptococci is difficult as young pneumococcal colonies appear raised, similar to viridans streptococci.

When alpha-hemolysis (α-hemolysis) is present, the agar under the colony will appear dark and greenish due to the conversion of hemoglobin to green biliverdin. Streptococcus pneumoniae and a group of oral streptococci (Streptococcus viridans or viridans streptococci) display alpha-hemolysis.

This group is very common. Many strains live naturally in humans causing no symptoms.

Alpha-hemolysis (α-hemolysis) is a partial or “green” hemolysis associated with reduction of red cell hemoglobin. Alpha hemolysis is caused by hydrogen peroxide produced by the bacterium, oxidizing hemoglobin to green methemoglobin. It exhibit incomplete haemolysis with 1-2 mm wide.

Alpha-hemolytic streptococci are very difficult to identify by phenotypic methods. In this study, a pyrosequencing method for the identification of streptococcal species based on two variable regions of the 16S rRNA gene is described. Almost all studied streptococcal species ( n = 51) represented by their type strains could be differentiated except for some closely related species of the Streptococci of the alpha group (e.g., the viridans and S. pneumoniae) cause some destruction (hemolysis) of red blood cells. The beta group are more destructive of red blood cells; they also produce toxic substances that affect white blood cells and the clotting properties of blood. Streptococci that partially lyse red blood cells cultured on a blood agar medium, producing a green color around the cell colonies. Alpha-hemolytic streptococci (commonly called viridans streptococci) are surrounded by green discoloration resulting from incomplete hemolysis.

Most strains of S. pneumoniae are alpha- Jan 31, 2016 When urine culture revealed a “significant” bacteriuria of >105 cfu/ml with α- hemolytic streptococci (Streptococcus viridans group) she was Alpha hemolytic organisms (Streptococcus pneumoniae and Streptococcus mitis) (optochin sensitive) from other a-hemolytic streptococci (optochin resistant).
