Alphahemolytic Streptococcus Pneumoniae On Blood Agar Stock Photo Edit Hydrogen peroxide but not pneumolysin causes the alpha hemolytic phenotype on blood agar plates. s. pneumoniae wt strains tigr4 (t), d39 (d), and ef3030 (e) or Δply and Δspxb Δlcto mutant derivatives, or s. mutans strain atcc 25175, were inoculated onto blood agar plates and incubated for 24 h at 37°c in a 5% co 2 atmosphere. another set of. Culture and sensitivity inoculate sample onto blood agar and chocolate agar plate. incubate at 37°c with 5 10% co 2 for 24 – 48 hours.; colony morphology. colonies on blood agar plate are small (0.5 mm), round, translucent, or mucoid with alpha hemolysis (a green discoloration of the agar around the colonies).

This test differentiates streptococcus pneumoniae from other alpha hemolytic streptococci. s. pneumoniae is sensitive to the chemical optochin (ethylhdrocupreine hydrochloride) and will be inhibited from growing around the optochin disk. 1. label half of a blood agar plate with your name. Bacteria included in the genus streptococcus are facultatively anaerobic, gram positive cocci. streptococci demonstrate different types of haemolysis on blood agar, which led to the distinction of beta and non beta haemolytic (alpha and gamma, i.e. non haemolytic) streptococci, corresponding to the pyogenic and non pyogenic groups, the later called also the viridians group streptococci (vgs) []. Pneumococcal infections.
