Brief lecture video for nurses and nursing students on blood haemolysis classification of streptococci bacteria.
Beta Haemolytic Streptococci Colony Characteristics On Blood Agar Y Beta haemolytic colonies of staphylococcus aureus and streptococci on blood agar demonstrationbeta haemolytic colonies of staphylococci and streptococcibeta. Haemolysis of streptococci and its types with examples. Morphology. to identify s. pyogenes in clinical samples, blood agar plates are screened for the presence of β hemolytic colonies. the typical appearance of s. pyogenes colonies after 24 hours of incubation at 35 37°c is dome shaped with a smooth or moist surface and clear margins. A through h and k through v). rebecca lancefield, a prominent american microbiologist, introduced lancefield grouping. streptococcus as seen in scanning electron microscope. the basis of lancefield grouping is the antigenic differences in c carbohydrates, a group specific antigen. c carbohydrate is located in the cell wall of streptococci.

Beta haemolytic group a, c and g streptococcal infections. Beta haemolytic streptococci may be identified with a combination of disc identification tests, by serological grouping, pigment production and simple biochemical tests. colonies should be subcultured on blood agar to provide material for the determination of the carbohydrate antigen (lancefield group).
