Streptococcus pyogenes
Culture medium Columbia blood plate (English name: CA-B): casein pancreatin digest 10.0g, cardiopancreatin digest 3.0g, corn starch 1.0g, meat gastric enzyme digest 5.0g, yeast extract 5.0g, sodium chloride 5.0, agar 20.0g, distilled water 1.0L,pH 7.3±0.2. After sterilization at 121 ℃ for 15min, cool to 55 ℃, add 5% sterile defibrated sheep blood, shake well, pour the plate and cool it for later use.
Subculture procedure (1) Prepare 1-2 pieces of the plate; (2) sterilize the surface of the plate and open it in biosafety cabinet; (3) Absorb 1-3ml of sterile water into the plate, scrape the bacterial lawn back and forth on the surface of the plate with a sterile spreader to make a bacterial suspension; (4) suck the bacteria suspension with a pasteur pipette, dispense it into a fresh plate  evenly. (5) put the plates under the growth conditions.
Growth conditions 37 ℃;18-24h;5% CO2
Storage conditions 2-8 ℃

Receiving notice: if any abnormality is found on the day of receipt, please contact the customer service within 24 hours. If it is overdue, it is deemed that the bacteria are well. The freeze dried culture shall be used up once and shall not be retained. The bacterial viability will resume after 1-2 generation of recovery and can be used normally. Handling instructions of agar slant and suspension liquid is enclosed. Please operate in strict accordance with this instruction, otherwise the replacement of bacteria are not be available in case of aberrant growth and loss of viability.

Growth conditions:37 ℃,5% CO2, Columbia blood plate (ready-to-use type),18-24h.

Recovery steps:

(1)Prepare 1-2 of above mentioned plates; 

(2)Open it in the biosafety cabinet, sterilize of the ampoule, heat the tip in a flame, quickly drop sterile water to creak it, then break it with forceps; 

(3)Draw 0.5ml of sterile water into the freeze dried ampoule, make it fully dissolved, and distribute the solution to the plates well in 200ul/plate; 

(4)Put the plates under the above culture conditions for cultivation for 18-24hours.

Recovery record:  According to the recovery instructions, the results of the recovery are reported as follows:

Item test results
viability good viability, in 24 hours strain layer become obvious,  colony is typical
colony morphology:

Size: 1-2mm Shape: Round Edge: Neat Transparency: Opaque

Color: off-white uplift: middle convex surface: bright and smooth texture: moist and easy to stir

Conclusion: good viability, no abnormal colony morphology, qualified
