Streptococcus agalactiae Lehmann and Neumann
Culture medium Columbia blood plate (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 a test tube containing 5~10mL of liquid medium and 2 plates; (2) Open it in the safety cabinet, heat the tip of ampoule in a flame, quickly drop sterile water to creak it, then break it with forceps; (3) draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; (4) inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; ⑤ Put all the liquid test tubes and plates under the above culture conditions for cultivation, and the strains can be used when they grow.
Growth conditions 37 ℃,18-24h,5% CO2 + 95% air
Storage conditions 2-8 ℃
morphology Size: 1-2mm Shape: Round Edge: Neat Transparency: Opaque Color: light white uplift: middle convex surface: bright and smooth texture: moist and sticky
Separation substrate Human subject, blood and cerebrospinal fluid

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°C, 5% CO2, brain heart infusion medium, 18-24h. Brain heart infusion medium: brain infusion powder 5.0g, heart infusion powder 12.5g, peptone 5.0g, tryptone 10.0g, sodium chloride 5.0g, glucose 2.0g, disodium hydrogen phosphate 2.5g, agar 20.0g (not included in liquid medium), pH 7.4±0.2. Sterilize at 121°C for 15min.

Recovery steps:

(1) Prepare a test tube containing 5-10mL of liquid culture medium and 2 plates; 

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

(3) Draw 0.5mL of liquid culture medium into a freeze dried ampoule, fully rehydrate and transfer the solution to the liquid test tube, mix evenly; 

(4) Inoculate a plate with 0.2mL of suspension liquid, repeat the step to obtain two plates; 

(5) Put all the liquid test tubes and plates under the above culture conditions for cultivation, and the strains can be used when they grow.

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