Cardiobacterium hominis

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 1-2 pieces of the plate; (2) sterilizing the surface of the plate, open it in the biosafety cabinet; (3) suck 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 bacterial suspension; (4) suck the bacteria suspension with a pasteur pipette, transfer it into a fresh plate, and spread it evenly; (5) Place the plate under the above culture conditions and culture
Growth conditions	37 ℃;48-72h;5% CO2
Storage conditions	2-8 ℃
morphology	Size: 1-2mm Shape: Round Edge: Irregular Transparency: Opaque Color: White Protuberance: Middle Protuberance Surface: Bright and Smooth Texture: Wet and Easy to Stir

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 24-48hours.
Recovery record: According to the recovery instructions, the results of the recovery are reported as follows:
