Shigella dysenteriae

Culture medium	Nutritional gravy medium (NA/NB): beef paste 3.0g, peptone 10.0g,NaCl 5.0g, agar 20.0g (without liquid medium), distilled water 1.0L,pH 7.0. Sterilization at 121 ℃ for 15min. [Note] Adding 5 mg MnSO4 · H2O to culture Bacillus is beneficial to produce spores.
Subculture procedure	(1) Prepare a test tube containing 5~10mL of liquid medium and 2 plates; (2) open it in the biosafety cabinet, heat the tip of ampoule in the flame, quickly drop sterile water to creak it, and 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	30 ℃;18-24 hours; Aerobic
Growth characteristics	Gram-negative bacilli, no movement, no capsule, no spore formation, no acid resistance. Aerobic and facultative anaerobic, well grown on simple nutrient medium. It is the pathogen of bacillary dysentery, which can cause bloody diarrhea. People and other large primates are the only natural hosts. Most infections are transmitted in a human-to-human manner, but ingestion of contaminated water or food can also cause infection. Serotype: A5.
Storage conditions	2-8 ℃
morphology	G-bacilli size: 1-2mm shape: round edge: neat transparency: opaque color: light yellow uplift: middle convex surface: bright and smooth texture: moist
application	Research, "Quality Requirements of GB 4789.28 Medium and Reagents" Standard Strain.
Sharing mode	Public welfare sharing
