【 Principle 】

Peptone and beef extract provide comprehensive nitrogen sources and growth factors such as amino acids, peptides, vitamins, and growth factors; Glucose is a fermentable carbon source; Sodium chloride creates a physiological isotonic environment.

Main components

Composed of peptone, beef extract, glucose, sodium chloride, and distilled water.

Storage conditions and expiration date

Storage conditions: This product should be stored in a dark environment at 2-8 ℃.

Validity period: The unopened original packaging has a validity period of 6 months.

This product is a disposable product.

Blood specimen enrichment culture: used as a basic culture medium for clinical blood culture, glucose provides energy, and promotes the recovery and proliferation of low concentration pathogenic bacteria in the blood.

Aseptic examination of body fluids: Aseptic screening of puncture specimens such as pleural fluid, ascites, cerebrospinal fluid, and pus, with enrichment of trace pathogenic microorganisms.

Intensive cultivation of pathogenic bacteria with high nutritional requirements, such as Streptococcus, Neisseria, and Haemophilus, to supplement the nutritional deficiencies of ordinary meat broth.

Strain preservation and passage: Short term activation and passage preservation of standard strains to maintain their vitality.

Microbial biochemical pre culture: Prepare fresh homogeneous bacterial solution for subsequent biochemical identification and bacterial enrichment before drug sensitivity testing.

Aseptic inspection of drugs and medical devices: As a universal bacterial enhancement solution, it detects contaminated aerobic and facultative anaerobic bacteria and yeast in samples.

Escherichia coli

Gram negative short rod-shaped bacteria with flagella, motile, non spore forming, facultative anaerobic; It can rapidly ferment glucose to produce acid and gas, and has a fast reproduction rate. After cultivation, the broth becomes uniformly turbid, making it a common pathogenic bacterium in blood and body fluids.

Klebsiella and Escherichia genera

Gram negative crude short rod-shaped bacteria, mostly without flagella, with capsules, facultative anaerobic; The rapid proliferation of glucose often leads to postoperative infections and fluid contamination.

Pseudomonas aeruginosa

Gram negative bacteria, with a single flagellum at one end, specifically aerobic; Decomposing glucose, it often forms a bacterial film on the surface of liquids, and some strains produce water-soluble green pigments, which are commonly found in wound and drainage fluid specimens.

Salmonella and Proteobacteria

Gram negative bacteria, with flagella around the body, active motility, and facultative anaerobic; It grows vigorously in an environment with sufficient glucose and is prone to appear in fecal and pus specimens.

Staphylococcus aureus

Gram positive cocci, arranged in clusters of grapes, without spores, facultative anaerobic, salt tolerant; Fermented glucose produces acid, which is the primary pathogenic bacterium for sepsis and skin infections, and grows rapidly in meat broth.
