Product Overview

【 Principle of Inspection 】

Cow brain extract powder, cow heart extract powder, pancreatic peptone, and casein peptone are used as the basic nutrients in the culture medium, providing the carbon and nitrogen sources, vitamins, and other growth factors required for bacterial growth; Sodium dihydrogen phosphate as buffer: glucose as fermentable carbon source; Sodium chloride maintains the osmotic pressure required for the normal growth of bacterial cells; Agar is a coagulant for culture media.

Main components

Composed of bovine brain extract powder, bovine heart extract powder, tryptone, casein peptone, sodium chloride, glucose, disodium hydrogen phosphate, and agar.

Storage conditions and expiration date

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

This product is a disposable product.


Clinical application scenarios

Isolation and cultivation of harsh culture bacteria: used for the initial isolation of pathogenic bacteria with high nutritional requirements such as Streptococcus, Neisseria, and Haemophilus, to compensate for the nutritional deficiencies of ordinary agar.

Clinical specimen microbiological testing: bacterial culture of sterile/infectious specimens such as blood, cerebrospinal fluid, pus, and wound secretions to assist in the diagnosis of systemic and local bacterial infections.

Purification and passage preservation of bacterial strains: Purification, recovery, and short-term preservation of various standard strains and clinically isolated strains to maintain their activity.

Hemolysis test and biochemical screening: observe hemolytic reactions of streptococcus, Listeria monocytogenes, etc., and complete preliminary identification of bacterial strains based on colony characteristics.

Aseptic and disinfection effectiveness verification: Microbial counting of medical devices, biological samples, and disinfected items, detecting common bacteria and harsh bacteria contamination.

Cultivation of anaerobic bacteria and facultative anaerobic bacteria: Used in conjunction with anaerobic environments, it supports the growth of most facultative anaerobic and microaerophilic pathogenic bacteria.


Introduction to the Relevant Microbiological Characteristics

Staphylococcus aureus: G+cocci, facultative anaerobic, drought resistant; The colony is plump and protruding, milky white/golden yellow, smooth and opaque.

Streptococcus (Streptococcus pyogenes, Streptococcus pneumoniae): G+cocci, facultative anaerobic, high nutritional requirements; The colony is small and translucent, with visible alpha/beta hemolytic rings.

Enterobacteriaceae genus: G - facultative anaerobic bacteria, wet loving but not dry tolerant; The colony is medium-sized, moist gray white, and partially migrates and spreads.

Pseudomonas aeruginosa: G-specific aerobic, easy to colonize in damp conditions; Flat colonies produce green water-soluble pigments with a unique ginger aroma.

Neisseria gonorrhoeae (Neisseria gonorrhoeae, Neisseria meningitidis, Clostridium difficile): G - cocci, high nutritional requirements, high nutritional needs; The colony is small and smooth, resembling dewdrops.
