【 Principle 】

Multivalent peptone provides peptides, amino acids, and growth factors to meet the basic nutritional needs of harsh bacteria; Starch can neutralize toxic hydrogen peroxide released from the blood, adsorb inhibitory substances in the culture medium, and improve the survival rate of bacterial strains; Sodium chloride maintains osmotic pressure; Agar is a coagulant; DeFiberated sheep blood provides growth factors X and V for harsh bacteria such as Haemophilus and Neisseria.

Main components

Composed of multivalent peptone, starch, sodium chloride, agar, and defatted sheep blood.

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.

Primary isolation and cultivation of pathogenic bacteria under harsh conditions: specifically designed for cultivating difficult to culture bacteria such as Haemophilus influenzae and Neisseria gonorrhoeae that require X and V factors.

Routine bacterial screening of sterile specimens: Simultaneously detecting common bacteria and pathogenic bacteria from harsh conditions, achieving full microbial culture of clean specimens.

Respiratory infection pathogen detection: isolation of Haemophilus influenzae and Streptococcus pyogenes to assist in the diagnosis of respiratory infections such as pneumonia and pharyngitis.

Screening for urinary and reproductive tract infections: used for isolating Neisseria gonorrhoeae from cervical and urethral specimens and diagnosing gonorrhea.

Pure strain recovery and passage preservation: meet the purification, passage, and activity maintenance requirements of harsh bacteria such as Neisseria and Haemophilus.

Mixed low impurity bacterial infection specimen culture: The formula does not contain antibiotics, does not inhibit accompanying pathogenic bacteria, and avoids missed detection of mixed pathogens.

Neisseria gonorrhoeae and Neisseria meningitidis: Streptococcus pyogenes, obligate aerobic, with extremely high nutritional requirements; The colony is small, smooth, and semi transparent like dewdrops.

Haemophilus influenzae: Streptococcus pneumoniae, facultative anaerobic, requires X+V factor; The colony is small, colorless and transparent, and grows in a satellite shape near the site of Streptococcus pyogenes.

Streptococcus pneumoniae, Streptococcus pyogenes: Streptococcus pyogenes, facultative anaerobic; The colony is small, with visible alpha/beta hemolytic rings.

Staphylococcus: Staphylococcus aureus, resistant to dryness; The colony is round and raised, milky white or golden yellow, opaque.

Enterobacteriaceae (Escherichia coli, Klebsiella): G ⁻ facultative anaerobic bacteria; Medium sized colony, moist gray white.

Pseudomonas aeruginosa: G-specific aerobic, hygroscopic; Flat colonies produce green pigments with a unique odor.
