【 Principle 】

Pancreatic casein peptone and soy protein peptone provide the necessary substances for microbial growth; Sodium chloride maintains a balanced osmotic pressure; Phenylethanol can inhibit the growth of Gram negative bacteria such as Escherichia coli and Proteus; Fiber free sheep blood provides abundant nutrients; Agar is a coagulant used as a culture medium.

Main components

Composed of pancreatic casein peptone, soy protein peptone, sodium chloride, phenylethanol, defatted sheep blood, agar, and distilled water.

[Sample Requirements]

Samples such as feces and body fluids from the human body.

Clinical anaerobic bacteria isolation and screening: Anaerobic bacteria are isolated from pus, wounds, blood samples, and puncture fluids. Phenylethanol inhibits gram-negative bacteria and reduces interference from bacteria.

Purification of Gram positive anaerobic cocci/bacilli: Prioritize enrichment of pathogenic Gram positive anaerobic bacteria such as Streptococcus pyogenes, Propionibacterium, Clostridium perfringens, etc.

Identification of mixed infection specimens: Distinguishing Gram negative contaminating bacteria from pathogenic anaerobic bacteria in mixed infection samples of wounds and abdominal cavities to assist in determining the cause of infection.

Anaerobic bacterial colony counting: used for quantitative detection of anaerobic microorganisms in infected lesion specimens and disinfection equipment, to evaluate infection burden.

Pre isolation of anaerobic bacterial susceptibility: obtaining pure anaerobic single colonies, providing qualified isolated strains for subsequent anaerobic bacterial susceptibility testing

Streptococcus pyogenes

Gram positive anaerobic cocci parasitize mucous membranes and are commonly found in mixed infections; The colony is small, gray white, and raised smooth.

Clostridium perfringens, Clostridium difficile and other Clostridium genera

Gram positive anaerobic Bacillus subtilis has strong spore stress resistance and can cause trauma and intestinal infections; The colonies are grayish white and semi transparent, with some colonies spreading widely.

Propionibacterium acnes (Propionibacterium acnes)

Gram positive anaerobic short rod-shaped bacteria, resident on the skin, are prone to causing wound infections; The colony is small, porcelain white, and grows slowly.

Actinobacteria and Bacillus subtilis

Gram positive anaerobic bacteria without spores, pathogenic bacteria for chronic deep infections; The colony is small, solid in texture, white or light yellow in color.
