【 Principle 】

Peptone provides an organic nitrogen source, rich in amino acids, peptides, vitamins, and trace growth factors; Beef dipping powder provides carbon sources, nitrogen sources, minerals, and natural active growth factors, further enhancing the nutritional richness of the culture medium and promoting bacterial growth; Sodium chloride maintains the osmotic pressure of the culture medium; Agar is a coagulant.

Main components

Composed of peptone, beef extract, sodium chloride, agar, 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.

Hospital environmental monitoring: Sampling of surfaces such as wards, operating rooms, diagnosis and treatment areas, bed bars, etc., conducting microbial counts, and evaluating environmental hygiene conditions.

Disinfection effect verification: Compare the number of bacterial colonies on the surface before and after disinfection, test the cleaning and disinfection process, and evaluate the actual effectiveness of the disinfectant.

Medical device testing: Check the microbial contamination on the outer surface of reusable diagnostic and therapeutic equipment and medical devices to avoid the risk of cross infection.

Traceability of nosocomial infections: When clustered infections occur, sample and screen for surface microbiota, trace the source of contamination, and assist in nosocomial infection control.

Clean area quality control: Monitor the material table in special areas such as the laboratory, sterile preparation room, and pharmaceutical clean area to ensure that the operating environment meets the standards.

Daily routine sampling: Conduct regular sampling and testing according to standards, establish environmental hygiene baselines, and achieve long-term hygiene supervision.

Staphylococcus genus (Staphylococcus epidermidis, Staphylococcus aureus)

Gram positive cocci, mostly facultative anaerobic; Resistant to dryness and able to survive on dry surfaces for a long time; Staphylococcus epidermidis is a resident bacterium on human skin and has the highest detection rate on the surface; Staphylococcus aureus is a common opportunistic pathogen with moderate resistance.

Streptococcus

Gram positive cocci, facultative anaerobic; Without a special stress resistant structure, it has weak tolerance to dryness and physical and chemical factors, and often adheres to surfaces contaminated with human secretions.

Bacillus genus (Bacillus subtilis, Bacillus cereus)

Gram positive aerobic bacteria can form spores; Spores are resistant to dryness and conventional physical and chemical factors, with extremely strong survival ability, and widely exist in dust and crevices on the surface of objects.

Corynebacterium (Corynebacterium diphtheriae)

Gram positive bacteria, facultative anaerobic; The normal microbiota of human skin has weak adhesion and low resistance, and is generally scattered on the surface of various objects.

Enterobacteriaceae (Escherichia coli, Klebsiella, Proteobacteria, etc.)

Gram negative bacteria, facultative anaerobic; Not resistant to dryness, easily deactivated on dry surfaces, and can rapidly reproduce in humid environments; Mostly derived from sewage, excrement, and contaminated equipment, it is a common opportunistic pathogen.

Pseudomonas aeruginosa

Gram negative obligate aerobic bacteria; Prefers humid environments, has strong bacterial adhesion, is resistant to moisture and mild chemical irritation, and is frequently detected in sinks, pipelines, and wet countertops. It is a key monitoring bacterium for nosocomial infections.
