【 Principle 】

Tryptone and soy peptone provide carbon and nitrogen sources, as well as other substances required for microbial growth; Sodium chloride maintains osmotic pressure; Glucose is a fermentable sugar that provides a carbon source; Potassium dihydrogen phosphate provides a buffer system; Tween 80 and lecithin can neutralize quaternary ammonium compounds and parabens.

Main components

Composed of tryptone, soy peptone, sodium chloride, dipotassium dihydrogen phosphate, glucose, lecithin, Tween 80, agar, and distilled water.

[Sample Requirements]

Indirect samples from the human body.

Disinfection effect monitoring: detecting microorganisms on the surface of disinfected objects and medical equipment, objectively evaluating the effectiveness of disinfection measures.

Monitoring of hospital physical environment: Sampling of wards, operating rooms, diagnosis and treatment desks, door handles, and other areas for microbial counting and contamination assessment.

Reusable instrument contamination detection: Check the cleaned and disinfected diagnostic and therapeutic instruments, endoscopes, pipelines, etc., and control the hygiene quality of the instruments.

Neutralizer verification test: used for identifying the neutralization effect of disinfectants and verifying whether the neutralization system of the culture medium meets the regulatory requirements.

Traceability investigation of nosocomial infections: When clustered infections occur, samples of relevant environments and items are taken to trace the source of pollution.

Medical item sampling: detecting microbial contamination of disinfected dressings, containers, cleaning tools, etc.

Staphylococcus aureus: Gram positive cocci, facultative anaerobic, drought resistant; The colony is round and protruding, opaque, and appears grayish white or golden yellow.

Streptococcus: Gram positive cocci, facultative anaerobic, with weak resistance to the outside world; The colony is small, gray white and semi transparent.

Bacillus: Gram positive aerobic bacteria that can form spores, resistant to dryness and disinfectants; The colony size is relatively large, the texture is rough, and the edges are not neat.

Rod shaped bacteria: Gram positive bacteria, facultative anaerobic, with weak resistance; The colony is small and gray white in color.

Enterobacteriaceae: Gram negative bacteria, facultative anaerobic, intolerant to dryness and preferring moisture; The colonies are of medium size, moist gray white, and some strains are prone to spreading and spreading.

Pseudomonas aeruginosa: Gram negative obligate aerobic bacteria, prefers moisture and has strong adhesion; The colony is flat, producing green pigment and accompanied by a special odor.
