Clinical application scenarios

Aseptic inspection: used for sterile testing of sterile drugs, medical dressings, disposable medical devices and other products to determine the presence of microbial contamination.

Environmental monitoring: Sampling and counting of object surfaces, airborne bacteria, and planktonic bacteria in hospital diagnosis and treatment areas, pharmaceutical clean areas, and laboratories to evaluate environmental hygiene and cleanliness levels.

Equipment contamination testing: Screening for aerobic and facultative anaerobic bacteria on the surface of reused and various medical equipment to reduce the risk of cross infection.

Microbial isolation and counting: perform primary bacterial isolation, purification, and quantitative colony counting on clinical and environmental samples.

Validation of disinfection and sterilization effect: detect the survival of microorganisms before and after disinfection and sterilization, and evaluate the effect of disinfection and sterilization process and disinfectant.

Culture and preservation of bacterial strains: used for passaging, purification, and short-term preservation of standard strains and clinically isolated strains.


Introduction to the Relevant Microbiological Characteristics

Staphylococcus

Gram positive cocci, facultative anaerobic, drought resistant; The colony is round and protruding, opaque, gray white or golden yellow, with neat edges.

Streptococcus

Gram positive cocci, facultative anaerobic, intolerant to dryness and physical and chemical stimuli; The colony is small, gray white and semi transparent, with a smooth surface.

Bacillus

Gram positive aerobic bacteria can form spores and have strong resistance to dryness and stress; The colony is relatively large, flat and rough, gray white, with irregular edges.

Enterobacteriaceae

Gram negative bacteria, facultative anaerobic, intolerant to dryness, prefers humid environments; The colony is of medium size, gray white and moist, and the Proteobacteria colony is prone to spreading and spreading.

Pseudomonas aeruginosa

Gram negative obligate aerobic bacteria, prefer moisture and have strong adhesion; The colony is flat and produces green pigment, accompanied by a special odor.

yeast

Single celled fungi, facultative/obligate aerobic, prefer moisture; The colony is round and raised, cheese like, white or light red in color.

Filamentous mold

Specialized aerobic, spores resistant to dryness, often transmitted through air; The colony is fluffy/flocculent, with rich color and easy to spread outward
