【 Principle of Inspection 】

Beef paste and peptone provide amino acids, peptides, vitamins, and nitrogen sources; Sodium chloride maintains the osmotic pressure of the culture medium; Hexadecyltrimethylammonium bromide

As a selective inhibitor, it has strong inhibitory effects on gram-positive bacteria such as Staphylococcus, Streptococcus, and Bacillus, as well as other gram-negative bacteria such as Escherichia coli and Salmonella; Agar is a coagulant.

Main components

Composed of beef paste, peptone, sodium chloride, hexadecyltrimethylammonium bromide, and agar.

Isolation and identification of Pseudomonas aeruginosa from clinical specimens: selective screening of Pseudomonas aeruginosa in wound, sputum and other specimens to assist in the diagnosis of respiratory, wound and urinary tract infections.

Hospital environment infection monitoring: Screening for Pseudomonas aeruginosa colonized in humid environments such as operating rooms, water tanks, and humidification bottles to control cross infection within the hospital.

Microbial testing of medical equipment and consumables: detecting copper contamination in flushing solutions, dressings, dialysis consumables, etc., to ensure the safety of sterile medical items.

Microbial limit test for drugs and disinfectant rinse solutions: Special screening for Pseudomonas aeruginosa in water-based drugs and skin rinse solutions, in compliance with pharmacopoeia control requirements.

Purification of contaminated bacterial strains: Separate a single Pseudomonas aeruginosa colony from a mixed bacterial specimen for subsequent biochemical identification and drug sensitivity testing.

Traceability investigation of outbreak infection: In the case of concentrated copper green infection, multiple sampling points are taken from water sources, equipment, and the environment to trace the source of pollution.

Pseudomonas aeruginosa (Pseudomonas aeruginosa)

Biological characteristics

G ⁻ obligate aerobic bacteria, single ended single flagella, active in movement; Moisturizing, can produce water-soluble pigments such as pyocyanin and fluorescein; Tolerant to a certain concentration of CTAB is a common pathogenic bacterium in hospitals, which can cause infections in wounds, urinary tract, respiratory tract, and wounds.

Characteristics of bacterial colonies

Medium sized, flat, with irregular edges, yellow green/green water-soluble pigments diffuse from the culture medium around the colony; Typical ginger like special odor; Some strains produce fluorescein, and yellow green fluorescence can be seen under ultraviolet light; The surface is moist and smooth.
