SubscribeFor isolation of specimens, giving detection of Pseudomonas sp. by colony colour
CHROMagar Pseudomonas can be used with pour or spread plate procedures: prepare CHROMagar Pseudomonas petri plates according to instructions, innoculate and incubate at 37șC for 48 hours.
Pseudomonas sp. develop as easily distinguishable blue-green coloured colonies, clearly visible under normal lighting conditions. Other bacterial species are inhibited or give colourless colonies. Pseudomonas aeruginosa, Pseudomonas fluorescens, Pseudomonas putida and Pseudomonas fragilis all give typical blue-green colony colouration and can be studied directly by serotyping or biochemical strip tests.
- Pseudomonas aeruginosa - Blue-green
- Pseudomonas fluorescens - Blue-green
- Pseudomonas putida - Blue-green
- Pseudomonas fragilis - Blue-green
- Other bacterial colonies - inhibited or colourless
