Growth at 42°C Test- Principle, Procedure, Result, Uses


The growth at 42°C test is a simple and rapid test that can help in the identification of some bacteria based on their ability to grow at a high temperature. The test is especially useful for the differentiation of Pseudomonas aeruginosa from other fluorescent pseudomonads, as well as other non-fermentative bacteria. Pseudomonas aeruginosa is a Gram-negative rod that can cause serious infections in humans, especially in immunocompromised patients and those with cystic fibrosis. The organism is also known for its resistance to many antibiotics and disinfectants, making it difficult to treat and control. Therefore, it is important to identify P. aeruginosa accurately and promptly in clinical specimens.
