Escherichia colifor coliformsfeces

Coliform bacteria are présent in the environment and feces of all warm-blooded animais and humans. Coliform bacteria are unlikely to cause illness. However, their presence in drinking water indicates that disease-causing organisms (pathogens)could be in the water System. Instructions&lnterpretation of inspection results 1. Open the bag and add 2ml water sample (for tableware, an appropriate amount of purified water can be used to wipe the surface of the tableware, leaving 2ml of the wiping solution),allowing the water sample to fully wet the paper and then seal the bag. 2. Place the paper fiat and let it sit for 48 hours at around 25°C or 24 hours at 37°C.Observe the results. 1. During the testing period, if yellow spots are found on the paper or ail the paper turns yellow, it is considered positive, indicating that the sample contains a coliform group. 2. If it displays purple red, it is negative, indicating that the sample does not contain coliform bacteria. What should be done if the test is positive? Add bleach to the sample then pour it into the toilet. Thoroughly wash hands. For positive water samples, please conduct further bacterialidentification (physiological and biochemical experiments or nucleic acid sequencing). [IMPORTANT] 1. The paper should be stored dry and away from light to avoid product deterioration and affecting the test results. 2. If there is discoloration or moisture absorption on the appearance of the paper, it should be stopped from use to avoid false positive results. 3.The pH value of the test sample should be neutral. If the pH value is too low or too high, it will affect the test. [STORAGE] Store in a dry place at 2°C to 30°C,
