Presence of B. coil or E. coil in water indicates the presence of pathogenic bacteria. Let's understand this in detail:
What are B. coil and E. coil?
B. coil (Bacillus subtilis) and E. coil (Escherichia coli) are non-pathogenic bacteria that are commonly found in the environment, including water sources.
Why are they used as indicators of water quality?
B. coil and E. coil are used as indicators of water quality because their presence in water indicates the potential presence of pathogenic bacteria that may cause waterborne diseases. These non-pathogenic bacteria are easy to detect and are not harmful to humans, making them ideal indicators.
How do B. coil and E. coil indicate the presence of pathogenic bacteria?
Pathogenic bacteria are often present in water sources, but they are difficult to detect and identify. B. coil and E. coil, on the other hand, are easy to detect and are commonly used as indicators of water quality. If B. coil or E. coil are present in water, it indicates that the water has been contaminated with fecal matter, which can also contain pathogenic bacteria like Salmonella, Shigella, and Campylobacter. Therefore, the presence of B. coil or E. coil in water indicates that the water is potentially unsafe for human consumption.
Conclusion:
In conclusion, the presence of B. coil or E. coil in water indicates the potential presence of pathogenic bacteria that may cause waterborne diseases. Therefore, the presence of these non-pathogenic bacteria in water is a cause for concern and requires further testing to ensure that the water is safe for human consumption.
