What is the niche of ecoli?

Answer 1

Escherichia coli (E. coli) primarily occupies the intestinal tract of warm-blooded organisms, including humans, where it plays a crucial role in digestion and the synthesis of essential vitamins. While most strains are harmless and contribute to gut health, some pathogenic strains can cause foodborne illness and severe gastrointestinal issues. E. coli's adaptability allows it to thrive in various environments, including water and soil, making it a vital indicator organism for assessing water quality and sanitation. Its diverse roles in both health and disease exemplify its ecological niche within microbial communities.
