Yes, Escherichia coli (E. coli) can indeed act as an opportunistic pathogen. This means that while it normally resides harmlessly in the intestines of humans and animals, under certain conditions, it can cause infections, especially when the host’s immune system is compromised or when it gains access to other parts of the body where it doesn’t belong. Factors such as antibiotic use, underlying medical conditions, and weakened immune defenses can increase the risk of E. coli infections becoming problematic.
