Which condition is caused by the bacterium Escherichia coli?

Escherichia coli, commonly known as E. coli, is a versatile bacterium that can inhabit the intestines of humans and animals. While it is most often associated with gastrointestinal infections, it is also a significant causative agent of urinary tract infections (UTIs). In fact, a specific strain known as uropathogenic Escherichia coli (UPEC) is responsible for the majority of uncomplicated urinary tract infections, particularly in females.

In UTIs, E. coli can ascend from the urethra to the bladder and potentially cause cystitis, leading to symptoms such as urgency, frequency, and painful urination. This ability to cause infections in the urinary tract is a well-documented aspect of E. coli's pathogenic profile.

While gastrointestinal distress, such as gastroenteritis, is also caused by certain strains of E. coli, the most prevalent and influential condition linked to E. coli in the context of this question is indeed urinary tract infections. Other conditions, such as pneumonia and strep throat, are associated with different bacteria and are not primarily linked to E. coli. Thus, identifying UTIs as a common outcome of E. coli infection highlights the bacterium's role in urological health issues.
