Causes And Risk Factors For E. Coli Infection
Weakened Immune System

A weakened immune system will make it much easier for E. coli to cause havoc within the body. The immune system is the body's natural defense system against harmful viruses, bacteria, and other infected invaders. When it has been compromised or is failing to work properly, the body is more prone to infection and other illnesses. Having a weak immune system will not automatically result in an E. coli infection, but it can make you more susceptible to one. When E. coli comes in contact with the body, a healthy immune system will work to directly kill the bacteria and create antibodies, so the body recognizes the pathogen in the future.
