What are the dangers of bacterial infections?
An untreated bacterial infection can also put you at risk for developing a life-threatening condition called sepsis. Sepsis occurs when an infection causes an extreme reaction in your body. The bacteria most likely to cause sepsis include Staphylococcus aureus, E. coli, and some types of Streptococcus.
