Can any bacterial infection become septic?

Sepsis: Most bacterial infections do not spread into the blood stream, the definition of sepsis. Most simple infection, such as skin infections, or bladder infections do not spread. But lung infections (pneumonia), kidney infections (pyelonephritis), deep skin abcesses, gall bladder infections, appendicitis, all can spread bacterial to the blood stream. Sepsis can be deadly, and needs hospitalization.

You bet: The term sepsis is defined as two or more of fever, elevated or low WBC counts, rapid heart rate, rapid respirations secondary to infection. This can occur with any bacterial infection. If you are using the term to suggest bacteria in the blood a better word would be bacteremia, and this too can occur in any infection.
