acute prostatitis is relatively easy to diagnose due to its symptoms that suggest infection. common bacteria are "e. coli, klebsiella, proteus, pseudomonas, enterobacter, enterococcus, serratia," and "staphylococcus aureus." this can be a medical emergency in some patients and hospitalization with intravenous antibiotics may be required. a full blood count reveals increased white blood cells. sepsis from prostatitis is very rare, but may occur in immunocompromised patients; high fever and malaise generally prompt blood cultures, which are often positive in sepsis.
