  #5

what about native vs damaged Valves?

  #6

I looked this up again n this is what i have

S. Viridians - MCC of IE overall (senn in 60% of Cases) & MC of Damaged Valves

S. Epidermis - MCC IE of Prostehtic Valves (If it is the causes it happens < 2 months after Prostehtic Valves have been placed, if > 2 months have pasted since the surgery than it is more likely to be S Viridians)

Staph - MCC if IE in IV Drug Abusers (Primarily Tric Valve) & also Rresponisble for seeding Normal Valves (in 20% of cases)

S Bovis - already mentioned (n don't forget to do Coonosc if Bovis is seen b/c of risk of Colon Cancer)
