In IV drug abusers probability of endocarditis is with descending order
Staph aureus = 50%
Sterpto coccus A = 15%
Gm -tive = 15% (among them pseudomonas is the most common)
Candida = 10%
So in the above mentioned organism Candida is the only candidate to be causitive organism of Endocarditis.
Secondly Candida is among the normal flora of skin but none of the other mentioned organisms.
Best of luck
