I will go also for E) G(+) cocci

INFECTIVE ENDORCADITIS

IE may be acute or subacute; org assoc with:

- Acute IE are generally more virulent (m.c. S. aureus) and are capable of infecting previous normal or abnormal valves.

- Subacute IE are usually less virulent (m.c. S. viridans) and infect previous damaged valves

Overall S. viridans is the m.c. pathogen causing IE followed by S. aureus.

In pts with prosthetic heart valves, Coagulase negative Staphylococci are m.c.

In IV drug abusers S. Aureus is the m.c.org isolated in the blood.

Mitral valve most common involved. However in IV drug abusers the Tricuspide and aortic valves are equally affected. predisposing to embolization (strokes, splenic infarcts)

Straight out of First Aid:

"Complications of Bacterial Endocarditis include Chordae Rupture, GN, Emboli, and SUPPURATIVE PERICARDITIS"

Hope this helps! =)

Dental work typically causes SBE via Streptococcus viridans group, of which there are many subspecies.
