What is the organism most frequently isolated in splenic abscesses?
Streptococcal species are the most common bacterial isolates from splenic abscesses, followed by S. aureus—presumably reflecting the associated endocarditis.
Experimental work has helped to define both the host cells and the bacterial virulence factors responsible—most notably in the case of B. fragilis. This organism, although accounting for only 0.5% of the normal colonic flora, is the anaerobe most frequently isolated from intraabdominal infections, is especially prominent in abscesses, and is the most common anaerobic bloodstream isolate.
