Primary actinomycotic endocarditis is extremely rare. The author reported a case who suffered from
endocarditis due to Actinomyces georgiae which the portal of entry for the organism could not be determined.
The author also reviewed the literature which described similar conditions. In addition, to the author’s
knowledge, there have been no reported cases of actinomyces georgiae endocarditis. Thus, this is the first
report in the world. Clinical features of this rare condition are indistinguishable from other bacterial
endocarditis. Actinomyces spp. is usually susceptible to a wide range of antibiotics, and endocarditis caused
by this genus needs a prolonged course of antimicrobial treatment. However, the optimal duration of therapy
is still unknown. Prognosis is good with early detection and proper management.
