Abstract
The venous blood samples were cultured to determine the incidence of transient bacteremia immediately after tooth extraction. Cultured positive rates were 27 (69.2%) out of 39 tested cases. The isolated organisms were 47 strains, while oral streptococci occupied 18. Anaerobic organisms such as genus Gemella and genus Peptostreptococci included, 35 (74.4%) out of 47 isolated strains belonged to streptococci group MICs were tested on 7 antimicrobial agents; ampicillin, penicillin V, cefteram (cefteram pivoxil is the substance), cefpodoxime (cefpodoxime proxetil is the substance), erythromycin, ofloxacin and tosufloxacin. The susceptibilities of ampicillin and cefteram were excellent. Considering the high figure incidence (69.2 %) of transient bacteremia after tooth extraction, we should apply chemopro-phylaxis to a wider range of other patients other than those who have heart disease.
