we conclude that systemic antibiotics are ineffective in the prevention of abscesses secondary to bacteria trapped in fibrin , either because they do not reach bactericidal levels in the fibrin clot , as in the case of gentamicin , ampicillin , and clindamycin , or , as in the case of cefoxitin , because of the inoculum effect caused by the high number of bacteria .
