title: [Bactericidal dosie-activity relationships with E. coli, K. pneumoniae and Staph. aureus (author's transl)].
abstract: In investigations into the dosis-activity relationships of bactericidal antibiotics used against E. coli, K. pneumoniae and Staph. aureus four types of activity could be demonstrated. The penicillin type shows almost no improvement in bactericidal activity despite increasing the dosage above a certain level. An increase in concentration of aminoglycoside antibiotics led to a more rapid killing of the bacteria. In cefalotin there was a linear dosis-activity relationship: rising concentrations of antibiotics led to an ever increasing bactericidal effect. The paradoxical bactericidal effect ("Eagle effect'') described for penicillin G with enterococci could not be demonstrated.
