[Antibacterial activity, place of action and mechanism of resistance of pulmonal effecting antibiotics (author's transl)].

Antibiotics are of high importance in iatrogenic pathology. The emergence of resistent strains is a sanitary problem of remarkable consequences particularly under hospital conditions. Modern pulmology is not imaginable without antibiotic and chemotherapeutic drugs. A rational and economic therapy is possible only if the mechanisms and sites of antibacterial action and of drug resistance in bacteria are known.
