title: Presence of antibacterial agents in blood units collected from healthy voluntary donors.
abstract: 10,991 sera collected from voluntary blood donors were tested during a 1-year period (1979) for the presence of antibacterial drugs. Antibacterial activity was found in 0.25% of them, and could be related to beta-lactam antibiotics and to cotrimoxazole. The implications of these findings are discussed.
