[Studies on the excretion of various aminoglycosides in rat milk (author's transl)].

10 mg/kg of strepto-, neo-, kanamycin, genta- and sisomicin were applied s.c. to rats in lactation. After 0.5, 1, 2, 4, 6, 8 and 24 h the animals were milked. The antibacterial concentrations in the milk were determined in comparison to the serum concentrations. Strepto-, neo- and kanamycin showed the highest concentrations in the serum, genta- and sisomicin the highest in the milk.
