The minimal inhititory concentration (MIC) of tilmicosin and oxytetracycline was dertermined forPasteurella haemolyticaisolated from Dutch cattle in 1991. The agar dilution method was used. Of thePasteurella haemolyticastrains examined, 96 (24) had a MIC for tilmicosin of 2 #x3BC;g/ml or lower; in one strain the MIC was 8 #x3BC;g/ml. The MIC for oxytetracycline was equal to or higher than 64 #x3BC;g/ml in 19 strains (76), whereas for 5 strains the MIC was 1 #x3BC;g/ml and for 1 strain 2 #x3BC;g/ml.
