| Abstract: | Summary The minimal inhititory concentration (MIC) of tilmicosin and oxytetracycline was dertermined for Pasteurella haemolytica isolated from Dutch cattle in 1991. The agar dilution method was used. Of the Pasteurella haemolytica strains examined, 96% (24) had a MIC for tilmicosin of 2 μg/ml or lower; in one strain the MIC was 8 μg/ml. The MIC for oxytetracycline was equal to or higher than 64 μg/ml in 19 strains (76%), whereas for 5 strains the MIC was 1 μg/ml and for 1 strain 2 μg/ml. |
