the isolates were also very susceptible to rosaramicin ( minimal concentration at which 50 % of isolates were inhibited [ mic50 ] = 0.02 micrograms/ml ) and to the new cephalosporins ( cefotaxime mic50 less than 0.007 micrograms/ml , ceftriaxone mic50 less than 0.007 micrograms/ml , and ceftazidime mic50 less than 0.007 micrograms/ml ) .
