title: Resistance ofBradyrhizobium japonicum strains to selected antibiotics.
abstract: The majority of the 50Bradyrhizobium japonicum strains tested were resistant to ampicillin, kanamycin, streptomycin and tetracycline in concentrations below 100 μg/ml but resistant to chloramphenicol in concentrations equal to or above 100 μg/ml. Two strains had high levels of resistance to ampicillin and to streptomycin and six strains were very sensitive to several antibiotics.
