Abstract: | Summary Identification ofRhizobium trifolii strains using intrinsic antibiotic resistance and serology was performed. Unknown strains, generated by mixing known strains
in a common broth, always reacted with only one antiserum but showed variable intrinsic antibiotic resistance patterns. All
unknowns were rapidly and unambiguously identified by the immunological double diffusion technique, while 33% of the unknowns
were either unidentifiable or identified incorrectly when resistance to various antibiotics was measured. It is concluded
that serology is less variable than instrinsic antibiotic resistance when strains ofR. trifolii are identified. |
