| Abstract | ||||
| Ten effective Isolates of R. legumiserum biovar phaseo/i (phaseoiqs vulgaris L.) were isolated from 3 governorales of lower Egypt (Katr EI·Sheikh, EI 8ehera and EI Gharbia ) at different locations during season (2002). AUlhe tesled isolates gave positive results when su~Jected to purify tests. Screenin~ of the Isolates, using intrinsic anUbiotk. resistance (II\P.) melhod against ampiCillin, kanamycin sulphate, rifampicin, streptomycin sulphate, neomycin, dexacillln, erythromycin, terramycin, topramycin and colistin sulphate at 10 and high concentration and showed variability to other antibiotics tested. On the basis of serological analysis, the representative isolates of IAR groups are classified into four groups. Comparing IAR identificalion patterns of the isolates, with serotyplng data. It was found that many lsoletes which showed similar pattern to antibiotic resistance could be considered as one serotype. The representative strains were investigated for their symbiotic p rformance under controUed conditions. Results showed that the obtained strains exerted different responses in association with its specific host of p < /em>haseo/us vi/garis var. Gil . | ||||
