Abstract

Three rhizosphere bacteria, Pseudomonas sp., Enterobacter sakazakii and Klebsiella oxytoca, were analyzed for genetic variation. DNA fingerprint patterns of the three bacteria were markedly different when amplified with different primers. In total, 68 bands were produced by the three primers, 62 of which where variable. The number of polymorphic RAPD loci per isolate ranged from one to 13. Cluster analysis indicated that E. sakazakii and K. oxytoca are the most closely related of the three.
