Phylogenetics of Salmonella enteritidis.
The phylogenetics of Salmonella enteritidis is reviewed. Data from RFLP typing with cloned chromosomal DNA, rRNA genes and insertion sequence probes are described. Human isolates of this serovar exhibit a high degree of genotypic homogeneity. Multilocus enzyme electrophoresis defines S. enteritidis as a polyphyletic serovar closely related to S. dublin, S. gallinarum and S. pullorum. Two main classes of virulence plasmids are found in S. enteritidis. We report a comparative study of genotype for three principal clones of S. enteritidis, six other serovars carrying the g flagellar antigen, and S. pullorum. It is suggested that S. enteritidis occupies an ancestral and pivotal position among these Salmonellae.
