Variation of the ribosomal operon 16S-23S gene spacer region in representatives of Salmonella enterica subspecies.

Journal of bacteriology - 1 Apr 1998

Abstract excerpt

The 16S-23S spacer regions of two ribosomal operons (rrnA and rrnE) have been sequenced in seven representatives of the Salmonella enterica subspecies. Isolated nucleotide substitutions were found at the same sites as in Escherichia coli but the number of polymorphic sites was much larger, as cou...
