Abstract

, the causative agent of septicemia anserum exsudativa (also called new duckling disease), belongs to the family of gram-negative bacteria. We determined the DNA sequences of the genes encoding the 16S rRNAs of four strains by directly sequencing PCR-amplified genes. A sequence similarity analysis confirmed the phylogenetic position of in the family in rRNA superfamily V and allowed fine mapping of on a separate rRNA branch comprising the most closely related species, , as well as , and . The sequences of the genes of the four strains varied between 0.5 and 1.0%, but all of the strains occupied the same position on the phylogenetic tree. In general, differences in genes were observed among strains, even within a given serotype, as shown by restriction fragment length polymorphism of PCR-amplified genes.
