Polynucleotide sequence divergence among strains of Salmonella sub-genus IV and closely related organisms.
Polynucleotide sequence relatedness studies were carried out to determine the extent of divergence present in Salmonella sub-genus IV strains, related strains of Salmonella of other sub-genera and the Citrobacter genus. Salmonella sub-genus IV were 91-97% related. The Salmonella of sub-genus I, II and III showed lower binding (79-87%) to Salmonella sub-genus IV. The change in thermal elution midpoint closely followed the reassociation data. Relatedness of Salmonella sub-genus IV and C. freundii ranged between 44 and 57%, which confirms that these organisms belong to different genera. The taxonomic position of Salmonella sub-genus IV is discussed according to the actual classification of the family Enterobacteriaceae.
