Numerical Taxonomy of Listeria, Streptococci and Possibly Related Bacteria

SUMMARY: Similarity values based on 199 features of 88 strains of bacteria, including freshly-isolated strains of streptococci and named strains of the genera Streptococcus, Listeria, Microbacterium, Erysipelothrix, Brevibacterium and Arthrobacter, were analysed by single and complete linkage sorting programmes. It is concluded that Erysipelothrix, Listeria and strains currently known as Microbacterium thermosphactum show closer relations to the family Lactobacillaceae than to the other representatives of the family Coryne-bacteriaceae here examined.
