Abstract

The biological and biochemical properties, DNA base compositions, and levels of DNA-DNA homology of two biovars of were examined. Some differences were found between the two biovars in biological and biochemical properties. The G+C contents of DNAs from biovar A strains VPI 2891 (T = type strain), NCTC 10576, N167, Fn47, and Fn43, were 32, 30, 29, 28, and 31 mol%, respectively. The G+C contents of DNAs from biovar B strains Fn524, 606, Fn49, Fn45, and 1260 were 30, 31, 27, 31, and 30 mol%, respectively. Labeled DNA from biovar A strain VPI 2891 exhibited 100 to 80% relatedness to DNAs from biovar A strains and 59 to 51% relatedness to DNAs from biovar B strains. Labeled DNA from biovar B strain Fn524 exhibited 100 to 81% relatedness to DNAs from biovar B strains and 71 to 60% relatedness to DNAs from biovar A strains. Therefore, the names subsp. subsp. nov., nom. rev. (ex Flügge 1886), and subsp. subsp. nov., nom. rev. (ex HallÉ 1898), are proposed for biovars A and B, respectively. The type strain of subsp. is strain VPI 2891 (= JCM 3718 = ATCC 25286), and the type strain of subsp. funduliforme is strain Fn524 (= JCM 3724).
