We propose a new species, Flavobacterium thalpophilum. Each of the seven strains placed in this new species was examined for 129 characteristics, including 58 enzyme reactions (API ZYM System). These bacteria are rodshaped, aerobic, gram negative, and nonmotile and oxidize glucose in oxidation-fermentation medium. The mean guanine-plus-cytosine content of the deoxyribonucleic acids of seven strains is 45.0 ± 0.8 mol%. The distinguishing features of the new species include an ability to reduce nitrate, an ability to grow at 42°C, and an ability to produce acid from various carbohydrates and alcohols. In particular, the ability of F. thalpophilum strains to produce acid from adonitol distinguishes them from all other Flavobacterium species. The seven strains of the new species were isolated from human clinical specimens. The type strain is strain K-1173 (= NCTC 11429).
