Clostridium intestinalis sp. nov., an Aerotolerant Species Isolated from the Feces of Cattle and Pigs

Clostridium intestinalis sp. nov. is described on the basis of five strains isolated from the feces of cattle and pigs. The isolates are aerotolerant, gram-positive, sporeforming, motile rods. They differ from all the validly described aerotolerant species of the genus Clostridium by carbohydrate fermentation pattern, guanine-plus-cytosine content of the deoxyribonucleic acid, and deoxyribonucleic acid homologies. The fermentation products from peptone-yeast extract-Fildes solution-1 % (wt/vol) glucose broth are major amounts of acetic and butyric acids. The guanine-plus-cytosine content of the deoxyribonucleic acid is 26 to 28 mol%. The type strain of Clostridium intestinalis is Catt39 (= ATCC 49213 and JCM 7506).
