Five strains of anaerobic thiaminolytic bacilli were isolated from the feces of patients suffering from various diseases without thiamine deficiency. These strains had the almost same morphological, biological and chemical properties as those of 3 standard strains of Clostridium thiaminolyticum Kimura et Liao, previously described. They had a little difference in the biological and chemical properties, compared with those of two strains of Clostridium sporogenes. On the contrary, at least 3 strains of these new isolates could be rather clearly distinguished from Clostridium sporogenes by the cross agglutination test using each of their heated antigens and rabbit antisera.
