在对来自4周龄肉鸡盲肠内容物的丁酸盐产生微生物群的研究过程中获得了产生大量丁酸盐的五个分离株。这五个分离株在生化和遗传方面几乎没有区别，这表明它们来自于一个单一的细菌克隆殖民这个栖息地。基于16 S rRNA基因序列的系统发育分析表明，5个分离株代表梭菌属的纤细梭菌亚组内的独特谱系，其中Desmolans真杆菌是最接近的系统发育邻居（约93%相似性）。这些数据表明，这五个新分离株代表了一个新属中的一个新种，我们建议将其命名为Butyricicoccus pullicaecorum gen. nov.，模式菌株为25-3（T）（=LMG 24109（T）=CCUG 55265（T））。菌株25- 3 T的DNA G + C含量为54.5mol%。
Five isolates that produced large amounts of butyrate were obtained in the course of a study on the butyrate-producing microbiota from the caecal content of a 4-week-old broiler chicken. The five isolates were virtually indistinguishable in biochemical and genetic terms, suggesting that they were derived from a single bacterial clone colonizing this habitat. A phylogenetic analysis based on 16S rRNA gene sequences demonstrated that the five isolates represented a unique lineage within the Clostridium leptum subgroup of the clostridia, with Eubacterium desmolans as the closest phylogenetic; neighbour (about 93 % similarity). These data indicate that the five novel isolates represent a single novel species within a novel genus, for which we propose the name Butyricicoccus pullicaecorum gen. nov., sp. nov. The type strain of Butyricicoccus pullicaecorum is 25-3(T) (=LMG 24109(T) =CCUG 55265(T)). The DNA G + C content of strain 25-3T was 54.5 mol%.
