“CDC棒形1群”细菌最初在1985年报道。1994年本文作者研究了该菌群的确切分类地位,表明是放线菌属的一个新种,命名为纽氏放线菌(Actinomyces neuii)。它含有2个亚种:纽氏亚种(subsp.neuii)和无硝亚种(subsp.anitratus)。亚种之间的表型反应很易区别。作者在1990年4月～1994年9月的4年半中,研究了纽氏放线菌感染的67例病人,发现该菌最常在脓肿和粉瘤感染中被检测到。67例中有30例为脓肿患者(主要 The “CDC Rod 1” bacteria were first reported in 1985. In 1994, the authors studied the exact taxonomic status of this flora, indicating that it is a new species of actinomycetes, named Actinomyces neuii. It contains two subspecies: subsp. Neuii and subsp. Anitratus. Phenotypic responses between subspecies are easy to distinguish. In four and a half years between April 1990 and September 1994, the authors studied 67 patients with Actinobacterium neoformans infection and found that the bacteria were most commonly detected in abscesses and atheroma. Thirty of 67 cases were abscess patients (mainly
