🧍 However, Rhodospirillum centenum Favinger et al. 1994 and Rhodocista centenaria Kawasaki et al. 1994 are homotypic synonyms and neither is the earlier (senior) synonym [3]. So, the name which is to be used is this which is correct in the opinion of a bacteriologist.Publication:

🧍 In the ASM News [1] and in a Letter to the Editor of the IJSEM [2], Gest and Favinger have presented a list of objections to using the name Rhodocista centenaria Kawasaki et al. 1994. However, Rhodospirillum centenum Favinger et al. 1994 and Rhodocista centenaria Kawasaki et al. 1994 are homotypic synonyms and neither is the earlier (senior) synonym [3]. So, the name which is to be used is this which is correct in the opinion of a bacteriologist.Publication:

🧍 Rhodocista centenaria and Rhodospirillum centenum have been validly published by announcement in Validation List no. 48. These two names have the same type strain (ATCC 43720) and the same priority number (priority number 2). Therefore they are homotypic synonyms and no priority can be established. So, Rhodocista centenaria is a new species not a new combination as cited in the Validation List no. 48 and the correct citation of this name is Rhodocista centenaria Kawasaki et al. 1994, sp. nov.Publication:
