Prosthecobacter fusiformis gen. and sp. nov., nom. rev.

The names Prosthecobacter Staley et al. and Prosthecobacter fusiformis Staley et al., were not included in the recently published Approved Lists of Bacterial Names and hence have no standing in bacteriological nomenclature. However, these names are here revived for the same organisms with which they were originally associated and, by this action, now have valid status.
