Surgical site infection after hip replacement due to a novel Peptoniphilus species, provisionally named 'Peptoniphilus nemausus' sp. nov.

We report a case of surgical site infection after total hip prosthesis replacement due to an ofloxacin-resistant Peptoniphilus isolate belonging to an unknown species for which the name 'Peptoniphilus nemausus' sp. nov. is proposed. Follow-up was favourable under clindamycin and rifampin for 3 months in this patient whom had a Proteus mirabilis infection treated by fluoroquinolone.
