<i>Listeria tempestatis</i> sp. nov. and <i>Listeria rocourtiae</i> subsp. <i>hofi</i> subsp. nov.

ABSTRACT: In September 2018, Hurricane Florence resulted in major flooding in North Carolina, USA. Efforts to isolate Listeria monocytogenes and other Listeria spp. from Hurricane Florence floodwaters repeatedly yielded non-haemolytic Listeria-like isolates that could not be readily assigned to known Listeria taxa. Whole-genome sequence analyses against the 28 currently known Listeria species confirmed that the isolates constitute two new taxa within the genus Listeria. Taxon I, with one isolate, showed the highest similarity to Listeria goaensis, with an average nucleotide identity blast of 85.3±4.4% and an in silico DNA-DNA hybridization (isDDH) of 32.4% (range: 30-35%), differing from the latter by its ability to reduce nitrate, ferme
