Abstract
Members of the genus Erysipelothrix are emergent pathogens of cultured eels, as well as several characid and cyprinid species. Since 2013, E. rhusiopathiae has been reported from diseased barramundi (Lates calcarifer) cultured in North America; we recovered 8 E. rhusiopathiae isolates from diseased fish during different outbreaks from the same farm. The E. rhusiopathiae isolates from barramundi were compared phenotypically and genetically to E. piscisicarius isolates characterized from ornamental fish and E. rhusiopathiae recovered from aquatic and terrestrial animals. All barramundi isolates were PCR-positive for the surface protective antigen type B (spaB) gene, and shared ≥ 99.7% sequence similarity among concatenated multilocus sequence analysis gene sequences, indicating a high degree of genetic homogeneity. These isolates were > 99% similar to other spaB-positive isolates from marine invertebrates and marine mammals, consistent with findings for other spa types. The spaA and spaB isolates shared < 98% similarity, as well as < 90% similarity with spaC-positive E. piscisicarius. Similar clonality among the spaB isolates was observed using repetitive element palindromic PCR. In experimental intracoelomic injection challenges conducted to fulfill Koch postulates, 67% of exposed tiger barbs (Puntigrus tetrazona) died within 14 d of challenge. Our study supports previous work citing the genetic variability of Erysipelothrix spp. spa types and the emergence of members of the genus Erysipelothrix as nascent fish pathogens.

Abstract
Seven genotypically distinct strains assigned to the genus
Erysipelothrix
were isolated in different laboratories from several animal sources. Strain D17_0559-3-2-1T and three further strains were isolated from samples of duck, pig and goose. The strains had >99 % 16S rRNA gene sequence similarity to each other and to strain VA92-K48T and two further strains isolated from samples of medical leech and a turtle. The closest related type strains to the seven strains were those of
Erysipelothrix inopinata
(96.74 %) and
Erysipelothrix rhusiopathiae
(95.93 %). Average nucleotide identity, amino acid identity and in silico DNA–DNA hybridization results showed that the strains represented two separate novel species. One further phylogenetically distinct strain (165301687T) was isolated from fox urine. The strain had highest 16S rRNA gene sequence similarity to the type strains of
Erysipelothrix tonsillarum
(95.67 %), followed by
Erysipelothrix piscisicarius
(95.58 %) and
Erysipelothrix larvae
(94.22 %) and represented a further novel species. Chemotaxonomic and physiological data of the novel strains were assessed, but failed to unequivocally differentiate the novel species from existing members of the genus. MALDI-TOF MS data proved the discrimination of at least strain 165301687T from all currently described species. Based on the presented phylogenomic and physiological data, we propose three novel species, Erysipelothrix anatis sp. nov. with strain D17_0559-3-2-1T (=DSM 111258T= CIP 111884T=CCM 9044T) as type strain, Erysipelothrix aquatica sp. nov. with strain VA92-K48T (=DSM 106012T=LMG 30351T=CIP 111492T) as type strain and Erysipelothrix urinaevulpis sp. nov. with strain 165301687T (=DSM 106013T= LMG 30352T= CIP 111494T) as type strain.
