Özet

© 2021 Elsevier GmbHIn a study carried out between 2013 and 2018 in fish farms in Turkey, several putative novel species were isolated. The 16S rRNA nucleotide sequences of fourteen strains of Gram-negative rods, which were isolated from asymptomatic and symptomatic rainbow trouts (Onchorhynchus mykiss), placed them under the genus Pseudomonas. The similarity values of the concatenated nucleotide sequences of the rpoD, rpoB, gyrB and 16S rRNA genes clustered these isolates into the P. fluorescens phylogenetic group of species and into the Pseudomonas koreensis subgroup, close to Pseudomonas helmanticensis and Pseudomonas baetica. An isolate of a totally different origin, strain CCUG 67011, clustered with these isolates. Phenotypic characterization, together with the chemotaxonomic data, whole-cell MALDI-TOF MS and fatty acids methyl esters analyses were performed. The DNA G + C content was 58.7 mol% for isolate P9T and 58.8 mol% for isolate P42T. The phylogenomic analysis and whole genome nucleotide sequences of four of these isolates confirmed that the isolates P9T, P25 and P141, represent a novel species for which the name Pseudomonas anatoliensis sp. nov. is proposed, with P9T as the type strain (=CCUG 74755T = CECT 3172T). The isolates P1, P2, P10, P27, P30, P24a, P42T, P117, P139, P152 and CCUG 67011 represent another novel sècies, for which the name Pseudomonas iridis sp. nov. is proposed, with P42T as the type strain (=CCUG 74870T = CECT 3174T).
