Jeotgalibaca ciconiae sp. nov., isolated from the faeces of an Oriental stork

Jeotgalibaca caeni sp. nov., isolated from biochemical tank sludge

A Gram-stain-positive, coccoid-shaped, non-spore-forming, facultatively anaerobic bacterium, designated YN-L-12T, was isolated from the activate sludge of a pesticide plant. Colonies on tryptone soya agar were small, white, opaque and circular. Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain YN-L-12T belonged to the genus of Jeotgalibaca, and showed the highest similarity to Jeotgalibaca arthritidis 1805-02T (97.0 %), followed by Jeotgalibaca ciconiae H21T32T (96.5 %), Jeotgalibaca porci 1804-02T (95.6 %) and Jeotgalibaca dankookensis EX-07T (95.4 %). The strain grew at 15-37 °C (optimum, 30 °C), with 0-6.5 % (w/v) NaCl (optimum, 0.5 %) and at pH 7-9 (optimum, pH 7.5). The major fatty acids were C18 : 1 ω9c, C16 : 1 ω9c and C16 : 0. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, glycolipid and an unidentified lipid. The DNA G+C content of the strain was 41.1 mol%. Average nucleotide identity values between strain YN-L-12T and J. arthritidis 1805-02T and J. ciconiae H21T32T were 72.8 and 72.3 %, respectively. The digital DNA-DNA hybridization values between YN-L-12T and J. arthritidis 1805-02T and J. ciconiae H21T32T were 24.1 and 20.3 %, respectively. According to the results of phenotypic, chemotaxonomic and phylogenetic analyses, strain YN-L-12T represents a novel species of the genus Jeotgalibaca, for which the name Jeotgalibaca caeni sp. nov. is proposed, with strain YN-L-12T (=KCTC 43533T=CCTCC AB 2022400T) as the type strain.

Update on Novel Taxa and Revised Taxonomic Status of Bacteria Isolated from Nondomestic Animals Described in 2018 to 2021

Revisions and new additions to bacterial taxonomy can have a significant widespread impact on clinical practice, infectious disease epidemiology, veterinary microbiology laboratory operations, and wildlife conservation efforts. The expansion of genome sequencing technologies has revolutionized our knowledge of the microbiota of humans, animals, and insects. Here, we address novel taxonomy and nomenclature revisions of veterinary significance that impact bacteria isolated from nondomestic wildlife, with emphasis being placed on bacteria that are associated with disease in their hosts or were isolated from host animal species that are culturally significant, are a target of conservation efforts, or serve as reservoirs for human pathogens.

Description of Ornithinimicrobium ciconiae sp. nov., and Ornithinimicrobium avium sp. nov., isolated from the faeces of the endangered and near-threatened birds

Phenotypic and genomic analyses were performed to characterize two novel species, H23M54^T and AMA3305^T, isolated from the faeces of the Oriental stork (Ciconia boyciana) and the cinereous vulture (Aegypius monachus), respectively. Strains H23M54^T and AMA3305^T showed the highest similarities of 16S rRNA gene sequences and complete genome sequences with Ornithinimicrobium cavernae CFH 30183^T (98.5% of 16S rRNA gene sequence similarity and 82.1% of average nucleotide identity, ANI) and O. pekingense DSM 21552^T (98.5% of 16S rRNA gene sequence similarity and 82.3% of ANI), respectively. Both strains were Gram-stain-positive, obligate aerobes, non-motile, non-spore-forming, and coccoid- and rodshaped. Strain H23M54^T grew optimally at 25-30°C and pH 8.0 and in the presence of 1.5-2% (wt/vol) NaCl, while strain AMA3305^T grew optimally at 30°C and pH 7.0 and in the presence of 1-3% (wt/vol) NaCl. Both strains had iso-C_15:0, iso-C_16:0, and summed feature 9 (iso-C_17:1ω9c and/or C_16:0 10-methyl) as major cellular fatty acids. MK-8 (H₄) was identified as the primary respiratory quinone in both strains. Strains H23M54^T and AMA3305^T possessed diphosphatidylglycerol and phosphatidylglycerol as major polar lipids. Moreover, strains H23M54^T and AMA3305^T commonly contained ribose and glucose as major sugars and L-ornithine, L-alanine, glycine, and aspartic acid as major amino acids. The polyphasic taxonomic data indicate that strains H23M54^T and AMA3305^T represent novel species of the genus Ornithinimicrobium. We propose the names Ornithinimicrobium ciconiae sp. nov. and Ornithinimicrobium avium sp. nov. for strains H23M54^T (= KCTC 49151^T = JCM 33221^T) and AMA3305^T (= KCTC 49180^T = JCM 32873^T), respectively.
