“…Reproducibly, all strains showed respiration on L-alanine, L-glutamic acid, methyl pyruvate, L-malic acid, bromosuccinic acid, Tween 40 and acetic acid. Utilization of these compounds in liquid mineral medium was confirmed following established protocols (Nemec et al, 2009). …”

“…The metabolic capabilities of the five strains were further tested following protocols established for Acinetobacter (Nemec et al, 2009), and were compared to the data recently provided for all species of the genus with validly published names (Krizova et al, 2015). Table 1 summarizes the phenotypes of the proposed novel species and of the three most similar species according to Biolog analyses, the most closely related species according to core genome-based phylogeny (A. bouvetii), as well as the species with less than six differentiating traits (Krizova et al, 2015).…”

“…After centrifugation of the samples, 2 ml supernatant was taken as a template to test by PCR for the bla OXA-51-like carbapenemase gene intrinsic to A. baumannii (Turton et al, 2006). As the result was negative, partial sequencing of the rpoB gene from strain 114 T was conducted using primers Ac696F and Ac1598R as described previously (Nemec et al, 2009). The resulting sequence of 861 bp (GenBank accession no.…”

The taxonomic position of five strains isolated from horse faeces, and which shared identical 16S rRNA gene sequences, were studied. Cells of all isolates are Gram-stain-negative, obligately aerobic and have a rod-shaped appearance. The strains show highest 16S rRNA gene sequence similarities to Acinetobacter lwoffii (98.3 %), Acinetobacter haemolyticus (98.0 %), Acienetobacter johnsonii (97.9 %) and Acinetobacter brisouii (97.9 %). Whole-genome sequencing of strain 114 T and phylogeny reconstruction based on a core set of 1061 Acinetobacter genes indicated that A. bouvetii CIP 107468 T was the closest relative among species of the genus Acinetobacter for which whole genome sequences are available. The genomic DNA G+C content of strain 114 T is 34.9 mol%, which is lower than any other value reported for the genus Acinetobacter. The predominant polyamine is 1,3-diaminopropane, which is typical for the genus Acinetobacter. The most abundant fatty acids are C 16 : 1 v7c and/or iso-C 15 : 0 2-OH (36 %) and C 16 : 0 (28 %). The proportion of C 18 : 1 v9c (7 %) is distinctively low compared to most species of the genus. The major ubiquinone of strain 114 T is Q-9. Microscopic studies revealed the presence of pili and the absence of flagella. The capability of all five strains to utilize L-arabinose and gentisate as well as their lack of growth at temperatures of 41 8C and above provide sufficient criteria to distinguish the isolates from all species of the genus Acinetobacter with validly published names. Based on these combined data, the five isolates represent a novel species of the genus Acinetobacter, for which the name Acinetobacter equi sp. nov. is proposed. The type strain is 114 T (5DSM 27228 T 5CCUG 65204 T ).

Two Gram-negative, non-motile, rod-shaped strains, BQ4-1 T and NHI3-2, isolated respectively from the healthy and diseased part of Populus ¾euramericana canker bark, were characterized using a polyphasic approach. Chemotaxonomic characterization supported the inclusion of the two strains in the genus Acinetobacter, with genomic DNA G+C contents (42.5-43 mol%) within the range observed for this genus (38-47 mol%) and 9-octadecenoic acid (C 18 : 1 v9c, 39.87 %), hexadecanoic acid (C 16 : 0 , 11.26 %) and summed feature 3 (comprising C 16 : 1 v7c/ C 16 : 1 v6c, 18.90 %) as major fatty acids. Phylogenetic analysis based on 16S rRNA, rpoB and gyrB gene sequences revealed that strains BQ4-1 T and NHI3 did not cluster with any species with validly published names, and formed a distinct cluster with 99-100 % bootstrap support on three phylogenetic trees within the genus Acinetobacter. Acid was not produced from D-glucose, and haemolysis was not observed on agar media supplemented with sheep erythrocytes. On the basis of phenotypic, genotypic and phylogenetic characteristics, the two strains are considered to represent a novel species of the genus Acinetobacter, for which the name Acinetobacter puyangensis sp. nov. is proposed. The type strain is BQ4-1 T (5CFCC 10780 T 5JCM 18011 T ).

A.ci.ne.to.bac'ter. Gr. masc. adj. akinetos unable to move; N.L. masc. adj. bacter , a rod; N.L. masc. n. Acinetobacter , a non‐motile rod. Proteobacteria / Gammaproteobacteria / Pseudomonadales / Moraxellaceae / Acinetobacter Rods 0.9–1.6 × 1.5–2.5 μm, becoming spherical in the stationary phase of growth. Colonies are generally nonpigmented and are mucoid when the cells are encapsulated. Cells commonly occur in pairs. Do not form spores. Gram‐stain‐negative. Flagella are absent, and swimming motility does not occur, but cells display twitching motility associated with fimbriae. Strictly aerobic. Oxidase‐negative. Catalase‐positive. Mesophilic. Most strains do not reduce nitrate to nitrite in conventional assays. Grow well on complex media. Most strains grow in defined media containing a single carbon and energy source (most commonly acetate), using ammonium or nitrate salts or one of several common amino acids, as a source of nitrogen. The genome consists of a single circular chromosome sized 2.6−4.7 Mb and a strain‐dependent set of plasmid replicons. Widespread in nature, inhabiting diverse soil and water ecosystems and being associated with plants and animals. Some species reside on the human skin and mucosa. Several species can cause nosocomial infections; strains involved are often resistant to multiple antibiotics and can give rise to epidemics. In 2021, the genus included 73 species with correct names. DNA G + C content (mol%) : 34.9−49.6 (median: 40.2). Type species : Acinetobacter calcoaceticus Baumann et al. 1968b AL (basonym: Micrococcus calcoaceticus Beijerinck 1911) emend. Bouvet and Grimont 1986.
