Abstract Phlo.mo.bac.ter. Gr. n. phlomos bark; Gr. n. bakterion a small rod; M.L. neut. Phlomobacter rod in the bark. Filamentous bacteria occurring in the sieve tubes of phloem tissue of plants (Figures 1 and 2). The original description is from infected strawberry plants ( Fragaria × ananassa ) showing leaf marginal chlorosis and stunting in France (Nourrisseau et al., 1993). Like most other phloem‐restricted bacteria, Candidatus Phlomobacter fragariae has resisted in vitro cultivation. The mol % G + C of the DNA is : not determined. Type species : Candidatus Phlomobacter fragariae Zreik, Bové and Garnier 1998, 260.

Abstract Xi.phi.ne.ma.to.bac'ter. Gr. neut. n. Xiphinema, ‐atos the genus name of the host organism; N.L. masc. n. bacter the equivalent of Gr. neut. n. baktron a rod; N.L. masc. n. Xiphinematobacter the rod‐shaped microbe associated with Xiphinema . Full‐grown cells are rod‐shaped with rounded ends, 0.7–1.0 × 2.1–3.2 μm ; however, cells in the J 1 (first juvenile) stage of nematode development have a wrinkled, pleomorphic shape. The longer entities usually consist of a mother cell from which a daughter cell is budding, giving rise to serial pairs typical of this bacterial genus. In thin sections cells have two or three membranes consisting of, from inside to outside, a cytoplasmic membrane, an electron‐dense outer membrane, and, in many individuals, a vacuolar membrane which is probably derived from the host cell membrane and which often shows discontinuities. No peptidoglycan layer is evident ; however, a periplasmic hexagonally arrayed monolayer of 10 nm protein units is sometimes present. Gram‐stain‐negative, nonmotile, and nonsporulating. DNA is often condensed at cell poles . Bacteria live as obligate cytoplasmic symbionts with maternal transmission in nematodes of the Xiphinema americanum group ( Nematoda, Longidoridae ), in which they are presumed to induce thelytokous ( mother‐to‐daughter ) parthenogenesis . DNA G + C content ( mol %): not determined. Type species : “ Candidatus Xiphinematobacter brevicolli ” Vandekerckhove, Willems, Gillis and Coomans 2000, 2203.

Abstract Cla.vi.chla.my'di.a. L. n. clava a knotty branch, rough stick, cudgel, club; N.L. fem. n. Chlamydia taxonomic name of a bacterial genus; N.L. fem. n. Clavichlamydia a club Chlamydia (the morphology of the bacteria includes the characteristic head‐and‐tail cells that have been described earlier from salmonid fish suffering from epitheliocystis). Pleomorphic or elongated , nonmotile , obligate intracellular bacteria , up to 2 μ m in length . Cells show a developmental cycle with morphologically distinct stages and thrive inside a host vacuole . Organisms were found within gill lesions of fish and are differentiated from all other chlamydiae by the morphology of the proposed elementary bodies , which show a characteristic head‐and‐tail form (Figure 1). Members have not yet been obtained in cell culture. Type species : “ Candidatus Clavichlamydia salmonicola ” corrig. Karlsen, Nylund, Watanabe, Helvik, Nylund and Plarre 2008.

LPSN classification: Bacteria / Pseudomonadati / Chlamydiota / Chlamydiia / Chlamydiales / Chlamydiaceae / Candidatus Clavichlamydia The genus Candidatus Clavichlamydia can also be recovered in the Genome Taxonomy Database (GTDB) as g__Clavichlamydia (version v220) ** .
