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. Taxonomic and Nomenclature Notes According to the List of Prokaryotic names with Standing in Nomenclature (LPSN), the taxonomic status of the genus Candidatus Xiphinematobacter is: preferred name (not correct name) (last update, February 2025) * .

Abstract A.my.co.la.top'sis. N.L. fem. n. Amycolata genus belonging to the order Actinomycetales ; Gr. fem. n. opsis aspect, appearance; N.L. fem. n. Amycolatopsis that which appears similar to Amycolata . Aerobic to facultatively anaerobic , Gram‐stain‐positive , non‐acid‐fast , nonmotile , catalase‐positive actinomycetes that form branching substrate hyphae which fragment into squarish and rod‐shaped elements . When formed , aerial hyphae may be sterile or differentiate into chains of smooth‐walled , squarish to ellipsoidal spore‐like structures . Chemo‐organotrophic to facultatively autotrophic. Grows on a broad range of organic and synthetic media. Mesophilic or thermophilic. Whole‐organism hydrolysates are rich in meso ‐2 , 6‐diaminopimelic acid , arabinose , and galactose . The peptidoglycan is of the A1γ type. Muramic acid moieties are N ‐acetylated. The diagnostic phospholipid is phosphatidylethanolamine ( with or without phosphatidylmethylethanolamine ) or phosphatidylmethylethanolamine with variable occurrence of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol, and phosphatidylinositol mannosides; contains complex mixtures of saturated and branched chain fatty acids . Does not contain mycolic acids. The phylogenetic position of Amycolatopsis , as determined by 16S rRNA gene sequence analysis, is in the family Pseudonocardiaceae . Common in arid soils but has also been isolated from activated sludge, equine placentas, and from clinical and plant material. DNA G + C content ( mol %): 66–75 ( T m ; HPLC). Type species : Amycolatopsis orientalis (Pittenger and Brigham 1956) Lechevalier, Prauser, Labeda and Ruan 1986, 35 VP .

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 Fri'tsche.a. N.L. fem. n. Fritschea named after Thomas R. Fritsche, an American physician and parasitologist, in honor of his contributions to our current knowledge on chlamydial diversity. Coccoid to rod‐shaped, nonmotile, obligately intracellular bacteria, up to 2.5 μm in length . Cells show a developmental cycle with morphologically distinct stages similar to those of the Chlamydiaceae . Organisms were found in whitefly and scale insects, but have not yet been obtained in cell culture. The genus is based on the description of “ Candidatus Fritschea bemisiae” and “ Candidatus Fritschea eriococci” (Everett et al., 2005; Thao et al., 2003) (Figure 1). Type species : “ Candidatus Fritschea bemisiae ” Everett, Thao, Horn, Dyszynski and Baumann 2005, 1585.
