“…Eiken (1958) isolated similar organisms from abscesses, mostly of the buccal region, and named them Bacteroides corrodens. Subsequently there were sporadic reports of B. corrodens from abscesses (Reinhold, 1966), gingival crevice samples and blood cultures after tooth extraction (Khairat, 1967), and diseased tonsils (Schroter and Stawru, 1970). These early reports are difficult to interpret because no distinction was drawn between those corroding strains that were strict anaerobes and those that were C02-dependent and facultatively anaerobic.…”

“…These include : buccal abscesses (Eiken, 1958) ; periodontal disease (Khairat, 1967 ;Duerden et al, 1987) and other oral infections (Schroter and Stawru, 1970;Duerden et al, 1982); soft tissue infection and ulcers, especially peripheral (e.g., varicose) ulcers and gangrene, and ulcerative conditions of the perineum and external genitalia (Labbt: et al, 1977;Duerden et al, 1982;Masfari et al, 1983Masfari et al, , 1985. Fontaine et al (1982,1984) used refined anaerobic transport and culture methods to isolate strains, subsequently confirmed as B. ureolyticus (Fontaine et al, 1986;Taylor et al, 1986) from urethral samples from men with non-gonococcal, non-chlamydia1 urethritis ; successful treatment with metronidazole further supported a pathogenic role for B. ureolyticus in these patients (Hawkins et al, 1988).…”

Summary. Clinical isolates of corroding, gram-negative, anaerobic bacilli (provisionally identified as Bacteroides ureolyticus) from superficial ulcers and soft tissue infections (1 9, non-gonococcal, non-chlamydia1 urethritis (1 2) and adult periodontal disease (14) were compared with reference strains of B. ureolyticus, B. gracilis and Wolinella recta in a series of conventional tests of morphology, biochemical activity, tolerance of dyes and bile salts, and antibiotic sensitivity, gas-liquid chromatographic analysis of metabolic products, and in whole-cell analysis by pyrolysis-mass spectrometry (Py-MS). A numerical taxonomic approach was used with the results of conventional tests and the grouping obtained was compared with that obtained by Py-MS. All the ulcer and soft-tissue isolates and the urethritis isolates were oxidaseand urease-positive and formed a homogeneous set consistent with the reference strain of B. ureolyticus. The dental isolates differed from B. ureolyticus strains and were heterogeneous amongst themselves. None corresponded with the reference strains of B. gracilis or W . recta. The conventional and Py-MS approaches to c haracterisation produced similar groupings and each distinguished between a single cluster of ulcer-urethritis strains and several clusters of dental strains, although the dendrograms derived from the two approaches differed in the order of the clusters; in the Py-MS dendrogram one subcluster of four dental strains came within the main ulcer-urethritis cluster and a cluster of five ulcer strains was separated as a distinct group.

Ei.ke.nel' la . M.L. dim. ending ‐ ella ; M.L. fem. n. Eikenella named after M. Eiken, who first named the type species of the genus. Proteobacteria / Betaproteobacteria / Neisseriales / Neisseriaceae / Eikenella Straight rods, 0.3–0.4 × 1.5–04.0 µm, unbranched, with rounded ends and a regular morphology. Short filaments are occasionally formed. Nonsporeforming. Gram negative. Nonmotile , possessing no flagella; however, a “twitching motility” may occur on agar surfaces. Facultatively anaerobic . Optimal growth temperature, 35–37°C. Colonies may appear to corrode the surface of the agar ; noncorroding strains may also occur. Nonhemolytic; a slight greening of blood media around colonies may occur. Oxidase positive (Kovacs method). Negative for catalase , urease , arginine dihydrolase , and indole . Lysine‐decarboxylase positive . Nitrates are reduced to nitrites. No acid is formed from glucose or other carbohydrates . Hemin is usually required for growth under aerobic conditions . Occur in the human mouth and intestine; can be opportunistic pathogens. The mol % G + C of the DNA is : 56–58. Type species : Eikenella corrodens (Eiken 1958) Jackson and Goodman 1972, 75 ( Bacteroides corrodens Eiken 1958, 415.)
