“…From this he concluded that the spirilla probably had not originated in the manure itself. Terasaki (175)(176)(177)(178)180) isolated many strains of aquaspirilla from freshwater shellfish but concluded that such spirilla were probably not present as normal or parasitic inhabitants of the mussels but were instead present in the adherent mud (178).…”

“…In some cases enrichment cultures that allowed spirilla to reach numbers sufficiently high to warrant plating on solid media have employed enrichment media that were not di-lute. Such media are exemplified by putrid infusions of freshwater or marine shellfish (175)(176)(177)186), infusion of grass cuttings (30), algal infusions (198), or defined media (88,198). As noted by Williams and Rittenberg (198) and Jannasch (88), spirilla appear to be enriched at the surface of freshwater cultures or just beneath the surface scum that forms in marine cultures.…”

“…Williams and Rittenberg used morphology primarily and nutrition secondarily to divide the genus into 19 species and provided many supplementary physiological data. Since the work of Williams and Rittenberg, a number of additional species have been described (7,19,27,40,41,44). The serological relationships among spirilla, based on thermolabile antigens, have recently been investigated by McElroy and Krieg (24).…”

The morphological, physiological, and nutritional characteristics and the deoxyribonucleic acid (DNA) base compositions of 39 strains of SpirilZum (including the available type strains) were determined. A uniform methodology provided a basis for comparison of the strains. The results, together with previous serological data and with previous results for two strains of Spirillum volutans, indicate that the present genus Spirillum should be divided into three genera, with the original name being restricted to obligately microaerophilic freshwater forms having a large cell diameter and a DNA base composition of 36 to 38 mol % guanine + cytosine (G + C). This genus would contain at present only one species, the type species, S . uolutans. The generic name Aquaspirillum is proposed for the aerobic, freshwater forms having a DNA base composition of 49 to 65 mol % G + C. Although Spirillum Ehrenberg 1832 is one of significance, except for Spirillum minor, the the oldest bacterial generic names and although causative agent of one of the forms of rat-bite spirilla are widespread in freshwater and marine fever in man (3, 8, 29); (ii) difficulty of environments, characterization of this group isolation (7,28,45,49); and (iii) past has not been extensive. This may be attributed difficulties in preservation of cultures, with t o the following factors: (i) lack of medical only continual transfer, the recently developed Contribution no. 3032 of the Woods Hole Oceanographic Institution, Woods Hole, Mass.

Aq.ua.spi.ril' lum . L. aqua water; Gr. n. spira a spiral; N.L. dim. neut. n. spirillum a small spiral; Aquaspirillum a small water spiral. Proteobacteria / Betaproteobacteria / Neisseriales / Neisseriaceae / Aquaspirillum Rigid , helical cells , 0.2–1.4 µm in diameter; however, one species is vibrioid and one species contains straight‐to‐curved rods. A polar membrane underlies the cytoplasmic membrane at the cell poles in all species so far examined for this characteristic by electron microscopy. Intracellular poly ‐β‐ hydroxybutyrate is formed, except in two species. Some species form thin‐walled coccoid bodies, which predominate in cultures of three to four weeks. Gram negative . Motile by polar flagella , generally bipolar tufts ; one species is monotrichous, others have a single flagellum at one or at each pole. Aerobic to microaerophilic , having a respiratory type of metabolism with oxygen as the terminal electron acceptor ; a few species can grow anaerobically with nitrate. The optimal growth temperature for most species is 30–32°C. Chemoorganotrophic ; however, one species is a facultative hydrogen autotroph. Oxidase positive . Usually catalase and phosphatase positive . Indole and sulfatase negative . Casein, starch, and hippurate are not hydrolyzed. No growth occurs in the presence of 3% NaCl. A few species can denitrify. Nitrogenase activity occurs in some species, but only under microaerobic conditions. Carbohydrates are not usually metabolized, but a few species can attack a limited variety. Amino acids or the salts of organic acids serve as carbon sources. Vitamins are not usually required. Usually occur in stagnant, freshwater environments. The mol % G + C of the DNA is : 49–66. Type species : Aquaspirillum serpens (Müller 1786) Hylemon, Wells, Krieg and Jannasch 1973b, 366 (“ Vibrio serpens ” Müller 1786, 48.)
