S neathia

Abstract

Sneath'i.a. N.L. fem. n. Sneathia named after the British microbiologist Peter H. A. Sneath, in recognition of his outstanding contributions to microbial systematics. Fusobacteria / Fusobacteriia / Fusobacteriales / Leptotrichiaceae / Sneathia Gram‐stain‐negative , asporogenous, rod‐shaped bacteria ; nonmotile. Cells may display pleomorphism, and filaments may be observed. Anaerobic , although some strains may show poor growth in CO 2 . Fermentative metabolism. Acid but no gas is produced from glucose . Acid is not produced from ribose or maltose. Lactic acid, formic acid, and minor amounts of acetic acid are the end products of glucose metabolism; succinic acid may be produced. Fastidious ; requires serum or blood for growth. Optimum temperature for growth 35–37°C. Catalase and oxidase negative. Esculin and hippurate are hydrolyzed but starch is not. β‐Glucuronidase is produced. Indole is not produced. Voges–Proskauer negative. Nitrate is not reduced to nitrite. DNA G + C content (mol%) : 22–25 [derived from genomic data (dfgd)]. Type species : Sneathia sanguinegens Collins, Hoyles, Törnqvist, von Essen and Falsen 2002, 687 VP (Validation List no. 85) (Effective publication: Collins, Hoyles, Törnqvist, von Essen and Falsen 2001, 360).
