Brevinema andersonii (Brev. i. ne' ma. L. adj. brevis, short; Gr. n. nema, thread; N.L. neut. n. Brevinema, a short thread.) (an.derso'ni.i. N.L. gen. n. andersonii, of Anderson), named for John F. Anderson, who first described the organism.[1] This organism is a Gram-negative, microaerophilic, helical shaped, chemoorganotrophic organism from the genus Brevinema.[2]Brevinema andersonii is host associated, strains have been isolated from blood and other tissues of short-tailed shrews (Blarina brevicauda) and white-footed mice (Peromyscus Zeucopus) and are infectious for laboratory mice and Syrian hamsters.[1][2]B. andersonii is readily identified by restriction enzyme analysis, and SDS-PAGE, or fatty acid composition data. Another identifier for B. andersonii is the sheathed periplasmic flagella in the 1-2-1 configuration. While cells are visible by dark-field or phase-contrast microscopy, they cannot be seen when bright-field microscopy is used.[1]

Brevinema andersonii can be readily identified by enzyme analysis and SDS-PAGE, or fatty acid composition data. An enzyme analysis of B. andersonii showed activity with butyrate, valerate, caproate, caprylate, nonanoate, caprate, esterase lipase, alkaline phosphatase, acid phosphatase, and β-glucuronidase.[1] The fatty acid composition mainly consists of myristic acid(14:0), palmitic acid (16:0), and oleic acid (18:l), and smaller amounts of stearic acid (18:1) and linoleic acid (18:2).[1] There were low levels, less than 1%, of other fatty acids detected. B. andersonii was found to be catalase negative.[1]
