Eshraghiella is a monotypic genus of obligately anaerobic bacteria in the family Lachnospiraceae. Its sole species and type species is Eshraghiella crossota, formerly classified as Butyrivibrio crossotus.[1][2] The type strain was isolated from human feces in Virginia, United States.[3]

Taxonomy

The generic name honours Seyyed Saeed Eshraghi, a microbiologist at the Tehran University of Medical Sciences.[1]

In 2024, Butyrivibrio crossotus was transferred from Butyrivibrio to the newly established genus Eshraghiella. The reclassification was supported by analyses of the 16S rRNA, groEL, recA, and rpoB genes, whole-genome comparisons, and phenotypic differences.[2]

Characteristics

The original species description characterized the cells as Gram-negative-staining, non-spore-forming rods with rounded or slightly tapered ends. Cells were generally curved and occurred singly, in pairs, or in short chains. They measured approximately 0.5–0.7 μm in width and 2–5 μm in length.[4]

Most examined isolates were motile by polar or subpolar tufts of flagella, although nonmotile variants occurred. Growth was poor without a fermentable carbohydrate. Maltose fermentation produced primarily formate, lactate, and butyrate. The reported optimum growth temperature was 37 °C.[4]

The type strain is DSM 2876T (= ATCC 29175T = T9-40AT).[3]
