Blautia fusiformis is a species of Gram-positive, obligately anaerobic bacteria in the genus Blautia . It was isolated from human feces and first described as a novel species in 2022. [1]
The species epithet fusiformis derives from Latin fusus (spindle) and forma (shape), reflecting the spindle-shaped morphology of its cells. [1] Based on 16S rRNA gene sequencing, Blautia fusiformis is most closely related to Blautia obeum , sharing approximately 96.8–97.1% sequence identity. [1]
Blautia fusiformis forms short, rod-shaped cells approximately 1.5–2.5 µm in length, tapering slightly at the ends (spindle-shaped morphology). Growth occurs anaerobically on modified Gifu anaerobic medium. [1]
Blautia fusiformis is commonly found in the intestinal microbiota of humans (detected in 69–70% of human gut samples), pigs (55–56%), chickens (~50%), wastewater (~47–54%), and activated sludge (~40–52%). [1]
The type strain, CLA-AA-H217T (= DSM 112726T), was isolated from the feces of a healthy 26-year-old woman. Another recognized strain, CLA-AA-H275 (= DSM 113286), was isolated from the feces of a healthy 30-year-old man. [1]
