A genus of gram-negative, aerobic or microaerophilic, colorless filaments. It is nonfruiting, motile by gliding, and found in freshwater sediments and cow dung. One species (V. stercoraria) is considered morphologically to be a streptobacillus. That species is strictly aerobic and produces a homodimeric bacterial hemoglobin, especially under oxygen-limited growth conditions. (From Bergey's Manual of Determinative Bacteriology, 9th ed) |
