Selenomonad
The genus ''Selenomonas'' constitutes a group of motile crescent-shaped bacteria within the Veillonellaceae family and includes species living in the gastrointestinal tracts of animals, in particular the Ruminants. A number of smaller forms discovered with the light microscope are now in culture but many, especially the large selenomonads are not, owing to their fastidious and incompletely known growth requirements. ==Gram stain==
The family ''Veillonellaceae'' was transferred from the order ''Clostridiales'' to the new order ''Selenomonadales'' in the new class ''Negativicutes''.〔 Despite most of the members of the ''Firmicutes'' staining positive for the Gram stain and being trivially called "low-GC Gram-positives" (''c.f.'' Bacterial phyla), members of the ''Negativicutes'' stain Gram-negative and possess a double bilayer.〔 This transfer now appears to have been mistaken.〔Yutin N, Galperin MY (2013) A genomic update on Clostridial phylogeny: Gram-negative spore formers and other misplaced ''Clostridia''. Environ Microbiol 〕 On further examination the Selenomonads appear to be members of the ''Clostridia''.
