Introduction
Pseudoselenomonas ruminantium HD4
Pseudoselenomonas ruminantium HD4 was isolated from bovine rumen contents in the USA [1] and characterised along with other Selenomonas strains [2]. HD4 is an anaerobic bacterium that ferments a broad range of carbohydrates and produces primarily propionate, and acetate. Lactate is fermented [2] and HD4 can reduce nitrate, sulfate and fumarate.
The draft genome for HD4 (3,116,786 bp) was generated through the Hungate1000 project with JGI [3]. A 4.8 kb plasmid has been reported from HD4 [4] and a 4,899 bp plasmid was predicted from the draft genome sequence. Resequencing gave a genome of 3,180,636 bp consisting of a 2,987,729 bp chromosome and a 192,907 bp plasmid.
NCBI: Pseudoselenomonas ruminantium.
GTDB: Selenomonas_A ruminantium_D. HD4 belongs in a different species group than the type strain of P. ruminantium (GA192, DSM 2150).
Risk group: 1.
