Plasmid pJW1 from Selenomonas ruminantium subsp. lactilytica strain JW13 has been cloned in Escherichia coli vector pBluescriptSK(-) and completely sequenced. The plasmid is only 1410 bp with an overall GC content of 42.2%. Computer analysis of sequence data revealed a single open reading frame (ORF1, 146 amino acids, MW 16,525.5 Da) encoding a putative replication protein which is similar to the Rep protein of Ruminobacter amylophilus plasmid pRAO1. ORF1 is followed by a long AT-rich (75%) region and a region abundant in direct and inverted repeats. Comparison of DNA sequences revealed the presence of a short (<250 bp) DNA segment which is highly conserved between several small S. ruminantium plasmids including pJDB21.

D020357	Selenomonas	Curved bacteria, usually crescent-shaped rods, with ends often tapered, occurring singly, in pairs, or short chains. They are non-encapsulated, non-sporing, motile, and ferment glucose. Selenomonas are found mainly in the human buccal cavity, the rumen of herbivores, and the cecum of pigs and several rodents.
