title: pSRD191, a new member of RepL replicating plasmid family from Selenomonas ruminantium.
abstract: A numerous plasmid population was detected in strain 19 of Selenomonas ruminantium. The population was found to consist of six plasmids in size ranging from 1.4 to more than 20kb. The smallest 1.4kb cryptic plasmid pSRD191 was further characterized. Sequence analysis identified a single ORF encoding the 177-residue putative replication protein (Rep191) which shared significant homology with RepL family of replication protein from Firmicutes (staphylococci and bacilli). PCR analysis and Southern hybridisation showed that pSRD191 related plasmids are frequently encountered in rumen selenomonads.
