Abstract:
The nucleotide sequence has been determined of a small cryptic plasmid of Salmonella Typhimurium, designated pIMVS1, which correlated with an outbreak of gastroenteritis. This plasmid has a size of 3357 bp with no known functions. It does not encode any protein products but shows homology to several well-characterized plasmids. The replication system with RNAI and RNAII and the replication origin (oriV) is highly similar to that of plasmid p15A. It also has a putative mobilisation origin similar to that of ColE1.
