Heterogeneity of 1.4 МДа plasmids in Salmonella Enteritidis strains

The PCR typing of 100 S. Enteritidis strains containing plasmid 1.4 MDa (2.100 bp) described earlier in microbe strains has been carried out. Its relatedness to S. Enteritidis pJ plasmid from GenBank described in Czech Republic has been revealed. It has been established that this plasmid presents within 16 years in S. Enteritidis strains isolated from patients, food, and environmental swabs at administrative territories of majority of Siberia and the Far East of Russian Federation subjects that confirms its transcontinental distribution.
