Replication of IncB and other plasmids

Grant number: 299816


Plasmids are additional mini-chromosomes carried by many bacteria. They carry information that enables their hosts to prosper in otherwise hostile environments. Plasmids spread rapidly between bacteria, efficiently disseminating plasmid-borne information throughout bacterial populations. Many plasmids carry information that increases the virulence of their host. The emergence of multi-drug resistant bacteria and the rapid spread of the information enabling bacteria to withstand most antibiotics available today, were mediated by plasmids. Plasmids also carry information that ensures their own survival. Consequently, their hosts retain the plasmids even when it is no longer beneficial for them..
