ABSTRACT DNA sequence analysis of five IncW plasmids (R388, pSa, R7K, pIE321, and
pIE522) demonstrated that they share a considerable portion of their genomes and allowed …

Leading article their associated components, gene cassettes, are known to have been
constituents of the first resistance plasmids reported in the mid 1960s. That apparently …

Abstract New IncQ R plasmids, pIE639 and pIE723, are characterized and compared to the
prototype IncQ plasmid RSF1010. Additional resistance determinants not common on other …

Many multiresistance plasmids and transposons of gram-negative bacteria carry related
DNA elements that appear to have evolved from a common ancestor by site-specific …

We have investigated molecular relationships and evolution of plasmids classified
genetically to incompatibility (Inc) group X, in particular by comparison of plasmids from the …

This chapter provides an overview of plasmid classification systems and then describes the
various mechanisms of plasmid‐mediated resistance to antibacterial agents. The major …

The IncP-1β plasmid pB8, which confers resistance to amoxicillin, spectinomycin,
streptomycin, and sulfonamides, was previously isolated from a sewage treatment plant. It …

Conjugative plasmid transfer is one of the major mechanisms responsible for the spread of
antibiotic resistance and virulence genes. The incompatibility (Inc) 18 group of plasmids is a …

IncL/M-type plasmids R446b and R471a were originally isolated from Morganella morganii
(formerly Proteus morganii) as the first members of the IncL/M group of multidrug resistance …

Antibiotic resistance genes are spread mostly through plasmids, integrons (as a form of
gene cassettes), and transposons in gram-negative bacteria. We describe here a novel …
