IncFII-like plasmids are mostly considered as virulence plasmids, such as pYV harboring type III secretion system (yops), that can be present alone or co-resident and compatible with other FII-positive resistance plasmids
(typable by the FII, FIA, FIB, FIC loci) within the same bacterial cell (24) (http://pubmlst.
Plasmids in Gram negatives: molecular typing of resistance plasmids
Conjugative trimethoprim or trimethoprim and kanamycin resistance plasmids
with lengths of 80 to 110 kb were present.
Transfer of antimicrobial resistance plasmids
from Klebsiella pneumoniae to Escherichia coli in the mouse intestine.
Resistance genes are either carried on the chromosomes of wild-type bacteria or on elements of extachromosomal, sometimes extraneous origins, such a resistance plasmids
and transposons (8).
Transfer of multiple drug resistance plasmids
between bacteria of diverse origin in natural microenvironments.
The presence of resistance plasmids
(R-plasmids) is a significant feature of this organism (15,16).
Other workers reported that transmission of resistance plasmids
of Escherichia coli from poultry to human intestines commonly occurs (Tabatabaei and Nasirian, 2003).
Among globally disseminated pathogens, HGT facilitates combination of the most effective antibiotic resistance genes from diverse geographies into multidrug resistance plasmids
that spread between strains.
There is an urgent need for expanded resistance surveillance for carbapenemase-producing organisms and their resistance plasmids
in food products that are not captured under current programs.
Replicon typing through a published multiplex PCR system revealed a replicon I1 from the Tn6092harboring resistance plasmids
in SC-B134 and SC-B136 (Table 1; Figure 2, panel C) (10).
