“…In addition to types 1-3, we characterized other small cryptic plasmids (type-4) that share similar genomic composition and arrangements with previously-characterized plasmids of diverse sources (Jesse et al, 2006 ; Miller et al, 2007 ). Most of these plasmids contain the replication initiator protein and some unknown hypothetical proteins.…”

“…Besides these two major types of plasmids (pTet and pVir), various other cryptic plasmids have been identified and fully sequenced (Jesse et al, 2006 ; Miller et al, 2007 ). The plasmid pTIW96 from a wild bird isolate of C. jejuni was 3,860 bp in size with 5 ORFs.…”

“…Two of the ORFs of this plasmid were similar to pCC2228-2 (Hiett et al, 2013 ) found in another C. coli plasmid. Sequence analysis of the two cryptic plasmids of an agricultural isolate of C. coli showed one of the plasmids contained an ORF with homology to a plasmid from C. upsaliensis (Jesse et al, 2006 ). To date, 127 Campylobacter plasmids have been completely sequenced and deposited in GenBank.…”

Campylobacter jejuni and Campylobacter coli are two of the major causes of foodborne illness. In this study, 29 plasmids isolated from 20 retail meat isolates of Campylobacter jejuni and Campylobacter coli were fully-sequenced individually or as a part of a whole genome sequencing approach. The fully-sequenced plasmids ranged in size from 3 to 119 kb. Molecular characterization of the sequenced plasmids was based on pangenomic analysis and types of genes present on these plasmids and similar ones from GenBank. The plasmids were categorized into four different groups. These groups include type-1 that consisted mainly of pTet plasmids with the tetO gene, type-2 plasmids commonly found in C. coli strains, type-3 which has pVir plasmids, and type-4 that consisted mainly of smaller plasmids. The type-2 plasmids were unique, common among C. coli strains, and carried several conjugative transfer genes. The type-2 plasmids were most similar to a plasmid from Helicobacter pullorum. Maximum parsimony analysis and NeighborNet analysis were used to assess the phylogenetic relatedness among the 29 plasmid sequences presented in this study in addition to the other 104 plasmid sequences of Campylobacter species available in GenBank to date. Results from MP analysis revealed multiple lineages among Campylobacter plasmids which was supported by NeighborNet analysis. Clustering of plasmids did not conform to species-specific clades which suggested an intra-species dissemination of plasmids among Campylobacter species. To our knowledge, this is the first extensive phylogenetic analysis of Campylobacter plasmids sequenced to date.
