Cloning and transposon insertion mutagenesis of virulence genes of the 100-kilobase plasmid of Salmonella typhimurium.
We have cloned regions of the 100-kilobase (kb) plasmid, pStSR100, of Salmonella typhimurium SR-11 that confer virulence to plasmid-cured S. typhimurium. Cells carrying recombinant plasmids that conferred virulence were selected by inoculating mice orally with recombinant libraries in virulence plasmid-cured S. typhimurium and harvesting isolates that infected spleens. Three plasmids, pYA401, p...
متن کاملVirulence-associated genetic regions comprising 31 kilobases of the 230-kilobase plasmid in Shigella flexneri 2a.
By random transposon Tn5 insertions, we previously identified six virulence-associated SalI fragments, B, D, F, G, H, and P, in the 230-kilobase plasmid pMYSH6000 of Shigella flexneri 2a. In this study, we analyzed the sites of 134 independent Tn5 insertions on four contiguous SalI fragments, B, P, H, and D, of pMYSH6000 and identified five virulence-associated regions; four were associated wit...
متن کاملComplete nucleotide sequence and genetic organization of the 210-kilobase linear plasmid of Rhodococcus erythropolis BD2.
The complete nucleotide sequence of the linear plasmid pBD2 from Rhodococcus erythropolis BD2 comprises 210,205 bp. Sequence analyses of pBD2 revealed 212 putative open reading frames (ORFs), 97 of which had an annotatable function. These ORFs could be assigned to six functional groups: plasmid replication and maintenance, transport and metalloresistance, catabolism, transposition, regulation, ...

15 صفحه اولMinimal replication origin of the 200-kilobase Halobacterium plasmid pNRC100.
We have identified the replication origin of pNRC100, a 200-kb plasmid of Halobacterium halobium, by assaying for replication ability of miniplasmids containing cloned fragments of pNRC100 and the mevinolin resistance selectable marker of Haloferax volcanii. First, we showed the replication ability of plasmid pNGHCMEV1, which contains the 19-kb HindIII-C fragment of pNRC100, by recovery of plas...
