A Conjugative 'Plasmid' Lacking Autonomous Replication
Autor: Marilyn E. Nugent
Publikováno v: Microbiology. 126:305-310
Attempts were made to isolate open and covalently closed circular DNA from strains containing the IncJ plasmids. All of the methods tried were unsuccessful. It was shown that the IncJ plasmid R391 can integrate into the Escherichia coli K12 chromosom

Use of a modified Escherichia coli trpR gene to obtain tight regulation of high-copy-number expression vectors
Autor: Christopher M. Thomas, William C.A. Tacon, Marilyn E. Nugent, Simon R. Warne
Publikováno v: Gene. 46:103-112
It has been found that with high-copy-number vectors utilising the Escherichia coli trp promoter the amount of represser protein produced from the single chromosomally located trpR gene is inadequate for tight repression to be obtained. An attempt ha

Naturally Occurring Plasmids in Acinetobacter calcoaceticus: pAV2, a Plasmid which Influences the Fertility of the Sex Factor pAV1
Autor: Marilyn E. Nugent, Edward Hinchliffe, Alan Vivian
Publikováno v: Microbiology. 121:411-418
Acinetobacter calcoaceticus strain EBF65/65 harbours a cryptic plasmid, pAV2, which has been shown by electrophoretic separation on agarose gels to have a molecular mass of approximately 13.5 megadaltons (Md). Transfer of the previously described sex

Plasmids and transposons and their stability and mutability in bacteria isolated during an outbreak of hospital infection
Autor: Hilary Richards, Marilyn E. Nugent, Victoria M. Hughes, Naomi Datta
Publikováno v: Plasmid. 2:182-196
In an outbreak of hospital infection caused by Klebsiella aerogenes type K-16 isolates over a 3-month period carried, apparently unaltered, a cryptic 90-Megadalton (Md) plasmid (unclassified) and a multiple-resistance 65-Md plasmid of IncM. The IncM

Characterization and Incompatibility Properties of ROM- Derivatives of pBR322-based Plasmids
Autor: William C.A. Tacon, Terence J. Smith, Marilyn E. Nugent
Publikováno v: Microbiology. 132:1021-1026
Summary: We have characterized a copy number mutant of the pBR322-based plasmid pWT111. A single nucleotide transversion in loop II’ of RNAI results in an eightfold increase in plasmid copy number. Removal of the rom coding region from pWT111cop re

Plasmid Replication and Stability
Autor: Marilyn E. Nugent
Publikováno v: Bacillus ISBN: 9781489935045
The maintenance of bacterial plasmids is dependent on their faithful replication and on their accurate partitioning at cell division. Under defined growth conditions, specific plasmid types are maintained at a characteristic number of copies per chro

Transposable gentamicin resistance in IncW plasmids from Hammersmith Hospital
Autor: Naomi Datta, Marilyn E. Nugent
Publikováno v: Journal of general microbiology. 121(1)
A transposon, Tn733, encoding the gentamicin acetyltransferase AAC(3) was found on two gentamicin R plasmids of IncW at Hammersmith Hospital. Transposon Tn733 has a molecular mass of 5.8 megadaltons and gives a characteristic 2.4 megadalton fragment

pHH502, a plasmid with IncP and IncI alpha characters, loses the latter by a specific recA-independent deletion event
Autor: Kim Ellis, Naomi Datta, Marilyn E. Nugent, David E. Bradley
Publikováno v: Journal of general microbiology. 128(11)
Plasmid pHH502, of molecular weight 70 X 10(6), determined resistance to tetracycline, chloramphenicol, trimethoprim, sulphonamides and mercuric chloride and was incompatible with members of IncP and IncI alpha. It resembled other plasmids of IncI al

A transposon, Tn732, encoding gentamicin/tobramycin resistance
Autor: Naomi Datta, David H. Bone, Marilyn E. Nugent
Publikováno v: Nature. 282:422-423
Gentamicin and tobramycin are important antibiotics in the treatment of hospital infections because of their activity against a wide range of bacterial genera. With their increasing use, bacteria resistant to these drugs have appeared, the resistance
