On the isolation of TI-plasmid from Agrobacterium tumefaciens [PDF]

, 1976
An efficient lysis method for Agrobacterium cells was developed, which allows a reproducible isolation of the tumor inducing (TI)-plasmid. The lysis method is based on the sensitivity of this bacterium to incubation with lysozyme, n-dodecylamine,EDTA ...

Multiple pathways of plasmid DNA transfer in Helicobacter pylori [PDF]

, 2012
Many Helicobacter pylori (Hp) strains carry cryptic plasmids of different size and gene content, the function of which is not well understood. A subgroup of these plasmids (e.g.

Evidence that the 36kb plasmid of Brachyspira hyodysenteriae contributes to virulence [PDF]

, 2011
Swine dysentery (SD) results from infection of the porcine large intestine with the anaerobic intestinal spirochaete Brachyspira hyodysenteriae. Recently the genome of virulent Australian B. hyodysenteriae strain WA1 was sequenced, and a 36. kilobase (kb)

Plasmid Negative Regulation of CPAF Expression Is Pgp4 Independent and Restricted to Invasive Chlamydia trachomatis Biovars

mBio, 2018
Chlamydia trachomatis is an obligate intracellular bacterial pathogen that causes blinding trachoma and sexually transmitted disease. C. trachomatis isolates are classified into 2 biovars—lymphogranuloma venereum (LGV) and trachoma—which are ...

Co-occurrence of blaNDM–1 and mcr-9 in a Conjugative IncHI2/HI2A Plasmid From a Bloodstream Infection-Causing Carbapenem-Resistant Klebsiella pneumoniae

Frontiers in Microbiology, 2021
Spread of the carbapenemase-encoding and mobilized colistin resistance (mcr) genes among Enterobacteriales poses a great threat to global public health, especially when the both genes are transferred by a single plasmid.

Transformation of the Methylotrophic Actinomycete Amycolatopis methanolica with Plasmid DNA: Stimulatory Effect of a pMEA300-Encoded Gene [PDF]

, 1995
Amycolatopsis methanolica contains a 13.29-kb plasmid (pMEA300) present both in the free state and integrated at a unique genomic location. A pMEA300-free derivative (strain WV1) was selected, allowing further analysis of pMEA300-encoded functions. Whole

Genome characteristics of the optrA-positive Clostridium perfringens strain QHY-2 carrying a novel plasmid type

mSystems, 2023
Clostridium perfringens is a bacterial species of importance to both public and animal health. The gene optrA is the first gene that confers resistance to the tedizolid, a last-resort antimicrobial agent in human medicine.

Antiparallel plasmid-plasmid pairing may control P1 plasmid replication. [PDF]

Proceedings of the National Academy of Sciences, 1991
The copy number of the P1 plasmid replicon is stringently controlled, giving only one or two copies per newborn cell. Control is achieved by the action of the copy-control locus incA, which contains nine repeats of the 19-basepair binding site for the plasmid-encoded initiator protein RepA.
