Resistance transfer factor (shortened as R-factor or RTF) is an old name for a plasmid that codes for antibiotic resistance. R-factor was first demonstrated in Shigella. Often, R-factors code for more than one antibiotic resistance factor: genes that encode resistance to unrelated antibiotics may be carried on a single R-factor, sometimes up to 8 different resistances. Many R-factors can pass from one bacterium to another through bacterial conjugation and are a common means by which antibiotic resistance spreads between bacterial species, genera and even families. For example, RP1, a plasmid that encodes resistance to ampicillin, tetracycline and kanamycin originated in a species of Pseudomonas, from the Family Pseudomonadaceae, but can also be maintained in bacteria belonging to the family Enterobacteriaceae, such as Escherichia coli.
Transmission
Bacteria containing F-factors (said to be "F+") have the capability for horizontal gene transfer; they can construct a sex pilus, which emerges from the donor bacterium and ensnares the recipient bacterium, draws it in, and eventually triggers the formation of a mating bridge, merging the cytoplasms of two bacteria via a controlled pore. This pore allows the transfer of genetic material, such as a plasmid. Conjugation allows two bacteria, not necessarily from the same species, to transfer genetic material one way. Since many R-factors contain F-plasmids, antibiotic resistance can be easily spread among a population of bacteria. Also, R-factors can be taken up by "DNA pumps" in their membranes via transformation, or less commonly through viral mediated transduction,or via bacteriophage, although conjugation is the most common means of antibiotic resistance spread.They contain the gene called RTF(Resistance transfer factor).

However, few studies have confronted this issue in humans and disclosed the intrinsic mechanisms. This work aimed to establish whether intestinal insulin resistance modifies lipid and lipoprotein homeostasis in the intestine of obese subjects.

- Derepressed Transfer Properties Leading to the Efficient Spread of the Plasmid Encoding Carbapenemase OXA-48.
- Potron A, Poirel L, Nordmann P.Author information INSERM U914, Emerging Resistance to Antibiotics, Faculté de Médecine et Université Paris-Sud, K. Bicêtre, France.AbstractThe current emergence of the carbapenemase OXA-48 among Enterobacteriaceae is related to the spread of a single IncL/M-type plasmid, pOXA-48a. This plasmid harbors the blaOXA-48 gene within a composite transposon, Tn1999, which is inserted into the tir gene, encoding a transfer inhibition protein. We showed that the insertion of Tn1999 into the tir gene was involved in a higher transfer frequency of plasmid pOXA-48a. This may likely be the key factor for the successful dissemination of this plasmid.
