Bacteriophages, or viruses that infect bacterial pathogens, may also act as vectors of virulence or of antibiotic resistance genes, ultimately making bacterial disease worse for the host.

To find out if their guess was right, Levin, Schrag, and Perrot made some of the drug - resistant bugs susceptible again by replacing their resistance gene with a gene that conferred sensitivity.
The genes encoding NDM - 1 and other antibiotic resistance factors are usually carried on plasmids — circular strands of DNA separate from the bacterial genome — making it easier for them to spread through populations.
Hyperthermophilic composting, therefore, has the potential to make composting end products safer by reducing the abundance of unwanted antibiotic resistance genes.
The researchers, led by Dr Charles Wondji, used a wide range of methods to narrow down how the resistance works, finding a single mutation in the GSTe2 gene, which makes insects break down DDT so it's no longer toxic.
That background makes it important to characterize «both the natural occurrence of the antibiotic - resistance genes and the anthropogenic load, and where those genes come from, and it's good to do it in a quantitative way,» as Pruden's team did for the South Platte, says Joakim Larsson of the University of Gothenburg, Sweden, who has tracked antibiotics and resistance genes in India and Sweden.
With a human strain showing widespread resistance as well — and the fact that pandemic viruses may arise when avian and human strains swap genes — makes it even less appealing, says Bright.
Companies selling Bt seeds hope to avoid that in part by designing plants that make more than one Bt toxin, but this strategy may not work if resistance to several toxins is tied to a single gene, says Tabashnik, who is now at the University of Arizona.

Dr Melita Gordon, from the University of Liverpool's Institute of Infection and Global Health, said: «Importantly, the antibiotic resistance genes, which have previously been carried on a separate genetic package, have now been incorporated into the main chromosome of the bacteria itself, which is likely to make it easier for the Typhoid strain to retain these resistance genes.»
They successfully pinpointed the exact spot in the chromosomal structure that is home to the genes which makes it drug - resistant, known as an antibiotic resistance island.
