(PhysOrg.com) -- The arms race between effective antibiotic prophylaxis and closely related strains or species of bacteria is continually escalating. Bacteria can quickly develop genetic resistance to a range of antibiotic ...
(PhysOrg.com) -- Genes jumping between bacteria are rather common which in part explains their ability to rapidly develop immunity to antibacterial agents. What’s not so common are examples of genes jumping between animals ...
(PhysOrg.com) -- Much as people can exchange information instantaneously in the digital age, bacteria associated with humans and their livestock appear to freely and rapidly exchange genetic material related to human disease ...

(PhysOrg.com) -- A new study suggests that genes are transferred from one micro-organism to another up to a hundred million times more frequently than previously thought.
More than a thousand microbial genomes have been sequenced at various sequencing centers in the past 15 years to better understand their roles in tasks ranging from bioenergy to health to environmental cleanup. Conservative ...
