Resistance on the Rise
Laurence Pope resists the urge to make a pun...
As any good Imperial student knows antibiotic resistant bacteria are a growing threat to human health. The threat has been heightened once again by a recent report produced by the government’s chief medical officer, calling the problem a “ticking timebomb”.
Professor Dame Sally Davies published the second volume of her report earlier this week, urging the government to bring up the issue at the upcoming G8 summit, which the UK holds presidency over this year. She also called for antibiotic resistance to be placed on the government’s National Risk Register of Civil Emergencies, which currently covers such disasters as flooding and terrorist attacks.
No new antibiotics have been introduced into the public domain since 1987
Dame Sally also claimed that pharmaceutical companies need to be encouraged to develop new antibiotics: right now there’s no incentive for pharmaceutical companies to develop them: “antibiotics will only be used for a week or two when they’re needed, and then they have a limited life span because of resistance developing anyway.”
No new antibiotics have been introduced into the public domain since 1987, whilst bacteria have been getting on and developing resistance in the intervening 25 or so years.
The problem has stemmed primarily through antibiotic misuse. Improper use of antibodies, such as not completing a full course or using them for viral infections, destroys a large proportion of the bacterial population. The survivors are then left to replicate. Because these survivors likely had a genetic advantage over the deceased populace this advantage is passed down, resulting in a bacterial population more likely to resist the drug again.
Despite the growing threat the message doesn’t seem to be filtering through properly. Similar pleas have been made by Dame Sally’s predecessors, with warnings of the growing threat spanning back to 1999.

Do you have a source for this?
If drugs entered the public domain sooner, what bearing would this have on drug resistance or pharmaceutical companies' willingness to develop new antibiotics?
Drugs would certainly be available to more people (for instance, in poor and developing countries) so one might predict this would lead to an faster onset of resistance. On the other hand, these drugs may be more carefully administered due to the absence of aggressive marketing from the patent-holding pharmaceutical company. However, this seems to leave less incentive for the pharmaceutical company to develop the drugs in the first place if the window in which the can re-coup R&D costs and turn a profit is reduced. After all, it seems these days pharmaceuticals live and die by their drug patents.
