> The researchers then checked snot from hospitalized patients. Of 187 samples, all but one were colonized by either S. aureus or S. lugdunensis
> S. lugdunensis, was killing S. aureus. Its weapon of choice? A small compound dubbed lugdunin
> The German researchers who performed the study have filed a patent for lugdunin
Are we really allowing people to patent naturally occurring biological compounds these days? Shouldn't the patent be for specific treatments derived from their findings on lugdunin, not the compound itself?
Barring lugdunin from being patented while providing no public funding would incentivise this group to withhold publication until they thought they'd found every commercially-reasonably derivation.
Now independent researchers won't want to touch lugdunin because they'll need to license the patent, however they won't know whether licensing the patent is worthwhile until they do their research. This will prevent further research, not encourage it.
It carries too high of a risk for financially-minded people (looking for a return on investment) to throw money at it.
As opposed to the risk of searching for some completely new thing that may not exist?
That's only true in the case of commercial R&D. For non-commercial (academic) research, the funding is normally through a grant mechanism (not company supported). Academic research is almost never concerned with the licensing/patent issues aside from "can I run my experiment". It is common for academic labs to use drugs that are still "in the pipeline" for experiments.
The exception, at least in US law, is super-super slim
Maybe a company will find a new mechanism of action when they look at analogs? Maybe a less toxic version? Maybe the lead compound fails but the backups work?
Patents don't prevent compounds from being explored in research. If this is anything like other discoveries, companies will start looking at lugdunin very closely.
What is it's mechanism of action? Can the structure be optimized? What else could it be used for?
Other antibiotics have been patented and that didn't stop companies from doing the research and tweaking the structure to make it even better.
From this image of the structure (http://cen.acs.org/content/dam/cen/94/31/09431-notw4-Lugduni...) it looks very much like some kind of small pore. That's a total guess, of course, but a cyclic peptide with alternating chirality looks reasonable, although a little small at only 7 residues.
Worst is when American companies charge U.S. customers higher prices than overseas consumers for drugs that were developed using USA-taxpayer-funded research.
For a simple example, an academic or non-profit group might get reduced cost access to research materials and software.
Also, publicly-funded research may have a mix of funding sources, including private philanthropy and for-profit companies.
Ever seen the video with Ron Paul being asked a question with what should happen to a person who has no insurance but needs immediate medical care and the audience shouted "Let him die!". There's your answer.

I'll take researchers for $1,000, Alex.
Not a knock to drug manufacturers who are simply acting as they should under the current profit-driven system, but I think we'd be far better off if more of this existential-level stuff (like health) were government functions, or at least government sponsored and not-for-profit.
So, let's support a federation of researchers who have direct incentive for discovery. Then, let's make those discoveries public domain.
Not quite. Arguing that Space X is no better would be following a red herring and arguing that there are no similarities is too high a standard. A valid counterargument merely needs to show that they are sufficiently different in some important way.
And, my (admittedly pithy) counterargument ran exactly along those lines.
Meanwhile, the main difference between the domains had already been pointed out in my original comment, and I even provided an example of a relevant domain.
So, you've gotten it exactly backwards: the burden is on my respondent to demonstrate why SpaceX is a relevant analogy/counterargument.
Cool I choose heaps of public funding and patents dead forever!
This is the sort of thing that requires and international treaty.
Unfortunately many universities (and hence researchers) are under pressure to commercialise their IP, based on the assumption that such behaviour is beneficial to the economy.
1. Get a patent, find a commercial partner and investors who will give you a ton of money to develop it in the hopes of getting a return.
2. Make it public domain, remove any financial incentive to develop it, then try and convince whoever to give you hundreds of millions of dollars to develop it without any hope of financial return?
The folks I know who work in generics complain about the razor thin margins.
So yes, this research has been paid for by the German public. However, it is common for universities to apply for patents. Revenue from patent licensing is then usually shared between the university and the researchers.

Its not a "choose a system" kind of deal. It never has been. It always been state funded research + investment supported by patents + university funds + non-profit funds + additional government funded incentives. The question we should ask is if this specific incentive is needed together with all the other incentives in order to create a end user product that will saves lives sometime in the future.
Having said that, a patent for general anti-biotic+matter is probably valid and it's unlikely that this compound will be used for much else.
They'll probably make some money out of it, to fund more research, but hopefully any deal with pharmaceutical companies should have some pricing clause to make this widely affordable to public health services.
I would expect the patent to be on the process for isolating or synthesizing the compound.
They filed for a patent under the European patent regime, right?
Treat them with care this time round
And then we get to complain about the excess bureaucracy in healthcare!
It's possible to find middle ground, and I think comprehensive IT systems for all doctors with real-time forbidden drugs lists and epidemia tracking would make this much easier.
It's even possible to divide hospitals into "different drug is forbidden here", and when someone has MRSA - put him in a hospital where the drugs that doesn't work on him - are banned anyway. And use "last ditch" drugs only in these hospitals.
And of course the main thing is to stop abusing antibiotics for agriculture.
That's said I am under convinced it would overwhelm hospitals. Hospitals seem overwhelmed to me because A&E is a faster and more efficient way "into" the system than community based care or other approaches.
The common case is elderly care - almost no funding for in home nursing help, hard to get through the process, and elderly struggle on until a manageable chronic complaint turns acute, leading to ambulance, A&E admittance and a struggle for scare beds in wards. Whereas the hospital probably could have been avoided through treatment at home / locally.
Until we pay for community systems we won't relive the pressure on hospitals. And this out centre of excellence will just be fire fighting.
(Excuse the sudden rant - not sure where that came from :-)

Here's a particularly frustrating example.
http://bjgp.org/content/early/2016/07/05/bjgp16X686125
> Acute infective conjunctivitis is common among preschool children. Public Health England (PHE) recommends that children with conjunctivitis do not need to be excluded from child care, but childcare providers are required to determine their own sickness policies and prior research suggests that children are often excluded until they are treated or have recovered. How the content of these policies impacts on prescribing decisions has not been quantified.
[...]
> Acute infective conjunctivitis (AIC) is a common condition in preschool children.1 It is usually mild and self-limiting, often with no requirement for treatment or a doctor’s appointment.2 Evidence suggests, however, that parents and guardians are advised by childcare providers (CPs) to take their children with conjunctivitis to their GP for assessment.3–5 Furthermore, some CPs will not permit affected children to return to child care until antibiotics have been prescribed,3,4,6,7 thus parents are obtaining antibiotics to get their child readmitted. A situation in which antibiotics are prescribed for non-clinical reasons is difficult to justify and requires further investigation.
> Although most cases (50–75%) of AIC are bacterial in origin,8 the aetiology is difficult to determine clinically and only 36% of doctors are confident in differentiating between viral and bacterial conjunctivitis.9,10 In bacterial conjunctivitis, there may be some clinical benefit obtained from topical antibiotics;11 however, this benefit is perhaps not seen in children and topical chloramphenicol shortens the duration of symptoms by only 0.3 days.2 Despite this, most clinicians usually prescribe antibiotics for AIC.10
So a similar study in a few years might lead to a new antibiotic molecule targetting the mutated S. aureus.
Is there hope for this or is it nonsense?
Other than that, the idea is perfectly viable.
How does S. aureus prevent S. lugdunesis from invading?
And then we had 4. We discovered new ones, at one point I believe up to 7. But resistance made it go down pretty much by one per decade, but each next one ended faster. And then it hit zero, in 2012 I believe.
Now we may (maybe) be back up to one. Big whoop. Not going to last.
The problem is that evolution is out-researching us, the problem is that we're losing the war, not any particular battle. Antibiotics used to last 3-5 decades. Now we're down to years. While we do find new antibiotics on a regular basis, the problem is the speed of adaptation. The problem is that science is losing/has lost the "battle with darkness" as it was called 700 years ago. We are now in the situation that there are people dying because they entered hospitals for unrelated reasons (where they were exposed to these bacteria).
The problem is that we need to let millions of people die of curable diseases constantly or risk a Spanish flu like incident that can be reasonably expected to kill somewhere between 500 million and a billion humans today.
Not the case at all. Biggest use of antibiotics today is in food production(agriculture etc.), not in hospitals. And it's also completely unregulated.
"The problem is that evolution is out-researching us"
Evolution also has a simple rule: "Use it or lose it". So don't be afraid. There are ways around acquired immunity.
I think the FDA might disagree with you on that point.
Completely false - antibiotic (and all drug) use in animals is absolutely regulated in nearly all countries, including the US [1,2,3]. Said regulations may not be what you'd like, but to claim they don't exist is silly.

It seems to be possible, in Italy they use 50 times more antibiotics per pig than here in Sweden, due to the stricter regulation. Denmark is doing good but still uses twice as much as in Sweden.
This is due to our regulations, and it costs more to keep the pigs healthy, but due to EU:s strict trade rules, there are no way we can protect our farmers from the cheaper meat.
And somehow Italian ham is considered to be of higher quality...
From your second link:
"In the U.S., about 80 percent of antibiotics are used for livestock and 20 percent for humans"
The bottom line is that we need to use newly developed antibiotics more carefully, continue researching new ones, and no Spanish flu like incident will happen (even without considering that the Spanish flu was a virus, not a bacterium).
That would suggest that we need a few more antibiotics to cycle though, by the time we get back to the older ones they will be efficient again.
