Q & A

Why is our medical system heavily reliant on antibiotics?

Antibiotics are crucial for treating infections, protecting people during surgeries, and supporting cancer treatments. They have significantly extended life expectancy and improved healthcare outcomes.

What could be the consequences of a world without effective antibiotics?

A world without effective antibiotics would resemble the past, where many people died from infections. Surgical procedures and treatments for diseases like cancer would become much riskier, and infections from minor injuries could be fatal.

How did the discovery of antibiotics impact healthcare?

The discovery of antibiotics transformed healthcare by making the treatment of infections straightforward, reducing mortality rates, and extending life expectancy by an average of 20 years.

What challenges do we face with antibiotic resistance?

Antibiotic resistance poses a significant health threat as bacteria evolve to resist existing treatments. The lack of new antibiotics in the past 30 years exacerbates this issue, making infections harder to treat.

What is the significance of Alexander Fleming's discovery of penicillin?

Alexander Fleming's discovery of penicillin was a groundbreaking moment in medicine, as it was the first effective antibiotic that saved countless lives by killing bacteria without harming the host.

Why is antibiotic resistance becoming a more serious issue today?

Overuse and misuse of antibiotics, such as using them without prescriptions, have accelerated the development of antibiotic-resistant bacteria. This has created a growing health crisis that could lead to millions of deaths annually by 2050.

How can individuals help combat antibiotic resistance?

Individuals can help by not requesting antibiotics unnecessarily, completing the full course of prescribed antibiotics, and raising awareness about the importance of responsible antibiotic use.

What are the main challenges in developing new antibiotics?

Finding new classes of antibiotics is challenging because it is easier to modify existing ones than to discover entirely new treatments. This requires significant funding and research efforts to identify effective strategies.

Why is there a need for more awareness and funding for antibiotic research?

Increased awareness and funding are essential to pressure governments and companies to invest in research to combat antibiotic resistance and develop new treatments, preventing a potential global health crisis.

What is the 'post-antibiotic apocalypse' and its potential impact on food chains?

The 'post-antibiotic apocalypse' refers to a scenario where antibiotics no longer work, leading to widespread illness in humans, animals, and plants. This would severely disrupt food production and safety, causing a global crisis.

Transcripts

Our entire medical system really relies on antibiotics.

This would be the biggest health crisis

that we've experienced this century.

We don't hear about it. But it's already here.

Nobody is safe, until we're all safe.

What would a world without antibiotics look like?

Well, I think it would look a lot like the past,

where a lot of people would die younger than they do now.

Just think about war -

more people died of infections and their wounds,

than died actually on the battlefield.

The discovery of various classes of antibiotics in the 20th Century

had a profound impact on health care.

So treatment of infection suddenly became very straightforward,

and it's something that we benefit a lot from today.

Antibiotics protect people during operative surgery -

Caesarean sections, replacement joints, let alone cancer treatments.

Antibiotics added, on average, 20 years life to everyone.

We went to the hospital, the emergency room.

They said they gave him a broad spectrum antibiotic.

And then they took me to another room and they're like,

"Your son has an infection. We don't know the source."

We were in the ICU with like 10 doctors,

and they said he wasn't really going to make it.

At that point, I knew that he was dead.

I could feel it.

And that's when we learned that Simon had contracted

an antibiotic resistant bacterium, a superbug.

And I had never heard of any of this.

Alexander Fleming's discovery of penicillin was immense.

Noticing that in a petri dish where bacteria were growing,

there were white areas where the bacteria were not growing.

And he realised that something had happened.

He looked and found the fungus, penicillin -

our first effective antibiotic that saved masses of lives.

Most antibiotics come from soil and fungi.

When I expose bacteria to antibiotics,

they're going to become resistant,

which is very bad because we haven't discovered

a new antibiotic in the last 30 years.

Growing up back in Mexico,

you didn't need a prescription to get an antibiotic.

You had a little bit of a sore throat,

you go to the pharmacy and get an antibiotic.

And that only gives more and more chances to these bugs

to acquire mutations to become resistant.

The situation today is more serious than people realise.

It's actually the first real study looking at all the data -

494 million patient records -

to model what is happening.

It is predicted that by 2050,

10 million people are going to die every year

from complications with superbugs or resistant microbes.

So we really have to find alternative strategies

to fight against these bugs.

A world without antibiotics -

I sometimes call it "the post-antibiotic apocalypse" -

would impact on our food chain too,

because animals would get ill, plants would get ill and die.

We would really be in the most dreadful mess.

As an individual, I think one of the most important things

is don't ask for antibiotics if they are not offered to you.

If you are prescribed antibiotics,

then make sure you finish the course of antibiotics that you're given.

Because if you don't finish the course,

even if you're feeling better,

there might be some residual infection

that could become resistant.

We have probably found the easy-to-find antibiotics.

But that doesn't mean there are not many more to be found.

If we keep recycling the same old treatments,

then the problem is just going to exacerbate.

One of the main bottlenecks with antibiotic research

is that the easiest thing to do

is to look at the structures of existing antibiotics,

and modify those slightly to try to overcome the resistance.

It's much more challenging to find a completely new class of antibiotics.

So we have to fund quite widely in order to be able to identify

those strategies that are going to work best.

I think if there were more awareness

then there would be more general pressure from society

on governments and on companies

to fund more research into targeting this problem.

We should be anticipating problems,

and doing something about them before they become

enormous global crises.
