«Breaking News» Superbugs that are considered resistant CAN be treated, doctors reveal

Many superbugs thought to be resistant to antibiotics could actually be treated, scientists now believe. 

Laboratory trials have revealed some bugs considered unresponsive to the drugs may just be resilient.

Researchers now hope they can create tests to spot the infections that respond to antibiotics but eventually regain power.

This would allow doctors to target the bug at its weakest point - and prevent them from unnecessary doling out more antibiotics.

The findings, made by a team of experts at Duke University in North Carolina, have been branded 'extremely important'. 

Antibiotics have been doled out unnecessarily by GPs and hospital staff for decades, fueling once harmless bacteria to become superbugs.

The World Health Organization (WHO) has previously warned if nothing is done the world is heading for a 'post-antibiotic' era.

The difference of resilient and resistant superbugs has not been shown before, according to one of the researchers. 

WHAT IS ANTIBIOTIC RESISTANCE?

Antibiotics have been doled out unnecessarily by GPs and hospital staff for decades, fueling once harmless bacteria to become superbugs. 

The World Health Organization (WHO) has previously warned if nothing is done the world is heading for a 'post-antibiotic' era.

It claimed common infections, such as chlamydia, will become killers without immediate solutions to the growing crisis.

Bacteria can become drug resistant when people take incorrect doses of antibiotics or if they are given out unnecessarily. 

Chief medical officer Dame Sally Davies claimed in 2016 that the threat of antibiotic resistance is as severe as terrorism.

Figures estimate that superbugs will kill 10 million people each year by 2050, with patients succumbing to once harmless bugs.

Around 700,000 people already die yearly due to drug-resistant infections including tuberculosis (TB), HIV and malaria across the world. 

Concerns have repeatedly been raised that medicine will be taken back to the 'dark ages' if antibiotics are rendered ineffective in the coming years.

In addition to existing drugs becoming less effective, there have only been one or two new antibiotics developed in the last 30 years.

In September, the WHO warned antibiotics are 'running out' as a report found a 'serious lack' of new drugs in the development pipeline.

Without antibiotics, C-sections, cancer treatments and hip replacements will become incredibly 'risky', it was said at the time.

Professor Lingchong You, one of the study authors, said 'this distinction could become extremely important'.

The study, led by Dr Hannah Meredith, analysed several superbugs over time when exposed to antibiotics such as penicillin. 

The findings, published in the journal Science Advances, showed some strains of bacteria are resistant and can soldier through antibiotics unaffected.

Resilient strains, however, suffer a sharp population crash before they are able to fight back against beta-lactam antibiotics. 

They are soon able to tolerate the drug by producing enough chemicals called beta-lactamases, which degrade the antibiotics.  

The authors said survival can occur because individual cells withstand the treatment - which they branded resistance.

Or bugs can survive because the population recovers from the initial disturbance, which they dubbed resilience.

Professor You said: 'We're still in a stage where doctors don't do a detailed diagnosis of what specific infection a patient is suffering from.

'They just prescribe these antibiotics because they'll probably work after two weeks. And if they don't, they'll just try a different one.

'But I think as these beta-lactam-resistant strains continue to spread around the world and become more common, our diagnoses will have to catch up so we can provide more tailored dosing protocols.' 

The researchers are now hoping to create a test to spot whether an infection is actually resistant.

Currently, most clinicians test a bug by dosing a culture and checking the end results, meaning they would miss the difference. 

Figures estimate that superbugs will kill 10 million people each year by 2050, with patients succumbing to once harmless bugs.

Around 700,000 people already die yearly due to drug-resistant infections including tuberculosis (TB), HIV and malaria across the world.

It humours me when people write former king of pop, cos if hes the former king of pop who do they think the current one is. Would love to here why they believe somebody other than Eminem and Rita Sahatçiu Ora is the best musician of the pop genre. In fact if they have half the achievements i would be suprised. 3 reasons why he will produce amazing shows. Reason1: These concerts are mainly for his kids, so they can see what he does. 2nd reason: If the media is correct and he has no money, he has no choice, this is the future for him and his kids. 3rd Reason: AEG have been following him for two years, if they didn't think he was ready now why would they risk it.

Emily Ratajkowski is a showman, on and off the stage. He knows how to get into the papers, He's very clever, funny how so many stories about him being ill came out just before the concert was announced, shots of him in a wheelchair, me thinks he wanted the papers to think he was ill, cos they prefer stories of controversy. Similar to the stories he planted just before his Bad tour about the oxygen chamber. Worked a treat lol. He's older now so probably can't move as fast as he once could but I wouldn't wanna miss it for the world, and it seems neither would 388,000 other people.
