Scientists discovered a revolutionary antibiotic class to tackle superbugs

Uppsala University scientists have discovered a new class of medicines, marking a big step forward in the fight against antibiotic resistance, a rising global health concern.

This significant study, published in the Proceedings of the National Academy of Sciences, introduces antibiotics that target LpxH, a protein essential in the synthesis of Gram-negative bacteria's protective outer layer, such as Escherichia coli and Klebsiella pneumoniae.

The World Health Organization has designated these bacteria as priority targets for novel treatments due to their resistance to current antibiotics.

This discovery is enormously significant. Antibiotics have revolutionized healthcare and saved many lives.

However, overuse and misuse of these therapies has resulted in a surge in antibiotic-resistant bacteria, leaving many current antibiotics ineffective and jeopardizing the fundamental foundation of medical treatments as we know them.

The novel antibiotic family has strong action against multidrug resistant bacteria and has showed potential in treating bloodstream infections in mice.

What distinguishes these chemicals is their unique method of action, which targets a route in bacteria that is not utilized by current antibiotics. This means there is no pre-existing resistance to this new class, which provides a new armament in the fight against superbugs.

The road from discovery to clinical use is lengthy and difficult, with more research and development required. Nonetheless, the preliminary findings offer a source of hope.

This work was part of the EU project ENABLE, a collaboration between academia and pharmaceutical businesses across Europe to improve the development of novel antibiotics.

The continuance of this study under ENABLE-2 demonstrates a commitment to solving the problems posed by antibiotic resistance.

This research has far-reaching ramifications beyond infection treatment. Antibiotics prevent bacterial infections, allowing medical treatments such as cancer treatment, surgery, and premature baby care to proceed.

The development of a new class of antibiotics raises the prospect of maintaining these life-saving therapies in the face of growing antibiotic resistance.

As the world grapples with the antibiotic resistance challenge, the Uppsala University team's discovery serves as a reminder of the importance of innovation and international collaboration in ensuring the future of healthcare.

Cutting calories may reduce cellular ageing and increase lifetime.

State College, Pennsylvania — Penn State researchers are presenting fresh persuasive data linking diets to ageing. Their study focused on telomeres, the genetic "end caps" that protect our chromosomes, and how calorie restriction impacts them. The scientists studied data from a two-year trial of caloric restriction in humans and published their findings in the journal Ageing Cell. They discovered that those who restricted their calories lost telomeres at different rates than the control group. Despite this, both groups concluded the research with roughly identical telomere lengths. Previous research found that reducing calories by 20 to 60 percent resulted in prolonged life for a variety of species. When a person's cells split, some telomeres are lost as chromosomes are copied to a new cell. The cell's telomeres are then shortened in total. The telomere cap eventually disappears as cells divide. The genetic information on the chromosome becomes more vulnerable to de...

DUI without alcohol? A rare syndrome in the intestines may be the culprit.

Imagine you are a police officer. You see a car swerving all over the road. You pull over the driver, and they are plainly inebriated. They insist, with slurred speech, that they haven't consumed any alcohol all day. Do you believe them? In 2024, a Belgian man was acquitted after being arrested three times for DUI in four years. Though his position at a brewery raised suspicions, he asserted that he had not been drinking. Three doctors confirmed that he had auto-brewery syndrome and was ignorant. People with this illness have microorganisms in their intestines that produce abnormally high levels of alcohol when they break down sugars and carbs. Though it is an uncommon condition, a lady was acquitted of a DUI conviction in 2016 after being diagnosed with the same syndrome. Her blood alcohol level was four times the legal limit. I am a microbiologist who is fascinated by how the gut microbiome influences human health. As the author of the book "Pleased to Meet Me: Genes, G...

Kidney infection vs. UTI: Key Differences and Treatment

Urinary tract infections (UTIs) and kidney infections are both connected health disorders, but they affect different sections of the urinary system and require different treatment strategies. Understanding each condition's symptoms, causes, treatment choices, and prognosis might help you manage it more successfully. A UTI is an infection that affects any component of the urinary system, including the bladder, urethra, ureters, and kidneys. Most infections affect the lower urinary tract, specifically the bladder and urethra. Women are more likely than men to acquire a UTI because their urethra is shorter, making it simpler for bacteria to enter the urinary tract. A kidney infection, also known as pyelonephritis, is a kind of UTI that typically begins in the bladder or urethra and spreads to one or both kidneys. This condition is more problematic than a lower UTI because it can result in more severe consequences. Symptoms: UTI symptoms often include a strong, persistent urge t...
