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.

Stepping Up Response to Curb Infectious Diseases in Nigeria

Abuja - In Nigeria, vulnerable populations, especially those in underserved communities, remain at high risk of infectious diseases, including Lassa fever—an acute viral hemorrhagic illness caused by the Lassa virus. Endemic in Nigeria, Lassa fever continues to affect thousands annually, with the dry season (December–April) being the peak transmission period. In 2024, the disease has been particularly severe, with 1,059 confirmed cases reported across 28 states, resulting in 175 deaths (16.6% case fatality rate). Alarmingly, 35 healthcare workers have been infected during the outbreak, underscoring the urgent need for robust infection prevention measures. The Lassa virus is primarily transmitted to humans through exposure to food or household items contaminated with the urine or feces of infected Mastomys rats. Secondary transmission can occur through direct contact with the bodily fluids of infected individuals, posing significant risks to healthcare and laboratory workers who la...

According to a study, thousands of South Asian persons in the United Kingdom may receive erroneous type 2 diabetes tests.

Diabetes UK, research type 2 diabetes. New research, which will be discussed tomorrow at the Diabetes UK Professional Conference 2024, has uncovered a genetic variation that is almost unique to people of South Asian descent and impacts the accuracy of the diabetes haemoglobin A1c (HbA1c) test. This test measures the average blood sugar level during the past two to three months. It is critical for diagnosing type 2 diabetes, tracking prediabetes, and determining diabetic management. South Asians with this genetic variation may have artificially low HbA1c values, delaying the diagnosis of type 2 diabetes. Dr Miriam Samuel of Queen Mary University London and colleagues in the Genes & Health Research Team identified a genetic variant that is found in 7.6 percent of people of South Asian heritage but is rare in other ethnicities using genetic and health data from the Genes & Health study (over 60,000 individuals of Bangladeshi or Pakistani ethnicity living in England) and the UK...
