Machine learning reveals metabolic pathways disrupted by the drugs, offering new targets to combat resistance. Most antibiotics work by interfering with critical functions such as DNA replication or construction of the bacterial cell wall. However, these mechanisms represent only part ...Continue reading
MIT engineers repurpose wasp venom as an antibiotic drug: Altered peptides from a South American wasp’s venom can kill bacteria but are nontoxic to human cells
The venom of insects such as wasps and bees is full of compounds that can kill bacteria. Unfortunately, many of these compounds are also toxic for humans, making it impossible to use them as antibiotic drugs. After performing a systematic ...Continue reading
With these nanoparticles, a simple urine test could diagnose bacterial pneumonia: Results could also indicate whether antibiotics have successfully treated the infection
Pneumonia, a respiratory disease that kills about 50,000 people in the United States every year, can be caused by many different microbes, including bacteria and viruses. Rapid detection of pneumonia is critical for effective treatment, especially in hospital-acquired cases which ...Continue reading
Probiotics and antibiotics create a killer combination, delivered together the two join forces to eradicate drug-resistant bacteria.
In a new study, the researchers showed that by delivering a combination of antibiotics and probiotics, they could eradicate two strains of drug-resistant bacteria that often infect wounds. To achieve this, they encapsulated the probiotic bacteria in a ...Continue reading
