Those antibiotics you should have finished but didn’t, those painkillers that they gave you way too many of after your surgery, maybe some long-expired vitamins? It’s probably time…

Black and senior patients are more likely to be overprescribed antibiotics, according to a new study of 7 billion trips to healthcare centers — findings that doctors say warrant a further look into unequal prescription practices. Researchers at the University of Texas Health Science Center found that 64% of antibiotic…

By Washington University in St. Louis April 19, 2022 Scientists discovered a potential candidate for antibiotic drug development in a soil bacterium known as Lentzea flaviverrucosa. As drug-resistant and emerging infections become an increasingly serious global health threat, demand for new types of antibiotics is surging. Researchers are racing to…

Illustration of the human gut microbiome. Microbes that safely break down antibiotics could prevent opportunistic infections and reduce the spread of antibiotic resistance.Antibiotics are life-saving drugs, but they can also harm the beneficial microbes that live in the human gut. Following antibiotic treatment, some patients are at risk of developing…

The bacterium that causes acne is becoming resistant to antibiotics, but a study in mice suggests that adding viruses to acne treatments can restore their effectiveness Health 14 April 2022 By Michael Le Page Illustration of phage viruses attacking bacteria Shutterstock / nobeastsofierce It is getting harder to treat acne…

April 13, 2022 – Researchers at Harvard University and the Massachusetts Institute of Technology have created a type of bacteria that could potentially protect humans from the harmful side effects of antibiotics, according to a new study published in the journal Nature Biomedical Engineering. Although antibiotics remain a major tool…

A team of U.S. researchers has discovered a potential candidate for drug development from a rare species of actinomycete bacterium called Lentzea flaviverrucosa.

It does not look like there is going to be any recall of mislabeled beef, but new studies do mean there is more uncertainty at the meat counter. The study findings, published in Science on April 7, mean a label claim that meat products are “raised without antibiotics” or RWA…

fizkes/Shutterstock Antibiotics come in handy at stopping a wide range of bacterial infections, but an unintended consequence of antibody administration is that they also end up harming the benevolent bacteria living in the gut. The human gut has a microbiome on its own that hosts a wide diversity of bacteria,…
