Scientists have found evidence of antibiotics – one a suspected human carcinogen – in seafood imported into the United States and purchased from grocery store shelves.

The common antibiotic, amoxicillin-clavulanate, may improve small bowel function in children experiencing motility disturbances, according to a new study.

Scientists report that male pseudoscorpions treated with the antibiotic tetracycline suffer significantly reduced sperm viability and pass this toxic effect on to their untreated sons. They suggest that a similar effect could occur in humans and other species.

Researchers could change the playing field of human versus bacteria. Scientists have identified pathways of naturally occurring molecules in our bodies that can enhance antibiotic performance.

Researchers have now discovered that floc – “goo-like” substances that occur suspended in water and that host large communities of bacteria – also contain high levels of antibiotic resistance.

EPFL chemists have shown how the three-dimensional shape of an antibiotic changes when it is in an aqueous environment. This could lead to a better understanding of how drugs interact with biological molecules.

Large quantities of antibiotic-resistant bacteria enter the environment via municipal – and especially hospital – wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous – multiresistant – strains appear to withstand or even to be promoted by treatment processes.

Food-borne diseases might soon have another warrior to contend with, thanks to a new molecule discovered by chemists. The new antibiotic, an analog of the widely used food preservative nisin, also has potential to be a boon to the dairy industry as a treatment for bovine mastitis.

A new study describes how bacteria use a previously unknown means to defeat an antibiotic. The researchers found that the bacteria have modified a common "housekeeping" enzyme in a way that enables the enzyme to recognize and disarm the antibiotic.

Treatment with the antibiotic vancomycin increases the severity of allergic asthma in young mice, researchers in Canada have revealed. The results are consistent with the “hygiene hypothesis” that links the loss of beneficial bacteria in the community of microorganisms in the gut, collectively known as the microbiota, to the onset ...
