NewsMicroplastics changing gut microbiomes of wild seabirds
An international team of scientists has found evidence that microplastics in the digestive tract of seabirds altered the microbiome of the gut – increasing the presence of pathogens and antibiotic-resistant microbes, while decreasing the beneficial bacteria found in the intestines.
