In this case the work focuses on the humble honeybee (Apis mellifera). Since the 1950s, beekeepers in the USA have been using the antibiotic oxytetracycline – a ‘broad-spectrum’ antibiotic that kills most species of bacteria – to prevent infections that can cause ‘foul brood’, a disease that kills bee larvae.  As you can imagine, using a single antibiotic for more than 50 years has led to some selective pressure. In this work, researchers from Yale University were investigating the prevalence of disease resistance in bee gut bacteria.

This might seem like a strange place to look, but it actually has its advantages. Unlike the supremely complex ecosystem of the human gut microbiome, the bee’s is pretty simple, with eight species making up…
