A new study from the Mitreva lab sheds light on the relationship between the liver fluke Fasciola hepatica and its bacterial endosymbiont, Neorickettsia. Researchers found that while these bacteria are widely present in fluke populations across the Americas and Europe, they show low genetic diversity and strong geographic patterning. Their results suggest a complex evolutionary history shaped by […]
