Virus infections were detected inEctocarpus siliculosus andEctocarpus fasciculatus on the coasts of Ireland, California, Peru, southern South America, Australia and New Zealand; in threeFeldmannia species on the coasts of Ireland, continental Chile and Archipelago Juan Fernandez (Chile); and inLeptonematella from Antarctica. Natural populations on the Irish coast contained 3% infected plants inE. fasciculatus, and less than 1% inFeldmannia simplex. On the Californian coast, 15 to 25% ofEctocarpus isolates were infected. Virus symptoms were absent inE. siliculosus from Peru, but appeared after meiosis in laboratory cultures. The virus particles inE. fasciculatus are identical in size and capsid structure to those reported forE. siliculosus, while the virus inF. simplex is smaller and has a different envelope. Our findings suggest that virus infections are a common and worldwide phenomenon in filamentous brown algae.
