The prevalence of Marteilia refringens parasitising Mytilus galloprovincialis from natural beds in Ría de Vigo (NW Spain) was monitored for one year. Individuals taken from the inner part of the Ría were the only ones to be found to be infected, ranging between 3.33 and 26.67%. Mussels from the outer part of the Ría were M. refringens-free.
