  1. All hosts were collected in harbors or on natural mussel or oyster beds, which were almost all situated in intertidal areas (unless indicated). Nhost: total number of hosts dissected; Nparasites: number of parasites successfully sequenced for cytochrome-c-oxidase 1; Collectors and dissectors: collectors are indicated in italics, dissectors by underlining. Note that no M. intestinalis was found in Pacific oysters in this study, therefore the column representing this host-parasite combination was omitted from the table.
