Eleven polymorphic microsatellite loci for the salmonid trematode Plagioporus shawi

We isolated and characterized 11 microsatellite loci from Plagioporus shawi, a parasitic trematode of salmonid fishes (Oncorhynchus spp.). Extensive polymorphism (expected heterozygosities ranging from 0.476 to 0.981 and number of alleles from 10 to 55) was found in a sample of 94 trematodes from 24 infected cutthroat trout (Oncorhynchus clarki) individuals. Nine of the 11 loci will be useful for future genetic studies on within population dynamics of P. shawi.
