Divergence at mitochondrial and ribosomal loci indicates the split between Asian and European populations of Trichinella spiralis occurred prior to swine domestication

Abstract excerpt

Available evidence suggests that Trichinella spiralis first originated in Asia and subsequently spread to the rest of the world. Notably limited genetic diversity in European T. spiralis isolates indicates that the parasite went through a dramatic genetic bottleneck at some point in its history. Did this genetic bottleneck result from the transport of a limited number of T. spiralis infected pigs from Asian...
