The effect of Trichinella spiralis infection on the mechanical properties of the mammalian diaphragm.

abstract：:Genome assemblies can form the basis of comparative analyses fostering insight into the evolutionary genetics of a parasite's pathogenicity, host-pathogen interactions, environmental constraints and invasion biology; however, the length and complexity of many parasite genomes has hampered the development of well-resol...
