We performed a parallel assessment of population genetics and demography of two species of pinworms with different degrees of host specificity (Trypanoxyuris multilabiatus, species-specific; and T. minutus, genus-specific) and their host, the mantled howler monkey (Alouatta palliata), based on mitochondrial DNA sequences and microsatellite loci (these only for the host). Given that pinworms and primates have a close co-evolutionary history, covariation in several genetic aspects of their populations is expected.<h4>Results</h4>Mitochondrial DNA revealed two genetic clusters (West and East) in both pinworm species and howler moBMC ecology and evolutionCo-structure analysis and genetic associations reveal insights into pinworms (Trypanoxyuris) and primates (Alouatta palliata) microevolutionary dynamics.PMC8527708IN202819Solorzano-Garcia BPinero DPerez-Ponce de Leon GVazquez-Dominguez EfalseCo-structure analysis and genetic associations reveal insights into pinworms (Trypanoxyuris) and primates (Alouatta palliata) microevolutionary dynamics.<h4>Background</h4>In parasitism arm race processes and red queen dynamics between host and parasites reciprocally mold many aspects of their genetics and evolution.
