Ancient diversity in host-parasite interaction genes in a model parasitic nematode

The paper sequenced genomes of two parasitic nematodes, found high genetic diversity in host-interaction genes, and suggests long-term balancing selection maintains this diversity.

The impact of within-host coinfection interactions on between-host parasite transmission dynamics varies with spatial scale

The paper examines how within-host parasite interactions affect between-host transmission dynamics, finding localized effects for some species but not others.

Long-term temporal trends in gastrointestinal parasite infection in wild Soay sheep

This study examines 31-year trends in gastrointestinal parasite prevalence and abundance in wild Soay sheep, finding independent effects of host density and year on parasite dynamics.

The impact of resource provisioning on the epidemiological responses of different parasites

This study develops and applies epidemiological models to show how resource provisioning affects different parasites based on their life-history traits and transmission modes.

Who acquires infection from whom? Estimating herpesvirus transmission rates between wild rodent host groups

The paper estimates herpesvirus transmission rates between wild rodent host groups using population dynamic models applied to field data on naturally infected wood mice.

Experimental parasite community perturbation reveals associations between Sin Nombre virus and gastrointestinal nematodes in a rodent reservoir host

The paper experimentally perturbs parasite communities in rodent hosts to show that reducing nematode infection increases Sin Nombre virus seroprevalence and improves survival in co-infected mice.

Spatiotemporal variation in drivers of parasitism in a wild wood mouse population

This study investigates how environmental, host, and within-host factors influence nematode infection intensity in wood mice, finding that season, body condition, and sex are key determinants with varying effects over time.

Supplemented nutrition increases immunity and drug efficacy in a natural host-helminth system

This study shows that dietary supplementation improves immunity and anthelmintic efficacy in wood mice infected with Heligmosomoides polygyrus in both wild and captive settings.
