Exposure and susceptibility underlie every organism's infection status, and an untold
diversity of factors can drive variation in both. Often, both exposure and susceptibility change …

Background The parasite composition of wild host individuals often impacts their behavior
and physiology, and the transmission dynamics of pathogenic species thereby determines …

Currently, disgust is regarded as the main adaptation for defence against pathogens and
parasites in humans. Disgust's motivational and behavioural features, including withdrawal …

Fleas are one of the most interesting and fascinating taxa of ectoparasites. All species in this
relatively small order are obligatory haematophagous (blood-feeding) parasites of higher …

The fundamental role of the major histocompatibility complex (MHC) in immune recognition
has led to a general consensus that the characteristically high levels of functional …

Plague causes periodic epizootics that decimate populations of prairie dogs
(PDs)(Cynomys), but the means by which the causative bacterium (Yersinia pestis) persists …

Wild animals have parasites that can compromise their physiological and/or behavioural
performance. Yet, the extent to which parasite load is related to intraspecific variation in …

Pathogen‐mediated selection is thought to maintain the extreme diversity in the major
histocompatibility complex (MHC) genes, operating through the heterozygote advantage …

Male-biased parasite loads, which are common in vertebrates, could be a consequence of
sexual selection, and for species that group, the costs of parasites could vary with group size …

Zoonotic pathogens that cause devastating morbidity and mortality in humans may be
relatively harmless in their natural reservoir hosts. The tick-borne bacterium Borrelia …
