Full-text available
Mites from the Demodecidae and Psorergatidae can optimally use mammalian hosts by inhabiting a number of different microhabitats in their skin. Hence, in individual hosts, several species of parasites from these groups have been described in different microhabitats. There are few data on their co-occurrence either at the host species level or at th...

Parasites are very widely distributed in the environment and form complex relationships with their hosts, forming host-parasite systems. They have various life strategies, either parasitizing on the body of the host (ectoparasites) or inside it (endoparasites). They can form both permanent, often long-term, and temporary relationships and can demon...

Capelin Mallotus villosus, a representative of the Osmeridae, is a common species found in the North Atlantic, Pacific and Arctic Ocean. Being one of the main components of the diet of various fish species, it plays an important role in the circulation of different parasite species, including the nematodes of the Anisakidae. Capelin is also extensi...

A greater understanding of mite biodiversity and ecology can explain their preference for microhabitats within host bodies, i.e., as ecto-, meso-, and endoparasites. Similarly, learning about the patterns formed by mite communities in wild animals can shed light on the mechanisms of parasitosis development in their domesticated counterparts. Hence,...

The Demodecidae are skin and tissue parasites of mammals with high host, topical, and topographic specificity. They may cause a demodecosis, typically observed in pets and humans. Numerous mammal species have been found to have several, specific demodecids, which inhabit different microhabitats. Thus far, two species have been known from the domest...
