The present work uses fossils and subfossils to decipher the origin and evolution of terrestrial pathogens and endoparasites. Fossils, as interpreted by morphology or specific features of their hosts, furnish minimum dates for the origin of infectious agents, coevolution with hosts, and geographical locations. Subfossils, those that can be C14 dated (roughly under 50,000 years) and are identified by morphology as well as molecular and immunological techniques, provide time periods when humans… 

The ecological role of microsymbionts in the interaction of plants and herbivorous insects

The obtained data show that the understanding of the mechanisms underlying the interaction of plants and pathogens or pests is incomplete without knowledge about the role of “hidden players,” microsymbionts that are present in both parties.

Parasitoid biology preserved in mineralized fossils

This work examines 1510 phosphatized fly pupae from the Paleogene of France and identifies 55 parasitation events by four wasp species, providing morphological and ecological data and highlighting the need to investigate ecological data preserved in the fossil record.

Estimated divergence times of Hirsutella (asexual morphs) in Ophiocordyceps provides insight into evolution of phialide structure

The results showed that certain phialide characteristics of Hirsutella were phylogenetically informative for two groups of taxa, and suggested that a common origin allowed for diversification of given clades into separate niches.

Fossil Record of Viruses, Parasitic Bacteria and Parasitic Protozoa

It is clear that invertebrate and vertebrate viruses were well established by the mid-Cretaceous and many of these pathogens resemble those being transmitted today to a range of vertebrate hosts by arthropod vectors.

Review of Information on Eocene Entomopathogenic Hypocreales (Ascomycota)

Abstract A single cordycipitoid fungus on a bark louse in Baltic amber and the scars of a death-grip from an ant infected by cordycipitoid fungus on a leaf from Messel, are known from the Eocene.

Glomalean fungi from the Ordovician.

Fossilized fungal hyphae and spores from the Ordovician of Wisconsin strongly resemble modern arbuscular mycorrhizal fungi (Glomales, Zygomycetes), indicating that Glomales-like fungi were present at a time when the land flora most likely only consisted of plants on the bryophytic level.

Out of Africa: origins of the Taenia tapeworms in humans

Phylogenetic and divergence date analyses indicate that the occurrence of Taenia tapeworms in humans pre–dates the development of agriculture, animal husbandry and domestication of cattle (Bos spp.)

It is clear that prehistoric peoples in the Americas were host to a variety of human parasites, some of which were not previously thought to be present before historic times.

Trichuris eggs in animal coprolites dated from 30,000 years ago.

Results indicate that K. rupestris was a host for an unknown Trichuris species not found in this rodent presently, and climate changes that occurred by 10,000 yr ago in the region could be the cause of its disappearance.

Evidence of intestinal parasites of dinosaurs

Protozoan cysts and helminth eggs preserved in a coprolite from the Early Cretaceous Bernissart Iguanodon shaft in Belgium demonstrate that representatives of 3 phyla parasitized dinosaurs by that

First Fossil Record of Endoparasitism of Adult Ants (Formicidae: Hymenoptera) by Braconidae (Hymenoptera)

This discovery of a parasitoid wasp larva emerging from an adult ant in Eocene Baltic amber shows that ant parasitism by Braconidae was well established some 40 million years ago.

A fossil smut fungus from the anthers of an Eocene angiosperm

This unequivocal fossil of the Ustilaginales shows that at least 48 million years ago the order had representatives with anthericolous sori, a characteristic of some extant smut taxa that permits effective insect dispersal of the fungus among populations of specific host plants.

Evidence of vector-borne disease of Early Cretaceous reptiles.

The present study identifies these blood cells as reptilian and describes putative developing amastigotes inside spherical to oval whitish vacuoles within some of the fossil blood cells.
