This article reviews research on the evolutionary mechanisms leading to different
transmission modes. Such modes are often under genetic control of the host or the …

Parasitic organisms account for a large portion of living species. They have arisen on
multiple independent occasions in many phyla, and thus encompass a huge biological …

Parasites have evolved independently in numerous animal lineages, and they now make up
a considerable proportion of the biodiversity of life. Not only do they impact humans and …

Although interest in Acanthocephala seems to have reached only a small community of
researchers worldwide, we show in this opinion article that this group of parasites is …

Rotifera comprise about 2,000 species (Segers 2007) of microscopic animals, usually much
less than 1 mm in length, characterized by the presence of a ciliated corona and a muscular …

Phylogenetic relationships among Syndermata have been extensively debated, mainly
because the sister-group of the Acanthocephala has not yet been clearly identified from …
