Trematodes of the order Diplostomida are well known as serious pathogens of man, and both farm and wild animals; members of the genus Schistosoma (Schistosomatidae) are responsible for human schistosomosis affecting more than 200 million people in tropical and subtropical countries, infections of mammals and birds by animal schistosomes are of great veterinary importance. The order Diplostomida is also rich in species parasitizing other major taxa of vertebrates. The Aporocotylidae are pathogenic in fish, Spirorchiidae in reptiles. All these flukes have two-host life cycles, with asexually reproducing larvae usually in molluscs and occasionally in annelids, and adults usually live in the blood vessels of their vertebrate hosts. Pathology is frequently associated with inflammatory reactions to eggs trapped in various tissues/organs. On the other hand, the representatives of Diplostomidae and Strigeidae have three- or four-host life cycles in which vertebrates often serve not only as definitive, but also as intermediate or paratenic hosts. Pathology is usually associated with migration of metacercariae and mesocercariae within the host tissues. The impact of these trematode infections on both farm and wild animals may be significant.

The recent research of the authors was supported by the project “Centre for Research of Pathogenicity and Virulence of Parasites” (No. CZ.02.1.01/0.0/0.0/16_019/0000759) funded by European Regional Development Fund and Ministry of Education, Youth and Sports of the Czech Republic, Czech Science Foundation grant (No. 18-11140S), and Charles University institutional support (PROGRES Q43, UNCE/SCI/012—204072/2018, and SVV 260432/2018). We appreciate helpfulness of our colleagues at different institutions (Dr. S. V. Brant, Prof. I. Dyková, Dr. R. Iglesias, Mgr. T. Macháček, Dr. M. Ondračková, Dr. L. Panská, Dr. R. Salamatin, Dr. J. Sitko, Dr. M. Soldánová) who provided samples and/or photos of helminths mentioned in our chapter (see their affiliations in the figure legends), and colleagues at the Institute of Parasitology, Biology Center of the Czech Academy of Sciences (Prof. T. Scholz, Doc. R. Kuchta, Dr. B. Škoríková) who enabled us to take photos of helminths in the Helminthological Collection.
