In this work, we investigated parasites of the firebug Pyrrhocoris apterus in Austria and demonstrated that in addition to the extensively studied Leptomonas pyrrhocoris, it can also be infected by Blastocrithidia sp. and by a mermithid, which for the first time has been characterized using molecular methods. This diversity can be explained by the gregarious lifestyle, as well as the coprophagous and cannibalistic behavior of the insect hosts that makes them susceptible to various parasites.

- Trypanosomatids, such as Leptomonas pyrrhocoris, are parasitic flagellates that can harbor various RNA viruses, some of which may impact diseases in humans, like leishmaniasis.
- The study found that 60% of the surveyed cultures of L. pyrrhocoris contained multiple double-stranded RNA fragments and identified four viral groups, including both previously known and new species.
- The results imply notable viral diversity within a single protist species, showcasing the potential for viral reassortment and evolutionary patterns in trypanosomatid-associated viruses.
Tatra chamois ( (Blahout 1972)) and Tatra marmot ( (Kratochvíl 1961)) are significant endemic subspecies of the subalpine and alpine ranges of the Tatra Mountains in Central Europe. In four studied localities in the range of their typical biotopes in Slovakia and Poland, we investigated intestinal parasites of Tatra chamois and Tatra marmots, with an emphasis on anoplocephalid tapeworms. We also studied the occurrence, species diversity, and abundance of oribatid mites as intermediate hosts thereof, and the prevalence of cysticercoid larval stages of anoplocephalid tapeworms in collected oribatids using morphological and molecular methods.

In terms of health hazards for these animals, an important role is played by parasitic infections that can lead to a significant depletion of the entire population.
Objective: The aim of the study was to describe the occurrence of gastrointestinal parasites of Tatra chamois in the current environmental and climatic conditions of the High Tatra Mountains.
