Intestinal protists in the gut microbiome are increasingly studied, but their basic epidemiology is not well understood. We explored the prevalence, genetic diversity, and potential zoonotic transmission of two protists colonizing the large intestine - sp. and - in 37 species of non-human primates (NHPs) and their caregivers in six zoos in the Czech Republic.

Article Synopsis
  • Non-human primates (NHPs) are facing population declines due to various threats, including diseases caused by parasites, bacteria, and viruses.
  • Strongylid nematodes are common parasitic infections in NHPs, but their diversity is hard to study due to mixed infections not being distinguishable by traditional methods.
  • This study used advanced metagenomics techniques to analyze strongylid infections in NHPs from Malaysia and Japan, finding that the communities in Asian NHPs may be less diverse than those in African NHPs, providing key data for monitoring NHP health.

Cestodes of the family Anoplocephalidae parasitize a wide range of usually herbivorous hosts including e.g. rodents, ungulates, primates, elephants and hyraxes.

Primates are an important source of infectious disease in humans. Strongyloidiasis affects an estimated 600 million people worldwide, with a global distribution and hotspots of infection in tropical and subtropical regions. Recently added to the list of neglected tropical diseases, global attention has been demanded in the drive for its control.

, a cosmopolitan gastrointestinal protist, is detected mainly in patients with clinical giardiasis in high-income countries. In contrast, there is very little information on the presence of in asymptomatic individuals. Therefore, the aim of this study was to determine the presence and prevalence of in gut-healthy volunteers in the Czech Republic and to perform a comparative evaluation of different diagnostic methods, since diagnostics is complicated.
