Dung beetles as hosts of human protozoan parasites
- Mechanical Transmission of Human Protozoan Parasites by Insects

Dung beetles (Onthophagus spp.) exposed to cat feces containing Toxoplasma gondii released oocysts for 3 consecutive days (26). Furthermore, the oocysts present on the body surface of these beetles remained infectious for several months (26). Also, in the field survey, Isospora oocysts were recovered from dung beetles collected from fecal matter (26). Testing of infectivity of Cryptosporidium parvum oocysts ingested by dung beetles, Anoplotrupes stercorosum, Aphodius rufus, and Onthophagus fracticornis, demonstrated that the oocysts passed unaltered through the mouthparts and gastrointestinal tracts of these beetles (20). Thus, coprophagic beetles can be involved in the epidemiology of cryptosporidiosis by transmission of infective oocysts of Cryptosporidium (20).
