A case of subconjunctival infection with a zoonotic species of Onchocerca is described, in a 16-year-old Albanian man who had immigrated to Greece. This is the first report of human infection with Onchocerca in this tissue location and only the eighth report of zoonotic Onchocerca in man.

Following the successful eradication of , there are now just three species of conventional microfilaremic human filarial parasites endemic to the Brazilian Amazon region: , and The zoonotic filarial parasite is also found in the Amazon region as are several sylvatic filarial parasites, some of which have been recorded causing zoonoses and some of which have never been recorded outside the region. is only found in the Amazonia onchocerciasis focus in the Brazilian state of Roraima where it affects the people of the Yanomami tribe living around the densely forested Venezuela border region. is by far the most common filarial parasite in Brazil and has a broad but patchy distribution throughout the western Amazon region.

Background: Filarial worms are important vector-borne pathogens of a large range of animal hosts, including humans, and are responsible for numerous debilitating neglected tropical diseases such as, lymphatic filariasis caused by Wuchereria bancrofti and Brugia spp., as well as loiasis caused by Loa loa. Moreover, some emerging or difficult-to-eliminate filarioid pathogens are zoonotic using animals like canines as reservoir hosts, for example Dirofilaria sp.

(Rodonaja, 1967) is an understudied, vector-borne, filarioid nematode that causes ocular onchocercosis in dogs, cats, coyotes, wolves, and is also capable of infecting humans. Onchocercosis in dogs has been reported with increasing incidence worldwide. However, despite the growing number of reports describing canine cases as well as zoonotic infections globally, the disease prevalence in endemic areas and vector species of this parasite remains largely unknown.
