AI Article Synopsis
- Onchocerca lupi is a parasitic worm infecting the eyes of carnivores, notably reported in dogs in Europe and the USA.
- Researchers used imaging techniques like ultrasound, CT, and MRI to diagnose onchocercosis in two dogs that tested positive for the parasite.
- The findings suggest that ultrasound is particularly effective for diagnosing O. lupi and determining the location of the adult worms within the eye.
Article Abstract
Onchocerca lupi, a zoonotic nematode infecting the eyes of carnivores, has been increasingly reported in dogs from Europe and the USA. In order to improve the current status of knowledge on this neglected filarioid, diagnostic imaging tools (i.e., ultrasound scan, computed tomography and magnetic resonance imaging) are herein used to diagnose canine onchocercosis in two dogs, which scored positive for O. lupi microfilariae at the skin snip test and to assess the anatomical location of the nematode within the ocular apparatus. Results indicate that ultrasound tools are useful to address the diagnosis of O. lupi in dogs and to evaluate the localization of nodules or cysts containing the adult nematode.

Filariasis is recognised as a global public health threat, particularly in tropical and subtropical regions. It is caused by infection with a nematode parasite of the superfamily Filarioidea, including , , , and . Three main types of filariasis have been classified: lymphatic filariasis, subcutaneous filariasis, and serous cavity filariasis.

(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.

Article Synopsis
- Filarioid nematodes are important parasites in dogs, with some species having circulating microfilariae in the bloodstream and others residing in the skin, prompting increased scientific interest, especially concerning zoonotic implications.
- In the US, while a specific filarioid is known as the primary threat, the movement of animals and the diversity of these parasites suggest that skin-dwelling species may be more prevalent than previously thought.
- The review discusses the biology and clinical signs of various filarioid species, the diagnostic methods available, and the need for improved research and surveillance to address knowledge gaps and understand their impact on both canine and human health.
