The worm, Thelazia callipaeda is transmitted by a fruit fly and is capable of infecting mammals including dogs, cats and humans. Three dogs in the UK have been infected that were imported from Europe. The adult worms live in the mammal’s eyes and the tissues around the eye. The infection manifests itself as mild conjunctivitis to severe corneal ulceration which if left untreated can lead to blindness.
The discovery was made by a research team led by John Graham-/Brown at the University of Liverpool. In light of the fact that so many people travel abroad and import dogs and cats, it is a wise idea to keep this information in mind in the event that you or your pet develops eye problems. With the history of how illnesses are spread, there is no doubt in my mind that it is just a matter of time until this parasite reaches the U.S. and other countries.
