Jennifer, who is currently in her third year of studying Veterinary Science at the University of Liverpool, was awarded PS5,000 towards her current work on the Oriental eye worm Thelazia
callipaeda, a parasitic infection in dogs, cats and humans which will cause blindness if left untreated.
A: You're correct -- a 26-year-old woman from Oregon discovered that she was infected with Thelazia
gulosa, a parasite commonly known as the cattle eye worm.
An Oregon woman became the first human ever to be infected by a type of eye worm previously seen only in cattle after 14 "Thelazia
gulosa" worms were removed from her eye, reports said Monday. The woman, Abby Beckley, was diagnosed in August 2016 with the genus of nematode worms, which is spread by a type of fly called "face flies," that feed on eyeball lubrication.
Two other types of Thelazia
eye worm infections had been seen in people before, but never this kind, according to Richard Bradbury of the Centers for Disease Control and Prevention.
The parasitic worms - known as the Thelazia
gulosa species - are less than half an inch long each and until now have spread solely among cattle by flies that feed on eyeball lubrication.
The parasitic worm, Thelazia
callipaeda, is spread by a fruit fly and is capable of infecting dogs, cats and human beings.
A good example is Thelazia
callipaeda (Spirurida, Thelaziidae) nematode infections in children and elderly persons living in rural and poor communities in countries in Europe and Asia (2).
is an important spirurida nematode of cattle, buffalo, sheep, goat, horse, dog and man.
Two types of Spirurida nematodes are identified as parasites of the eye in avian species, Oxyspirura and Thelazia
. The genus Oxyspirura includes approximately 70 species, from which O.
* Parasitic conjunctivitis is rare in North America, but in some cases bot fly larvae or, in the Western United States, the parasitic worm or nematode Thelazia
californiensis can inhabit the conjunctival sac between eye and eyelid.
Haemonchus and Trichostrongylus were the most frequently recorded genera followed by Chabertia, Oesophagostomum, Schistosoma, Moniezia, Cooperia, Bunnostomum, Toxocara, Ostertagia, Nematodirus, Trichuris, Strongyliodes, Avitellina, Fasciola, Thelazia
(n=02), Syngamus, Gaigeria, Skrjabinema, Cotylophoron, Metastrongylus and Gongylonema as mixed or single species infections in different species of animals.
