Thelazia callipaeda
Thelazia callipaeda
Thelazia callipaeda (pronounced: the-laz-ia cal-li-pae-da), also known as the oriental eye worm, is a species of parasitic nematode that infects a variety of mammalian hosts, including humans. The species is primarily found in Asia and Europe.
Etymology
The genus name Thelazia is derived from the Greek word "thelazein", which means "to suckle", referring to the parasitic nature of the species. The species name callipaeda is derived from the Greek words "kallos", meaning "beauty", and "pais", meaning "child". This is likely a reference to the relatively small and delicate nature of the parasite.
Life Cycle
The life cycle of Thelazia callipaeda involves several stages, including the larval stage, the pupal stage, and the adult stage. The parasite is transmitted to the host through the bite of an infected fruit fly, which serves as the intermediate host.
Symptoms and Treatment
Infection with Thelazia callipaeda can lead to a condition known as Thelaziasis, which is characterized by symptoms such as eye irritation, conjunctivitis, and in severe cases, blindness. Treatment typically involves the removal of the worms from the eye, often followed by the administration of antiparasitic medication.
