Trichinosis, also known as trichinellosis, is a parasitic disease caused by roundworms of the Trichinella genus. [1] During the initial infection, invasion of the intestines can result in diarrhea, abdominal pain, and vomiting. [1]
Trichinella spiralis is a viviparous [1] nematode parasite, occurring in rodents, pigs, bears, hyenas and humans, and is responsible for the disease trichinosis. It is sometimes referred to as the "pork worm" due to it being typically encountered in undercooked pork products. It should not be confused with the distantly related pork tapeworm.
Trichinella is the genus of parasitic roundworms of the phylum Nematoda that cause trichinosis (also known as trichinellosis). Members of this genus are often called trichinella or trichina worms . A characteristic of Nematoda is the one-way digestive tract, with a pseudocoelom (body cavity made up of only an ectoderm and endoderm ).
Currently, eight species of Trichinella are known, [1] only three of which cause trichinellosis, and Trichinella britovi is one of them. [2] Numerous mammal species, as well as birds and crocodiles, [1] [2] can harbor the parasite worldwide, but the sylvatic cycle is mainly maintained by wild carnivores. [2] [3] [4]
A special variant is ocular larva migrans where usually T. canis larvae travel to the eye. Only a few roundworm eggs are necessary to cause larva migrans in human children or adults. However, visceral larva migrans seems to affect children aged 1–4 more often while ocular larva migrans more frequently affects children aged 7–8.
There are many diseases known to cause ocular or visual changes. Diabetes , for example, is the leading cause of new cases of blindness in those aged 20–74, with ocular manifestations such as diabetic retinopathy and macular edema affecting up to 80% of those who have had the disease for 15 years or more.

Loa loa is a filarial (arthropod-borne) nematode (roundworm) that causes Loa loa filariasis. Loa loa actually means "worm worm", but is commonly known as the "eye worm", as it localizes to the conjunctiva of the eye. Loa loa is commonly found in Africa. [2] [page needed] It mainly inhabits rain forests in West Africa and has native origins in ...
