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.
Trichinosis is often diagnosed in humans once the larvae invade the muscle tissue. Some symptoms include fever, myalgia, malaise, and edema. Trichinosis treatment focuses on reducing inflammation, and corticosteroids are usually administered. This treatment often leads to complete recovery, but muscle pain and weakness may persist.
Treatment of those infected is with the medication ivermectin every six to twelve months. [1] [3] This treatment kills the larvae but not the adult worms. [4] The antibiotic doxycycline weakens the worms by killing an associated bacterium, Wolbachia, and is recommended by some as well. [4] The lumps under the skin may also be removed by surgery ...
Corticosteroids should not be used without concurrent antibiotic treatment or in immunocompromised patients due to the risk of exacerbation of the disease. Currently, there is no published evidence from randomized controlled trials demonstrating that corticosteroids would be an effective adjunct for treating ocular toxoplasmosis.
Corneal ulcers are a common human eye disease. [2] They are caused by trauma, particularly with vegetable matter, as well as chemical injury, contact lenses and infections. Other eye conditions can cause corneal ulcers, such as entropion, distichiasis, corneal dystrophy, and keratoconjunctivitis sicca (dry eye).
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]
Trachoma is an infectious disease caused by bacterium Chlamydia trachomatis. [2] The infection causes a roughening of the inner surface of the eyelids. [2] This roughening can lead to pain in the eyes, breakdown of the outer surface or cornea of the eyes, and eventual blindness. [2]
