Toxocara canis (T. canis, also known as dog roundworm) is a worldwide-distributed helminth parasite that primarily infects dogs and other canids, but can also infect other animals including humans. [ 1 ] [ 2 ] The name is derived from the Greek word toxon 'bow, quiver' and the Latin word caro 'flesh'. [ 3 ]
Human parasites are divided into endoparasites, which cause infection inside the body, and ectoparasites, which cause infection superficially within the skin. The cysts and eggs of endoparasites may be found in feces, which aids in the detection of the parasite in the human host while also providing the means for the parasitic species to exit ...
Toxocariasis is an illness of humans caused by the dog roundworm (Toxocara canis) and, less frequently, the cat roundworm (Toxocara cati). [1] These are the most common intestinal roundworms of dogs, coyotes, wolves and foxes and domestic cats, respectively. [2]
Domestic dogs in Belgium showed a mean prevalence of T. canis of 4.4%, those from larger kennels of up to 31%. [6] In domestic dogs in Serbia, T. canis was detectable in 30% of the animals, [7] in herding and hunting dogs in Greece in 12.8% and T. leonina in 0.7% of animals. [8]
Thelazia callipaeda is a parasitic nematode, and the most common cause of thelaziasis (or eyeworm infestation) in humans, dogs and cats. [1] It was first discovered in the eyes of a dog in China in 1910. [2] By 2000, over 250 human cases had been reported in the medical literature. [3]
The parasite can cause canine schistosomiasis, an illness that affects the liver and intestines of dogs, according to Dillman. Read more: It hit 120 degrees in this California town. For the ...
Humans can contract this parasite in three main ways (ingestion of under cooked meat, contaminated water, or poultices contained contaminated flesh). [ 4 ] [ 5 ] Historically, humans are considered a paratenic host; however, the first case of an adult S. erinaceieuropaei infection in humans was reported in 2017.
The parasite reproduces inside the host and its eggs travel to the animal’s lungs, spleen, liver and heart. Dillman said raccoons are most susceptible to the parasite. Bobcats, mountain lions ...
