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] Humans are among the many "accidental" or paratenic hosts of these roundworms. [3]
Toxocara cati, also known as the feline roundworm, is a parasite of cats and other felids. It is one of the most common nematodes of cats, infecting both wild and domestic felids worldwide. Adult worms are localised in the gut of the host. In adult cats, the infection – which is called toxocariasis – is usually asymptomatic. However ...
The Toxocaridae are a zoonotic family of parasitic nematodes that infect canids and felids and which cause toxocariasis in humans (visceral larva migrans and ocular larva migrans). [1] The worms are unable to reproduce in humans. Notable species include: Toxocara canis, which infects dogs. Toxocara cati, which infects cats and lacks ...
Ocular larva migrans (OLM), also known as ocular toxocariasis, is the ocular form of larva migrans syndrome.It occurs when roundworm larvae invade the human eye. OLM infections in humans are caused by the larvae of Toxocara canis (dog roundworm), Toxocara cati (feline roundworm), Ascaris suum (large roundworm of pig), or Baylisascaris procyonis (raccoon roundworm).
Roundworms and a cucumber nematode tapeworm in the vomit of a cat Kitten with high grade roundworm infestation. In principle, roundworms do not require intermediate hosts. Nevertheless, infection via transport hosts such as rodents is the most common route of infection in adult cats. The larvae migrate in the transport host through the ...
What they look like: Another too-close-for-comfort pest are head lice, which leave patches of red, abraded spots on the scalp and surrounding skin (like this one pictured). Although their bites ...
Ascariasis is a disease caused by the parasitic roundworm Ascaris lumbricoides. [1] Infections have no symptoms in more than 85% of cases, especially if the number of worms is small. [1] Symptoms increase with the number of worms present and may include shortness of breath and fever at the beginning of the disease. [1]

Children's physical and cognitive growth may be affected. [10] [11] [12] Dogs and cats may experience dermatitis, enteritis, and intestinal blood loss.
