Cats do not play a role in the spread of trichinosis because trichinae are rare in them and cats are not normally eaten by humans. The cat liver fluke can rarely cause disease in children if they swallow infected fleas, usually accidentally (→ dipylidiasis). Here, humans, like cats, act as the final host; direct infection from a cat is not ...
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 ...
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]
The majority of heartworm larvae do not survive in cats, so unlike in dogs, a typical infection in cats is two to five worms. The lifespan of heartworms is considerably shorter in cats, only two to three years, and most infections in cats do not have circulating microfilariae. Cats are also more likely to have aberrant migration of heartworm ...
A 2012 survey of 445 purebred pet cats and 45 shelter cats in Finland found an overall seroprevalence of 48.4%, [137] while a 2010 survey of feral cats from Giza, Egypt found a seroprevalence rate of 97.4%. [138] Another survey from Colombia recorded seroprevalence of 89.3%, [139] whereas a Chinese study found just a 2.1% prevalence. [140]
An exception is Toxoplasma gondii, which can infect all mammals, although it can only undergo sexual reproduction in cats. Depending on the species of coccidia, infection can cause fever, vomiting, diarrhea, muscle pain, and nervous system effects and changes to behavior, and may lead to death.
The significance of this approach is that, if the white blood cells in the small intestine have been exposed to Trichinella antigens (through vaccination) when an individual does get infected, the immune system will respond to expel the worms from the small intestine fast enough to prevent the female worms from releasing their larvae.
Once the cat ingests the infected eggs, they hatch and the larvae mature as adults in the large intestine, where they feed on the blood from the intestinal wall. T. campanula lays eggs that are passed in the feces of the infected cat, remaining alive in soil for years. The infection can be found by examining the feces of the infected cat.
