What kind of helminths can cats transmit to humans? - briefly
Cats can transmit helminths such as Toxocara cati (roundworms) and Dipylidium caninum (tapeworms) to humans, primarily through contact with contaminated feces or fleas.
What kind of helminths can cats transmit to humans? - in detail
Cats can transmit several types of helminths, or parasitic worms, to humans, posing potential health risks. One of the most common helminths is Toxocara cati, a roundworm found in cats. Humans, particularly children, can become infected by accidentally ingesting eggs from contaminated soil, sand, or surfaces. This can lead to toxocariasis, a condition that may cause visceral larva migrans, where larvae migrate through organs, or ocular larva migrans, affecting the eyes. Another helminth is Ancylostoma braziliense, a hookworm species. Humans can contract cutaneous larva migrans, also known as "creeping eruption," when larvae penetrate the skin, typically through contact with contaminated soil. This results in itchy, serpentine skin lesions. Cats can also carry Dipylidium caninum, a tapeworm transmitted to humans through accidental ingestion of infected fleas. While rare, this can lead to mild gastrointestinal symptoms. Additionally, cats may harbor Echinococcus species, particularly Echinococcus multilocularis, which can cause alveolar echinococcosis in humans. This is a severe condition where cysts form in the liver and other organs, potentially leading to life-threatening complications. Proper hygiene, regular deworming of cats, and avoiding contact with contaminated environments are essential preventive measures to reduce the risk of zoonotic helminth infections.
