Which zoonotic disease can pets transmit to humans through parasites?

Toxocariasis is a zoonotic disease caused by the roundworms Toxocara canis or Toxocara cati, which are commonly found in dogs and cats. Humans can become infected by accidentally ingesting the eggs of these parasites, often through contaminated soil, hands, or food. This disease is of particular concern in children, who may be more likely to come into contact with contaminated environments.

Transmission typically occurs when the larvae from the ingested eggs migrate through the human body, which can lead to various health problems, particularly affecting the eyes and potentially causing vision loss. Because of its direct connection to pet roundworms and the common routes of transmission, Toxocariasis stands out as a prime example of a zoonotic disease transmitted through parasites from pets to humans.

Other listed options, while they involve various pathogens, do not fit the definition of zoonotic diseases transmitted through parasites in the context of typical domestic pets. For instance, Ringuletis is not a recognized zoonotic disease, Acanthamoebiasis is primarily associated with contaminated water and contact lens use rather than pet transmission, and Brucellosis, while zoonotic, is typically associated with livestock rather than companion animals like dogs and cats.
