Zoonoses can be defined by the group of diseases that can be transmitted between vertebrate and human animals naturally.

These diseases can be transmitted directly, by contact with secretions, or indirectly, as per consumption of certain contaminated products. The definition of zoonosis comes from two Greek words, “zoological” meaning animal and “nose” meaning disease.

Hydythidosis produces a hydatic cyst. This cyst can appear in any organ, mainly in the liver, lungs, etc., and can reach sizes greater than an orange.
This disease is complex because for its full development it requires two different subjects or hosts. The first host is the one that transports the worm, whose eggs expand with the animal’s faeces (usually a dog). These faeces contaminate plants that eat herbivores and tapeworm eggs grow in the duodenum of the new host (usually sheep). From there, they pass into the bloodstream and attach to an organ, where the larva creates the dangerous cyst, which can be fatal.
Humans, in many cases, contract this disease by eating lettuce or any other vegetables that are eaten raw and poorly washed.
