So, it can create hydatid cyst in human liver. But, the the the main host is is dog in this case. Okay, Echinococcus granulosus.

[00:00:30]So, what happens is accidentally it can infect hosts, the host that are are not the typical host, right? That are not the part of of its its regular life cycle.

[00:00:45]So, it's going to infect a host which is not the natural host, and then it can cause infection over there. Example is Echinococcus Echinococcus granulosus.
