HOSTS 



Domestic cattle and goats are the most common hosts of H. 

 truncatum but other large wild or domestic mammals may be iru 

 fested. Wild carnivores are seldom recorded as hosts. Rarely, 

 small mammals, birds, or tortoises are also attacked. Immature 

 stages are definitely knovm from birds and hares but most 

 published remarks concerning these stages should be accepted 

 with reservation because of questionable identity.
