Taeniatype eggs – both Taenia and Echinococcus species have “taenia- type”eggs. To differentiate the likelihood of the animal being infected with thedifferent species, we can ask the owner about the diet and the environment ofthe animal.The eggs are very small, 30-55μm, with a thick smooth shell, they are and contain a6-hooked oncosphere (L1). Their shape is slightly elongated ovoid (almostround). They are passed out with the faeces of the infected animal
