Not illustrated. 1869 Excerpt: ...nothing certain is understood respecting its true larval source. In the adult state it sometimes occurs in prodigious numbers, and often associated with other parasites. In one valuable animal, a pointer, which died suddenly, I found between 500 and 600 of these parasites, associated with numerous examples of three other kinds of Entozoa. In this particular instance, it appeared clear to me that Entozoa, alone, were the cause of the dog's death. If the canine tapeworm species, which are dangerous to human life, became as abundant in this country as the harmless Tcenia cucumerina has been shown to be, then our mortality would be increased by many thousands annually. This will, perhaps, be made more apparent in the sequel. 15. Tainia serrata.--Though by no means so abundant as the preceding, this parasite is nevertheless sufficiently common, whilst it is also more injurious to the bearer. Taking one variety of dog with another, I should say that it occurs in at least five per cent, of our English dogs; but in harriers and greyhounds I have little doubt that its presence is all but invariable. At Copenhagen Dr. Krabbe only encountered this parasite once; and in Iceland it seemed altogether wanting. The practice of giving the viscera of hares and rabbits to sporting dogs (which I have myself occasionally witnessed in the field) will always ensure the prevalence of this entozoon in our dogs. On five or six separate occasions I have reared this tapeworm in dogs by administration of the larva? (Cijsticercus pisiformis) taken from recently killed rabbits. It is one of the most easily reared of all the canine parasites; and, if due attention be paid to the form and size of the head and its conspicuous crown of hooks, cannot well be confounded with its allies. The ol...
