PATHOLOGY

Detailed explanation-1: -Fleas as intermediate hosts of parasites. Fleas play an important role as intermittent hosts in the development of at least three species of tapeworms. The double-pored tapeworm (Dipylidium caninum) is dependent on fleas as intermediate hosts and on dogs as final hosts.

Detailed explanation-2: -Stage 1: Flea eggs Female fleas usually lay on average 20 eggs per day but they can lay as many as 50. Flea eggs represent around half the entire flea population in the home.

Detailed explanation-3: -Parasitism. Some fleas (e.g., shrew fleas and rabbit fleas) are highly host-specific, whereas other species parasitize a variety of mammals. The cat flea infects not only the domestic cat but dogs, foxes, civets, mongooses, opossums, leopards, and other mammals, including humans, if its regular hosts are not available.
