Gravid proglottids may actively migrate from the animal’s anus or from fecal material and disintegrate, spreading tapeworm eggs in the environment. Larvae of dog and cat fleas (more rarely the dog louse and the human flea) ingest the eggs and act as intermediate hosts, with the tapeworm larvae maturing in the flea. When a dog or cat ingests an infected adult flea, the larvae are released, and the adult tapeworm develops in the animal’s small intestine about 1 month after infection. A single flea may contain multiple tapeworm larvae, and infection with more than 1 tapeworm is possible.1,2 SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/04/17 UR - accesspediatrics.mhmedical.com/content.aspx?aid=7031326 ER -
