The eggs hatch in the intestine and young larvae are then excreted in the feces. Living outdoors and sleeping on straw bedding were common factors in all of our Finnish Hounds. In the case of Strongyloides, autoinfection may explain the possibility of persistent infections for many years in persons not having been in an endemic area and of hyperinfections in immunodepressed individuals. Thus it is possible that one or more individuals in a group of animals sharing some element(s) of an environment may show similar clinical signs. Both sexes also possess a tiny buccal capsule and cylindrical esophagus without a posterior bulb. Georgi JR, Georgi ME: Rhabditis (Pelodera).
