However, it seems unlikely that marine mammals would have the opportunity to ingest such fish with any frequency. Transmission to humans occurs when eggs of the tapeworm, excreted by the final hosts (usually foxes but also dogs, wolves and cats), are ingested accidentally. During inoculation care was taken to ensure that all the metacercariae were ingested by the experimental animals. After parasite eggs are accidentally ingested by grazing snails, they develop within the snail and multiply asexually into cercariae. Humans become infected by ingesting embryonated eggs from soil or contaminated food. However, it is widely held that when ingested with food the infectious dose may be reduced by at least 1000-fold. In a second case, liquid gelatin was employed which was also ingested though less readily than the previous liquid. To complete the life cycle metacercariae must be ingested by definitive hosts. If the parasites encyst in the open, they will be accidentally ingested by the definitive host, usually a grazing mammal of some sort. The gammarids are orally infected when ingesting parasite eggs released in the faeces of the definitive host. Finally, encysted metacercariae within the second intermediate host must be ingested by a suitable vertebrate definitive host for the parasite to become an egg-producing adult. The seeds of at least six species were ingested whole and defecated intact. After ingesting the cysticerci, the human volunteers checked their faeces daily for the presence of proglottids. Thus iron, ingested by hookworms, even if excreted again cannot be re-absorbed and is therefore lost. The few avian frugivores that forage on the ground leave obvious marks (catbird, tooth-billed bowerbird) or ingest fruit whole (cassowary). Only when the oocyst is ingested and passes through the mammalian gut does destabilization of the wall occur with the opening of the suture. Stricture formation is frequent after ingesting caustic chemicals such as strong acids or alkalis. Some microbes found on the forest floor can cause disease or in extreme cases death if ingested. In spring, the numbers of eggs can increase suddenly even though no larvae have been ingested for months. One means "to ingest crunchy-solid foods" (like carrots). When ingested by an intermediate host, the oncosphere hatches in the gut. The organisms apparently are ingested with the food. These examples are from corpora and from sources on the web.
