Примеры ingest

• 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).
