|
|
Term
|

Term
|
Definition
| "to carry" no physiologic dependency, one phoront is usually smaller and is MECHANICALLY carried. |
|
|
Term
|
Definition
| Both partners benefit. They depend on each other physiologically (Ex: termites will die if flagellate protozoans in gut not present to produce cellulase) |
|
|
Term
|
Definition
| "eating at the same table" commensal feeds on substances captured of ingested by host. No harm to host. |
|
|
Term
|
Definition
| parasite physiologically dependent on host. Usually harms, or lives at the expense of the host. |
|
|
Term
|
Definition
| Does not need to be symbiotic, but can. |
|
|
Term
|
Definition
| Is "obligated" to be a symbiotic creature. Cannot live without the host. |
|
|
Term
|
Definition
| live within the body of the host (internal=infection) |
|
|
Term
|
Definition
| attach to outer surface of the host or superficially embedded (external=infestation) |
|
|
Term
|
Definition
| live entire adult life in or on host (tapeworms, lice) |
|
|
Term
| Temporary or Intermittent Parasites |
|
Definition
| (micropredators) feeds on host then leaves (mosquitos, ticks) |
|
|
Term
|
Definition
| physiologically dependent on host, cannot complete life cycle without host, may have free-living stages |
|
|
Term
|
Definition
| free-living, but capable of becoming parasitic |
|
|
Term
| Accidental/incidental Parasites |
|
Definition
| enter or attach to host, usually do not survive, but may be very pathogenic. |
|
|
Term
|
Definition
| insects (wasps, flies) that feed on hosts during immature stages of development and kill host usually at completion of development |
|
|
Term
|
Definition
| organism is parasitic only during larval stages and free living as adults. |
|
|
Term
|
Definition
| parasite reaches sexual maturity or reproduction occurs |
|
|
Term
|
Definition
| required for development of parasite, sexual maturity not achieved. |
|
|
Term
| Paratenic or Transport Host |
|
Definition
| no development of parasite occurs, only larval stages present |
|
|
Term
|
Definition
| infectious organism is maintained in nature, infected animals serve as sources of infective organisms for humans |

Term
|
Definition
