|
Term
|
Definition
| The time taken for development from infection until mature adult parasites are producing eggs or larvae. |
|
|
Term
|
Definition
| The parasite makes itself sexually immature within the host until more favorable conditions are reached; usually seen as a seasonal arrest. Improves the chances for the progeny. |
|
|
Term
|
Definition
| When an animal has a higher serum prolactin level during pregnancy, parasitic immunity decreases. Therefore, larger numbers of eggs are found in the feces. |
|
|
Term
| Definitive Host; Final Host |
|
Definition
| The host in which sexual reproduction of the adult parasites will take place (production of offspring). |
|
|
Term
|
Definition
| "Biological Vector"; a temporary host that provides partial development of the parasite. Still needs another host to achieve maturity. Required for completion of lifecycle. |
|
|
Term
|
Definition
| A temporary host that keeps the immature from of the parasite alive- no development occurs within this host. |
|
|
Term
|
Definition
| Stage of development in which the parasite can infect the host. |
|
|
Term
| Predilection Site (adult) |
|
Definition
| The location within a definitive host's body where the adult parasites will live. |
|
|
Term
|
Definition
| Location within a host's body where immature forms of the parasite may migrate or develop. |
|
|
Term
|
Definition
| A living creature that physically transports something potentially infective from point A to point B. Example- a fly landing on feces, then landing on a sandwich. |
|
|
Term
|
Definition
| "Opportunistic"; When an organism (arthropod) takes advantage of an opportunity that arises, but does not require it to complete its life cycle. |
|
|
Term
|
Definition
| "Required"; When an organism (arthropod) must use a specific host animal for the completion of a portion of its life cycle. |
|
|
Term
|
Definition
| Rotating grazing animals off of land known to be infested with an organism that cannot live in winter, and moving the herd back in the spring (for example). |
|
|
Term
|
Definition
| Parasite control within multiple herds of different species, when the definitive hosts cannot share the same parasites. Switching pastures infested with parasites keeps land from not being used and going to waste. |
|
|
Term
|
Definition
| Dewormer. Given to a host animal to rid it of a parasite. |
|
|
Term
|
Definition
| An organism that lives on or in an organism of another species from the body of which it obtains nutrients. |
|
|
Term
|
Definition
| Any of various parasitic flatworms of the class Cestoda, including the tapeworms, having a long flat body equipped with a specialized organ of attachment at one end. |
|
|
Term
|
Definition
| Newly hatched, wormlike, free-living, immature form of an organism, before it turns into an adult. |
|
|
Term
|
Definition
| A chemical preparation designed to destroy plant, animal, and fungal pests. |
|
|
Term
|
Definition
| Any animal of the class Insecta, comprising small, air-breathing arthropods having the body divided into three parts (head, thorax, and abdomen), and having three pairs of legs and usually two pairs of wings. |
|
|
Term
|
Definition
| The immature form of those insects that do not pass through a pupal stage. They usually resemble the adults, but are smaller, lack fully developed wings, and are sexually immature. |
|
|
Term
|
Definition
| Any of several worms of the phylum Nematoda, having unsegmented, cylindrical bodies, often narrowing at each end, and including parasitic forms such as the hookworm and pinworm. Also called roundworms. |
|

Term
|
Definition
| a hard flap serving as a cover for (a) the gill slits in fishes or (b) the opening of the shell in certain gastropods when the body is retracted |
|
|
Term
|
Definition
| A worm, especially a parasitic roundworm or tapeworm. |
|
|
Term
|
Definition
| The nonfeeding stage between the larva and adult in the metamorphosis of insects, during which the larva typically undergoes complete transformation within a protective cocoon or hardened case. |
|
|
Term
|
Definition
| the marked and rapid transformation of a larva into an adult that occurs in some animals |
|
|
Term
|
Definition
| any wingless, carnivorous arthropod of the class Arachnida, including spiders, scorpions, mites, ticks, and daddy-longlegs, having a body divided into two parts, the cephalothorax and the abdomen, and having eight appendages and no antennae. |
|
|
Term
|
Definition
| any invertebrate of the phylum Arthropoda, having a segmented body, jointed limbs, and usually a chitinous shell that undergoes moltings, including the insects, spiders and other arachnids, crustaceans, and myriapods. |
|
|
Term
|
Definition
| Any of numerous flatworms of the class Trematoda, including both external and internal parasites of animal hosts, that have a thick outer cuticle and one or more suckers or hooks for attaching to host tissue. |
|
|
Term
|
Definition
| any of a diverse group of eukaryotes, of the kingdom Protista, that are primarily unicellular, existing singly or aggregating into colonies, are usually nonphotosynthetic, and are often classified further into phyla according to their capacity for and means of motility, as by pseudopods, flagella, or cilia. |
|
|
Term
|
Definition
| an insect in any one of its periods of postembryonic growth between molts. |

Term
|
Definition
| A condition marked by black, tarry stool or vomit composed largely of blood that has been acted on by gastric juices, resulting from a hemorrhage along the digestive tract. |

Definition
| A skin disease of horses caused in part by the larvae of stomach worms. When the larvae emerge from flies feeding on preexisting wounds or on moisture of the genitalia or eyes, they migrate into and irritate the tissue, which causes a granulomatous reaction. |
