Infestation of animals with parasitic worms of the helminth class. The infestation may be experimental or veterinary.

Broad spectrum antinematodal anthelmintic used also in veterinary medicine.

The treatment of immune system diseases by deliberate infestation with helminths. This therapy is partly based on the HYGIENE HYPOTHESIS which states that the absence of parasites increases immune dysregulation because of the lack of stimulation of REGULATORY T-CELLS.

Excrement from the INTESTINES, containing unabsorbed solids, waste products, secretions, and BACTERIA of the DIGESTIVE SYSTEM.

A genus of nematodes of the superfamily ASCARIDOIDEA whose species usually inhabit the intestine.

Inbred AKR mice are a strain of laboratory mice that are homozygous at all gene loci and have a high incidence of developing certain diseases, such as leukemia and autoimmune disorders, making them useful for research purposes in biomedicine.

The study of disease in prehistoric times as revealed in bones, mummies, and archaeologic artifacts.

Infection of humans or animals with hookworms of the genus ANCYLOSTOMA. Characteristics include anemia, dyspepsia, eosinophilia, and abdominal swelling.

Acute inflammation of the intestine associated with infectious DIARRHEA of various etiologies, generally acquired by eating contaminated food containing TOXINS, BIOLOGICAL derived from BACTERIA or other microorganisms. Dysentery is characterized initially by watery FECES then by bloody mucoid stools. It is often associated with ABDOMINAL PAIN; FEVER; and DEHYDRATION.

A genus of nematode intestinal parasites that consists of several species. A. duodenale is the common hookworm in humans. A. braziliense, A. ceylonicum, and A. caninum occur primarily in cats and dogs, but all have been known to occur in humans.

A class of unsegmented helminths with fundamental bilateral symmetry and secondary triradiate symmetry of the oral and esophageal structures. Many species are parasites.

Infections with unicellular organisms formerly members of the subkingdom Protozoa.

The persistent eating of nonnutritive substances for a period of at least one month. (DSM-IV)

A segment of the LOWER GASTROINTESTINAL TRACT that includes the CECUM; the COLON; and the RECTUM.

Infections or infestations with parasitic organisms. The infestation may be experimental or veterinary.

A genus of small tapeworms of birds and mammals.

A genus of nematodes of the superfamily STRONGYLOIDEA, parasitic in the intestines of animals. The adults are usually free in the intestinal lumen; the larvae encyst in the wall.

The unconsolidated mineral or organic matter on the surface of the earth that serves as a natural medium for the growth of land plants.

Infection of the intestinal tract with worms of the genus OESOPHAGOSTOMUM. This condition occurs mainly in animals other than man.

Immunoglobulins produced in a response to HELMINTH ANTIGENS.

A common parasite of humans in the moist tropics and subtropics. These organisms attach to villi in the small intestine and suck blood causing diarrhea, anorexia, and anemia.

Antinematodal benzimidazole used in veterinary medicine.

A species of baboon in the family CERCOPITHECIDAE, which has a well-studied trilevel social structure consisting of troops, bands, and clans.

A subfamily of the Old World monkeys, CERCOPITHECIDAE, that inhabits the forests of Africa and Asia. The genera COLOBUS (Procolobus; colobus), Nasalis (proboscis monkey), Presbytis (Semnopithecus; leaf monkey), Pygathrix (Rhinopithecus; snub-nosed monkey), and Simias (pig-tailed langur) all belong to this subfamily.

A subclass of segmented worms comprising the tapeworms.

A species of baboon in the family CERCOPITHECIDAE found in southern equatorial and east Africa. They are smaller than PAPIO ANUBIS and have a thinner mane.

Invertebrate organisms that live on or in another organism (the host), and benefit at the expense of the other. Traditionally excluded from definition of parasites are pathogenic BACTERIA; FUNGI; VIRUSES; and PLANTS; though they may live parasitically.

A mixture of mostly avermectin H2B1a (RN 71827-03-7) with some avermectin H2B1b (RN 70209-81-3), which are macrolides from STREPTOMYCES avermitilis. It binds glutamate-gated chloride channel to cause increased permeability and hyperpolarization of nerve and muscle cells. It also interacts with other CHLORIDE CHANNELS. It is a broad spectrum antiparasitic that is active against microfilariae of ONCHOCERCA VOLVULUS but not the adult form.

A genus of parasitic nematodes widely distributed as intestinal parasites of mammals.

I'm sorry for any confusion, but "Honduras" is a country located in Central America and it doesn't have a medical definition. If you have any questions related to medical topics or definitions, I'd be happy to help with those!

Infection with tapeworms of the genus Hymenolepis.

Infection with nematodes of the genus STRONGYLOIDES. The presence of larvae may produce pneumonitis and the presence of adult worms in the intestine could lead to moderate to severe diarrhea.

I'm sorry for any confusion, but "Ecuador" is a country in South America and not a medical term. The term you might be looking for is "ecdysone," which is a hormone found in arthropods that controls their molting process.

Infection of humans or animals with hookworms of the genus NECATOR. The resulting anemia from this condition is less severe than that from ANCYLOSTOMIASIS.

A glandular epithelial cell or a unicellular gland. Goblet cells secrete MUCUS. They are scattered in the epithelial linings of many organs, especially the SMALL INTESTINE and the RESPIRATORY TRACT.

The total number of cases of a given disease in a specified population at a designated time. It is differentiated from INCIDENCE, which refers to the number of new cases in the population at a given time.

A species of parasitic nematode widely distributed in tropical and subtropical countries. The females and their larvae inhabit the mucosa of the intestinal tract, where they cause ulceration and diarrhea.

Facilities provided for human excretion, often with accompanying handwashing facilities.

Infections or infestations with parasitic organisms. They are often contracted through contact with an intermediate vector, but may occur as the result of direct exposure.
