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.

A genus of intestinal parasite worms which includes one of the most important hookworms of man, NECATOR AMERICANUS. The only other known species, N. suillus, has been recovered from pigs.

A gram-negative, facultatively chemoautotrophic bacterium, formerly called Wautersia eutropha, found in water and soil.

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

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

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 plant genus in the family VITACEAE, order Rhamnales, subclass Rosidae. It is a woody vine cultivated worldwide. It is best known for grapes, the edible fruit and used to make WINE and raisins.

A phylum of fungi which have cross-walls or septa in the mycelium. The perfect state is characterized by the formation of a saclike cell (ascus) containing ascospores. Most pathogenic fungi with a known perfect state belong to this phylum.

A superfamily of nematode parasitic hookworms consisting of four genera: ANCYLOSTOMA; NECATOR; Bunostomum; and Uncinaria. ANCYLOSTOMA and NECATOR occur in humans and other mammals. Bunostomum is common in ruminants and Uncinaria in wolves, foxes, and dogs.

Infection of humans or animals with hookworms other than those caused by the genus Ancylostoma or Necator, for which the specific terms ANCYLOSTOMIASIS and NECATORIASIS are available.

Benzoic acid or benzoic acid esters substituted with one or more chlorine atoms.

An order of flagellate protozoa. Characteristics include the presence of one or two flagella arising from a depression in the cell body and a single mitochondrion that extends the length of the body.

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

Phenols substituted with one or more chlorine atoms in any position.

An herbicide with irritant effects on the eye and the gastrointestinal system.

A republic in western Africa, lying between GHANA on its west and BENIN on its east. Its capital is Lome.

A species of parasitic nematode that is the largest found in the human intestine. Its distribution is worldwide, but it is more prevalent in areas of poor sanitation. Human infection with A. lumbricoides is acquired by swallowing fully embryonated eggs from contaminated soil.

A colorless, syrupy, strongly acidic liquid that can form detergents with oleic acid.

Infections with unicellular organisms formerly members of the subkingdom Protozoa. The infections may be experimental or veterinary.

Diseases of plants.

A genus of gram-negative, aerobic, rod-shaped bacteria, in the family BURKHOLDERIACEAE, that are mobile by means of peritrichous FLAGELLA. The genus was formerly called Wautersia and species in this genus were formerly in the genus RALSTONIA.

Infection by nematodes of the genus ASCARIS. Ingestion of infective eggs causes diarrhea and pneumonitis. Its distribution is more prevalent in areas of poor sanitation and where human feces are used for fertilizer.

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.

A family of gram negative, aerobic, non-sporeforming, rod-shaped bacteria.

Commonly known as parasitic worms, this group includes the ACANTHOCEPHALA; NEMATODA; and PLATYHELMINTHS. Some authors consider certain species of LEECHES that can become temporarily parasitic as helminths.

Any part or derivative of a helminth that elicits an immune reaction. The most commonly seen helminth antigens are those of the schistosomes.

A species of gram-negative rod-shaped bacteria found ubiquitously and formerly called Comamonas acidovorans and Pseudomonas acidovorans. It is the type species of the genus DELFTIA.

Deoxyribonucleic acid that makes up the genetic material of helminths.

Determination of parasite eggs in feces.

A genus of nematode worms comprising the whipworms.

Agents destructive to parasitic worms. They are used therapeutically in the treatment of HELMINTHIASIS in man and animal.

The body of a fungus which is made up of HYPHAE.

Elimination of ENVIRONMENTAL POLLUTANTS; PESTICIDES and other waste using living organisms, usually involving intervention of environmental or sanitation engineers.

Infections of the INTESTINES with PARASITES, commonly involving PARASITIC WORMS. Infections with roundworms (NEMATODE INFECTIONS) and tapeworms (CESTODE INFECTIONS) are also known as HELMINTHIASIS.

Polymers of organic acids and alcohols, with ester linkages--usually polyethylene terephthalate; can be cured into hard plastic, films or tapes, or fibers which can be woven into fabrics, meshes or velours.

Proteins found in any species of helminth.

Any of the DNA in between gene-coding DNA, including untranslated regions, 5' and 3' flanking regions, INTRONS, non-functional pseudogenes, and non-functional repetitive sequences. This DNA may or may not encode regulatory functions.

A multistage process that includes cloning, physical mapping, subcloning, determination of the DNA SEQUENCE, and information analysis.

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