A superfamily of nematodes of the suborder SPIRURINA. Its organisms possess a filiform body and a mouth surrounded by papillae.
Infection with nematodes of the genus Setaria. This condition is usually seen in cattle and equines and is of little pathogenic significance, although migration of the worm to the eye may lead to blindness.
A genus of parasitic nematodes found in the peritoneal cavity of wild or domestic cattle or equines.
The study of parasites and PARASITIC DISEASES.
A class of unsegmented helminths with fundamental bilateral symmetry and secondary triradiate symmetry of the oral and esophageal structures. Many species are parasites.
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.
Collection and analysis of data pertaining to operations of a particular library, library system, or group of independent libraries, with recommendations for improvement and/or ordered plans for further development.
A genus of deer, Rangifer, that inhabits the northern parts of Europe, Asia, and America. Caribou is the North American name; reindeer, the European. They are often domesticated and used, especially in Lapland, for drawing sleds and as a source of food. Rangifer is the only genus of the deer family in which both sexes are antlered. Most caribou inhabit arctic tundra and surrounding arboreal coniferous forests and most have seasonal shifts in migration. They are hunted extensively for their meat, skin, antlers, and other parts. (From Webster, 3d ed; Walker's Mammals of the World, 5th ed, p1397)
A plant genus of the family POACEAE. The small pointed seeds are grown for hay in North America and western Europe and important as food in China and other Asian countries.
A genus of mosquitoes (CULICIDAE) that are known vectors of MALARIA.
A genus of parasitic nematodes whose organisms live and breed in skin and subcutaneous tissues. Onchocercal microfilariae may also be found in the urine, blood, or sputum.
Works containing information articles on subjects in every field of knowledge, usually arranged in alphabetical order, or a similar work limited to a special field or subject. (From The ALA Glossary of Library and Information Science, 1983)
Several species of the genus Simulium (family Simuliidae) that act as intermediate hosts (vectors) for the parasitic disease ONCHOCERCIASIS.
Infection with nematodes of the genus MANSONELLA. Symptoms include pruritus, headache, and articular swelling.
A species of parasitic nematodes widely distributed throughout central Africa and also found in northern South America, southern Mexico, and Guatemala. Its intermediate host and vector is the blackfly or buffalo gnat.
Infection with nematodes of the genus ONCHOCERCA. Characteristics include the presence of firm subcutaneous nodules filled with adult worms, PRURITUS, and ocular lesions.
A genus of parasitic nematodes whose organisms are distributed in Central and South America. Characteristics include a smooth cuticle and an enlarged anterior end.
The largest genus of TICKS in the family IXODIDAE, containing over 200 species. Many infest humans and other mammals and several are vectors of diseases such as LYME DISEASE, tick-borne encephalitis (ENCEPHALITIS, TICK-BORNE), and KYASANUR FOREST DISEASE.
Blood-sucking acarid parasites of the order Ixodida comprising two families: the softbacked ticks (ARGASIDAE) and hardbacked ticks (IXODIDAE). Ticks are larger than their relatives, the MITES. They penetrate the skin of their host by means of highly specialized, hooked mouth parts and feed on its blood. Ticks attack all groups of terrestrial vertebrates. In humans they are responsible for many TICK-BORNE DISEASES, including the transmission of ROCKY MOUNTAIN SPOTTED FEVER; TULAREMIA; BABESIOSIS; AFRICAN SWINE FEVER; and RELAPSING FEVER. (From Barnes, Invertebrate Zoology, 5th ed, pp543-44)
A family of hardbacked TICKS, in the subclass ACARI. Genera include DERMACENTOR and IXODES among others.
A filarial nematode parasite of mammalian blood with the vector being a tick or small fly.
Infestations with soft-bodied (Argasidae) or hard-bodied (Ixodidae) ticks.
The immature stage in the life cycle of those orders of insects characterized by gradual metamorphosis, in which the young resemble the imago in general form of body, including compound eyes and external wings; also the 8-legged stage of mites and ticks that follows the first moult.
Regulations to assure protection of property and equipment.
Monitoring of information sources of potential value in detecting an emerging epidemic, whether naturally occurring or the result of bioterrorism.
The interaction of persons or groups of persons representing various nations in the pursuit of a common goal or interest.
Living organisms or their toxic products that are used to cause disease or death of humans during WARFARE.
Warfare involving the use of living organisms or their products as disease etiologic agents against people, animals, or plants.
The use of biological agents in TERRORISM. This includes the malevolent use of BACTERIA; VIRUSES; or other BIOLOGICAL TOXINS against people, ANIMALS; or PLANTS.
A multistage process that includes cloning, physical mapping, subcloning, determination of the DNA SEQUENCE, and information analysis.
