Huacaya Alpaca
The Huacaya alpaca is a breed of alpaca (''Lama pacos'') that has a unique appearance and fiber quality. This breed is the most popular alpaca breed with population numbers reaching 2.8 million in Peru alone. They share biological components with other species in the Camelidae family. Their digestive tract, nutrition requirements, and herd behavior mirror that of all camelids. They also survive amidst similar predation, poison, and disease threats that endanger all camelids alike. Breed The Huacaya alpaca is one of two breeds of alpaca, the other breed being the Suri alpaca. Both breeds were first domesticated by the Incas thousands of years ago from a wild species of camelid, the vicuña. The native homeland of the Huacaya is the Andean highlands of South America, called the Altiplano. It is above sea level and reaches into Peru, Chile, and Bolivia. * An edited version also published as: In the 1980s, these Huacaya were imported to other countries including Australia, Canad ...

Alpaca
The alpaca (''Lama pacos'') is a species of South American camelid mammal. Traditionally, alpacas were kept in herds that grazed on the level heights of the Andes of Southern Peru, Western Bolivia, Ecuador, and Northern Chile. More recently, alpacas may be found on farms and ranches worldwide, with thousands of animals born and raised annually. Alpacas are especially popular in North America, Europe, and Australia. There are two modern breeds of alpaca, separated based on their respective region of endemism and fiber (wool) type: the Suri alpaca and the Huacaya alpaca. Both breeds produce a highly valued fiber, with Suri alpaca's fiber growing in straight "locks," while Huacaya fiber has a "crimped," wavy texture and grows in bundles. These breeds' fibers are used for making knitted and woven items, similar to sheep's wool. Alpacas are visually and genetically similar to, and often confused with a relative species, the llamas; however, alpacas are visibly shorter and pr ...

Rhododendron
''Rhododendron'' (; : ''rhododendra'') is a very large genus of about 1,024 species of woody plants in the Ericaceae, heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia. It is the national flower of Nepal, the List of U.S. state and territory flowers, state flower of Washington (state), Washington and West Virginia in the United States, the state flower of Nagaland and Himachal Pradesh in India, the provincial flower of Jeju Province in South Korea, the provincial flower of Jiangxi in China and the List of Indian state trees, state tree of Sikkim and Uttarakhand in India. Most species have brightly coloured flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of ''Rhododendron''. They are distinguished from "true" rhododendrons by having only five anthers per flower. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Brucellosis
Brucellosis is a zoonosis spread primarily via ingestion of raw milk, unpasteurized milk from infected animals. It is also known as undulant fever, Malta fever, and Mediterranean fever. The bacteria causing this disease, ''Brucella'', are small, Gram-negative, nonmotile, nonspore-forming, rod-shaped (Coccobacillus, coccobacilli) bacteria. They function as Facultative parasite, facultative intracellular parasites, causing Chronic (medicine), chronic disease, which usually persists for life. Four species infect humans: ''B. abortus'', ''B. canis'', ''B. melitensis'', and ''B. suis''. ''B. abortus'' is less virulent than ''B. melitensis'' and is primarily a disease of cattle. ''B. canis'' affects dogs. ''B. melitensis'' is the most virulent and invasive species; it usually infects goats and occasionally sheep. ''B. suis'' is of intermediate virulence and chiefly infects pigs. Symptoms include Diaphoresis, profuse sweating and Arthralgia, joint and Myalgia, muscle pain. Brucellosis h ...

Anthrax
Anthrax is an infection caused by the bacterium '' Bacillus anthracis'' or ''Bacillus cereus'' biovar ''anthracis''. Infection typically occurs by contact with the skin, inhalation, or intestinal absorption. Symptom onset occurs between one day and more than two months after the infection is contracted. The skin form presents with a small blister with surrounding swelling that often turns into a painless ulcer with a black center. The inhalation form presents with fever, chest pain, and shortness of breath. The intestinal form presents with diarrhea (which may contain blood), abdominal pains, nausea, and vomiting. According to the U.S. Centers for Disease Control and Prevention, the first clinical descriptions of cutaneous anthrax were given by Maret in 1752 and Fournier in 1769. Before that, anthrax had been described only in historical accounts. The German scientist Robert Koch was the first to identify ''Bacillus anthracis'' as the bacterium that causes anthrax. Anthra ...

Botfly
Botflies, also known as warble flies, heel flies, and gadflies, are flies of the family Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. '' Dermatobia hominis'' is the only species of botfly known to parasitize humans routinely, though other species of flies cause myiasis in humans. General A botfly, also written bot fly, bott fly or bot-fly in various combinations, is any fly in the family Oestridae. Their life cycles vary greatly according to species, but the larvae of all species are internal parasites of mammals. Largely according to species, they also are known variously as warble flies, heel flies, and gadflies. The larvae of some species grow in the flesh of their hosts, while others grow within the hosts' alimentary tracts. The word "bot" in this sense means a maggot. A warble is a skin lump or callus such as might be caused by an ill-fitting harness, or by the presence of a warble fly m ...

Coccidia
Coccidia (Coccidiasina) are a subclass of microscopic, spore-forming, single-celled obligate intracellular parasites belonging to the apicomplexan class Conoidasida. As obligate intracellular parasites, they must live and reproduce within an animal cell. Coccidian parasites infect the intestinal tracts of animals, and are the largest group of apicomplexan protozoa. Infection with these parasites is known as coccidiosis. Coccidia can infect all mammals, some birds, some fish, some reptiles, and some amphibians. Most species of coccidia are species-specific in their host. An exception is '' Toxoplasma gondii'', which can infect all mammals, although it can only undergo sexual reproduction in cats. Depending on the species of coccidia, infection can cause fever, vomiting, diarrhea, muscle pain, and nervous system effects and changes to behavior, and may lead to death. Healthy adults may recover without medication—but those who are immunocompromised or young almost certainly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Liver Fluke
Liver fluke is a collective name of a polyphyletic group of parasitic trematodes under the phylum Platyhelminthes. They are principally parasites of the liver of various mammals, including humans. Capable of moving along the blood circulation, they can occur also in bile ducts, gallbladder, and liver parenchyma. In these organs, they produce pathological lesions leading to parasitic diseases. They have complex life cycles requiring two or three different hosts, with free-living larval stages in water. Biology The body of liver flukes is leaf-like and flattened. The body is covered with a tegument. They are hermaphrodites having complete sets of both male and female reproductive systems. They have simple digestive systems and primarily feed on blood. The anterior end has the oral sucker opening into the mouth. Inside, the mouth leads to a small pharynx which is followed by an extended intestine that runs the entire length of the body. The intestine is heavily branched and t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tapeworm
Eucestoda, commonly referred to as tapeworms, is the larger of the two subclasses of flatworms in the class Cestoda (the other subclass being Cestodaria). Larvae have six posterior hooks on the scolex (head), in contrast to the ten-hooked Cestodaria. All tapeworms are endoparasites of vertebrates, living in the digestive tract or related ducts. Examples are the pork tapeworm (''Taenia solium'') with a human definitive host, and pigs as the secondary host, and '' Moniezia expansa'', the definitive hosts of which are ruminants. Body structure Adult Eucestoda have a white-opaque dorso-ventrally flattened appearance, and are elongated, ranging in length from a few millimeters (about ¼") to 25 meters (80'). Almost all members, except members of the orders Caryophyllidea and Spathebothriidea, are polyzoic with repeated sets of reproductive organs down the body length, and almost all members, except members of the order Dioecocestidae, are protandral hermaphrodites. Most exce ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lungworms
Lungworms are parasite, parasitic nematode worms of the order Strongylida that infest the lungs of vertebrates. The name is used for a variety of different groups of nematodes, some of which also have other common names; what they have in common is that they migrate to their hosts' lungs or respiratory tracts, and cause bronchitis or pneumonia. The lungworm will gradually damage the airways or lung tissue by inciting an inflammatory reaction inside the tissue. Ultimately, the parasites survive and reproduce in the respiratory tissues. The category is thus more a descriptive than a precisely taxonomic one. The most common lungworms belong to one of two groups, the superfamily Trichostrongyloidea or the superfamily Metastrongyloidea, but not all the species in these superfamilies are lungworms. The lungworms in the superfamily Trichostrongyloidea include several species in the genus ''Dictyocaulus'' which infest hoofed animals, including most common domestic species. Different ...

Death Camas
Deathcamas or death camas refers to several species of flowering plant in the tribe Melanthieae. The name alludes to the great similarity of appearance between these toxic plants, which were formerly classified together in the genus ''Zigadenus'', and the edible camases (''Camassia''), with which they also often share habitat. Other common names for these plants include deadly zigadene, hog potato and mystery-grass. *''Anticlea elegans'' – Mountain deathcamas *''Anticlea mogollonensis'' – Mogollon deathcamas *''Anticlea vaginata'' – Sheathed deathcamas *''Anticlea virescens'' – Green deathcamas *''Anticlea volcanica'' – Lava deathcamas *''Stenanthium densum'' – Pinebarren deathcamas *''Toxicoscordion brevibracteatum'' – Desert deathcamas *''Toxicoscordion exaltatum'' – Giant deathcamas *''Toxicoscordion fontanum'' – Smallflower deathcamas *''Toxicoscordion fremontii'' – Fremont's deathcamas, star zigadene - (several varieties) *''Toxicoscordion micranthum'' – ...

Cocklebur
''Xanthium'' (cocklebur) is a genus of flowering plants in the tribe Heliantheae within the family Asteraceae, native to the Americas and eastern Asia and some parts of south Asia. Description Cockleburs are coarse, herbaceous annual plants growing to tall. The leaves are spirally arranged, with deeply toothed margins. Some species, notably '' Xanthium spinosum'', are also very thorny with long, slender spines at the leaf bases. The flower heads are of two types; One, in short terminal branches, produces only pollen. The other, in clusters in the axils of the leaves, produces seed. Unlike many other members of the family Asteraceae, whose seeds are airborne with a plume of silky hairs resembling miniature parachutes, cocklebur seeds are produced in a hard, spiny, globose or oval double-chambered, single-seeded bur long. It is covered with stiff, hooked spines, which stick to fur and clothing and can be quite difficult to detach. These burs are carried long distances from th ...

Bracken Fern
Bracken (''Pteridium'') is a genus of large, coarse ferns in the family Dennstaedtiaceae. Ferns (Pteridophyta) are vascular plants that undergo alternation of generations, having both large plants that produce spores and small plants that produce sex cells (eggs and sperm) in its life cycle. Brackens are noted for their large, highly divided leaves. They are found on all continents except Antarctica and in all environments except deserts, though their typical habitat is moorland. The genus probably has the widest distribution of any fern in the world. The word ''bracken'' is of Old Norse origin, related to Swedish ''bräken'' and Danish ''bregne'', both meaning fern. In the past, the genus was commonly treated as having only one species, ''Pteridium aquilinum'', but the recent trend is to subdivide it into about ten species. Like other ferns, brackens do not have seeds or fruit, but reproduce by spores. The immature fronds, known as ''fiddleheads'', are sometimes eaten, althoug ...
