Hookworm
Hookworms are intestinal, blood-feeding, parasitic roundworms that cause types of infection known as helminthiases. Hookworm infection is found in many parts of the world, and is common in areas with poor access to adequate water, sanitation, and hygiene. In humans, infections are caused by two main species of roundworm, belonging to the genera ''Ancylostoma'' and '' Necator''. In other animals the main parasites are species of ''Ancylostoma''. Species The two most common types of hookworm that infect humans are ''Ancylostoma duodenale'' and ''Necator americanus''. Hookworm species that are known to infect domestic cats are ''Ancylostoma braziliense'' and ''Ancylostoma tubaeforme''. Wild cats are infected by ''Ancylostoma pluridentatum''. Dogs are commonly infected by ''Ancylostoma caninum'', but may also be infected by ''Uncinaria stenocephala'' and ''Ancylostoma braziliense''. In Asia, ''Ancylostoma ceylanicum'' is endemic among dogs and cats and infects humans. Cattle ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Angelo Dubini
Angelo Dubini (8 December 1813 – 28 March 1902) was an Italian physician born in Milan. He earned his doctorate from the University of Pavia in 1837 and spent most of his professional career at the ''Ospedale Maggiore'' in Milan. In 1865 he became head physician and director of the hospital's dermatology department. Dubini is remembered for his discovery of an intestinal parasite he named '' Anchylostoma duodenale''. He first noticed the parasite in 1838 during an autopsy of a peasant woman who died of croupous pneumonia. He would rediscover the parasite in the course of other autopsies in ensuing years. In 1843 he published his findings in ''Annali universali di medicina''. The pathogenicity of the parasite was eventually confirmed by way of research of Egyptian chlorosis conducted by Wilhelm Griesinger, Theodor Maximilian Bilharz and Franz Ignaz Pruner, as well as in Otto Eduard Heinrich Wucherer's study of tropical chlorosis (which would probably be called iron deficie ...

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancylostoma Braziliense
''Ancylostoma braziliense'' is a species of hookworm belonging to the genus ''Ancylostoma''. It is an intestinal parasite of domestic cats and dogs. Severe infection is often fatal to these pets, especially in puppies and kittens. The infection is particularly endemic in the southern United States. It is most often confused with the zoonotic hookworm species '' Ancylostoma ceylanicum'' because of their uncanny resemblance. ''Ancyclostoma braziliense'' larvae can cause accidental infection in humans called cutaneous larval migration or creeping eruption, which produces severe itching in the skin. It is the most common skin infection in tropical region, particularly along the beaches of the Caribbean. Discovery and history When ''A. braziliense'' was described by Gomes de Faria in 1910, and ''A. ceylanicum'' by Arthur Looss in 1911, the two species were regarded as synonymous because of their apparent similarities in almost all respect. Especially in 1913, comparison of specimen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancylostoma Caninum
''Ancylostoma caninum'' is a species of nematode known as a hookworm, which principally infects the small intestine of dogs. The result of ''A. caninum'' infection ranges from asymptomatic cases to death of the dog; better nourishment, increasing age, prior ''A. caninum'' exposure, or vaccination are all linked to improved survival. Other hosts include carnivores such as wolves, foxes, and cats, with a small number of cases having been reported in humans. Warm and moist conditions are important to allow survival of ''A. caninum'' during the free-living stages of its lifecycle, so it is largely restricted to temperate, tropical, and subtropical regions. In parts of the world where these climatic requirements are met such as Sri Lanka, Southeast Asia, and Malaysia, ''A. caninum'' is the main cause of hookworm disease in canines. Morphology ''A. caninum'' females are typically long and wide, while the males are smaller at in length and in width. Males have copulatory bursa ...

Ancylostoma Ceylanicum
''Ancylostoma ceylanicum'' is a parasitic roundworm belonging to the genus ''Ancylostoma''. It is a hookworm both of humans and of other mammals such as dogs, cats, and golden hamsters. It is the only zoonotic hookworm species that is able to produce symptomatic infections in humans, with the majority of cases being in Southeast Asia. Discovery and history Since the description of ''Ancylostoma ceylanicum'' by Arthur Looss in 1911, and '' A. braziliense'' by Gomes de Faria in 1910, the two species were considered synonymous because of their apparent similarities in almost all respects. In 1913, comparison of specimens from human, dog, cat and lion infections in India led to the conclusion that they were definitely identical. In 1915 Gomes de Faria described the anatomical structures and concluded that the two were distinct species. Until 1921 ''A. ceylanicum'' was accepted as a valid species. However, in 1922 Gordon made an exhaustive comparison from specimens collected in Brazil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Ancylostoma Tubaeforme
''Ancylostoma tubaeforme'' is a hookworm that infects cats worldwide. Infection can occur through penetration of the skin, ingestion of infected hosts, such as birds, or by directly consuming the organism. ''Ancylostoma tubaeforme'' along with ''Ancylostoma braziliense'' are the two most common hookworms to infect cats, causing anemia and compromising the immune system. Morphology The body of an adult A. tubaeforme is between 7 to 12 millimeters long. Youssefi, M. R., Hoseini, S. H., Hoseini, S. M., Zaheri, B. A., & Tabari, M. A. (2010). First report of Ancylostoma tubaeforme in Persian Leopard (Panthera pardus saxicolor). Iranian Journal of Parasitology, 5(1), 61–63. Signs ''Ancylostoma tubaeforme'' infection may lead to dermatitis, anemia, weight loss, and pulmonary lesions. Life cycle ''Ancylostoma tubaeforme'' larvae may infect a host through oral ingestion or through skin lesions. Larvae ingested by the host pass through the esophagus into the stomach. From there, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancylostomiasis
Ancylostomiasis is a hookworm disease caused by infection with Ancylostoma hookworms. The name is derived from Greek ancylos αγκύλος "crooked, bent" and stoma στόμα "mouth". Ancylostomiasis is also known as miner's anaemia, tunnel disease, brickmaker's anaemia and Egyptian chlorosis. Helminthiasis may also refer to ancylostomiasis, but this term also refers to all other parasitic worm diseases as well. In the United Kingdom, if acquired in the context of working in a mine, the condition is eligible for Industrial Injuries Disability Benefit. It is a prescribed disease (B4) under the relevant legislation.§ Ancylostomiasis is caused when hookworms, present in large numbers, produce an iron deficiency anemia by sucking blood from the host's intestinal walls. Signs and symptoms Depending on the organism, the signs and symptoms vary. ''Ancylostoma duodenale'' and ''Necator americanus'' can enter the blood stream while '' Ancylostoma braziliensis'' cannot.
