Monodontus
''Monodontus'' is a genus of parasitic nematodes in the subfamily Bunostominae of family Ancylostomatidae. Most of its species occur in rodents and suids, but '' Monodontus louisianensis'' is from the white-tailed deer (''Odocoileus virginianus'') and '' Monodontus giraffae'' from the giraffe (''Giraffa camelopardalis''). An unspecified ''Monodontus'' has been recorded from the marsh rice rat (''Oryzomys palustris'') in Florida.

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] |

Bunostomum
''Bunostomum'' is a genus of nematodes of the small intestine of ruminants and camelids. Important species include: ''B. phlebotomum'' in calves and ''B. trigonocephalum'' in lambs. The worms are stout and measure in length. Young animals are most commonly affected and only several hundred worms are necessary to cause morbidity. Adults often carry worms without showing clinical signs. Life cycle The life cycle is direct, with a prepatent period of 30-56 days. Eggs hatch on the ground and develop into infective larvae in several weeks. Larvae penetrate through the skin or are ingested and then migrate to the respiratory system, are coughed up and swallowed and finally reach the small intestine. Eggs are then shed in the feces of the infected host. Clinical signs and diagnosis Diarrhoea is the primary sign, along with systemic signs of anorexia, lethargy and weight loss if the worm burden is severe. Hypoproteinaemia, anaemia and dehydration often occur. Skin involvement due to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...
