Influenza A Virus Subtype H5N2
H5 N2 is a subtype of the species Influenzavirus A (avian influenza virus or bird flu virus). The subtype infects a wide variety of birds, including chickens, ducks, turkeys, falcons, and ostriches. Affected birds usually do not appear ill, and the disease is often mild as avian influenza viral subtypes go. Some variants of the subtype are much more pathogenic than others, and outbreaks of "high-path" H5N2 result in the culling of thousands of birds in poultry farms from time to time. It appears that people who work with birds can be infected by the virus, but suffer hardly any noticeable health effects. Even people exposed to the highly pathogenic H5N2 variety that killed ostrich chicks in South Africa only seem to have developed conjunctivitis, or a perhaps a mild respiratory illness. There is no evidence of human-to-human spread of H5N2. On November 12, 2005 it was reported that a falcon was found to have H5N2. Vaccine In China, inactivated H5N2 has been effectively used a ...

Hemagglutinin
In molecular biology, hemagglutinins (or ''haemagglutinin'' in British English) (from the Greek , 'blood' + Latin , 'glue') are receptor-binding membrane fusion glycoproteins produced by viruses in the ''Paramyxoviridae'' family. Hemagglutinins are responsible for binding to receptors on red blood cells to initiate viral attachment and infection. The agglutination of red cells occurs when antibodies on one cell bind to those on others, causing amorphous aggregates of clumped cells.Hemagglutinins recognize cell-surface glycoconjugates containing sialic acid on the surface of host red blood cells with a low affinity, and use them to enter the endosome of host cells. In the endosome, hemagglutinins are activated at a pH of 5 - 6.5, to undergo conformational changes that enable viral attachment through a fusion peptide. Agglutination and hemagglutinins were discovered by virologist George K. Hirst in 1941. Alfred Gottschalk proved in 1957 that hemagglutinins bind a virus to a host c ...

Poultry Farming
Poultry farming is the form of animal husbandry which raises domesticated birds such as chickens, ducks, turkeys and geese to produce meat or eggs for food. Poultry – mostly chickens – are farmed in great numbers. More than 60 billion chickens are killed for consumption annually. Chickens raised for eggs are known as layers, while chickens raised for meat are called broilers. In the United States, the national organization overseeing poultry production is the Food and Drug Administration (FDA). In the UK, the national organisation is the Department for Environment, Food and Rural Affairs (Defra). Intensive and alternative According to the World Watch Institute, 74 percent of the world's poultry meat, and 68 percent of eggs are produced intensively.''State of the World 2006'' World "atch Institute, p. 26 One alternative to intensive poultry farming is free-range farming using lower stocking densities. Poultry producers routinely use nationally approved medications, such a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moca, Dominican Republic
Moca is the capital of Espaillat province in the Cibao region of the Dominican Republic, and is the tenth-largest city of the country with a population of 173,442 inhabitants. Moca is located 11 miles/18 kilometers east from the country’s second-largest city, Santiago. It is divided into eight municipal districts: San Víctor, Las Lagunas, José Contreras, Juan López, El Higuerito, La Ortega, Monte de la Jagua and Canca La Reina. The city is known as "La Villa Heroica" (Village of Heroes) due to the number of men and women from Moca who have played a major role in the Dominican Republic's history in bringing down two dictators, Ulises Heureaux and Rafael Trujillo, and bringing democracy back to the country. Moca is home to the Corazon Sagrado de Jesus ("Sacred Heart of Jesus") Cathedral. All its pane glass windows were originally brought from Italy depicting the apostles and Jesus' path to the crucifixion. Agriculture forms the primary livelihood of the inhabitants. Plantai ...

Compost
Compost is a mixture of ingredients used as plant fertilizer and to improve soil's physical, chemical and biological properties. It is commonly prepared by decomposing plant, food waste, recycling organic materials and manure. The resulting mixture is rich in plant nutrients and beneficial organisms, such as bacteria, protozoa, nematodes and fungi. Compost improves soil fertility in gardens, landscaping, horticulture, urban agriculture, and organic farming, reducing dependency on commercial chemical fertilizers. The benefits of compost include providing nutrients to crops as fertilizer, acting as a soil conditioner, increasing the humus or humic acid contents of the soil, and introducing beneficial microbes that help to suppress pathogens in the soil and reduce soil-borne diseases. At the simplest level, composting requires gathering a mix of 'greens' (green waste) and 'browns' (brown waste). Greens are materials rich in nitrogen such as leaves, grass, and food scraps. Br ...

Canadian Food Inspection Agency
The Canadian Food Inspection Agency (CFIA; french: Agence canadienne d'inspection des aliments) is a regulatory agency that is dedicated to the safeguarding of food, plants, and animals (FPA) in Canada, thus enhancing the health and well-being of Canada's people, environment and economy. The agency is governed by the Minister of Agriculture and Agri-Food and Minister of Health. The agency was created in April 1997 by the ''Canadian Food Inspection Agency Act'' for the purpose of consolidating the delivery of all federal food safety, animal health, and plant health regulatory programs in Canada. As such, the CFIA was established by combining and integrating the related inspection services of three separate federal government departments: * Agriculture and Agri-Food Canada, * Fisheries and Oceans Canada, and * Health Canada. Role and responsibilities The agency is part of the larger federal public service. According to the CFIA statement of values, science is the basis for r ...

Fraser Valley
The Fraser Valley is a geographical region in southwestern British Columbia, Canada and northwestern Washington State. It starts just west of Hope in a narrow valley encompassing the Fraser River and ends at the Pacific Ocean stretching from the North Shore Mountains, opposite the city of Vancouver BC, to just south of Bellingham, Washington. In casual usage it typically describes the Fraser River basin downstream of the Fraser Canyon. The term is sometimes used outside British Columbia to refer to the entire Fraser River sections including the Fraser Canyon and up from there to its headwaters, but in general British Columbian usage the term refers to the stretch of Lower Mainland west of the Coquihalla River mouth at the inland town of Hope, and includes all of the Canadian portion of the Fraser Lowland as well as the valleys and upland areas flanking it. It is divided into the Upper Fraser Valley and Lower Fraser Valley by the Vedder River mouth at the eastern foothills ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
British Columbia
British Columbia (commonly abbreviated as BC) is the westernmost province of Canada, situated between the Pacific Ocean and the Rocky Mountains. It has a diverse geography, with rugged landscapes that include rocky coastlines, sandy beaches, forests, lakes, mountains, inland deserts and grassy plains, and borders the province of Alberta to the east and the Yukon and Northwest Territories to the north. With an estimated population of 5.3million as of 2022, it is Canada's third-most populous province. The capital of British Columbia is Victoria and its largest city is Vancouver. Vancouver is the third-largest metropolitan area in Canada; the 2021 census recorded 2.6million people in Metro Vancouver. The first known human inhabitants of the area settled in British Columbia at least 10,000 years ago. Such groups include the Coast Salish, Tsilhqotʼin, and Haida peoples, among many others. One of the earliest British settlements in the area was Fort Victoria, established ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
