翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Human viruses in water ： ウィキペディア英語版 Human viruses in water Viruses are a major cause of human waterborne and water-related diseases. Waterborne diseases are caused by water that is contaminated by human and animal urine and feces that contain pathogenic microorganisms. A subject can get infected through contact with or consumption of the contaminated water.〔Waterborne diseases〕 Viruses affect all living organisms from single cellular plants, bacteria and animal to the highest forms of plants and animals including human beings. Viruses can interact with their host through several methods and mechanisms; some viruses can be host specific (HIV) and some can be less host specific (influenza) viruses.〔Virus〕 Different viruses can have different routes of transmission; for example, HIV is directly transferred by contaminated body fluids from an infected host into the tissue or bloodstream of a new host while influenza is airborne and transmitted through inhalation of contaminated air containing viral particles by a new host. Enteric viruses primarily infect the intestinal tract through ingestion of food and water contaminated with viruses of fecal origin. Some viruses can be transmitted through all three routes of transmission. Water virology started about half a century ago when scientists attempted to detect the polio virus in water samples.〔 Since then, other pathogenic viruses that are responsible for gastroenteritis, hepatitis, and many other virus strains have replaced enteroviruses as the main aim for detection in the water environment. ==History== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Human viruses in water」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
