翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Chronic bee paralysis virus ： ウィキペディア英語版 Chronic bee paralysis virus Chronic bee paralysis virus, abbreviated as CBPV, affects adult honey bees and causes a contagious case of chronic paralysis which can easily spread to other members of a colony. Symptoms include trembling of wings and body, loss of flight, loss of hair, and rejection by healthy members of the colony. Bees infected with CBPV die within a few days and is a factor in the loss of honeybee colonies. Although CBPV infects mainly adult bees, the virus may also deal damage to bees in all developmental stages, though developing bees contained significantly lower amounts of the virus compared to their adult counterparts. Death with regards to infected developing bees and brood losses are either low or nonexistent as well.〔 Bees that have been infected with CBPV may house millions of viral particles, with half of them concentrated in the head region, allowing it to cause symptoms similar to diseases relating to nervous system damage. In fact, viral particles have been found to concentrate in two centers; mushroom bodies involved in sensory processing, memory, learning, and motor control as well as the center dealing with locomotive control, behavior and orientation, and arousal.,〔 == Susceptibility == Worker bees are the most susceptible to infection due to injection, as a result of laboratory tests and the most efficient mode for spread of infection is close contact between healthy and infected bees in crowded areas. Although CBPV can easily spread due to close contact, contact between healthy bees and the feces of infected bees can also cause infection. Therefore, this viral infection may spread between hives as a result of this indirect contact. As a result of laboratory experiments, adult bees may become infected with CBPV by a viral injection, topical application, or by ingestion. 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「Chronic bee paralysis virus」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.
