犬冠状病毒病

犬冠状病毒病. 概 述. 犬冠状病毒病 ( CCD )是犬的一种急性胃肠道传染病。 临诊特征 : 腹泻。发病急、 传染快、病程短 。如与犬细小病毒或轮状病毒混合感染,病情加剧,常因急性腹泻、呕吐、脱水迅速死亡。. 犬冠状病毒( CCV )是冠状病毒科冠状病毒属成员,有囊膜,核内含单股 RNA 。 病毒对外界环境的抵抗力较强。粪便中的病毒可存活 6 ~ 9 天,污染物在水中可保持数天传染性。 CCV 对热、乙醚、氯仿及去氧胆酸钠敏感。紫外线和其它消毒剂都可灭活 CCV 。. 病原学. 流行病学. 病犬是最主要的传染来源。.

  2. 概 述 犬冠状病毒病(CCD)是犬的一种急性胃肠道传染病。 临诊特征:腹泻。发病急、 传染快、病程短。如与犬细小病毒或轮状病毒混合感染,病情加剧,常因急性腹泻、呕吐、脱水迅速死亡。

  3. 犬冠状病毒(CCV)是冠状病毒科冠状病毒属成员,有囊膜,核内含单股RNA。犬冠状病毒(CCV)是冠状病毒科冠状病毒属成员,有囊膜,核内含单股RNA。 病毒对外界环境的抵抗力较强。粪便中的病毒可存活6~9天,污染物在水中可保持数天传染性。CCV对热、乙醚、氯仿及去氧胆酸钠敏感。紫外线和其它消毒剂都可灭活CCV。 病原学

  4. 流行病学 病犬是最主要的传染来源。 CCV主要存在于病犬的胃肠道内,并随粪便排出,污染饲料、饮水和周围环境,经消化道感染易感犬。 本病仅感染犬、狐等犬科动物。各种品种和年龄的犬都易感,幼犬症状明显。
