非洲猪瘟(ASF)是家猪和野猪的一种毁灭性的病毒性传染病,自从2018年8月我国发生非洲猪瘟疫情以来,严重危害生猪养殖业.非洲猪瘟病毒(ASFV)在我国已定殖并形成较大污染面,目前既没有安全有效的预防疫苗,也无有效的治疗药物,传播途径多且复杂,防控形势依然严峻,结合防控工作实践,提出后非洲猪瘟时代常态化综合防控措施的思...     

非洲猪瘟疫情后生猪复养生产探讨

非洲猪瘟是由非洲猪瘟病毒引起家猪和野猪等猪科动物的1种急性、高度接触性传染病。自2018年8月首例非洲猪瘟疫情在我国东北地区发生以来,1年多的时间疫情蔓延整个大陆,席卷全国31个省(自治区、直辖市),给养猪业和国民经济造成严重经济损失。当前和今后相当长的一段时期内,非洲猪瘟防控将是我国动物疫病防控的1项常态化工作。笔者在动物疫病防控一线参与非洲猪瘟防控处置工作,现结合工作实际,就非洲猪瘟疫情后如何开展生猪复养生产探讨如下,供参考。

非洲猪瘟防控与恢复生猪生产

关于非洲猪瘟防控1.非洲猪瘟疫情发生情况2018年8月3日公布第一起疫情,截至2019年12月12日,全国共发生非洲猪瘟疫情161起(其中,野猪疫情4起),共扑杀生猪119.4万头。目前已解除160起,只有云南1起疫情尚未解除疫区封锁,其余30个省份的疫区已全部解除封锁。今年以来,全国共报告新发非洲猪瘟疫情62起。     

中小养猪场对非洲猪瘟的防控措施

<正>非洲猪瘟是由非洲猪瘟病毒引起的家猪、野猪的一种急性、热性或高度接触性传染病,猪不分品种和年龄均可感染,引起的发病率和死亡率可达100%。非洲猪瘟不感染人类,也不是人畜共患传染病。我国生猪养殖户对疫病的防范意识不强,所具备的防范措施也不完善,而且生猪的调运频次非常高、数量也非常多,进而发生疫情和传播疫情的可能性会加大,此次非洲猪瘟的突然传入已给养猪业造成了巨大的损失。所以,非洲猪瘟的防控措施除了需要政府采取措施外,养     

Heartworm in dogs in Canada in 1984

In late December 1984, 1853 institutional veterinarians and small and mixed animal clinics across Canada were sent a questionnaire in order to assess the status of Dirofilaria immitis in Canada in 1984 and 35% of them responded. Veterinarians reported that 97,794 dogs were blood-tested to check for microfilariae and 1417 dogs (1.45% of those tested) were found with heartworm. Another 34 dogs were amicrofilaremic, but were diagnosed as having heartworm disease, to give the total number diagnosed in 1984 as 1451 (1.48%). Heartworm was reported from all provinces except Prince Edward Island and Newfoundland but most (1310) of the cases were in Ontario. In Quebec, 126 cases were reported mostly from west of Montreal.

Heartworm was found most frequently in companion dogs over three years of age maintained mainly outdoors in rural areas. About 27% of the cases were observed with clinical signs of heartworm disease and 72% had a history of not having left Canada. Southwestern Ontario continued to be the primary focus of the infection.
