網(wǎng)上豬這塊的博卡病毒資料不多。在人身上有相關(guān)的研究,有個(gè)也叫博卡病毒,但是查其英文名,好像不一樣。貼出來讓大家看看, Human bocavirus (HBoV)作者: 東方不敗10號(hào) 時(shí)間: 2011-7-10 11:34
大豬如果接種細(xì)小病毒疫苗,很快能控制腹瀉的話, 如果是真的話,只能說明這個(gè)病毒的抗原性和細(xì)小病毒差不多。作者: 畜牧工作者 時(shí)間: 2011-7-10 11:57

如果真的用細(xì)小病毒活苗,注射能控制的話就好了,一線用過的朋友多介紹下,謝謝作者: lzm_001 時(shí)間: 2011-7-10 13:47

1、Kobuviruses are members of the large and growing family Picornaviridae. Until now, two official, Aichi virus and Bovine kobuvirus, and one candidate kobuvirus species, 'porcine kobuvirus', have been identified in human, cattle and swine, respectively. In addition, kobu-like viruses were detected very recently in the bat. Aichi virus could be one of the causative agents of gastroenteritis in humans, and kobuviruses probably also cause diarrhoea in cattle and swine. Although Aichi virus has been detected relatively infrequently (0-3%) in human diarrhoea, high seroprevalence, up to 80-95% at the age of 30-40, was found indicating the general nature of infection in different human populations. In the previous years, much new information has accumulated relating to kobuviruses and their host species. This review summarises the current knowledge on kobuviruses including taxonomy, biology and viral characteristics, and covers all aspects of infection including epidemiology, clinical picture, host species diversity, laboratory diagnosis and it gives a summary about possible future perspectives.

KobuvirusFrom Wikipedia, the free encyclopedia
Kobuvirus is a viralgenus belonging to the family Picornaviridae. The genus is composed of three species, Aichi virus, Bovine kobuvirus and Porcine kobuvirus each possessing a single serotype. Aichi virus infects man (1,2), while bovine kobuvirus (3) and porcine kobuvirus (4,5), as suggested by its name, infects cattle and swine.
Virus particles
The molecular mass of a typical virion particle of this genus is typically eight to nine million. The virions of the viruses in this genus consist of capsids that are 27 to 30 nm in diameter (1). The capsid is described as being round and displaying icosahedral symmetry. The capsid is believed to consist of 12 capsomers and the capsid shell structure of these virions has a monolayer composition (1). Using conventional electron microscopy, the structure of the capsid surface can be visualised (1,2). The virus particles contain a single species of ssRNA. These virions have a sedimentation coefficient of 140-165 S20w. The particles are described to be “relatively stable” in vitro (in comparison to other viruses) and stable in acidic conditions of pH 3.5 (2). They have also been found to be insensitive to treatment with some chemicals including chloroform, ether and non-ionic detergents (2).
Genetics
The viruses in this genus have single-stranded, linear non-segmented, positive-sense RNA genomes with lengths of approximately 8.2-8.3 kb (2,3).
