Problems solved by technology

However, virus chicken embryo culture is more common in the cultivation of some higher animal viruses, and its research and application in the field of aquatic animal viruses is extremely rare
At present, there is no relevant research report on the method of cultivating crab viruses including portunus trituberculatus reovirus by using chicken embryo culture method at home and abroad

Embodiment Construction

[0024] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0025] The following examples further illustrate the present invention, but the protection scope of the present invention is not limited thereto, and the protection scope is defined by the claims.

[0026] The chicken embryo culture method of Portunus trituberculatus reovirus of the present invention adopts SPF chicken embryos as the in vitro culture system of Portunus trituberculatus reovirus, selects healthy chicken embryos that have been cultivated for 3-4 days in advance, and prepares the prepared chicken embryos in advance. Portunus trituberculatus reovirus inoculum was inoculated onto the allantoic membrane of chicken embryos, and the culture continued until the chicken embryos died. The dead chicken embryos that had been cultured for 3-10 days were collected for homogenization and centrifugation to extract Portunus trituberculatus reo. ...

Abstract

The invention discloses a chicken embryo culture method of Portunus tritubereulatus reovirus and is characterized by comprising the following steps of: using SPF chicken embryo as an in vitro culture system of Portunus tritubereulatus reovirus, selecting healthy chicken embryo of 3 and 4 days-old, inoculating a prepared Portunus tritubereulatus reovirus inoculated solution onto a chorioallantoic membrane of the chicken embryo, continuously culturing until the chicken embryo is dead, collecting dead chicken embryo cultured for 3-10 days, separating the chorioallantoic membrane and amniotic fluid, mixing the chorioallantoic membrane and the amniotic fluid, homogenizing the mixture, centrifuging and filtering to obtain a supernatant of Portunus tritubereulatus reovirus. The invention has the following advantages: a more efficient and adaptive Portunus tritubereulatus reovirus in vitro culture method is provided for rapid and effective in vitro subcultring of the virus; and the method overcomes the defect that there is no adaptive culture system during the culture process of Portunus tritubereulatus reovirus, fills the blank of chicken embryo culture system of crab virus and has laid a foundation for further research and application.

Description

Technical field [0001] The present invention involves the in vitro culture method of three warted crab crabs, especially the chicken embryo culture method involving three warted canar crab to be lonely virus. Background technique [0002] The vertical virus is a virus with a wide range of hosts, and its host can cover mammals, poultry, insects, aquatic animals, etc.A type of intestinal orprovi virus infected with aquatic creatures is classified as aquatic human be lonely virus.MEYERS is equal to the first separation from American oysters to aquatic intestinal virus.There are currently more than 40 lone viruses that are separated from the appraisal.These viruses are mainly infected with the host through breathing and intestine, causing hosts to hemorrhoids and diseases of the liver and pancreas.It has caused huge losses in the global aquaculture industry and seriously threatened the development of the aquaculture industry.Aquatic intestinal virus is a general virus in aquatic anim...
