Porcine parvovirus L strain and use thereof in preparation of porcine parvovirus inactivated vaccines

Номер: CN0101851609A
Принадлежит:

The invention discloses a porcine parvovirus L strain and use thereof in preparation of porcine parvovirus inactivated vaccines. In the invention, microbial preservation number of the separated strain is CGMCC No. 3352. The strain is highly homologous with an NADL-2 strain and a China strain and keeps high reproduction, and the viruses are stable. Oil adjuvant is added into antigen liquid which inactivates the viruses by using binary ethylenimine to prepare the bidirectional oil-emulsion inactivated vaccines; and the prepared inactivated vaccines are applied in a vaccine inoculation experiment of 10,276 pigs (most of which are first farrowing sows), and in the experiment, an immune dosage of 2 millimeters is given to each pig through muscle injection, and each time of inactivated vaccine inoculation can obtain an immune period of over 6 months. Under the conditions that a 10 millimeter overdose vaccine is injected into a pig and that single dose inoculation is repeatedly carried out for ...
