Abstract

The invention discloses a trigeminy inactivated vaccine for porcine circovirus disease, porcine streptococcus suis disease and porcine haemophilus parasuis disease, a preparation method of the vaccine and applications of the vaccine. Porcine circovirus 2-WH has an accession number of CCTCC NO: V20133 and has strong virulence, good immunogenicity, a high antigen titer, and a high virulence reaching 10<7.4>TCID[50] / mL. The trigeminy inactivated vaccine, which is prepared by mixing the porcine circovirus 2-WH, porcine streptococcus suis 2-LT, and porcine haemophilus parasuis 4-MD0322 and porcine haemophilus parasuis 5-SH0165, can simultaneously prevent the porcine circovirus disease and diseases caused by porcine streptococcus suis 2-type, porcine haemophilus parasuis 4-type and porcine haemophilus parasuis 5-type, the immune protective effect on the same serotype reaches over 80%.

Description

technical field

[0001] The invention relates to the field of biotechnology, in particular to a triple inactivated vaccine for porcine circovirus disease, suis streptococcosis and haemophilus parasuis disease, and also relates to a porcine circovirus disease, suis streptococcosis and parasuis haemophilus disease The preparation method of the bacillosis triple inactivated vaccine also relates to the application of a triple inactivated vaccine of porcine circovirus disease, suis streptococcus disease and Haemophilus parasuis disease. The triple inactivated vaccine prepared by the invention is mainly suitable for sows, boars and piglets, and has good immune effect. technical background

[0002] Porcine circovirus type 2 infection is the main cause of multisystemic wasting syndrome (PMWS) in weaned pigs, and other synergistic factors can enhance the severity of the disease. Porcine circovirus disease can cause the infected pigs to become thin, grow slowly, and reduce feed remune...
