摘要:
The present invention relates to the use of an immunogenic composition that comprises a PCV2 antigen for treatment of several clinical manifestations (diseases). Preferably, the clinical manifestations are associated with an enteric infection, even more preferably, with enteric disease. The use relates to a method comprising the steps of administering the composition to an animal in need thereof, preferably prior to disease exposure. Administration of PCV2 antigen, preferably ORF2 of PCV2, lessens the incidence and reduces the severity of the enteric disease.
摘要:
The present invention comprises methods and compositions related to the production and use of amino acid sequences. In particular, PCV2 ORF2 is shown to be useful as a virus-like particle which produces amino acid sequences that retain their immunogenicity or antigenicity when the DNA encoding the PCV2 ORF2 is inserted into an expression system. DNA sequences that are foreign to PCV2 can be attached “in-frame” to the ORF2 DNA and the entire sequence, including the DNA foreign to PCV2, is expressed. It was shown that such sequences retain their antigenicity and therefore their potential utility in immunogenic compositions.
摘要:
The present invention relates to a method for reducing the percentage of concomitant infections in pigs or a herd of pigs caused by pathogens other than PCV2 comprising the step administering to said pig(s) an effective amount of PCV2 antigen or an immunogenic composition comprising PCV2 antigen. It also refers to a method for improving the resistance of pigs against concomitant infections with pathogens other than PCV2, comprising the step administering to said pig(s) an effective amount of PCV2 antigen or an immunogenic composition comprising PCV2 antigen.
摘要:
The present invention relates to new attenuated M. bovis bacteria strains passaged at least 110 times. Moreover, the present invention also provides immunogenic compositions comprising live bacteria of any of those attenuated M. bovis bacteria strain, their manufacture and use for the treatment and prophylaxis of M. bovis infections and combinations with other veterinary vaccines or medicaments.
摘要:
The present invention relates inter alia to the use of a combination of a vaccine against Lawsonia intracellularis and an anti-Lawsonia antibiotic for the prevention or reduction of early, preferably fulminant Lawsonia intracellularis infections. The present invention relates particularly to the use of a live Lawsonia intracellularis vaccine in conjunction with an antibiotic that is effective against Lawsonia intracellularis, for the avoidance or reduction of early Lawsonia intracellularis infections in animals.
摘要:
A method of predicting the virulence of a new or uncharacterized PRRS virus strain is provided wherein the strain is injected into swine and allowed to replicate for a period of from about 3-15 days. During this period, the rate of virus growth and/or the magnitude of viremia is determined, and this data is compared with a corresponding growth rate and/or viremia magnitude of a PRRS virus strain of known virulence, as a measure of the virulence of the new or uncharacterized strain.
摘要:
The present invention relates to new attenuated M. bovis bacteria strains. Moreover, the present invention also provides immunogenic compositions comprising live bacteria of an of those attenuated M. bovis bacteria strain, their manufacture and use for the treatment and prophylaxis of M. bovis infections.
摘要:
The present invention relates to Lawsonia intracellularis vaccines and methods for protecting against and diagnosing L. intracellularis infection. The products and processes of the invention are attainable, in part, as the result of an improved method for cultivating large scale supplies of L. intracellularis, including both a novel isolate of L. intracellularis of European origin and a method of preparing a lyophilized product containing the attenuated European isolate as vaccine product.
摘要:
A vaccine for protecting a horse against diseases associated with EHV-1 and/or EHV-4 is provided. The vaccine commonly includes inactivated EHV-1 (e.g., chemically inactivated EHV-1 KyA virus) and an adjuvant. The adjuvant can include a cross-linked olefinically unsaturated carboxylic acid polymer which may have bioadhesive properties. The vaccine may also include antigens against other equine pathogens such as inactivated EHV-4 and inactivated A1 and/or A2 strains of equine influenza virus. Methods for protecting horses against diseases associated with EHV-1 and/or EHV-4 and methods of producing the equine herpesvirus vaccine are also provided.
摘要:
The present invention provides combination vaccines that comprise an immunological agent effective for reducing the incidence of or lessening the severity of PPE caused by L. intracellularis, and one or more immunological active components effective in treatment and/or prophylaxis of at least one further disease-causing organism for swine. Moreover, the present invention also relates to a kit that comprises an immunological agent effective for reducing the incidence of or lessening the severity of PPE caused by L. intracellularis, and one or more immunological active components effective in treatment and/or prophylaxis of at least one further disease-causing organism for swine.
