Abstract

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.

Claims (4)

1. A method for reducing the percentage of concomitant infections by more than 10% in pigs or a herd of pigs caused by one or more pathogens other than PCV2 comprising the step of administering to the pigs a single dose of PCV2 ORF2 composition or an immunogenic composition comprising PCV2 ORF2, wherein the PCV2 ORF2 composition or immunogenic composition comprises a polymer of acrylic or methacrylic acid and 4-400 μg PCV2 ORF2 and wherein reducing the percentage of concomitant infections occurs after a single dose and is in comparison to pigs not receiving the PCV2 ORF2 composition or immunogenic composition and wherein the concomitant infections are selected from the group consisting of Actinobacillus pleuropneumoniae, Haemophilus parasuis, Mycoplasma hyrhinis, Mycoplasma hyopneumoniae, Pasteurella multocida, Salmonella spp., Strepococcus suis , and combinations thereof.

2. The method of claim 1 , wherein the pigs or herd of pigs are/is infected with PCV2.

3. A method for improving the resistance of pigs against concomitant infections with one or more pathogens other than PCV2, comprising the step of administering to the pig(s) a single dose of PCV2 ORF2 composition or an immunogenic composition comprising PCV2 ORF2, wherein the PCV2 ORF2 composition or immunogenic composition comprises a polymer of acrylic or methacrylic acid and 4-400 μg PCV2 ORF2 and wherein the number of pigs infected with one or more of the pathogens other than PCV2 is reduced with regard to one of more of the pathogens by more than 10% after a single dose of the PCV2 ORF2 composition or immunogenic composition comprising PCV2 ORF2 when compared to those pigs not receiving the PCV2 ORF2 composition or immunogenic composition, and wherein the concomitant infections are selected from the group consisting of Actinobacillus pleuropneumoniae, Haemophilus parasuis, Mycoplasma hyrhinis, Mycoplasma hyopneumoniae, Pasteurella multocida, Salmonella spp., Strepococcus suis , and combinations thereof.

4. The method of claim 3 , wherein the pigs are infected with PCV2.
