ATCvet code: QI09AB07.
The product stimulates the development of active immunity against G. parasuis serotype 5. Serotype 5 is the most prevalent under the virulent serotypes of G. parasuis. There is some cross protection to the other virulent serotypes, but full cross protection cannot be assured. The product stimulates transfer of passive immunity against G. parasuis serotype 5 and 4 to the progeny after vaccination of pregnant sows. It contains an aqueous adjuvant.
The vaccine is of benefit when pigs and sows with no or low levels of antibodies against G. parasuis serotype 5 are mixed with animals from or in an environment with higher prevalence of Glässers disease or if the piglets from sows with no or low antibodies are reared in such environment. Vaccination of sows with moderate to high levels of antibodies has not been shown to provide additional protection of the offspring. The control of Glässers disease is also dependent on management factors and reduction of stress.
Antibodies against G. parasuis serotype 5 have been shown to be cross-reactive against H. parasuis serotype 4.
