Zusammenfassung:The invention relates to bacterial infections, vaccines directed against those infections and bacterial vaccines. More particularly, the invention relates to vaccines directed against Streptococcus infections in pigs. The invention provides a ΔFolT mutant of a bacterium having reduced capacity to transport folate, wherein said capacity has been reduced by functionally deleting folate transporter (FolT) function. The invention also provides a method to reduce virulence of a bacterium comprising reducing the capacity of said bacterium to transport folate.
