A tetrasaccharide of formula I and a method of production thereof are provided. Furthermore, a conjugate comprising the tetrasaccharide and a molecule attached to the tetrasaccharide, preferably via its amine group, is also provided. Compositions, preferably immunogenic or vaccine compositions, comprising this tetrasaccharide or this conjugate are also provided. Such tetrasaccharides, conjugates, and compositions can be used for preventing or treating a disease caused by a Burkholderia infection in a subject, for inducing the production of anti-Burkholderia antibodies in a subject, or for diagnosing a Burkholderia infection in a subject. Preferably, the Burkholderia infection is an infection by Burkholderia pseudomallei (Bp) or Burkholderia mallei (Bm); the disease is melioidosis or glander; and/or the anti-Burkholderia antibodies are anti-Burkholderia pseudomallei (Bp) antibodies or anti-Burkholderia mallei (Bm) antibodies.
提供了一种具有式I的四糖和其生产方法。此外,还提供了包括该四糖和连接到该四糖上的分子(优选通过其胺基团连接)的共轭物。还提供了包括该四糖或该共轭物的组合物,优选为免疫原性或疫苗组合物。这些四糖、共轭物和组合物可用于预防或治疗由布氏杆菌感染引起的疾病,可用于在受试者中诱导抗布氏杆菌抗体的产生,或用于诊断受试者中的布氏杆菌感染。优选,布氏杆菌感染是由假痈疽布氏菌(Bp)或马勒布氏菌(Bm)引起的感染;疾病是痈疽病或疥疮;和/或抗布氏杆菌抗体是抗布氏假痈疽菌(Bp)抗体或抗布氏马勒菌(Bm)抗体。
