TETRASACCHARIDES FOR THE DIAGNOSIS, PREVENTION, AND TREATMENT OF MELIOIDOSIS AND GLANDERS

摘要

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.
