There is provided a molecule comprising a chain of seven or more contiguous units of 4,6-dideoxy-4-acylamido-α-pyranose each pair of units joined by a C-Cor a C-Clink, the chain having a terminal end and a reducing end, wherein the pyranose ring in the unit of the chain most distal from the reducing end is linked to a cap structure. The cap structure is not a 4,6-dideoxy-4-acylamido-α-pyranose. There are also provided vaccine compositions comprising the molecule and methods of vaccinating an animal against infection by aorganism, including methods of distinguishing between a vaccinated and an infected animal. There are further provided novel methods of detecting the presence in a sample of an anti-antibody.

Polysaccharide and methods

There is provided a molecule comprising a chain of seven or more contiguous units of 4,6-dideoxy-4-acylamido-&#x3b1;-pyranose, each pair of units joined by a C-Cor a C-Clink, the chain having a terminal end and a reducing end, wherein the pyranose ring in the unit of the chain most distal from the reducing end is linked to a cap structure. The cap structure is not a 4,6-dideoxy-4-acylamido-&#x3b1;-pyranose. There are also provided vaccine compositions comprising the molecule and methods of vaccinating an animal NI against infection by aorganism, including methods of distinguishing between a vaccinated and an infected animal. There are further provided novel methods of detecting the presence in a sample of an anti-antibody.
