Abstract
Capsular polysaccharides (CPSs) were isolated from O-polysaccharide deficient strains of Burkholderia mallei and Burkholderia pseudomallei using a modified hot phenol/water extraction procedure. Glycosyl composition, methylation, MALDI-TOF MS analyses as well as (1)H NMR spectroscopy including COSY, TOCSY, NOESY, HMBC and HSQC experiments identified the presence of two distinct CPS antigens in the samples exhibiting the following structures: This study confirms the ability of B. mallei to express a 6-deoxy-heptan CPS and represents the first report of a mannan CPS being expressed by these bacterial pathogens.Entities:
