  Upgrading diagnostics: A universal antigen has been prepared for the detection of brucellosis caused by any Brucella species that express a smooth lipopolysaccharide. This nonasaccharide, which encompasses Brucella A‐ and M‐antigenic determinants, is uniquely available only by chemical synthesis.

  glycosides. The pentasaccharide analogues each have two formamido groups replaced by hydroxyl groups. Protected derivatives of the three oligosaccharides were prepared by in situ activation with bromine of mono- and di-saccharide thioglycosides of D-rhamnose and 4-azido-4,6-dideoxy-D-mannose in the presence of a glycosyl acceptor and silver triflate as promoter.
