A Polysaccharide from Hydatid Cyst Fluid
GWEN M. MACNAB
Top of pageAbstract
A SEROLOGICALLY active polysaccharide has been isolated from hydatid cyst fluid from an infested sheep. A positive precipitin reaction was obtained with the serum from a patient suffering from pulmonary hydatid disease, when dilute solutions of this polysaccharide were used as an antigen. Serum giving positive and negative Wassermann results showed no precipitin reaction with this same antigen.
