The presence of specific carbohydrates on viral surface structures, de
veloping an important role in their biological processes, was analysed
using Newcastle Disease Viruses (SO-93, B1 and La Sota strains) ind I
nfluenza virus (A/Influenza/PR/8/34 (H1N1) strain) as models. Virus sa
mples were concentrated by sedimentation process, purified by tartrate
gradient, they were washed through another sedimentation step and eva
luated by their protein content, hemagglutination titer and carbohydra
te residues. This study developed with lectins and specific sugars cou
ld show carbohydrates as essential elements of virus surface structure
s, which were revealed for inhibition of precipitation lines among con
canavalin A and Newcastle Disease Virus specific serum.
