The virus first binds to its host cell via specific sialic acid residues, which can control the species tropism of the virus. This protein was found to have sialic acid-sensitive toxic activity. One of several other carbohydrates is sialic acid which is known to have multiple roles in interactions between hosts and pathogens. Alternatively the sterical structure of sialic acid molecules in solution may be different from those bound to the erythrocyte surface to attach to the merozoites. The complex glycans of plants do not have terminal sialic acid residues. Pre-treatment with neuraminidase did not affect lectin binding, indicating that no additional binding sites were exposed on removal of terminal sialic acid residues. It seems to be likely that lipids, including glycolipids abundant in the gut tissue, hide the lectin binding site for sialic acid. Influenza viruses use sialic acid residues on the surface of vertebrate cell membranes as receptors for infecting cells. Gangliosides, sialic acid-containing glycosphingolipids, are located at the surface of the cell membrane with the hydrophilic oligosaccharide chain extending into the extracellular space. Ticks are devoid of sialic acid. Transcription regulation through sequence variation in these promoters is therefore another important potential control mechanism for meningococci that incorporate sialic acid as part of their capsule. It is responsible for binding the virus to cells with sialic acid on the membranes, such as cells in the upper respiratory tract or erythrocytes.
