SA11 Rotavirus Is Specifically Inhibited by an Acetylated Sialic Acid

Abstract
Bovine salivary mucin (BSM) inhibits rotavirus replication in vitro and in vivo. The inhibitory effect of BSM in vitro is abolished by Arthrobacter ureafaciens neuraminidase but not by Clostridia perfringens neuraminidase; it is abolished by mild base deacetylation but not by influenza C acetylesterase. The data suggest that SA11 rotavirus binds to a specific sialic acid structure on BSM different from the sialic acids recognized by other viruses.
