Inhibition of binding of Norwalk viruslike particles (VLPs) to oyster digestive tissues by saliva

Saliva No. samples tested VLP binding*
A 14
O 18 +
B 4 +++
Nonsecretor 5 +++
Control 5 +++

*After incubation with saliva, no (–), weak (+), or strong (+++) VLP binding to oyster digestive tissues was observed. For controls, VLPs were applied to shellfish tissues in phosphate-buffered saline/1% bovine serum albumin instead of a saliva sample diluted in the same buffer.
