(20) It was shown that at HAg greater than or equal to 25% the strains used for antigen and antibody generation were closely related and at HAg less than or equal to 6.25% belonged to different subtypes.
Lamprey
Definition:
(n.) An eel-like marsipobranch of the genus Petromyzon, and allied genera. The lampreys have a round, sucking mouth, without jaws, but set with numerous minute teeth, and one to three larger teeth on the palate (see Illust. of Cyclostomi). There are seven small branchial openings on each side.
