Hepatitis transmission in marmosets.

The Barker and Berlin strains of hepatitis agent were serially passaged in cotton-topped marmosets, but attempts to isolate a new strain were unsuccessful. Cross-protection tests suggested that the Barker and Berlin agents were serologically related, but normal human immunoglobulin did not protect animals against the Berlin agent. The difficulties encountered in working with captured wild marmosets were considered.
