Susceptibility of tamarins (Saguinus) to measles virus.

Tamarins (Saguinus mystax and Saguinus labiatus) were experimentally infected with two strains of measles virus. One of the strains (JM) spread readily among the animals with a high fatality rate. The second strain (Edmonston) appeared to be less pathogenic and less transmissible than strain JM. Aerosol was considered the most probable mode of infection.
