Abstract
Animals' sera collected on Easter Island from December 1964 to February 1965 were tested by appropriate methods for the presence of antibodies to various infections. These included, ornithosis, Q-fever, brucellosis, Johne's disease, leptospirosis, toxoplasmosis and vesicular stomatitis viruses. It appeared that the cattle and sheep were exposed to the ornithosis group of agents. The sheep were also exposed to toxoplasmosis. The low-grade reactions observed on the cattle sera with the leptospira and brucella antigens were not sufficient to indicate past infection. All sera tested with Q-fever and Johne's disease antigens gave negative reactions. The results suggested that neither strain of vesicular stomatitis virus had yet been introduced into this restricted animal population.
