IV. The search for new amoebicidal drugs

(1) Methods which have been used in a large industrial research department in the search for new amoebicides are discussed. (2) New techniques of testing potential amoebicides in vitro and in an in vivo — in vitro tests in rats are described. (3) Results of three tests used have been compared. Correlation between the tests was sufficiently good for the simple tests to be acceptable.
