[Allergic diagnosis of abortive chlamydial infection in the goat (author's transl)]

A delayed hypersensitivity test was used for chlamydiosis diagnosis in four goat flocks. The skin-test was performed in the neck by inoculating 100 microgram of purified Chlamydia from yolk sac or McCoy cells. The reactions were read 72 h after inoculation. The two antigens gave the same results. The number of doubtful reactions observed was significantly smaller in hypersensitivity than in the complement fixation test.
