The ring test for the detection of brucellosis in sheep and goats.

, : The ring test for the detection of brucellosis in sheep and goats.. Industr. lait, Paris, 140, 111-12

Milk samples from 134 flocks of sheep (8, 000 animals in all) were tested using the ring test. The reaction was specific when using either individual or pooled samples. This test was compared with serum agglutination, whey agglutination and an intradermal test in 65 sheep. Of these, 60 had serum agglutinins, 61 gave a positive intradermal reaction, 23 had a positive whey agglutination titre and 37 were positive to the ring test.
