Out of a total of 2,368 sheep and 3,156 goats tested against brucellosis by the Brewer's card test in the 5 Mohafadhas of the northern region of Iraq, 0.93% and 4.4% respectively were recorded as positive reactors. The highest incidence (1.36%) among sheep was found in the Kirkuk region while the lowest (0.78%) was in the Mosul (Nineveh) region. Among goats the highest incidence (11.55%) was revealed in the Dukho region while the lowest (1.47%) was in the Sulaimaniya region. The need for more detailed work on the incidence and on the isolation of the local strains, as well as the need for a control programme, is also discussed.
