摘要

Four hundred and twenty samples of raw cow, buffalo and sheep milk were collected through August 2006 to July 2007 from different sites in the Basrah province of Iraq and tested in the milk ring test to detect Brucella antibodies. Positive results were obtained in 24.2 of samples. By means of the enrichment broth technique, 62 Brucella isolates, 33 Brucella abortus isolates (biotypes 2, 3, 4 and 6); 25 B. melitensis isolates (biotypes 2 and 3), and 4 B. ovis isolates were recovered. The highest incidence of Brucella in raw milk samples was found out in sheep's milk followed by buffalo's raw milk. The prevalence of Brucella isolates was high in spring and summer months whereas a lower incidence was found out in cold months. Antibiotic sensitivity tests of the isolates were performed. All Brucella isolates showed an ability to grow within the temperature range 18-44 degrees C and at pH 4-9.
