Abstract: Brucella are very small, gram-negative coccobacilli that cause a zoonosis called brucellosis. These bacteria enter the body through mucous membranes. The blood carries Brucella to organs such as the liver, spleen, bone marrow and kidneys where they cause lesions. Symptoms of brucellosis include fluctuating fever, chills, sweating, headache, muscle pain and weight loss. One species of Brucella called B. abortus infects the placenta and fetus of gestating cows and causes the fetus to abort. When humans are infected by this organism they develop a severe fever. Cow and sheep production in this region is an important livelihood source. In this study, 300 milk samples were collected from villages of Toyserkan City in seasons autumn 2009 were collected randomly from cows and sheeps of different ages This milk samples were examined for detecting Brucella abortus and Brucella melitensis with Milk Ring Test (MRT). From 300 milk samples which collected from milk samples about B. abortus 21 (14%) and B. melitensis 18 (12%) showed positive reaction with Milk Ring Test.
