Abstract

Brucellosis is an infectious and contagious disease caused by bacteria from the genus Brucella spp, that affects various species of animals and the humans. In cattle the main manifestation is the abortion that occurs around the seventh month of pregnancy. After infection, abortion often is in the first pregnancy, but due to the development of cellular immunity, it is rare in the second pregnancy after infection, and in the subsequent pregnancies are very rare. It is estimated that brucellosis causes losses of 20 to 25% in milk production due to miscarriages and fertility problems. Were collected and evaluated by the antigen test acidified buffered (TAAT) 114 serum samples from female cattle in milk, distributed in 19 properties in the municipality of Alegre in southern state of Espírito Santo during the year of 2007. On the 114 samples tested were found four positive reagents from three different farms. Keywords: Epidemiology, brucellosis, TAAT.
