Between 2002 and 2007, 75 strains of Brucella abortus were isolated from aborted bovine fetuses collected from several regions of Turkey. The isolates were all identified as B abortus biovar 3 by conventional methods. However, when they were analysed by enhanced AMOS-ERY PCR, a 5-4 kb deletion, different from that in the Tulya strain (B abortus biovar 3, ATCC 23450), was identified in all of them. As a result, they were subtyped as B abortus biovar 3b.
