摘要：

The presence of Shiga-toxin producing Escherichia coli (STEC) was evaluated in bulk milk from dairy cattle farms in Bulgaria. From 20 regional farms only 4 were selected as a source for milk sampling on the basis of their annual STEC shedding in feces. All the samples were PCR analyzed after selective enrichment. Positive samples were detected in subsequent molecular testing as: two of samples (9.08%) were positive for stx(1), one sample (4.54%) for stx(2), 10 samples (45.54%) for eae and 12 (54.54%) for H7 coding genes.
