ERIC iPCR fingerprints showed ten different bands ranging from 542 bp to 3,300 bp (Figure 1), while the most common band of about 1,200 bp could be observed in 47 E. coli isolates from cattle and the most prevalent band of about 2,850 bp could be observed in 32 isolates from water. Fifty isolates from water produced 39 unique profiles, while 50 isolates from cattle formed 30 single profiles. Moreover, six E. coli isolates from water had the same profiles as the isolates from cattle (Table 1), indicating the probability of the same origin.
