Table 5.
STEC were divided into six groups according to sequence typing (STs). G1: overlapping STs between 2010 and 2011, G2: STs found only among isolates from native cattle collected in 2010, G3: STs found only among isolates from dairy cattle obtained in 2010, G4: overlapping STs between native and dairy cattle in 2011, G5: STs discovered only among isolates from native cattle in 2011, G6: STs discovered only among isolates from dairy cattle in 2011. Sequence type of one STEC isolate obtained in 2010 could not be identified. *New alleles and STs.
