Abstract
Between December 1996 and October 1997, milk samples From a total of 145 co ws with coli mastitis were screened for the presence of verotoxin-producing E. coli (VTEC). VTEC were found in four (2.8 %) out of the 145 samples. Th e four isolated strains proved to be verotoxin (VT) 1-, VT2- or VT1- and VT 2-positive. However, no strain contained all three virulence factors tested . Further strain characterization was carried out by serotyping as well as by resistance pattern analysis.
