“…Identical strains have been isolated from healthy cattle, young and adult animals, and diseased humans, favouring the hypothesis of animals as sources of contamination for humans. One cannot exclude the possibility that bovine and human strains of EHEC and VTEC strains belonging to the same serotype and pathotype could be grouped differently on the basis of their host specificity (Mainil 1999; Brown et al. 2001; Pradel et al.…”

“…Transmission to humans has been reported essentially via consumption of raw milk or cheese (Mainil 1999; Blanco et al. 2001; Brown et al. 2001; Blanco et al.…”

“…O157:H7 EHEC from deer has been associated with a limited number of human outbreaks. On the contrary, they do not appear to be an important source of contamination for domestic cattle, as their pulsotypes are different (Brown et al. 2001).…”

“…On the contrary, O157:H7 EHEC have been exceptionally associated with diarrhoea in young calves (Dean‐Nyström et al. 1998; Brown et al. 2001; Kang et al.…”
