Lj. Allison et al., Characterization of a recurrent clonal type of Escherichia coli O157 : H7 causing major outbreaks of infection in Scotland, J CLIN MICR, 38(4), 2000, pp. 1632-1635
A particular recurrent clonal type of Escherichia coli O157 has been isolat
ed from multiple clinical, veterinary, food, and environmental sources thro
ughout Scotland since 1989. Significant genotypic variation was detected am
ong isolates from distinct outbreaks, with the presence or absence of singl
e fragments being sufficient to delineate outbreak groups within the clonal
type.
