Deer Meat as the Source for a Sporadic Case of Escherichia coli O157:H7 Infection, Connecticut1
Figure. Pulsed-field gel electrophoresis of O157 isolates from the Connecticut child and the deer meat showing XbaI and BlnI-digested genomic DNA. Lanes 1, 5, and 9 are Escherichia coli G5244, a standard strain used to characterize molecular size; lanes 2 (XbaI) and 6 (BlnI) are digests from the child’s O157 isolate, lanes 3 (XbaI) and 7 (BlnI) are digests from the deer meat O157 isolate, and lanes 4 (XbaI) and 8 (BlnI) are digests from an unrelated O157 patient. Numbers at right are molecular sizes (in base pairs).
