Isolates with a CN prefix originated from the Burroughs-Wellcome collection, which included a number of type B isolates typically collected from diseased animals (usually lambs) during the 1930s to 1960s. Except as otherwise indicated, the geographical and disease origins of the isolates are unknown except that Bar2 was obtained from an Australian sheep and NCTC3110 is a vaccine production strain isolated in Kenya.
Originated from the United Kingdom.
The etx and cpb genes of NCTC3110 and CN677 are located on a 65-kb plasmid different from their 65-kb plasmid carrying the cpb and tpeL genes.
