I-CeuI mapping of S. paratyphi C RKS4594. (A) PFGE separation of I-CeuI cleaved genomic DNA. See more detailed description in the text about complete and partial cleavages of the genomic DNA with I-CeuI. (B) I-CeuI cleavage map of the RKS4594 genome based on (A). The genome is circular; here it is shown as a linear map for the convenience of illustrating the mapping procedure. Only parts of fragment A (2512 kb) are shown at the ends of the linear map. The remaining 6 fragments are drawn to scale.
