MST (Molecular Serotyping Tool): a Program for Computer-Assisted Molecular Identification of Escherichia coli and Shigella O Antigens▿

Escherichia coli and Shigella O antigens can be inferred using the rfb -restriction fragment length polymorphism (RFLP) molecular test. We present herein a dynamic programming algorithm-based software to compare the rfb -RFLP patterns of clinical isolates with those in a database containing the 171 previously published patterns corresponding to all known E. coli / Shigella O antigens.
