bRAPD–AFLP, Random Amplification of Polymorphic DNA–Amplified Fragment Length Polymorphism. Results obtained with the two genotyping techniques were always consistent with each other.
cIn these wards isolates of cluster A were also detected.
dIn this ward isolates of clusters A and B were also detected.
eGenotypes F to K included a number of isolates ranging from 1 to 7.
