cThe numbers of samples (denominator) indicated in the second column are all the positive cultures on which susceptibility testing was applicable. In the missing cases susceptibility testing was not performed on the prescribed antibiotics. Positive samples per hospital were presented as a fraction of total tested for susceptibility
