bPercentage (%) of total number of samples carrying ESBL
cPercentage (%) of the total n the total number of ESBL in each country umber of ESBL in each country belonging to a certain genotype
dPercentage (%) of TEM and SHV of the total number of ESBL in each country. However, note that a bla TEM and bla SHV genotype present in the same bacterial strain as another ESBL genotype could be bla TEM-1, bla TEM-2, or bla SHV-1 which are not considered true ESBL genotypes, but the original genes from which later genotype variants are derived from
