Table 2 The distribution of β-lactamase genes from the 177 ESBLs producing bacteria identified

From: Phenotypic and genotypic characteristics of ESBL and AmpC producing organisms associated with bacteraemia in Ho Chi Minh City, Vietnam

Gene E. coli Klebsiella spp. Enterobacter cloacae Salmonella cholerasuis Totala
bla CTX-M 157 9 1 1 168 (95%)
bla TEM 70 7 1 1 79 (45%)
bla OXA 33 2 1 36 (20%)
bla SHV 1 4 5 (3%)
Not detected 3 1 4 (2%)
  1. aThe proportion of bacterial species harbouring a particular ESBL gene is expressed as a percentage of the total bacteria possessing an ESBL phenotype (n = 177)
