Table 3 Molecular Characterization of ESBL & AmpC β-lactamases in Enterobacteriaceae isolated (N = 88) from 27 randomly selected neonates

From: Community acquisition of β-lactamase producing Enterobacteriaceae in neonatal gut

E-A- 66 PCR not performed for strains with cefotaxime, ceftazimime zone diameter ≥ 28 and ≥ 23 respectively and phenotypic test negative for ESBL and AmpC16
  1. Note: Sequencing results *Tem 136, Tem 149; **SHV28. E = ESBL, A = AmpC, - = Negative, + = Positive.
  2. #ESBL and AMPc genes were mainly isolated in E.coli except one Klebsiella pneumoniae having both CTX-M as well as MOX gene.
  3. ## One Citrobacter showed the presence of DHA gene.
