Figure 2From: Extended spectrum β-lactamase-producing Escherichia coli forms filaments as an initial response to cefotaxime treatment Cell morphology of MG1655/CTX-M-1 and MG1655/IncI1/CTX-M-1 cultured with and without cefotaxime. Pictures are taken in early exponential phase. (A) MG1655/IncI1/CTX-M-1 cultured without cefotaxime, (B) MG1655/CTX-M-1 cultured with 32 mg/L cefotaxime, (C) MG1655/CTX-M-1 cultured with 2 mg/L cefotaxime and (D) MG1655/IncI1/CTX-M-1 cultured with 16 mg/L cefotaxime. MG1655/CTX-M-1 and MG1655/IncI1/CTX-M-1 were grown in MH-2 broth with and without cefotaxime and pictures were taken with a Zeiss microscope.Back to article page
