Apr 16, 2024 · A colony with typical E. coli morphology and size was selected for Gram staining to observe whether it was a negative strain. Then pure colonies were identified as E. coli using an automated bacterial identification system (VITEK 2 Compact, Biomerieux, France) (Infante et al., 2021).
