Bacteria testing. Hands holding a culture plate testing for the presence of Escherichia coli bacteria by looking at antibiotic resistance. The agar plate is coated with a solution prepared from a sample supplied by a patient. Discs of filter paper soaked in antibiotic are applied and the amount of bacterial growth is observed. The antibiotics are (clockwise from top) piperacillin,amoxycillin,trimethoprim,cefuroxime,ciprofloxacin and gentamicin. Clear areas around all antibiotic disks show that the bacterium is not resistant to any of them,which positively identifies E. coli. The technician wears nitrile gloves and a white coat to avoid contamination | |
