Resistance can be read if:
The five smaller sections of the Flexicult test each contain a different antibiotic
- *Cephalothin (16 mg/L)
- Ciprofloxacin (0.75 mg/L)
- Amoxicillin/Clavulanate (16/8 mg/L)
- Nitrofurantoin (64 mg/L) (Darker colour)
- Trimethoprim (3 mg/L)
The sections are numbered on the bottom of the test
(*Cephalothin is used to predict susceptibility to other first generation Cephalosporin such as cefalexin)
After
overnight incubation, bacteria will grow in the antibiotic
compartments if the bacteria are resistant (R) to the antibiotic in
question. Antibiotic sensitive (or susceptible) (S) bacteria are
inhibited by the antibiotic concentration and so will not grow in the
relevant bacterial compartment, i.e. they will not become colonies.
