Disadvantages
• The price of each strip is relatively high, compared with the price of disks
therefore, gradient tests are usually used to test only a few antibiotics per
strain
Automated Methods
• Automated and semi-automated devices for bacterial identification ID and AST
have significantly improved laboratory efficiency
• These instruments, using optical systems for measuring changes
- determine bacterial growth and antimicrobial susceptibility
- can produce results in a shorter time (6–12 h) than conventional manual
assessment
• These include
o Vitek II (Biomerieux)
o Phoenix (Becton-Dickinson
