antibiotic susceptibility studies


Antibiotic sensitivity testing is the measurement of the susceptibility of bacteria to antibiotics in vitro with the purpose of correlating these results with the clinical efficacy. Different techniques are available for this purpose:


minimum inhibitory concentration (MIC)

what is the Minimum Inhibitory Concentration (MIC)?: The lowest concentration of an antibiotic that prevents the visible growth of bacteria

what are the advantages of MIC?

  • Considers the concentration of antibiotic that must reach the target organ
  • Offers more accurate results
  • Allows to select the most suitable antibiotic

We have developed our own panels to provide you with the best service:

  • Antibiotics selected according to those registered for a specific species and process
  • Concentrations selected based on the cut-off points established by governmental institutions
  • We include antibiotics from other classes as an alternative for cases in which the bacteria are resistant to treatments with fewer restrictions on use

We perform custom studies to test your products against the bacteria of your choice, including those of our strain bank.



antibiogram (Kirby Bauer)

What is an antibiogram used for?: to assess the in vitro susceptibility rates of bacterial strains to a panel of antibiotics

Depending on the antibiotic, the diameter of zone of inhibition of bacterial growth and the clinical cut-off points, bacteria can be classified as sensitive, intermediate or resistant.
