Culture and Sensitivity

relationship of culture and sensitivity test

The only reliable way this can be done is a culture and sensitivity test. In modern laboratories, bacteria are usually identified by characterization of the genome. Antibiotic sensitivity or antibiotic susceptibility is the susceptibility of bacteria to antibiotics. Testing for antibiotic sensitivity is often done by the Kirby-Bauer method. but the correlation of in vitro to in vivo sensitivity is often high enough for the test looks at the sample under the microscope, and tries to culture the bacteria. Jan 26, Sensitivity analysis determines the effectiveness of antibiotics against (germs) such as bacteria that have been isolated from cultures.

To find out what these test are and what they mean Read and follow the links below What is the goal of testing?

The goal of antimicrobial susceptibility testing is to predict the in vivo success or failure of antibiotic therapy. Tests are performed in vitroand measure the growth response of an isolated organism to a particular drug or drugs.

The tests are performed under standardized conditions so that the results are reproducible. The test results should be used to guide antibiotic choice.

The results of antimicrobial susceptibility testing should be combined with clinical information and experience when selecting the most appropriate antibiotic for your patient. What is the output from antimicrobial susceptibility testing?

Antibiotic sensitivity - Wikipedia

The raw data are either in the form of a zone size or MIC. CLSI has published interpretation criteria for these tests, which has come from extensive testing and clinical correlation. How are the results reported? Once the bacterial cultures have been grown and tested with antibiotics, your doctor can analyze the results.

Cultures and Sensitivity Tests

These results can help determine the best antibiotic to treat your infection. You will likely have to take a higher dosage and for a longer time period If you are taking a drug from the intermediate group. You may also experience medication side effects.

Your doctor will decide which drug is best if several antibiotics are shown to be effective in killing the microorganism causing your infection. This combination of drugs is meant to work together to fight the bacteria.

  • Culture and Sensitivity
  • Sensitivity analysis

Drugs in this category can be more expensive and may have to be given intravenously through a needle in your vein. You will also likely have to take the combination of drugs for an extended time period.

Antibiotic sensitivity

Susceptibility testing may be used to figure out which antibiotic or combination of antibiotics will be most effective in treating the different types of bacteria causing the infection.

The Takeaway It is possible for bacteria and other pathogens to mutate.

Antibiotics that work today may not work six months from now. Sensitivity tests are extremely important and useful tools, especially if you have an infection caused by bacteria that has become resistant to some treatments.
