BACTERIAL SENSITIVITY TESTS Meaning and
Definition
-
Bacterial sensitivity tests, also known as antibiotic susceptibility tests or antimicrobial susceptibility tests, are laboratory procedures used to determine the effectiveness of antimicrobial drugs against specific bacteria. These tests are crucial in guiding healthcare professionals in selecting the most appropriate antibiotic treatment for patients with bacterial infections.
Bacterial sensitivity tests are typically performed using a pure culture of the bacteria isolated from the patient. The bacteria are exposed to different antibiotics or antimicrobial agents, and the growth or inhibition of the bacteria in their presence is measured. The results indicate the susceptibility or resistance of the bacteria to specific antibiotics.
There are several methods for conducting bacterial sensitivity tests, including disk diffusion, broth dilution, and gradient diffusion. In disk diffusion, paper disks containing a standardized amount of antibiotics are placed on an agar plate inoculated with bacteria. The presence or absence of a zone around each disk indicates the susceptibility or resistance of the bacteria to the antibiotic. Broth dilution involves exposing the bacteria to varying concentrations of antibiotics in liquid media, and the minimum inhibitory concentration (MIC) is determined. Gradient diffusion uses a strip containing a gradient of antibiotic concentrations, and the MIC can be determined by measuring the point at which bacterial growth is inhibited.
Bacterial sensitivity tests are important for proper antibiotic therapy, as they help prevent the inappropriate use of antibiotics, minimize the likelihood of drug resistance, and ensure effective treatment for bacterial infections.
