Antibiotic testing is a laboratory procedure used to determine the effectiveness of antibiotics against specific bacteria. This process helps healthcare providers choose the most appropriate antibiotic for treating infections. Common methods include the disk diffusion method and broth microdilution, which assess how well an antibiotic can inhibit bacterial growth. In antibiotic testing, bacteria are exposed to various antibiotics, and their growth is monitored. The results indicate whether the bacteria are susceptible, intermediate, or resistant to the tested antibiotics. This information is crucial for guiding treatment decisions and combating antibiotic resistance, a growing global health concern.
