Antibiotics are important for fighting bacterial infections, but using them too much or incorrectly can lead to antibiotic resistance. This means that bacteria can survive even when antibiotics are used. Antibiotic resistance is a big problem in many countries, especially in places where there are not enough resources to test which antibiotics will work best. To prevent antibiotic resistance, it's important to wash hands regularly, avoid self-medicating, and only use antibiotics when necessary. Testing for antibiotic susceptibility can help doctors choose the right treatment and reduce resistance. It's crucial to take steps to control antibiotic resistance to protect public health.
