Antibiotic treatments are used to treat bacterial infections. They function by killing bacteria or inhibiting their growth. Antibiotics are classified into several types based on their mechanism of action, such as beta-lactams (e.g., penicillin), macrolides (e.g., erythromycin), and fluoroquinolones (e.g., ciprofloxacin). The appropriate use of antibiotics is essential to avoid the development of antibiotic resistance, a significant public health concern.
