Beta-lactam antibiotics, such as penicillins and cephalosporins, fight infection by inhibiting development of the causative bacteria.
A particular class of antimicrobial agent that works against bacteria is an antibiotic. Antibiotic drugs are frequently employed in the treatment and prevention of bacterial infections because they are the most effective type of antibacterial agent for doing so. Bacteria may be killed or have their growth suppressed.
Staph, Strep, or E. coli infections are particularly treated with antibiotics, which either kill the bacteria (bactericidal) or prevent it from growing and reproducing (bacteriostatic). Antibiotics are ineffective against viral infections.
Overuse of antibiotics has been a significant clinical problem, and exposure to antibiotics is associated with changes in gut microbiota, which have been linked to increased risk of several chronic diseases, including cancer and cardiovascular disease.
