Antibiotics

Antibiotics are drugs that help people and animals combat bacterial illnesses. Antibiotics are antibacterial in nature. Antibiotic drugs are widely employed in the treatment and prevention of bacterial infections, and they are the most important type of antibacterial agent available. Antiprotozoal action is seen in a small number of antibiotics. Penicillin, ampicillin, cephalexin, ciprofloxacin, azithromycin, and erythromycin are among the most regularly used antibiotics. Protozoan infections are frequently treated with antibiotics. (Metronidazole can be used to treat a variety of parasitic infections.) Antibiotics can either kill or stop germs from growing.
