Bacterial pneumonia is better treated with cephalosporin antibiotics. Cephalosporins are broad-spectrum antibiotics with a wide antibacterial spectrum that can fight both gram-positive cocci and gram-negative bacilli. In clinical practice, second- and third-generation cephalosporins are mostly used to treat pneumonia, and antibiotics can also be selected based on the patient’s sputum culture and the results of drug sensitivity. If the patient is infected with drug-resistant bacteria or multiple complex bacterial infections, fourth-generation cephalosporin antibiotics can be used, which are not commonly used and are mostly used to select effective antibiotics for treatment after the patient obtains the drug sensitivity results. If it is Mycoplasma pneumoniae infection or Chlamydia infection cannot be treated with cephalosporin antibiotics, instead, it is better to choose macrolides like azithromycin, or quinolone antibiotics like levofloxacin or pazufloxacin.
