For pulmonary inflammation due to Klebsiella pneumoniae, a combination of treatments can be used to select antibiotics after the development of bacterial resistance. Its a gram-negative bacillus, and if resistant, respiratory secretions can be taken for drug sensitivity testing if necessary. For example, you can choose aminoglycosides, including gentamicin and tobramycin. Quinolones, such as ciprofloxacin, levofloxacin, lomefloxacin, and gatifloxacin, can also be used in combination. Third-generation cephalosporins, such as cefpiramide, cefoperazone sodium sulbactam, and even aminoglutethimide can be used in combination to treat lung infections caused by drug-resistant Klebsiella pneumoniae.
