A CASE REPORT ON STENOTROPHOMONAS MALTOPHILIA

Abstract

Stenotrophomonas maltophilia is stated as the Gram-negative bacterium that is often resistant to multiple antibiotics. It is among the most common cause of community-acquired pneumonia in patients with underlying medical conditions, such as diabetes and hypertension. In this case, the patient’s pneumonia did not respond to empiric antibiotic treatment with ceftriaxone and azithromycin. However, his symptoms resolved after treatment with levofloxacin. This case report highlights the importance of considering S. maltophilia in the differential diagnosis of community-acquired pneumonia in patients with underlying medical conditions. Sputum culture with an antibiogram is essential for making the diagnosis and selecting appropriate antibiotic treatment.
