Antibiotics help treat a bacterial infection.


  • Blood and urine tests will show if you have an infection.
  • A sputum sample is collected in a cup when you cough. The sample is sent to a lab to be tested for the germ that is causing your infection.
  • Bronchoscopy is a procedure to look inside your airway and learn the cause of your airway or lung condition. A bronchoscope (thin tube with a light) is inserted into your mouth and moved down your throat to your airway. Tissue and fluid may be collected from your airway or lungs and sent to a lab for tests.
  • A chest x-ray may be used to look for signs of pneumonia (lung infection) that can occur with LD.


Without treatment, your lung problems may worsen. Your lungs may fill up with fluid and make it hard for you to breathe. The infection may spread to other parts of your body and cause damage to other organs, such as your heart and kidneys. This can be life-threatening.
