Klebsiella pneumonia: Your recent pneumonia was probably caused by Klebsiella pneumoniae, which causes destructive changes to lungs via inflammation and hemorrhage with cell death (necrosis) that sometimes produces a thick, bloody, mucoid sputum (currant jelly sputum). The bacteria is a Gram-negative, encapsulated, facultative anaerobic, bacterium. Evaluation by your physician is needed for persistent symptoms.
