Nocardia cyriacigeorgica infection in a patient with repeated fever and CD4+ T cell deficiency: A case report

Figure 1 Computerized tomography showed multiple patchy, nodular and strip high density shadows in both lungs. A: Showed multiple patchy, nodular and strip-shaped high-density shadows in the upper lobe of the right lung; B: Showed multiple patchy, nodular and strip-shaped high-density shadows in the upper lobe of the lower lobe of the left lung, multiple sputum thrombi in the bronchus of the lower lobe of the left lung.

Figure 2 Pathogenic examination. A: Positive acid-fast bifurcating filaments were observed in bronchoalveolar lavage fluid of the patient under oil microscope (×1000 magnification); B: Branching gram-positive rods were observed in bronchoalveolar lavage fluid of the patient under oil microscope (×1000 magnification); C: matrix-assisted laser desorption ionization-time of flight mass spectrometry confirm it was Nocardia cyriacigeorgica.
