Pseudomonas aeruginosa was isolated from the sputum of 63 patients. In 34 the organism was a commensal, in 14 it was causing chronic suppuration, and in 10 had interfered with antibiotics directed against other organisms and was thus indirectly pathogenic. In five patients, all of whom died, the organism could have been acting as an acute pathogen. Attempts should be made to determine the nature of the organism's pathogenicity in a given patient and appropriate therapy withheld or administered accordingly.
从63例患者的痰液中分离出铜绿假单胞菌。其中34例该菌为共生菌,14例引起慢性化脓,10例干扰了针对其他病原体的抗生素治疗,因此具有间接致病性。在5例均死亡的患者中,该菌可能为急性病原体。应努力确定特定患者中该菌的致病性质,并据此决定是否暂缓或给予适当治疗。
