Objective To study the pathogens and drug resistance profiles of pulmonary infection in patients with AIDS. Methods The pathogens and their drug susceptibility of pulmonary infection diagnosed by fibrobronchescopy-induced brunchoalveolar lavage fluid (BAI.F) culture and/or transbronchial biopsy in 116 AIDS cases were analyzed. Results Monopathogenic infection in lungs were detected in 18 cases(15.5%) and mixed infection in 98 cases ( 84.5%). Of the 116 cases, bacteria were present in 91 patients, fungi in 62, tubercle bacillus in 49, pneumocystis jiroveci in 29, and cytomegalovirus in 11.Ninety-five bacterial strains were isolated from BALF, mainly including Streptococci (34), coagulase negative Staphylococcus (20), Klebsiella pneumoniae (10) and Escherichia (7). The isolated bacteria were resistant to β-lactam, macrolides, quinolones and aminoglycosides, of which were 14 methicillin-resistant Streptococci (MRS) strains and 12 extended spectrum β-lactamases (ESBL) strains. Sixty-eight fungal strains were isolated, including 36 Candida mycodermas, 19 Penicilliums, 6 Aspergilli and 5 Mold fungi;they were sensitive to amphotericin B but resistant to fluconazol (5.6% -50. 0% ) and itraconazole( 10. 5%-60. 0% ). Conclusion Pneumonia in AIDS patients are usually caused by multiple pathogens,predominantly consisting of multiresistant bacteria and fungi. Therefore, antibiotics should be rationally chosen according to drug susceptibility test.
