Respiratory tract infection caused by bacteria (non-Mycobacterium) and their antibiogram in HIV-positive patients.

Abstract. This study was undertaken from 1995-2000 to investigate the cause of respiratory tract infection among 481 patients with human immunodeficiency virus (HIV) at Siriraj Hospital, Bangkok, Thailand. The positive rate of bacterial pathogens was 38.46%. Pseudomonas aeruginosa appeared to be the most common pathogen (32.97%), followed by Staphylococcus aureus (18.92%), Klebsiella pneumoniae (10.81 %), Haemophilus influenzae (7.57%), and Acinetobacter baumannii (5.95%). P. aeruginosa was sensitive to netilmycin, amikacin, imipenem, meropenem, cefoperazone/sulbactam, piperacillin/tazobactam, and gentamicin (67-84%). S. aureus was sensitive to vancomycin and teicoplanin (100%).
