Abstract
In this study, the prevalence of nasopharyngeal carriage and the antimicrobial susceptibility profile of Haemophilus influenzae were investigated in children and adults with HIV infection in Jakarta, Indonesia. Thirty-four H. influenzae isolates were identified in the children (n=16/90; 18%) and adults (n=18/200; 9%) infected with HIV. All isolates were nontypeable H. influenzae and were less susceptible to ampicillin (62%) and trimethoprim/sulfamethoxazole (41%). In this study, the H. influenzae strains carried by patients infected with HIV were dominated by non-capsulated types.
