Nasopharyngeal carriage and antimicrobial susceptibility profile of Haemophilus influenzae among patients infected with HIV in Jakarta, Indonesia.

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.
