From: HIV infected adults do not have an excess of colonising bacteria in their large airways
Bacterial colonisation of the airways by HIV status. The figure shows the percentage of adults with bacterial colonisation of the oro-pharynx, posterior nasopharynx, trachea, right main bronchus and distal bronchi as measured using swabs (pharynx), tracheal washing and protected specimen brushing (right main bronchus and distal bronchi). Subjects are grouped according to HIV status and show no significant difference in percent colonisation at any site between HIV infected and non-HIV infected adults. The actual numbers of isolates are indicated over the bars and the bacteriological detail is included in the text.
