RESUMEN
In view of the dearth of information relating to antibiotic resistance in community- and hospital-acquired bacterial infections in Papua New Guinea (PNG), we carried out a prospective, hospital-based observational study of surgical patients between October 2008 and October 2009. In a sample of 115 patients (median age 30 years; 55% males) suspected of having a bloodstream infection, blood cultures were positive in 11 (10%) and a significant pathogen was isolated in 9 (8%). Staphylococcus aureus was isolated in 4 patients (44%) and 3 were methicillin resistant; all these isolates were considered community acquired because cultures were performed within 48 hours of admission. Of the remaining 5 isolates, 4 were Gram-negative organisms with at least intermediate resistance to chloramphenicol that were grown from blood taken > 48 hours post-admission and thus considered nosocomially acquired. These data suggest two distinct patterns of bacterial infection in PNG surgical inpatients that have implications for national antibiotic prescription guidelines.
