Staphylococcus aureus is harboured in the nares of 20-30% of healthy people. However, it is also recognized as a pathogen in human disease and is a common cause of healthcare associated infections worldwide. The aim of this study was to determine the nasal carriage rate of both Staphylococus aureus and coagulase-negative staphylococci of 112 paediatric and adult ward patients of a public tertiary hospital in Iligan City, Philippines. Clinical samples were used to isolate, characterize and identify S. aureus and coagulase negative staphylococci using standard microbiological protocols. The screening for nasal carriage of S. aureus and CoNS revealed the presence of S. aureus in 84% of the patient volunteers and 34% had CoNS. It was further observed that the females of the study population harboured higher numbers of S. aureus and CoNS than the males. This trend of staphylococcal colonization was detected in both the paediatric and adult populace. Predisposing factors to staphylococcal colonization among the paediatric patients were assessed and it was observed that there was a significant association between staphylococcal colonization and antibiotic use (p=0.028). However, there was no identified variable that was found to be statistically association with the colonization of staphylococcal isolates amongst the adult patients. This study is one of the very few in the Philippines and the high prevalence of S. aureus nasal carriage rates highlights the significant need for regular S. aureus screening, interventions and decolonization strategies.
