Staphylococcus aureus nasal carriage rates among children between one-to-five years in Barangay Pio Del Pilar, Makati City

ABSTRACT

Objective@#This study aims to determine the staphylococcal nasal carriage rates of children who are between one-to-five years old and residing in Botanical Gardens, Barangay Pio Del Pilar, Makati City. The following shall also be investigated: antibiotic resistance patterns of isolates, factors associated with S. aureus nasal carriage, and other pathologic organisms colonizing the anterior nares in this population. @*Methods@#Nasal swabs were taken from each subject and cultured after informed consent was obtained. Statistical analysis was performed to determine factors with significant association with nasal colonization. @*Results@#Ten (12.9%) out of 77 subjects were positive for S. aureus nasal colonization, one of which was oxacillin-resistant. Only the gross monthly income showed significant association with nasal carriage (p=0.03, OR = 0.59, 95% CI). Four subjects (5.1%) were carriers of S. pneumoniae. @*Conclusions@#The study shows a relatively low rate of Methicillin Sensitive S. aureus (MSSA) and Methicillin Resistant S. aureus (MRSA) nasal carriage. The MRSA isolate was sensitive to all other anti-staphylococcal drugs tested, similar to other studies on Community Acquired-MRSA (CA-MRSA). Local surveillance studies are essential in the control of CA-MRSA and in guiding local antibiotic policies for staphylococcal infections. Further studies on a bigger population are needed to determine rates, resistance patterns and risk factors associated with nasal colonization.
