Nasal carriage of
has been associated with subsequent infection and transmission within the hospital and
community settings. This study was carried out to evaluate the carriage rates of
in a University student population and
describe risk factors associated with the carriage. Two-hundred and seventy-seven nasal samples were obtained from healthy volun
teer students and screened for
by standard microbiological techniques. Antibiotic susceptibility testing was conducted on
the bacterial isolates by the disk diffusion technique. A questionnaire was conducted with each student to acquire demographic and
risk factor information. One hundred and fifty-seven (56.7%) isolates were identified as
. Antibiotic resistance was highest
for cloxacillin (91%), ceftazidime (71%), cotrimoxazole (23%), erythromycin (20%) and oxacillin (16%). Risk factors such as hos
pitalization in the past 12 months, recent skin infection and participation in sports were significantly associated with carrier status.
High resistance to certain antibiotics observed in this study shows that nasal colonization could serve as a reservoir of antibiotic
resistant strains within the community.
