The Nasal Carriage of Staphylococcus aureus and its Antimicrobial Susceptibility Pattern in Secondary School Students in Kurdistan Region, Iraq
Staphylococcus aureus is a common commensal bacterium of the human body and a potential pathogen, causing public health hazards. Due to various virulent factors and growing antibiotic resistance, bacteria could cause various infections, ranging from minor skin infections to life-threating sepsis.
The present study aimed to evaluate the prevalence rate of S. aureus and determine its antimicrobial sensitivity profile in the secondary school students in Duhok City, Iraq.
Samples were collected from the anterior nares of 492 volunteers aged more than 16 years in different cities, including Akre, Amedye, Bardarash, and Duhok. Conventional laboratory tests were performed for the identification of the bacterial isolates. In addition, the antimicrobial sensitivity test was carried out in accordance with the Clinical and Laboratory Standards Institute (CLSI).
Out of 492 subjects, 185 cases (37.6%) were carriers of S. aureus, including 57/185 (30.8%) males. The oxacillin resistance rate was estimated at 41.08%, while the resistance rate against tetracycline, fusidic acid, ciprofloxacin, gentamicin, vancomycin, clindamycin and rifampicin was 27.02%, 19.46%, 9.19%, 8.65%, 7.56%, 3.78%, and 1.08%, respectively. All the isolates were susceptible to teicoplanin.
According to the results, the prevalence rate of S. aureus was high, and the species were more common in females. Therefore, further investigations are required to monitor the S. aureus antimicrobial profile and implement proper plans to manage the associated issues.
