Staphylococcus aureus is an important microorganism which is associated with infections in the hospital setting. It is spread mainly through contaminated hands of the healthcare worker or through the underlying colonization of this microorganism in the nasal cavity of the healthcare worker. Apart from the healthcare worker, medical and dental students also can be source of the transmission because they are also engaged with the patients during their training period. The objective of this study was to determine the prevalence and risk of S. aureus colonization among dental students. Cross sectional study was conducted in the month of May 2014 involving a total of 205 dental students (104 pre-clinical years and 101 clinical years) from School of Dental Sciences, Universiti Sains Malaysia. The questionnaires were distributed and nasal swabs were collected. A total of 205 dental students participated in this study which comprises 50.7% pre-clinical year and 49.3% clinical year students. Their age ranged from 20 to 26 years old, with a mean (standard deviation) of 22.29 (1.73) years. The male to female ratio was 1:2.5. Eighteen percent of dental students had S. aureus colonized in their nasal cavity. No colonization of Methicillin resistant S. aureus strain was found in their nasal cavity. A carriage of S. aureus was significantly associated with the presence of health care worker among their family member. Healthcare worker may acquire S. aureus from the hospital, colonized in their nasal cavity and spread it to other family members via inhalation and close contact, however further study on this area is recommended to find out their relationship. S. aureus carrier among dental students worth screening to look whether the carry resistant strain i.e. MRSA to prevent spread to other patients. This is because they also involved in the clinical management during their clinical year study.
金黄色葡萄球菌是一种重要的微生物，与医院环境中的感染有关。它主要通过医护人员被污染的手传播，或通过医护人员鼻腔中这种微生物的潜在定植传播。除了医护人员外，医学和牙科学生也可能是传播源，因为他们在培训期间也会接触患者。本研究的目的是确定牙科学生中金黄色葡萄球菌定植的患病率和风险。2014年5月进行了横断面研究，涉及马来西亚理科大学牙科学院的205名牙科学生（104名临床前学生和101名临床学生）。发放了问卷并收集了鼻拭子。共有205名牙科学生参与了本研究，其中临床前学生占50.7%，临床学生占49.3%。他们的年龄在20至26岁之间，平均（标准差）为22.29（1.73）岁。男女比例为1:2.5。18%的牙科学生鼻腔中定植有金黄色葡萄球菌。在他们的鼻腔中未发现耐甲氧西林金黄色葡萄球菌菌株的定植。金黄色葡萄球菌的携带与家庭成员中有医护人员显著相关。医护人员可能从医院感染金黄色葡萄球菌，定植在鼻腔中并通过吸入和密切接触传播给其他家庭成员，然而建议对该领域进行进一步研究以查明它们之间的关系。牙科学生中的金黄色葡萄球菌携带者值得筛查，以查看是否携带耐药菌株即耐甲氧西林金黄色葡萄球菌，以防止传播给其他患者。这是因为他们在临床学年学习期间也参与临床管理。
