OBJECTIVE
To determine rate of nasal colonization in Patients suffering from bacteraemia caused by methicillin resistant Staphylococcus aureus.
METHODS
This descriptive cross sectional study was carried out in a tertiary ca re, University Teaching Hospital (Shaikh Zayed Hospital, Lahore) from October 2010 to August 2011. Nasal swabs were taken from patients suffering from MRSA bacteraemia and were plated on mannitol salt agar plates to isolate Staphylococcus aureus (S. aureus) which were then tested for oxacillin susceptibility.
RESULTS
Nasal colonization was present in 52.5% of patients suffering from MRSA bacteraemia.
CONCLUSION
Nasal colonization rates with MRSA were high among patients suffering from MRSA bacteraemia especially in those undergoing dialysis or surgical procedures. Therefore, screening and nasal decolonization should be practiced in hospitals.
目的
确定耐甲氧西林金黄色葡萄球菌（MRSA）菌血症患者鼻腔定植率。
方法
这是 2010 年 10 月至 2011 年 8 月在一所三级保健、教学医院（拉合尔谢赫扎耶德医院）进行的描述性横断面研究。从 MRSA 菌血症患者中采集鼻腔拭子，并将其接种在甘露醇盐琼脂平板上以分离金黄色葡萄球菌（S. aureus），然后对其进行苯唑西林药敏试验。
结果
MRSA 菌血症患者中有 52.5%存在鼻腔定植。
结论
MRSA 菌血症患者中，MRSA 鼻腔定植率较高，尤其是在接受透析或手术治疗的患者中。因此，医院应进行筛查和鼻腔去定植。
