目的研究医院就诊患者感染葡萄球菌临床分布及耐药性分析。方法采用分离鉴定技术和K-B纸片扩散法,检测某医院就诊患者感染标本并对分离菌株进行药敏试验。结果 6个月内,从该医院就诊患者感染标本中共分离出葡萄球菌97株,其中耐甲氧西林金黄色葡萄球菌(MRSA)32株,耐甲氧西林凝固酶阴性葡萄球菌(MRCNS)39株。在检出的97株葡萄球菌中,有42.3%分离自痰标本,32.0%分离自血液,23.7%分离自分泌物。临床分离的葡萄球菌对青霉素和红霉素的耐药率分别为90%以上和45%以上。结论葡萄球菌主要引起呼吸道感染,检出率最高的是痰标本,耐药现象普遍,应加强合理使用抗菌药物的教育和管理。
Objective To study the clinical distribution and drug resistance of staphylococcus infected patients in hospital. Methods The isolation and identification technology and K-B disk diffusion method were used to detect the infected patients in a hospital and the susceptibility test of the isolated strains. Results A total of 97 staphylococci were isolated from infected patients in this hospital within 6 months. Among them, 32 were methicillin-resistant Staphylococcus aureus (MRSA), 39 were methicillin-resistant coagulase-negative staphylococci (MRCNS) . Of the 97 Staphylococci detected, 42.3% were isolated from sputum, 32.0% were isolated from blood and 23.7% were from secretions. Staphylococcus aureus clinical isolates of penicillin and erythromycin resistance rates were 90% and more than 45%. Conclusion Staphylococcus aureus is the main cause of respiratory tract infection. The highest detection rate is sputum samples. The drug resistance phenomenon is common and the education and management of antibacterial drugs should be strengthened.
