甲氧苯青霉素抵抗的金黄色葡萄球菌发生率迅速提高

 
根据一项最新研究，甲氧苯青霉素抵抗的金黄色葡萄球菌(MRSA)已经成为皮肤和软组织感染最常见的原因，当皮肤感染被切开和引流之后，将急诊科医生带回了无青霉素的年代。

加州大学洛山矶医学中心(OVMC-UCLA, Sylmar, CA, USA)的Olive View在2004年对11所大城市进行了MRSA的前瞻性研究。来自422例在各个医院的成年患者接受了标准治疗，发现金黄色葡萄球菌的患者被送往疾病预防控制中心(CDC, Atlanta, GA, USA)接受进一步鉴定。超过75%的接受治疗的皮肤和软组织感染发现有金黄色葡萄球菌，59%都是甲氧苯青霉素抵抗。而2000年之前MRSA在皮肤和软组织并不是常见原因。根据地区不同在3%左右。
 
Methicillin-Resistant Infections Spread Like Wildfire
 
Methicillin-resistant Staphylococcus aureus (MRSA) has become the most common cause of skin and soft tissue infections, taking emergency room doctors back to the pre-penicillin days, when skin infections were lanced and drained, according to a new study.

Researchers from the Olive View-University of California Los Angeles Medical Center (OVMC-UCLA, Sylmar, CA, USA) prospectively looked at MRSA infections at 11 metropolitan centers in 2004. Specimens from 422 adult patients treated were cultured at each hospital using standard methods, and those found to be S aureus were sent to the Centers for Disease Control and Prevention (CDC, Atlanta, GA, USA) for further characterization. More than 75% of all skin and soft tissue infections treated were found to be colonized with S aureus, and 59% overall were methicillin-resistant. By comparison, MRSA was an uncommon cause of skin and soft tissue infections prior to 2000, hovering around 3%, depending on geographic location.
