为了掌握MRSA在沈阳地区流行病学特点 ,采用血浆凝固抑制试验检测 87株MRSA血浆凝固酶型别。结果显示 ,87株MRSA中血浆凝固酶Ⅱ型有 47株 (5 4% ) ,Ⅳ型 2 4株 (2 7.5 % ) ,Ⅶ型 7株 ,Ⅲ型 7株。按菌株来源分析 ,门诊患者MRSA血浆凝固酶型别分布散乱 ,而病房医护人员和住院患者的MRSA血浆凝固酶型别以Ⅱ型居多 ,Ⅳ型次之 ,有明显的偏重集中现象。可见 ,沈阳地区城市大医院MRSA感染蔓延较为严重 ,流行的主要血浆凝固酶型别为Ⅱ和Ⅳ型
In order to grasp the epidemiological characteristics of MRSA in Shenyang, 87 strains of MRSA plasma coagulase were tested by plasma coagulation inhibition test. The results showed that there were 47 strains (54%), 24 strains (24.5%), 7 strains of type Ⅶ and 7 strains of type Ⅲ in 87 strains of MRSA. According to the origin of the strains, the type of MRSA plasma coagulant in outpatients was disorganized, whereas the types of MRSA plasma coagulase in ward medical staff and inpatients were mostly Type II, followed by Type IV, and obvious concentration bias was observed. Visible, Shenyang City Hospital MRSA infection is more serious, the prevalence of major coagulase type Ⅱ and type Ⅳ
