葡萄球菌烫伤样皮肤综合征的诊断和治疗

目的了解小儿葡萄球菌烫伤样皮肤综合征（SSSS）的临床特点及治疗措施.方法对2001年6月-2004年8月收治的6例葡萄球菌烫伤样皮肤综合征的临床表现和实验室检查及诊疗过程进行分析.结果及时、合理应用有效抗生素及3%的硼酸湿敷和莫匹多星软膏外涂均痊愈.结论葡萄球菌烫伤样皮肤综合征好发于5岁以下儿童,皮损主要由毒血症所致,早期采用足量有效的抗生素是治疗成功的关键.     

Staphylococcal food poisoning and botulism

Staphylococcal food poisoning and botulism are caused by the ingestion of food containing exotoxins. Outbreaks of both are still a problem in many countries. This paper attempts to summarize information relating to these illnesses, together with advice on how their incidence may be reduced, or better still prevented.     

Staphylococcal suppurative mesenteric lymphadenitis.

Two young adult males presenting with suppurative mesenteric lymphadenitis, caused by coagulase positive staphylococcus, with unusual clinical findings are reported. Pre-operative and operative differential diagnosis and management are discussed. Previous publications are briefly reviewed. The condition is extremely rare in adults and the pathogenesis is not well understood.     

葡萄球菌DNA的原生质体转化

用三株金黄色葡萄球菌多剂抗生素耐药菌株80022,82022和82062的质粒DNA和总DMA,分别对受体菌金黄色葡萄球菌RN1304(Y-1)的原生质体进行转化试验。平衡期初期的受体菌用溶菌酶和溶葡萄球菌素处理,所获得的原生质体与质粒DNA混合,以PEG诱导,涂布于含药的双层DM_3再生培养基上,即可获得Tc~r或Cm~r转化子。转化率为10~2—10~3转化子/μg DNA。
