一、病原菌的动向日本作者对过去10年所收治的161例菌血症进行分析,其病原菌以革兰氏阴性杆菌为压倒多数,占70%以上,其中又以大肠杆菌、产气杆菌、绿脓杆菌最多,灵杆菌、肠杆菌、嗜麦芽杆菌等也是相当多的。这些菌血症病例中,仅一种细菌引起者为多数,由二种细菌引起者有24例,占15%,由3种以上细菌引起者只见到1例。由多种细菌引起的菌血症,治疗时应注意,不能仅针对一种细菌进行治疗。由于中心静脉营养插管普及后,真菌性的菌血症增加了,此属内因性感染,与宿主的条件有重要关系。 First, the trend of pathogens Japanese authors over the past 10 years, 161 cases of bacteremia were analyzed, the pathogens to Gram-negative bacilli overwhelming majority, accounting for more than 70%, of which Escherichia coli, Aerobacter aerogenes, green Most of Pseudomonas, the spirit of bacteria, Enterobacteriaceae, such as bacillus is also quite a lot. Of these bacteremia cases, only one caused by bacteria was the majority, 24 cases were caused by two kinds of bacteria, accounting for 15%, and only one case was caused by three or more kinds of bacteria. Bacteremia caused by a variety of bacteria, treatment should pay attention to, can not be treated for only one kind of bacteria. Due to the popularity of central venous nutrition after catheterization, fungal bacteremia increased, this is an internal infection, and the conditions of the host has an important relationship.
