The blood culture results of patients of S. M. Nuova Hospital of Florence (Italy) have been examined in a period of nine years (1967-1976). We can attest from this results that in the last years of this period we have had an increase of the number of Enterobacteriaceae from blood culture. In the meanwhile we have had a decrease of positive results that is not due to an increase of the number of blood culture; in fact it has been doubled, but this decrease is mostly due to a larger number of examinated patients that to an increase of blood culture for each patient. Introduction in the routine of a diphasic culture system (Castañeda) commercially available has allowed contaminants' decrease. Antibiotic resistance of most important bacteria isolated in the last three years (1974-1976) were carry out.
对意大利佛罗伦萨圣玛丽亚诺瓦医院患者的血培养结果进行了为期九年（1967 - 1976年）的检查。从这些结果中我们可以证明，在这段时期的最后几年，血培养中肠杆菌科细菌的数量有所增加。与此同时，阳性结果有所减少，这并非由于血培养数量的增加；事实上，血培养数量已翻倍，但这种减少主要是由于接受检查的患者数量增加，而非每位患者血培养次数的增加。引入市售的双相培养系统（卡斯塔涅达法）用于常规培养，减少了污染。对过去三年（1974 - 1976年）分离出的最重要细菌的抗生素耐药性进行了检测。
