目的了解新生儿感染血培养细菌的分布及对抗生素敏感和耐药情况。方法用改良Ｋ－Ｂ法对感染性疾病新生儿血培养出的细菌进行药敏试验。结果普通血培养２７８１份，细菌检出率为１３５２％，其中金黄色葡萄球菌占３４８４％；Ｌ型血培养４２３份，检出率为１６５５％，其中Ｌ金黄色葡萄球菌占７０００％，Ｌ表皮葡萄球菌占１８５７％。丁胺卡那霉素对金黄色葡萄球菌、表皮葡萄球菌、枯草杆菌、克雷伯杆菌及Ｌ金黄色葡萄球菌的敏感率分别为７９３８％、９０９１％、９２００％、７８９５％和９１８３％；头孢氨噻肟对金黄色葡萄球菌、表皮葡萄球菌及克雷伯杆菌的敏感率分别为６５６５％、５７１４％和６８４２％；先锋霉素Ⅴ对表皮葡萄球菌的敏感率为７６６２％，对克雷伯杆菌的耐药率为８９４７％；庆大霉素和红霉素对枯草杆菌的敏感率分别为８９３３％和７３３３％；新青霉素Ⅱ对克雷伯杆菌、枯草杆菌、Ｌ金黄色葡萄球菌及Ｌ表皮葡萄球菌的耐药率分别为１００００％、９３３３％、６７３５％和８４６２％；氨苄青霉素对枯草杆菌、表皮葡萄球菌和Ｌ表皮葡萄球菌的耐药率分别为８９３３％、７１４３％和７６９２％；青霉素对上述菌株耐药率均较高；复达? Objective To understand the distribution of neonatal bacterial cultures of blood and the sensitivity and resistance to antibiotics. Methods The K-B method was used to test the antibacterial activity of bacteria in the neonatal blood of infectious diseases. Results There were 2781 common blood cultures with the detection rate of 1352%, of which Staphylococcus aureus accounted for 3484%; 423 Ltype blood cultures were detected with a detection rate of 1655% Accounting for 70  00%, Staphylococcus epidermidis accounting for 18  57%. The susceptibilities of amikacin to Staphylococcus aureus, Staphylococcus epidermidis, Bacillus subtilis, Klebsiella pneumoniae and Staphylococcus aureus were 7938%, 9091%, 9200%, 78  95% and 9183% respectively. The sensitivity rates of cefotaxime to Staphylococcus aureus, Staphylococcus epidermidis and Klebsiella were 6565%, 5714% and 6842%, respectively. Ⅴ was 7662% against Staphylococcus epidermidis and 8947% against Klebsiella pneumoniae. The sensitivities of gentamycin and erythromycin to Bacillus subtilis were 8933% and 7333%. The rates of resistance to penicillin Ⅱ to Klebsiella, Bacillus subtilis, Staphylococcus aureus L and Staphylococcus epidermidis were 10000%, 9333%, 6735% and 8453, respectively 62% respectively. The resistance rates of ampicillin to Bacillus subtilis, Staphylococcus epidermidis and Staphylococcus epidermidis were 8933%, 7143% and 7692, respectively ; Penicillin-resistant strains of the above-mentioned higher rates; re up to?
