本文对115例产科分娩的正常新生儿手掌细菌菌群的种类、分布及其药物敏感性进行了调查。结果表明,出生1~12小时的新生儿感染率为578%,12~24小时的新生儿感染率为75%,24小时~5天的新生儿感染率为971%。共检细菌161株,其中革兰氏阳性细菌135株,占838%,包括金黄色葡萄球菌87株,占5404%;表皮葡萄球菌8株,占496%;腐生葡萄球菌2株,占124%。革兰氏阴性细菌26株,占1615%。包括大肠埃希氏菌12株,占745%;阴沟肠杆菌3株,占186%;异型枸椽酸杆菌3株,占186%;丙二酸盐阴性枸椽酸杆菌6株,占373%。所检出的细菌对丁胺卡那霉素和氟哌酸敏感率较高,分别为942%和374%,对青霉素、氨苄青霉素、庆大霉素、西力欣、头孢三嗪均耐药。生产方式和性别与感染率无显著相关性。
In this paper, 115 cases of obstetric birth of normal neonates of the bacterial flora of the species, distribution and drug susceptibility were investigated. The results showed that the incidence of neonatal infection was 578% at 1 ~ 12 hours after birth, 75% at 12 ~ 24 hours, and 971% at 24 hours ~ 5 days. A total of 161 strains of bacteria were examined, of which 135 Gram-positive bacteria accounted for 83.8%, including 87 strains of Staphylococcus aureus (5404%), 8 strains of Staphylococcus epidermidis (496%), Staphylococcus saprophyticus 2 strains, accounting for 1 24%. Gram-negative bacteria 26, accounting for 16.15%. Including 12 strains of Escherichia coli, accounting for 745%; 3 strains of Enterobacter cloacae, accounting for 186%; 3 strains of special-shaped citric acid bacteria, accounting for 186%; malonate-negative Citrobacter 6 strains, accounting for 373%. The detected bacteria were more sensitive to amikacin and norfloxacin, which were 942% and 374%, respectively, which were sensitive to penicillin, ampicillin, gentamicin, celexin, cefotaxime All azine are resistant. There was no significant correlation between the mode of production and sex and infection rate.
