医院内新生儿手掌菌群的调查

INVERSTIGATION OF FLORAS OF NEWBORNS IN HOSPITAL

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５７８％，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９７１％。共检细菌１６１株，其中革兰氏阳性细菌１３５株，占８３８％，包括金黄色葡萄球菌８７株，占５４０４％；表皮葡萄球菌８株，占４９６％；腐生葡萄球菌２株，占１２４％。革兰氏阴性细菌２６株，占１６１５％。包括大肠埃希氏菌１２株，占７４５％；阴沟肠杆菌３株，占１８６％；异型枸椽酸杆菌３株，占１８６％；丙二酸盐阴性枸椽酸杆菌６株，占３７３％。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９４２％和３７４％，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。

Inverstigation of the kinds and antibiotic susceptibilities of the floras from palms of 115 cases of nemborns with normal childbirth in obstetrical ward were done in this paper. The results wrer shown that the rates of infection for the palms of newborns were separately 57.8% in the group of 1-12 hours after born, 75% in the group of 12-24 hours after born and 97.1% in the group of 24 hours to 5 days after born. 161 strains of bacteria were isolated from the palms of newborns and in which 135 strains of were Gram-positives account for 83.8% and 26 strains were Gram-negatives account for 16.15%. The Gram-positives contained 87 strains of S. aureus account for 64.4%, 8 strains of S. epidermidis account for 5.92%, 2 strains of S. saprophyticus account for 1.48% and the Gram-negatives contained 12 strains of E. coli account for 7.45%, 3 strains of E.cloacae account for 1.86%, 3 strains of C.diversus account for 1.86%, 6 strains of C. amalonate account for 3.73%. ALl of the bacteria were more sensitive to Amikacin and Norfloxacin and were resistant to Penicillin, Ampicillin, Gentamicin, Zinacef and Ceftriaxone. The relationship between the infective rate and the methods of born and the sex was not obvious.
