细菌L型是细菌变异而引起的细胞壁的缺陷型。L型有三种菌落〔林特夫,等.临床检验杂志 1987;5(3):130.〕,临床材料分离时常见的为G型,L型菌落,F型菌落较少见,而且难以返祖。我院从新生儿血培养中分离出一株F型金黄色葡萄球菌。介绍如下: 一、病例介绍:婴儿,7天,以呕吐、食少,全身皮肤进行性黄染住院。有羊水吸入青紫史。两肺呼吸音粗,脐部有脓性渗出物。WBC:12.3×10~9/L、N 74％,L 26％。X线见两肺纹理增生、内带片状阴影。拟诊为新生儿肺炎、新生儿黄疸、败血症。作血培养进一步检查。
Bacterial L-type is a variant of the bacteria caused by cell wall defects. There are three types of L-type colonies (Lin Toff, et al., 1987; 5 (3): 130). Clinical specimens are commonly found to be G-type and L-form colonies. F-type colonies are rare and difficult to return Zu. My hospital from neonatal blood culture isolated a Staphylococcus aureus. Introduced as follows: First, the case description: Baby, 7 days to vomit, eat less, systemic yellowish yellow dye hospitalization. Amniotic fluid inhalation of purple history. Breath sounds coarse lungs, umbilical purulent exudate. WBC: 12.3 × 10 ~ 9 / L, N 74%, L 26%. X-ray see the lungs hyperplasia, with flaky shadows. To be diagnosed as neonatal pneumonia, neonatal jaundice, sepsis. Blood culture for further examination.
