本文从三个不同的研究机构近来的研究,证实婴儿出生后24～72小时由溶脲脲原体在呼吸道的定居及极低体重儿慢性肺部疾病(CLD)的发生之间存在着密切关系,但并未证实溶脲脲原体即是极低体重儿CLD和死亡的唯一原因。低体重婴儿对溶脲脲原体感染敏感性的增加可能是缺少一种或多种肺防御机能。此外,对氧需求增加可能也是易发感染的因素。 This article from a recent study of three different research institutes confirms that there is a close relationship between the infant’s colonization of the respiratory tract 24 hours to 72 hours after birth and the occurrence of CLD in the respiratory tract of very low birth weight children , But did not confirm that the sole cause of CLU and death in Ureaplasma urealyticum, which is very low birth weight children. The increased susceptibility of low-birth-weight infants to Ureaplasma urealyticum may be due to a lack of one or more lung defense functions. In addition, the increased demand for oxygen may also be a predisposing factor.
