Evidence of an infective environment was frequently found in infants weighing less than 1 500 g at birth. Bacterial cultures from multiple sites bore no correlation to pus cells in the gastric aspirate or to placental histology. Positive cultures of ear swabs correlated with mortality, as did placental infection. The presence of pus cells in the gastric aspirate was related to histological evidence of placental infection. The duration or rupture of membranes and the serum IgM levels were not significantly associated with other findings.
在出生时体重不足1500克的婴儿中，经常发现存在感染环境的证据。来自多个部位的细菌培养结果与胃吸出物中的脓细胞或胎盘组织学无关。耳拭子培养阳性与死亡率相关，胎盘感染也与死亡率相关。胃吸出物中脓细胞的存在与胎盘感染的组织学证据有关。胎膜破裂的持续时间和血清IgM水平与其他发现无显著相关性。
