Abstract

ABSTRACT In vitro, lactoferrin (LF) strongly inhibits human cytomegalovirus (HCMV), which led us to hypothesize that in vivo HCMV might also be inhibited in secretions with high LF concentrations. In breast milk, high viral loads observed as high viral DNA titers tended to coincide with higher LF levels. However, the LF levels did not correlate to virus transmission to preterm infants. The viral load in the transmitting group was highest compared to the nontransmitting group. We conclude that viral load in breast milk is an important factor for transmission of the virus.

母乳中的病毒载量与人巨细胞病毒向早产儿的传播有关,但乳铁蛋白浓度无关
在体外实验中,乳铁蛋白(LF)对人巨细胞病毒(HCMV)有较强的抑制作用,因此我们推测高浓度乳铁蛋白的分泌物可能也会抑制人巨细胞病毒(HCMV)。在母乳中,高病毒载量观察到高病毒DNA滴度往往与高LF水平相吻合。然而,LF水平与病毒向早产儿传播无关。传染组的病毒载量高于非传染组。我们得出结论,母乳中的病毒载量是病毒传播的一个重要因素。
