摘要
[目地]分析影响肠道双歧杆菌水平的可疑因素,为维持婴儿肠道的双歧杆菌优势提供线索。[方法]采集152例进行食物过敏诊断试验的婴儿大,便,运用平板活菌计数培养法和PCR鉴定法计数大便双歧杆菌,其影响因素的分析采用Spearman等级相关、单因素和多元线形回归分析。[结果]配方奶喂养儿、食物过敏儿或引入其他食物的婴儿的大便双歧杆菌计数分别较母乳喂养儿、非食物过敏儿或未引入其他食物的婴儿的大便双歧杆菌计数显著降低,且婴儿喂养方式、是否食物过敏、有无其他食物的引入对婴儿肠道双歧杆菌数量的影响作用逐级减弱。[结论]母乳喂养、适时引入其它食物将有利于婴儿肠道双歧杆菌优势的维持和食物过敏的预防。
[:Objective] To ascertain some factors suspected to decrease the levels of the bifidobacterium, and to provide a clue of keeping the predominance of intestinal bifidobacterium. [Methods] 52 infants finished food allergy diagonostic test. The fecal bifidobacterium were quantitatively and qualitatively analyzed by adopting the conventional culturing in specific media and polymerase chain reaction assay. The suspicious risk factors of the bifidobacterium means were analyzed by Spearman rank correlation, Single factor, Multiple stepwise regression analysis. [Results] The counts of bifidobacterium were significantly lower in the infants by formula feeding , with food allergy, with introduction of other foods than those in the infants by breast milk feeding, without food allergy, without introduction of other foods (P〈0.001 ). The influences of the feeding pattern, the occurrence of food allergy and the introduction of other foods on the amounts of bifidobacterium were gradually decreased. However, our data did not demonstrate any correlations between the amounts of bifidobacterium and the sex of infants, age, birth weight, atopic family history, gestational age, maternal delivery patterns(P〉0.05). [Conclusions] The breast milk feeding pattern,introduction of other foods timely in infancy are helpful to keep the predominance of infant intestinal bifidobacterium and prevent the occurrence of food allergy.
