Cesarean delivery (c-section) is on the rise globally. C-section is generally preferred if complications prevail in a vaginal delivery. Some private institutions conduct it unnecessarily for economic gains. This has led to a severe risk to a child’s health. The neonate’s gut microbiota has been observed to be influenced by the mode of delivery. Lactobacilli and other bacteria are very vital for developing healthy gut flora. An attempt has been made to investigate the passage of lactic acid bacteria to the infant via delivery. The vaginal swabs of the mothers and fresh meconium samples of the newborns post-delivery were examined for the presence of lactobacilli through culture techniques. The present investigation revealed that c-section-delivered infants lacked these bacteria in comparison with vaginally delivered infants. Biochemical tests and 16S rRNA sequencing showed similarity with groups 1, 2, 3, and 5 of Enterococcus genus. Phylogenetic analysis revealed more than 98% similarity with several Enterococcus species. E. canintestini, E.rivorum, and E. dispar were transferred frequently from mother to infants born via vaginal delivery. The strains were submitted to the NCBI GenBank database under accession numbers KX830968–KX830982. The study supports the hypothesis of maternal-neonatal transmission of bacteria during delivery and also possibilities of isolating newer strains for probiotic use.

分娩过程中肠球菌菌株的母婴传播

剖腹产（剖腹产）在全球范围内呈上升趋势。如果阴道分娩出现并发症，通常首选剖腹产。一些私人机构为了经济利益而进行不必要的活动。这对儿童的健康造成了严重威胁。已经观察到新生儿的肠道微生物群受到分娩方式的影响。乳酸杆菌和其他细菌对于发展健康的肠道菌群非常重要。已经尝试研究乳酸菌通过分娩传播给婴儿。通过培养技术检查母亲的阴道拭子和分娩后新生儿的新鲜胎粪样本中是否存在乳酸杆菌。目前的调查显示，与阴道分娩的婴儿相比，剖腹产婴儿缺乏这些细菌。生化测试和 16S rRNA 测序显示与肠球菌属的第 1、2、3 和 5 组相似。系统发育分析显示与几种肠球菌属有 98% 以上的相似性。E. canintestini、E.rivorum 和 E. dispar 经常从母亲转移到通过阴道分娩出生的婴儿。菌株以登录号 KX830968–KX830982 提交给 NCBI GenBank 数据库。该研究支持在分娩过程中母婴传播细菌的假设，以及分离用于益生菌使用的新菌株的可能性。dispar 经常从母亲转移到通过阴道分娩出生的婴儿。菌株以登录号 KX830968–KX830982 提交给 NCBI GenBank 数据库。该研究支持在分娩过程中母婴传播细菌的假设，以及分离用于益生菌使用的新菌株的可能性。dispar 经常从母亲转移到通过阴道分娩出生的婴儿。菌株以登录号 KX830968–KX830982 提交给 NCBI GenBank 数据库。该研究支持在分娩过程中母婴传播细菌的假设，以及分离用于益生菌使用的新菌株的可能性。
