The gut microbial community is known to influence the human health and disease state and is shaped by various factors since birth. It is now evident that understanding the alterations in these commensal microbes during crucial stages of life is of utmost importance to determine and predict the health status of an individual. To study the gut microbiota in two such vital stages, pregnancy and infancy, we analyzed gut microbial communities from 20 mother-infant dyads at different stages of pregnancy and early infancy. In total, we analyzed 80 fecal samples for profiling the gut microbial community using 16S rRNA gene-based sequencing. We observed no significant alterations in the gut bacterial diversity during pregnancy; however, significant alterations were observed during the period from birth to six months in infants, with a reduction in Staphylococcus and Enterococcus and an increase in Bifidobacterium and Streptococcus with a more stable microbial community at the age of six months.

Round-shaped structure usually located in the upper fundus of the UTERUS in early pregnancy. It comprises EMBRYO; AMNIOTIC FLUID; and YOLK SAC. It is visible in PRENATAL ULTRASONOGRAPHY by the fifth week of pregnancy. Its size is often used to determine and monitor GESTATIONAL AGE; FETAL GROWTH; and PREGNANCY COMPLICATIONS.
A disorder caused by hemizygous microdeletion of about 28 genes on chromosome 7q11.23, including the ELASTIN gene. Clinical manifestations include SUPRAVALVULAR AORTIC STENOSIS; MENTAL RETARDATION; elfin facies; impaired visuospatial constructive abilities; and transient HYPERCALCEMIA in infancy. The condition affects both sexes, with onset at birth or in early infancy.
A condition in infancy or early childhood due to an in-utero deficiency of THYROID HORMONES that can be caused by genetic or environmental factors, such as thyroid dysgenesis or HYPOTHYROIDISM in infants of mothers treated with THIOURACIL during pregnancy. Endemic cretinism is the result of iodine deficiency. Clinical symptoms include severe MENTAL RETARDATION, impaired skeletal development, short stature, and MYXEDEMA.
A neurobehavioral syndrome associated with bilateral medial temporal lobe dysfunction. Clinical manifestations include oral exploratory behavior; tactile exploratory behavior; hypersexuality; BULIMIA; MEMORY DISORDERS; placidity; and an inability to recognize objects or faces. This disorder may result from a variety of conditions, including CRANIOCEREBRAL TRAUMA; infections; ALZHEIMER DISEASE; PICK DISEASE OF THE BRAIN; and CEREBROVASCULAR DISORDERS.
Proteins produced by organs of the mother or the PLACENTA during PREGNANCY. These proteins may be pregnancy-specific (present only during pregnancy) or pregnancy-associated (present during pregnancy or under other conditions such as hormone therapy or certain malignancies.)
