Insights
Antibiotics given during the first 1000 days can disrupt the developing gut microbiota, potentially leading to long-term health issues. This review explores antibiotic impacts on early-life gut establishment and associated dysbiosis.
Area of Science:
- Microbiology
- Developmental Biology
- Public Health
Background:
- The first 1000 days (conception to 2 years) are critical for establishing gut microbiota.
- Neonatal gut establishment is vulnerable to environmental factors.
- Antibiotics are common perinatal exposures impacting gut colonization.
Purpose of the Study:
- To review the impact of antibiotics on the developing intestinal microbiota.
- To discuss the role of antibiotics in dysbiosis and long-term health consequences.
Main Methods:
- Literature review focusing on perinatal and early-life antibiotic exposure.
- Analysis of studies on gut microbiota establishment and function.
- Examination of short- and long-term health outcomes linked to antibiotic-induced dysbiosis.
Main Results:
- Antibiotics significantly alter gut bacterial colonization patterns.
- Early-life antibiotic exposure can lead to persistent gut dysbiosis.
- Dysbiosis is associated with various negative health outcomes.
Conclusions:
- Antibiotic use during the critical first 1000 days poses risks to gut microbiota development.
- Interventions to mitigate antibiotic effects on the neonatal gut are crucial.
- Further research is needed to understand and manage long-term health consequences.
Abstract:
The developmental origin of health and disease highlights the importance of the period of the first 1000 days (from conception to 2 years) of life. In particular, the process of gut microbiota establishment occurs within this time window. Therefore, determinants interfering with neonatal gut establishment may disrupt its physiological functions and potentially lead to negative health outcomes. Antibiotics are among perinatal determinants that can directly or indirectly affect the pattern of gut bacterial colonization, with a long-lasting impact on intestinal ecosystem functions. In this review, we will examine the impact of antibiotics on the intestinal microbiota during the perinatal period and first years of life, a key interval for development of an individual's health capital. Further, we will discuss the role of antibiotics during short- and long-term dysbiosis and their associated health consequences.

Development of Immunocompetence
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
