Prenatally, bacteria in the amniotic fluid and meconium, likely derived from the maternal microbiota, prime the fetal immune system to tolerate beneficial microbes postnatally. At birth, the neonate acquires its initial microbiota through the birth canal or environmental exposure, with breast milk delivering human milk oligosaccharides that selectively nourish beneficial bacteria, such as Lactobacillus and Bifidobacterium, fostering a protective gut microbiota. Meconium in the colon further supports this process by acting as a barrier against pathogens while promoting colonization by commensal microbes. These early microbial communities enhance intestinal barrier function through tight junction maturation, reduce permeability, and bolster immune defenses, mitigating infection risks. As infants transition to solid foods, microbial diversity increases, supporting intestinal villi development, nutrient absorption, and dietary adaptability. By approximately 3 years of age, the gut microbiota stabilizes, driving critical roles in digestion, vitamin synthesis, and inflammation regulation.

La aparición conjunta de secuestro pulmonar y malformación adenomatoidea quística se ha descrito en muy pocos casos, aproximadamente 40-60 pacientes desde el primer caso reportado en 1949. Secuestro pulmonar se define como tejido quístico pulmonar ectópico no funcionante, con vascularización arterial propia de origen sistémico.
