Insights

Probiotic supplementation can prevent serious gut issues like necrotizing enterocolitis (NEC) and late-onset sepsis (LOS) in premature infants. Early use supports healthy gut microbiome development and immune function in vulnerable newborns.

Area of Science:

  • Neonatal microbiome research
  • Pediatric gastroenterology
  • Immunology

Background:

  • Preterm infants exhibit altered gut microbiome development compared to term infants.
  • Microbiome dysbiosis is linked to clinical conditions such as necrotizing enterocolitis (NEC) and late-onset sepsis (LOS).
  • Probiotic supplementation is a potential strategy to modulate the preterm infant gut microbiome.

Approach:

  • This review synthesizes current literature on probiotic effects in preterm infants.
  • It explores proposed mechanisms of probiotic action on the gut microbiome, metabolome, and immune system.
  • Clinical considerations for optimal probiotic use are discussed.

Key Points:

  • Probiotics demonstrate efficacy in preventing NEC and LOS in preterm infants.
  • Emerging evidence supports probiotic benefits for preterm gut microbiome composition, metabolic activity, and immune modulation.
  • Understanding these effects is crucial for establishing best practices.

Conclusions:

  • Probiotic supplementation is a promising prophylactic intervention for preterm infants.
  • Further research is needed to elucidate optimal probiotic strains, dosages, and administration timing.
  • Evidence-based guidelines are essential for integrating probiotics into neonatal care protocols.

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Bacterial Flora of the Large Intestine01:29

Bacterial Flora of the Large Intestine

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.
