The gut microbiota is a vast and intricate collection of microorganisms that have a substantial effect on human health. Historically, the gut microbiota was known as gut microflora.

The gut microbiota contributes to numerous bodily functions.

  • Obtaining energy from digested food and protecting against pathogens.
  • Immune function regulation
  • Enhancing the gut and intestinal biochemical barrier
  • Changes in the microbiota’s composition can have an effect on these functions.

Despite the presence of beneficial bacteria in the gut, pathogenic bacteria can enter the GI tract and cause infection. These infections include food poisoning and other gastrointestinal diseases that cause diarrhoea and vomiting.

What significance does the human microbiota have?

Microorganisms are indispensable to human life and perform a wide range of crucial functions. In fact, there are approximately ten times more bacterial cells than human cells in the digestive system.

• Autistic spectrum disorder
• Cancer
• Celiac disease
• Diabetes
• Eczema
• Heart disease
• Malnutrition
• Multiple sclerosis

Where can microbiota be found?

Microorganisms existed before humans. It is believed that the intestine is one of the most densely populated microbial habitats on Earth. Humans harbour additional microorganisms in their nose, mouth and throat, small intestine, lungs, vagina, and skin.

When does intestinal microbiota development begin?

Previously, it was believed that the human microbiome began colonising the gut at birth, but recent research suggests that commensal bacteria may be transmitted from mother to child across the placental barrier. The earliest bacteria to colonise infants may have originated in the microbiome of the mother’s mouth.

The mode of delivery in early life has a substantial effect on the gut flora. A vaginally delivered infant is initially colonised by the mother’s vaginal and intestinal microbiota. In contrast, the baby is first exposed to skin and hospital environment bacteria during a Caesarean section. Recent studies also suggest that bacteria can be transmitted from mother to child through the rectal canal.
