Insights

The intestinal microbiome significantly impacts infectious diseases, influencing immune development, enteric infections, and antimicrobial resistance. Understanding this gut microbiome is crucial for infectious disease physicians in clinical practice.

Area of Science:

  • Microbiology
  • Immunology
  • Infectious Diseases

Background:

  • The intestinal microbiome's role in health and disease is increasingly recognized.
  • A paradigm shift is occurring in infectious disease understanding due to microbiome research.

Purpose of the Study:

  • To inform infectious disease physicians about the clinical relevance of the intestinal microbiome.
  • To review the pathophysiologic links between the microbiome and various infectious conditions.

Main Methods:

  • Systematic literature search of Medline using keywords: infectious diseases, microbiome, probiotics.
  • Review of relevant articles published up to 2017 using Rayyan software.

Main Results:

  • The intestinal microbiome influences early immune development.
  • It plays a role in enteric infections and in compromised host susceptibility.
  • Microbiome alterations are linked to antimicrobial resistance.

Conclusions:

  • The intestinal microbiome is integral to microbiology and pediatric/adult infectious diseases.
  • Clinicians can utilize microbiome concepts for improved patient care.
  • Established roles in specific diseases and at-risk populations highlight its significance.

Factors Affecting the Risk of Infection

The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

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.

Fungal Phylum Microsporidia

Microsporidia are a group of obligate intracellular fungi that were initially classified as protists but were later reclassified based on phylogenetic, molecular, and structural evidence linking them to the Chytridiomycota. These unicellular, non-motile organisms are highly specialized parasites that infect a wide range of animal hosts, including humans. They have evolved extensive genomic and metabolic reductions, making them highly dependent on their hosts for survival.Morphology and Genomic...

Anatomy of the Intestines01:23

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...

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.

Infection01:20

Infection

When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...
