Summary
The RegIIIβ protein influences gut bacteria, reducing vitamin B6 production and allowing Salmonella pathogen colonization. This highlights the gut microbiota
Area of Science:
- Microbiology
- Gut Microbiome Research
- Host-Pathogen Interactions
Background:
- The gut microbiota is crucial for host health, influencing vitamin synthesis and pathogen resistance.
- Alterations in gut microbial composition can lead to disease and increased susceptibility to infections.
Purpose of the Study:
- To investigate the role of RegIIIβ in modulating gut microbiota composition.
- To determine the effect of RegIIIβ on vitamin B6 production within the gut.
- To understand how RegIIIβ influences the colonization of Salmonella.
Main Methods:
- Utilized mouse models to study the impact of RegIIIβ on the gut environment.
- Analyzed changes in microbial community structure and function.
- Quantified vitamin B6 levels and Salmonella colonization.
Main Results:
- RegIIIβ significantly altered the composition of the gut microbiota.
- Vitamin B6 production was decreased in the presence of RegIIIβ.
- RegIIIβ promoted sustained colonization by Salmonella.
Conclusions:
- RegIIIβ acts as a key regulator of gut microbiota composition.
- Reduced vitamin B6 levels due to RegIIIβ may contribute to pathogen susceptibility.
- The findings provide insights into host-microbe interactions and disease pathogenesis.

Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

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.

01:26Factors Affecting the Risk of Infection
14.3K
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...

The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

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...
