Infection

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...

Biological Methods for Microbial Control

Biological Methods for Microbial Control

Biological agents offer an effective means of controlling microbial growth by leveraging natural processes like predation, competition, and the secretion of antimicrobial substances.Predatory bacteria such as Bdellovibrio species target and kill pathogens like Salmonella and E. coli. They are widely used in poultry farms to control infections. Myxococcus species help combat plant-pathogenic fungi. These naturally occurring predators serve as eco-friendly alternatives to chemical pesticides and...

Neuroimmunology
Infectious Disease
Cellular Biology

Background:

Border-associated macrophages (BAMs) are strategically positioned at the brain's interface with the periphery.
Their role during central nervous system infections remains incompletely understood.

Purpose of the Study:

To investigate the dynamics, diversity, and cellular fate of murine BAMs during infection.
To elucidate the neuroprotective functions of BAMs in the context of infection.

Main Methods:

Utilized advanced techniques to track BAMs in murine models of infection.
Analyzed BAM populations for diversity and functional characteristics.

Main Results:

Characterized the dynamic changes in BAM populations during infection.
Identified distinct BAM subsets with specific roles.
Demonstrated a significant neuroprotective role for BAMs.

Conclusions:

BAMs exhibit dynamic and diverse responses to infection.
These cells play a crucial role in protecting the brain during infection.
