Pathogens of the Human Central Nervous System- the Major Bacterial Pathogens

Area of Science:

• Neurology
• Infectious Diseases
• Immunology

Background:

• Pathogen infections frequently cause severe central nervous system (CNS) inflammation, such as encephalitis, meningitis, meningoencephalitis, and myelitis.
• These neurological disorders are initiated by diverse pathogens, including bacteria, viruses, fungi, and protozoan parasites.

Purpose of the Study:

• To summarize the various transmission routes and reactivation capabilities of pathogens that cause neurological inflammation.
• To highlight the increasing public health threat posed by expanding vector ranges and latent pathogen reactivation.

Main Methods:

• Review of scientific literature on pathogen-induced neurological inflammation.
• Analysis of transmission dynamics, including direct contact, vectors, and mother-to-child transmission.
• Examination of pathogen latency and reactivation triggers.

Main Results:

• Pathogens transmit through aerosols, droplets, ingestion, contact, vectors (e.g., mosquitoes, ticks), and animal interactions.
• Increasing vector ranges expand disease outbreaks to larger populations.
• Latent pathogens can reactivate due to aging, immune suppression, stress, or other infections, causing recurrent or chronic neurological disease.

Conclusions:

• Multiple pathogens can initiate severe or lethal CNS inflammation, either during initial infection or post-reactivation.
• Understanding transmission and reactivation is crucial for managing and preventing neurological inflammatory diseases.
