Insights

Functional genomics studies reveal how Neisseria meningitidis (meningococcus) adapts to human environments. These findings identify potential virulence factors and vaccine candidates for controlling this pathogen.

Area of Science:

  • Microbiology
  • Genomics
  • Pathogenesis

Background:

  • Neisseria meningitidis is a significant global cause of septicemia and meningitis.
  • Understanding its adaptation to human niches is crucial for combating infection.

Purpose of the Study:

  • To investigate the adaptive strategies of N. meningitidis using functional genomics.
  • To identify novel virulence factors and vaccine candidates.

Main Methods:

  • DNA microarrays to analyze transcriptome changes in vitro and ex vivo.
  • Mutagenesis studies to identify genes essential for colonization and infection.
  • Genomic analysis for vaccine candidate discovery.

Main Results:

  • Transcriptome alterations observed upon interaction with human cells, serum, and blood.
  • Identification of genes critical for N. meningitidis colonization and systemic infection.
  • Discovery of potential vaccine candidates through genomic analysis.

Conclusions:

  • Functional genomics provides insights into N. meningitidis biology and pathogenesis.
  • These approaches facilitate the identification of new virulence factors and vaccine targets.

Bacterial Meningitis II: Pathophysiology

Bacterial meningitis typically begins when pathogens such as Neisseria meningitidis and Streptococcus pneumoniae colonize the nasopharynx and invade the bloodstream. This process is facilitated by bacterial virulence factors, such as polysaccharide capsules, which resist phagocytosis and complement-mediated killing. Less commonly, bacteria reach the central nervous system via contiguous spread from infections like otitis media or sinusitis, through congenital or acquired dural defects, or...

Bacterial Meningitis I: Introduction

Bacterial meningitis is a severe, life-threatening inflammation of the meninges, particularly the pia mater and arachnoid mater, affecting the subarachnoid space, ventricles, and cerebrospinal fluid (CSF). If untreated, it can lead to significant neurological complications or death.Causative AgentsCommon pathogens vary with age and immune status. In adults, major organisms include Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae. Streptococcus agalactiae (group B...
Evolution of Microbial Genome01:08

Evolution of Microbial Genome

Microbial genome evolution is a highly dynamic process shaped by continual gene gain and loss across species and strains. This genomic flexibility allows microorganisms to adapt rapidly to environmental pressures and interactions with other organisms. Central to understanding this diversity is the distinction between the core and pan genomes.The core genome comprises the genes shared by all sampled strains of a species, representing essential functions needed for fundamental cellular processes.
Human Virome01:26

Human Virome

The human body harbors a vast and diverse viral community known as the human virome. The virome includes bacteriophages that infect bacteria, and eukaryotic viruses that infect human cells. Transient dietary and environmental viruses also contribute to this dynamic ecosystem. Estimates suggest the human body may contain on the order of 10¹³ viral particles, though abundance varies widely by body site and detection method.Comprehensive characterization of the virome has become possible only with...
