Insights

Neisseria meningitidis causes severe infections and is a leading cause of death. This review covers meningococcal vaccines, including new developments targeting serotype B.

Area of Science:

  • Microbiology and Infectious Diseases
  • Vaccinology and Immunology

Background:

  • Neisseria meningitidis is an airborne Gram-negative pathogen causing life-threatening diseases.
  • It is categorized into 13 serotypes, with A, B, C, W-135, and Y being most clinically significant.
  • Meningococcal disease remains a global health concern, particularly during epidemic periods.

Purpose of the Study:

  • To review Neisseria meningitidis as a pathogen.
  • To explore recent literature on meningococcal vaccine development.
  • To highlight advancements in targeting all major serotypes, including the historically challenging serotype B.

Main Methods:

  • Literature review of recent scientific publications.
  • Analysis of current and developing meningococcal vaccines.
  • Focus on vaccine efficacy against different serotypes.

Main Results:

  • Existing vaccines effectively target serogroups A, C, W-135, and Y.
  • Serogroup B has historically presented a vaccination challenge.
  • Two new vaccines targeting serotype B are currently in development.

Conclusions:

  • Significant progress has been made in meningococcal vaccine development.
  • New vaccines are expected to broaden protection against N. meningitidis serotypes.
  • Continued research is crucial for controlling meningococcal disease globally.

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...
Vaccine Production01:23

Vaccine Production

Vaccine production involves a sequence of upstream and downstream processes to generate a safe and effective immunological product. It begins with cultivating microorganisms, such as viruses or bacteria, to obtain antigenic material. For viral vaccines, mammalian host cells are grown in bioreactors and subsequently infected with the target virus. The virus replicates within the host cells, which are lysed to release viral particles. This lysate is then clarified through filtration or...

Viral Meningitis

Viral meningitis is the most common form of meningitis and is often referred to as aseptic meningitis to indicate the absence of bacterial involvement. It is generally milder than bacterial meningitis, with symptoms including fever, headache, stiff neck, drowsiness, nausea, photophobia, and vomiting. Rarely, more severe manifestations or death may occur. Common causative agents include enteroviruses, particularly coxsackie A and B viruses and echoviruses, all members of the Enterovirus genus...
