Insights

This research spans 30 years, focusing on acellular pertussis vaccines and serogroup B meningococcal disease vaccines. Current work investigates protective immune responses to Bordetella pertussis infection.

Area of Science:

  • Microbiology
  • Vaccinology
  • Immunology

Background:

  • Nearly 30 years of research at Porton, initially at the Centre for Applied Microbiology and Research, then the Health Protection Agency.
  • Early work involved developing an acellular pertussis vaccine, including antigen characterization and pathogenesis studies.
  • Research shifted to serogroup B meningococcal disease, exploring vaccine potential of iron-regulated proteins and Neisseria lactamica.

Discussion:

  • The resurgence of pertussis highlights gaps in understanding protective immunity.
  • Focus shifted back to Bordetella pertussis due to evolving disease patterns.
  • Investigating immune responses to infection and disease is crucial for vaccine development.

Key Insights:

  • Development of an acellular pertussis vaccine incorporating fimbriae.
  • Exploration of iron-regulated proteins and Neisseria lactamica for meningococcal vaccines.
  • Identification of knowledge gaps in pertussis immunity.

Outlook:

  • Continued research into protective immune responses against Bordetella pertussis.
  • Addressing the challenges posed by the resurgence of pertussis.
  • Leveraging past research to inform future vaccine strategies for both pertussis and meningococcal diseases.

Bacterial Meningitis II: Pathophysiology01:26

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

Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...

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...
Viral Meningitis01:18

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...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Mechanism of Antibiotic Resistance in MRSA01:25

Mechanism of Antibiotic Resistance in MRSA

Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...
