Insights

Bacterial meningitis in Korean children was most commonly caused by Streptococcus agalactiae, Streptococcus pneumoniae, and Haemophilus influenzae. Continued surveillance is needed to refine prevention strategies for these key pathogens.

Area of Science:

  • * Pediatrics
  • * Infectious Diseases
  • * Epidemiology

Background:

  • * Bacterial meningitis is a significant cause of childhood illness and death.
  • * Effective vaccines exist for some common bacterial causes, yet incidence remains a concern.
  • * Data on bacterial meningitis etiology in Korea requires updated analysis.

Purpose of the Study:

  • * To analyze trends in bacterial meningitis cases in Korea between 1996 and 2005.
  • * To identify the primary bacterial pathogens responsible for meningitis across different age groups.
  • * To assess the case fatality rate and inform preventive strategies.

Main Methods:

  • * Retrospective analysis of hospitalized, bacteria-proven meningitis cases.
  • * Data collected from 17 university hospitals nationwide.
  • * Cases analyzed for demographic information and causative bacterial agents.

Main Results:

  • * A total of 402 bacterial meningitis cases were identified.
  • * Streptococcus agalactiae (24.6%) was the most frequent pathogen overall, particularly in neonates.
  • * Streptococcus pneumoniae (22.6%) and Haemophilus influenzae (16.7%) were also significant contributors, with S. pneumoniae being dominant in non-neonatal cases.

Conclusions:

  • * Streptococcus agalactiae, Streptococcus pneumoniae, and Haemophilus influenzae are key etiologic agents of childhood bacterial meningitis in Korea.
  • * Current vaccination strategies may need re-evaluation for optimal efficacy.
  • * Ongoing nationwide epidemiological studies are crucial for monitoring and adapting immunization strategies.

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...

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 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...

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...
Encephalitis l: Introduction01:19

Encephalitis l: Introduction

Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...

Cryptococcal Meningitis

Cryptococcal meningitis is a life-threatening opportunistic infection predominantly associated with HIV/AIDS, accounting for over 100,000 deaths annually worldwide. However, it also affects individuals with other forms of immunosuppression, including those undergoing immunosuppressive therapy, organ transplant recipients, patients with innate immunodeficiencies, and individuals with hematological disorders. The infection is caused mainly by Cryptococcus neoformans and Cryptococcus gattii,...
