Insights

Bacterial meningitis etiology in Turkish children was determined using multiplex PCR. Neisseria meningitidis, Streptococcus pneumoniae, and Hib were identified, highlighting the need for broad meningococcal vaccines.

Area of Science:

  • Pediatric Infectious Diseases
  • Microbiology
  • Vaccinology

Background:

  • Bacterial meningitis prevention relies on understanding causative agents.
  • Etiological determination is crucial for effective vaccination strategies.

Purpose of the Study:

  • To determine the bacterial etiology of meningitis in children in Turkey.
  • To inform vaccination policies by identifying prevalent bacterial pathogens.

Main Methods:

  • Prospective collection of cerebrospinal fluid (CSF) samples from hospitalized children (1 month to 18 years).
  • Multiplex polymerase chain reaction (PCR) used to detect DNA of Neisseria meningitidis, Streptococcus pneumoniae, and Hemophilus influenzae type b (Hib).

Main Results:

  • Bacterial etiology was identified in 44.4% of 1452 CSF samples.
  • Neisseria meningitidis was the most frequent isolate (51.6%), followed by Streptococcus pneumoniae (30.2%) and Hib (18.1%).
  • Among N. meningitidis isolates, serogroup W-135 was most common (38.1%), followed by serogroup B (26.1%).

Conclusions:

  • Available vaccines target the most frequent bacterial isolates identified.
  • Results underscore the necessity for comprehensive meningococcal disease protection in Turkey.

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...
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...
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...
Bacterial Meningitis I: Introduction01:22

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 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...
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...
