Insights

Salmonella meningitis is rare but serious, particularly in infants. This study found Salmonella caused 3.43% of bacterial meningitis cases, with S. typhimurium being the most common and drug-resistant strain.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Microbiology

Background:

  • Bacterial meningitis poses a significant threat, especially to young children.
  • Salmonella species are known pathogens, but their role in meningitis requires ongoing surveillance.

Purpose of the Study:

  • To determine the incidence of Salmonella meningitis.
  • To identify the specific Salmonella serotypes involved.
  • To assess antimicrobial resistance patterns of isolated Salmonella strains.

Main Methods:

  • A retrospective analysis of bacterial meningitis cases was conducted.
  • Cerebrospinal fluid (CSF) and blood cultures were examined for Salmonella isolation.
  • Antimicrobial susceptibility testing was performed on isolated strains.

Main Results:

  • Salmonella was identified in 3.43% (8/233) of bacterial meningitis cases.
  • Seven of the eight Salmonella meningitis cases occurred in children under two years old.
  • Salmonella typhimurium (4 cases) was the predominant isolate, exhibiting multi-drug resistance; Salmonella typhi (3 cases) remained sensitive to common antibiotics.

Conclusions:

  • Salmonella meningitis is an infrequent but critical diagnosis, predominantly affecting infants.
  • The emergence of multi-drug resistant Salmonella typhimurium in meningitis cases necessitates careful antibiotic selection.
  • Surveillance of Salmonella meningitis and its antimicrobial resistance profiles is crucial for effective public health management.

Investigation of Disease Outbreaks

Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...

Rocky Mountain Spotted Fever

Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.

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...

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: 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...
