Insights

Salmonella meningitis in children increased significantly, with a high mortality rate despite chloramphenicol treatment. This suggests a need for new antibiotic strategies for bacterial meningitis.

Area of Science:

  • Pediatrics
  • Infectious Diseases
  • Microbiology

Background:

  • Salmonella meningitis is a severe form of bacterial meningitis.
  • An increase in Salmonella meningitis cases was observed between 1996 and 1999 compared to 1982.
  • This rise may be linked to the increasing prevalence of Human Immunodeficiency Virus (HIV) infection and subsequent Salmonella septicemia.

Purpose of the Study:

  • To analyze the incidence, clinical features, and outcomes of Salmonella meningitis in children.
  • To evaluate the effectiveness of current treatment protocols.

Main Methods:

  • Retrospective review of 61 cases of Salmonella meningitis from February 1996 to January 1999.
  • Analysis of patient demographics, nutritional status, clinical presentation, treatment, and outcomes.
  • In vitro susceptibility testing of Salmonella isolates to chloramphenicol.

Main Results:

  • Salmonella meningitis constituted 6.8% of acute bacterial meningitis cases during the study period.
  • The majority of affected children were under 2 years old, malnourished, and anemic.
  • Mortality was high (58%), with significant morbidity in survivors.
  • Relapse occurred in two patients, one of whom died.
  • All isolates were sensitive in vitro to chloramphenicol.

Conclusions:

  • The high mortality and morbidity associated with Salmonella meningitis underscore its severity.
  • Current treatment with chloramphenicol appears inadequate, despite in vitro sensitivity.
  • An alternative antibiotic policy is urgently needed to improve outcomes for children with Salmonella meningitis.

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 Meningitis01:24

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...

Cholera

Cholera is an acute gastrointestinal disease caused by the Gram-negative bacterium Vibrio cholerae. It is transmitted primarily via the fecal-oral route through the ingestion of contaminated water or food.Vibrio cholerae is a motile, Gram-negative bacterium of the family Vibrionaceae, primarily associated with waterborne outbreaks in areas with inadequate sanitation. Although over 200 serogroups of V. cholerae exist, only O1 and O139 are responsible for epidemic cholera. The O1 serogroup,...

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...
