Insights

A rare case of anthrax meningoencephalitis survived due to rapid metagenomic next-generation sequencing (mNGS) diagnosis and effective combination antibiotic therapy. This approach is crucial for improving survival rates in severe Bacillus anthracis infections.

Area of Science:

  • Infectious Diseases
  • Neurology
  • Microbiology

Background:

  • Anthrax meningoencephalitis is a rare and often fatal complication of Bacillus anthracis infection.
  • Early diagnosis and prompt treatment are critical for patient survival.

Purpose of the Study:

  • To report a rare survival case of anthrax meningoencephalitis.
  • To highlight the role of rapid molecular diagnostics and combination therapy in patient recovery.

Main Methods:

  • Case report of a 56-year-old male with anthrax meningoencephalitis.
  • Metagenomic next-generation sequencing (mNGS) for pathogen identification in cerebrospinal fluid (CSF).
  • Administration of CDC-recommended quadruple and triple antibiotic combination regimens.

Main Results:

  • Initial microscopy misidentified Bacillus anthracis as Bacillus cereus.
  • mNGS confirmed Bacillus anthracis in CSF within 48 hours, enabling timely treatment adjustment.
  • The patient achieved full neurological recovery following combination antibiotic therapy.

Conclusions:

  • Rapid mNGS-based diagnosis is vital for identifying Bacillus anthracis in meningoencephalitis.
  • Synergistic combination therapy, guided by rapid diagnostics, significantly improves survival outcomes.
  • This case emphasizes the importance of advanced molecular techniques in managing rare infectious diseases.

Cryptococcal Meningitis01:27

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,...

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...

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.

Brain Abscess l: Introduction

A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
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...

Medical management of tuberculosis (TB) patients involves a comprehensive approach that includes diagnosis, treatment, and monitoring. The specific strategies can vary depending on the type of tuberculosis (latent or active), the patient's overall health status, and other considerations.
Latent tuberculosis infection occurs when TB bacteria are present in a person's body, but are not causing illness or symptoms. It is not contagious, and preventive treatment is crucial to avoid the progression...
