Abstract

Insights

This report details a rare case of Clostridium meningitis and Plesiomonas sepsis in an immunocompetent adult. The patient presented with rapid deterioration and death, with both bacteria identified post-mortem without a clear entry point.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Neurology

Background:

  • Anaerobic bacterial meningitis is a rare condition.
  • Cases are typically associated with trauma or neurosurgery, making cases without a clear portal of entry extremely unusual.

Purpose of the Study:

  • To report a unique case of concurrent Clostridium meningitis and Plesiomonas sepsis.
  • To highlight the occurrence of these infections in an immunocompetent adult without an identifiable portal of entry.

Main Methods:

  • A case report of a 71-year-old male with diabetes.
  • Clinical presentation included acute severe headaches, obtundation, and hemolysis after a hunting trip.
  • Post-mortem cerebrospinal fluid (CSF) and blood analyses were performed.

Main Results:

  • Clostridium perfringens was identified in both CSF and blood.
  • Plesiomonas shigelloides was identified in the blood.
  • The patient experienced rapid clinical deterioration and death within 3 hours of presentation.

Conclusions:

  • This is the first reported case of simultaneous bloodstream infection with Clostridium perfringens and Plesiomonas shigelloides in a single patient.
  • The absence of an obvious portal of entry in this case challenges typical understanding of these infections.

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...

Bacterial Gastroenteritis

Bacterial gastroenteritis, characterized by diarrhea, abdominal cramps, and vomiting, is often caused by ingestion of contaminated food or water and is frequently associated with pathogenic Escherichia coli strains. These microbes exploit two principal mechanisms to inflict disease.Shiga toxin–producing E. coli, also referred to as STEC—notably O157:H7—release Shiga toxins that target ribosomes, blocking protein synthesis. The B subunit of the toxin binds the host glycolipid receptor...
Reservoir of Infection01:30

Reservoir of Infection

Infectious diseases arise from intricate interactions between pathogens and their reservoirs. A reservoir of infection refers to the natural habitat where a pathogen lives, grows, and multiplies, serving as a continual source of infection. Reservoirs are broadly classified as either living or nonliving, and each plays a unique role in disease transmission, significantly influencing public health interventions and control strategies.Humans act as reservoirs for a wide array of pathogens,...
Clinical Significance of Antibiotic Resistance01:25

Clinical Significance of Antibiotic Resistance

Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
Bacterial Toxins01:12

Bacterial Toxins

Bacterial toxins are sophisticated virulence factors that enable pathogenic bacteria to interact with, invade, and damage host tissues. These toxins fall broadly into two types: protein exotoxins, which are secreted into the environment and target specific host receptors, and lipopolysaccharide endotoxins, which are structural components of the bacterial outer membrane released primarily during bacterial lysis or membrane shedding. Exotoxins generally act more selectively, binding to cell...
