Abstract

Insights

Bacterial co-infections in infectious mononucleosis (IM) are uncommon. Fusobacterium necrophorum does not appear to be a significant cause of acute tonsillitis or peritonsillar abscess (PTA) in IM patients.

Area of Science:

  • Otolaryngology
  • Infectious Diseases
  • Microbiology

Background:

  • Investigating bacterial co-infections in infectious mononucleosis (IM) with acute tonsillitis and peritonsillar abscess (PTA).
  • Examining the potential role of Fusobacterium necrophorum in severe IM cases.
  • Understanding the prevalence of bacterial pathogens in IM-related throat infections.

Purpose of the Study:

  • To determine the prevalence of bacterial co-infections in patients with infectious mononucleosis (IM) and acute tonsillitis or peritonsillar abscess (PTA).
  • To assess the specific role of Fusobacterium necrophorum in these conditions among teenagers and young adults.

Main Methods:

  • Retrospective study of patients with IM and acute tonsillitis or PTA from 2001-2015.
  • Analysis of bacterial cultures from patients to identify pathogens.
  • Correlation of bacterial findings with clinical diagnoses.

Main Results:

  • Bacterial cultures were positive in 28% of acute tonsillitis and 50% of PTA cases.
  • Group C/G streptococci were most common in acute tonsillitis (14%), while Staphylococcus aureus predominated in PTA (22%).
  • Fusobacterium necrophorum was found in 9% of acute tonsillitis and 2% of PTA cases, not supporting a prevalent role.

Conclusions:

  • Fusobacterium necrophorum does not appear to be a common cause of acute tonsillitis or PTA in patients with IM.
  • Staphylococcus aureus may contribute to PTA development in IM patients.
  • Antibiotic use is not generally supported for IM, even with severe symptoms or high PTA risk.

Separation of Immune Cell Subpopulations in Peripheral Blood Samples from Children with Infectious Mononucleosis

We describe a method combining immunomagnetic beads and fluorescence-activated cell sorting to isolate and analyze defined immune cell subpopulations of peripheral blood mononuclear cells (monocytes, CD4+ T cells, CD8+ T cells, B cells, and natural killer cells). Using this method, magnetic and fluorescently labeled cells can be purified and...

In Vitro Selection of Aptamers to Differentiate Infectious from Non-Infectious Viruses

We provide a protocol that can be generally applied to select aptamers that bind to infectious viruses only and not to viruses that have been rendered non-infectious by a disinfection method or to any other similar viruses. This opens the possibility of determining infectivity status in portable and rapid...

Hemodialysis II: Procedure and Complications

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Virus Plaque Assay: A Technique to Measure Infectious Herpes Simplex Virus via Quantification of Plaques Formed in Monolayer of Virus-Infected Cells

This video describes the virus plaque assay of the infectious herpes simplex virus or HSV. The diluted viral particles are inoculated to the monolayer of epithelial cells. Upon incubation, the virus forms plaques and is counted visually to determine the infectious virus...
