Abstract

Insights

Anaerobic bacteria, like Parvimonas micra, can cause severe pneumonia with empyema in immunocompromised individuals. Next-generation sequencing aided in identifying the pathogen, leading to effective targeted therapy with levornidazole.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Pulmonology

Background:

  • Anaerobic bacterial pneumonia with empyema is a rare but serious condition.
  • Immunocompromised patients are at higher risk for severe outcomes.

Purpose of the Study:

  • To report a case of anaerobic pneumonia with empyema.
  • To highlight the diagnostic utility of next-generation sequencing (NGS).
  • To demonstrate the effectiveness of targeted antibiotic therapy.

Main Methods:

  • Case presentation of a 67-year-old male with diabetes and hypertension.
  • Initial broad-spectrum antibiotics were ineffective.
  • Next-generation sequencing (NGS) was employed for pathogen identification.
  • Targeted therapy with levornidazole was initiated.

Main Results:

  • Next-generation sequencing identified Parvimonas micra as a causative agent.
  • The patient showed significant clinical improvement after targeted levornidazole therapy.

Conclusions:

  • Anaerobic bacteria should be considered in immunocompromised patients with pneumonia and empyema.
  • Next-generation sequencing (NGS) is a valuable tool for identifying challenging pathogens.
  • Prompt and targeted therapy can lead to favorable patient outcomes.

Pneumonia I: Introduction01:30

Pneumonia I: Introduction

Pneumonia is an acute respiratory infection that targets the lungs, specifically the alveoli. These tiny air sacs, essential for oxygen exchange, become engorged with pus and fluid, severely hindering breathing, decreasing oxygen absorption, and causing significant pain and discomfort during respiration.
Risk Factors
Various factors influence the likelihood of developing pneumonia. Age plays a crucial role, with infants, children under two, and individuals over 65 at increased risk due to their...

Pneumonia IV: Management

The treatment of pneumonia varies based on its severity and the causative pathogen. Here is a structured approach to managing pneumonia, integrating pharmaceutical and supportive care strategies.
Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:

Pneumonia V: Nursing management and Prevention

Nursing management of pneumonia involves promoting airway patency, facilitating rest and conserving energy, encouraging fluid intake, maintaining nutrition, and educating patients.
The nurse must practice strict medical asepsis and adhere to infection control guidelines to minimize healthcare-associated infections.
Enhance airway patency
Position the patient correctly to facilitate drainage of the affected lung segments. Manual or mechanical percussion and vibration can also be employed....

Diversity of Protists I01:15

Diversity of Protists I

Excavata is a diverse group of protists that includes both chemoorganotrophic and phototrophic species, with some thriving in anaerobic environments. Among the key groups within Excavata are diplomonads and parabasalids, which are flagellated protists that lack mitochondria and chloroplasts. These microorganisms typically inhabit anoxic environments, such as the intestines of animals, where they exist either symbiotically or as parasites, relying on fermentation for energy production. Some...
