A Case Report of Corynebacterium Tuberculostearicum Infection
Clinical Laboratory
|March 12, 2024
Summary
A rare case of lymphadenitis caused by Corynebacterium tuberculostearicum was identified using advanced laboratory techniques. This study enhances understanding of this uncommon infection and guides future diagnosis and treatment strategies.
Area of Science:
- Medical Microbiology
- Infectious Diseases
Background:
- Reporting a rare case of lymphadenitis caused by Corynebacterium tuberculostearicum.
- Highlighting the laboratory's approach to isolating and identifying this rare pathogen.
Observation:
- A lymph node biopsy was performed on a patient with suspected tuberculous lymphadenitis.
- The biopsy tissue was cultured for pathogen identification.
Findings:
- Gram-positive Corynebacterium identified as Corynebacterium tuberculostearicum via mass spectrometry and 16S rRNA sequencing.
- Antimicrobial susceptibility revealed sensitivity to daptomycin, doxycycline, gentamicin, linezolid, vancomycin, and meropenem.
- Resistance was observed against ciprofloxacin, clindamycin, erythromycin, rifampicin, compound sulfamethoxazole, ceftriaxone, and cefepime.
Implications:
- This case contributes to the limited reports of Corynebacterium tuberculostearicum infections, particularly in China.
- Provides valuable insights for laboratory isolation, identification, and clinical management of this rare bacterium.

Tuberculosis, or TB, is a bacterial infectious disease caused by Mycobacterium tuberculosis. While its primary impact is on the lungs, leading to pulmonary tuberculosis, it can also affect various other organs, a condition referred to as extrapulmonary tuberculosis.
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Tuberculosis, often called TB, is a contagious illness primarily caused by Mycobacterium tuberculosis. It mainly affects the lung parenchyma but can also impact other body parts.
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Tuberculosis, more commonly referred to as TB, is an infectious disease stemming from Mycobacterium tuberculosis. While it primarily impacts the lungs, TB can also affect other body areas. Given its severity and global impact, timely and accurate diagnosis is crucial for controlling its spread and improving patient outcomes.
Several diagnostic approaches are used to detect TB. The conventional method is the Tuberculin Skin Test (TST), also known as the Mantoux test. However, this method has...

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...

Tuberculosis (TB) is a contagious infection primarily affecting the lung parenchyma but which can also affect other body parts. TB can be classified based on disease development, presentation, and the affected anatomical site.
The first classification is based on the development of the disease, and it includes the following categories:

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...
