Summary
This case report details a rare instance of parotitis caused by Mycobacteroides abscessus subspecies abscessus (MAB). Prompt identification and tailored antibiotic therapy are crucial for treating this intractable MAB infection.
Area of Science:
- Infectious Diseases
- Microbiology
- Otolaryngology
Background:
- Parotitis is uncommon, with rapidly growing mycobacteria rarely implicated.
- Mycobacteroides abscessus subspecies abscessus (MAB) is an emerging pathogen.
Observation:
- A previously healthy 26-year-old woman presented with persistent right parotid swelling and abscesses.
- Initial diagnostics revealed granulomatous inflammation and acid-fast bacilli, but failed mycobacterial culture.
- The parotitis persisted despite multiple antibiotic courses and surgical interventions.
Findings:
- Definitive diagnosis identified MAB after extensive tissue resection and culture.
- This represents the first documented case of parotitis specifically attributed to MAB, with its subspecies identified.
- MAB proved more challenging to treat than other subspecies.
Implications:
- Accurate identification of MAB is critical for effective treatment strategies.
- Highlights the need for considering MAB in refractory parotitis cases.
- Emphasizes the importance of advanced microbiological techniques for pathogen identification.

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 (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:

Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...

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...
