Summary
Mycobacterium marinum infections, often from water exposure, can cause rare bursitis. Minocycline effectively treated both skin nodules and bursitis in a patient.
Area of Science:
- Infectious Diseases
- Dermatology
- Rheumatology
Background:
- Mycobacterium marinum infections are linked to water exposure and trauma.
- Sporotrichoid nodule distribution is a characteristic presentation.
- Differential diagnosis for cutaneous and joint infections is crucial.
Observation:
- A case of Mycobacterium marinum infection presenting with sporotrichoid nodules and bursitis.
- Diagnosis confirmed by skin tissue culture and histopathology.
- Simultaneous joint and skin involvement presented a diagnostic challenge.
Findings:
- Minocycline treatment led to resolution of bursitis and nodules within 2 months.
- A 6-month course of minocycline was completed.
- Complete resolution of symptoms was achieved.
Implications:
- Bursitis is a rare but significant complication of Mycobacterium marinum.
- Early diagnosis and appropriate antibiotic treatment are essential for favorable outcomes.
- This case highlights the importance of considering M. marinum in patients with relevant exposure history and suggestive clinical findings.

01:31Pulmonary Tuberculosis III
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:

01:30Bacterial Phylum Actinobacteria
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...
01:24Bacterial Meningitis
Bacterial meningitis is a severe infectious disease involving inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. It occurs when pathogenic bacteria cross the blood–brain barrier and enter the cerebrospinal fluid. Common causative organisms include Neisseria meningitidis, Streptococcus pneumoniae, Haemophilus influenzae type b, Listeria monocytogenes, and Escherichia coli K1. The exact route of entry varies by pathogen and host condition.Routes of Entry...
01:14Atypical Pneumonia
Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
01:23Tuberculosis
Tuberculosis (TB) remains a significant global health concern, primarily targeting the lungs and spreading through airborne transmission. Infection begins when aerosolized droplet nuclei, expelled by an individual with active TB, are inhaled by another person. These microscopic particles carry Mycobacterium tuberculosis, the causative agent of TB. Upon reaching the alveoli, the bacilli are engulfed by alveolar macrophages. However, due to their specialized lipid-rich cell wall, these pathogens...
01:25Clinical 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...
